Megapixel Cameras and Image Quality

If you’re in the market for a security system a major component you’re probably considering is video surveillance.  While doing a little research you’ve likely come across a plethora of surveillance options with various technological features.  It may seem like a daunting task to choose the cameras that suit your needs, which is why you should always consult a licensed security systems professional.  They’ll be able to assess the security risks associated with your facility and provide optimal solutions.  Our team at Perfect Connections, Inc. has been providing comprehensive security systems to businesses throughout northern and central New Jersey for the over 25 years.  We understand the process and can help you protect what matters most.  Our experts are knowledgeable in all aspects of security system integration including surveillance.  Whether or not you’ve done your own research it’s likely you’ve heard or come across the term megapixel.  What does that mean in regards to surveillance systems, and what are the advantages/disadvantages?

640px-Definitions_of_TV_standards To understand the relationship between megapixels and video surveillance let’s first figure out what megapixel means.  A pixel is a “picture element residing on the image sensor (in a camera).”  The quantity of pixels helps determine the resolution of an image.  All megapixel cameras have a minimum of 1,000,000 pixels which means the image is comprised horizontally and vertically 1,000 x 1,000 pixels.  In recent years there has been an increased demand for megapixel surveillance cameras over the standard definition cameras widely used in the past.  Standard resolution cameras typically have a resolution of approximately 400,000 pixels.

To get an idea of the difference between image resolutions the picture above shows three variations.  The front image shows a standard resolution of 576 pixels, the middle shows an HD (High Definition) resolution of 720 pixels, and the last image shows an HD 1080 pixel resolution.  While most consider all HD cameras to fall under the megapixel category Raul Calderon, senior vice president of marketing for Arecont Vision, says that HD cameras with a 720 pixel resolution are not technically a megapixel camera as the resolution only adds up to 921,600 pixels.  A major difference between HD and megapixel cameras is HD cameras have to comply with set standards whereas megapixel cameras simply refer to the number of pixels.

A major advantage to investing in megapixel camera technology is the ability to use less cameras to cover larger areas.  With standard definition IP (Internet Protocol) or network cameras coverage is significantly limited and typically requires more cameras and cabling.  Megapixel cameras require less cabling and therefore the cost of labor and cabling is typically less than installing standard resolution cameras.  The ability to digitally zoom-in on an image without losing clarity is another benefit of utilizing megapixel cameras.  Megapixel recordings are clearer than standard resolution cameras therefore more consumers are storing footage for longer periods of time, which can be helpful in solving crimes.  They decrease the need for constant live monitoring as the footage can be revisited with ease.  Other benefits include a long lifespan, they conserve energy, and they are low maintenance.

Megapixel cameras not only benefit the owner but different industries as well.  With more quality recorded footage being stored the more the recording and storage industries will grow.  As megapixel cameras become more ubiquitous, technologies used in conjunction with them will grow and change.  For example the types of video displays and lenses will likely become more developed.  While there are many benefits to megapixel cameras the potential drawbacks include initial cost of installation and the challenge of keeping up with the fast paced technological changes.  Fortunately, as these types of cameras become more widely used their pricing will be driven down.  As far as technological advancements are concerned there will always be changes and improvements it’s a matter of security system experts providing ease of integration and updates.

While you now have a little background on megapixel cameras and their advantages/disadvantages, it’s still imperative to contact a licensed professional for your security needs.  They’ll be able to assess the specific security risks associated with your facility and which products will work best.  Our team of experts at Perfect Connections, Inc. have been providing professional service to businesses and facilities throughout northern and central New Jersey since 1992.  We understand the complexities involved in creating a comprehensive security system that is tailored to your needs.

The Smart Way To Store Footage

Surveillance playSAN-Dennis van Zuijlekoms a vital role in any comprehensive security system. It helps authorities catch criminals and provides helpful insight into your business operations by collecting and analyzing data on a daily basis. Where and how is all of this visual and analytical data being “collected?” That is the ever pressing question for system integrators and end-users alike. Storing surveillance data can be as important to the efficiency of your security system as having the surveillance equipment itself. We are catapulting ourselves into the future with the constant evolution of technology in all aspects of life including security system components, and surveillance storage solutions are no exception, but not all are created equal.

At Perfect Connections, Inc. our licensed integrators are dedicated to providing comprehensive security system solutions that protect people and property. We have been installing security systems at business facilities throughout northern and central New Jersey for over 25 years. Our team designs system solutions that meet the needs specific to your organization. Surveillance storage is a security system component that will vary project to project and should be treated with an individualized approach.

In the not so distant past, video recordings weren’t as advanced as they are today in terms of image resolution, clarity, and noise distortion. Recordings would often be deemed unusable due to their lack of clarity and they would typically be discarded freeing up storage space for new recordings. Today, with the advent of IP cameras (internet protocol) and more advanced camera technology the recordings have become critical data sources that are considered valuable. This means more and more end-users are interested in keeping recorded data for longer periods of time. The obvious consequence is the need for more storage space.

There are many factors that affect what kind of surveillance storage solutions can and should be implemented at a facility. The size of the project, existing infrastructure, and client budget are all critical determinants as to what type of storage should be implemented. The camera type, camera quantity, compression standards, frame rates, motion detection, desired length of storage, and overall estimate of desired resolution all should be taken into account as well.

When it comes to storing surveillance data it is paramount that the integrity of the footage is not lost. Traditionally surveillance footage would be stored on a DVR (digital video recorder), but it’s limitations within a networked system make it less than ideal. With so much of the surveillance world developing around IP and network solutions it’s only natural that network storage solutions should arise. NAS (network attached storage), SAN (storage area network), and DAS (direct attached storage) are all potential methods for storing surveillance data. All have different installation requirements. Some may call for extensive cabling and a large closet to store servers, but it all depends on the size and type of project. According to Justin Schorn, vice president of product management for Aimetis, “The critical decision is choosing between a storage area networks (SAN) and network attached storage (NAS).”

The different storage devices vary in how they present information to the user and how data is accessed. The NAS devices present data in a “file system” same with DAS, whereas SAN is presented in what is referred to as “block storage.” DAS and NAS either attach directly to an existing network or the NVR (network video recorder). SAN is essentially an extension of a DAS, but provides a higher storage capacity.

DAS is typically implemented in situations when expansion is not an option, the system performance requisites are static, and shared access is not necessary. The reason being is DAS devices are limited to singular DVR or NVR applications. SAN solutions are typically used in larger camera applications that may later require scalable options. According to Lee Caswell, founder and chief marketing officer at Pivot3, “Many archivers can share the storage and the SAN platform introduces more reliability over NVR/DVR systems because there is no single point of failure.” Common applications for SAN storage include airports, casinos, and prisons.

NAS devices are typically used in smaller surveillance applications as its performance isn’t as robust as SAN. One of the advantages to NAS solutions is data can be easily accessed by anyone on the same protected network. Lee says, “The advantage of the file system on the NAS platform is that it is easier to support a hybrid storage case as some storage occurs locally on self-contained NVRs/DVRs and extended storage is sent to a specific file on the NAS.”

Keeping high quality recorded data for longer periods of time can help local authorities with investigations and it can provide insight into your business that you otherwise wouldn’t observe. While storing recorded footage from your surveillance system is critical to your overall security, it’s important to remember that the type of storage necessary will vary depending on the project parameters. It is imperative to work with a licensed security system integrator to help evaluate security risks, the quantity of cameras needed, and how a surveillance storage system can be implemented to meet your requirements. At Perfect Connections, Inc. we are committed to providing security systems that suit your specific needs. We have been designing and installing comprehensive security systems at businesses throughout northern and central New Jersey since 1992.

Bridging The Gap From Analog to IP Cameras

Mike Mozart-surveillanceAs a business owner protecting your facility is always a top concern. Are you getting the coverage you need? If you have a comprehensive security system you’re already in a good position. However, a security system is only as good as the sum of its parts. One of the most crucial parts of a security system is the surveillance aspect. Surveillance systems are the eyes that keep watch over your business even when you can’t.

Like any other technology surveillance equipment is constantly evolving through research and development that is meant to improve its efficiency. In today’s IoT (Internet of Things) IP-based (Internet Protocol) systems are a driving force that is changing the role of surveillance in comprehensive security. But not everyone is so keen on the uptake. Prior to the inception of IP cameras and network devices the world was and has been dominated by analog cameras and DVR devices (Digital Video Recording). If you have existing surveillance equipment, chances are it’s a legacy analog system, which is why its important for you to start bridging the gap from an analog to an IP camera system.

While the IP surveillance trend is picking up, there are still more than 40 million analog cameras in operation around the world today. Making the switch from analog to IP isn’t an easy transition for everyone and integrators have become increasingly aware. Fortunately there are hybrid solutions that allow you to work with your existing analog infrastructure and start your migration to an IP-based system. At Perfect Connections, Inc. our team of licensed integrators work with you to provide comprehensive security solutions that meet your needs. Our experts have been providing comprehensive security system solutions, including surveillance, to businesses throughout northern and central New Jersey for that past 23 years. We recognize the value technology adds to the security systems we install and how they can benefit our customers.

Why replace an analog system? To be fair, analog systems have filled a security need since the beginning of surveillance that would have otherwise gone unfulfilled. But just like any technology, progress is always pushing the envelope of what is relevant and effective. Look at smartphones, they are constantly evolving, every year a new model with new features that jettisons society forward. While businesses aren’t necessarily turning over their surveillance systems at the same rate, the growing trend is leaning towards IP and network based solutions.

Hybrid solutions for companies that aren’t ready to make the full switch to IP just yet offer the benefits of a more effective system that will ease the transition when the time is right. According to Mark Collett, general manager of Sony Security Systems Division, “With hybrid solutions, you can get the best of both worlds—the near-zero latency of analog plus IP’s HD imaging quality.”

Video encoders are the catalyst for the hybrid solution, replacing out of date and expensive DVRs. DVRs were traditionally responsible for storing and recording footage captured by connected surveillance cameras. According to James Marcella, a technologist in the security and IT industries, a video encoder is, “an open-platform technology that acts as a bridge between the analog and digital world by essentially turning an analog investment into IP cameras.” Video encoders would allow you to make use of existing infrastructure by attaching to the coaxial cable from you analog system, transforming the analog signal into a digital stream.

Many industry experts consider DVRs to be one of the most expensive pieces of equipment the consumer will purchase, and they are typically outlived by the analog cameras. Also, they are not dependable, if they go down so does the whole surveillance system, and this could happen at a critical moment. Video encoders are capable of running on power over Ethernet that can be tied to a backup power supply, keeping you covered no matter what. You can also employ redundancies like NAS devices (Network Attached Storage) and SD memory cards to help prevent recording loss.

DVRs lack the image resolution, edge intelligence, and network capabilities that a video encoder can offer. The frames per second rate (fps) is what creates a smoother clearer image, the higher the better especially in high motion scenarios. Video encoders are capable of capturing images at up to 60fps whereas DVRs only go up to 15fps. DVR intelligence is typically limited to whatever the manufacturer specifications have been set to. Video encoders open the door to third party intelligent applications which allow you to choose video management software from virtually any provider in the connected world. This creates a platform for advanced video analytics.

There is a large storage and scalability disparity between DVRs and video encoders. DVRs typically have a low tolerance for the quantity of cameras they can accommodate which can leave a business vulnerable by not being able to cover risky areas. On the other hand video encoders offer virtually limitless retention by being highly scalable. Video encoders have the ability to accommodate single cameras and there are some units that can accommodate up to 84 cameras making them a highly flexible and effective solution for a large or small facility.

The hybrid solution allows you to keep existing analog cameras and infrastructure and as the cameras die or warrant replacement, they can easily be swapped out for IP creating a smoother transition. Remote monitoring is another benefit to opting for a hybrid solution. This adds a level of security you can’t obtain from an analog system, being able to login to your surveillance system to see what is going on at your facility when you can’t be there.

Hybrid solutions are an economic and less disruptive option if you’re not fully committed to taking the IP plunge, even though progress will continue to push us in that direction. If you opt for a hybrid solution or aren’t sure what to do always consult a licensed professional to ensure proper application and installation. At Perfect Connections, Inc. our licensed integrators have been providing comprehensive security solutions to businesses throughout northern and central New Jersey since 1992. We can guide you through the process of creating a system that meets your specific needs, from an initial assessment to final installation.

Understanding Wide Dynamic Range

When it comes to surveillance cameras, visibility is key.  Some of the obstacles surrounding a camera’s capability to retain clear images such as lighting, camera installation, and type of camera are somewhat within our control, others are not.  Uncontrollable issues of extreme brightness, like light produced from headlights and the sun, or extreme darkness are not necessarily easily overcome.  However, as with anything, technological progression helps change these harrowing limitations.  As industry professionals our team at Perfect Connections, Inc. has been providing security system solutions, including surveillance, to organizations throughout northern and central New Jersey for the past 23 years.  We’ve seen the impact changing technology has on the equipment we install and how it can be beneficial to our customers.

Surveillance systems are in the midst of a transition from using conventional analog equipment to IP (Internet Protocol).  Why? For one, image quality.  The tricky thing with IP cameras is not all are created equal.  There isn’t necessarily a defined industry standard that is accepted by all integrators and camera manufacturers when it comes to “best” image quality.  For example some might argue that the higher the megapixel count the better, but it doesn’t necessarily guarantee a better image.  At least with HD (high definition) cameras there are standards manufacturers must comply with in order to be considered HD.

Aside from pixel count, an IP camera’s display threshold in extreme conditions is critical, but limited.  This limit, specifically when referring to extreme brightness or darkness, is typically known as “dynamic range.”  Wide dynamic range (WDR), “allows cameras to capture much more detail in scenes where there are varying levels of light, much like the way the human eye ‘processes’ these types of scenes.”  You know the feeling of widening your eyes in the dark to try to see clearer because you’re eyes haven’t quite adjusted yet?  It’s sort of the same idea with WDR cameras and how they adapt in both light and dark conditions.  However, their adjustments aren’t a physical strain and transitions are typically quicker than ours.

WDR footageThe images above show the difference between a parking garage being monitored by a camera with no WDR or WDR turned off on the left, and on the right the same area monitored by a camera with WDR enabled.  The difference is clear as day.  Why do they differ so much?  The camera with the WDR enabled has two internal Charge-Coupled Devices (CCD).  The two devices, or sensors, scan an image at different speeds, one low and one high, the image processor then combines the separate images producing a clearer, more balanced picture with better contrast and lighting.  This process happens quickly enough to produce a stream of clear recorded footage.  There are many different manufacturers that produce these WDR cameras in the market today, and not all of them use the same type of sensor and image processing combinations.  The best way to ensure you are getting the best camera for your specific application is to hire a licensed security systems integrator who is educated in which camera specifications will work best in variant conditions.

WDR technology, like anything else, is not perfect.  Depending on the camera manufacturer, you could end up with a camera that takes up to 15 seconds to adjust with varying light levels.  That doesn’t sound like that long, but it could mean the difference between catching a perpetrator and them getting away.  Another issue you might run into are cameras that don’t have the ability to turn WDR settings on and off automatically.  Without the automation the transition becomes the responsibility of someone on site, which can be time consuming and ineffective in a time sensitive situation.  This is why it is vital to consult a professional security systems integrator who is educated in the differences between product specifications and their appropriate applications.

The clarity of recorded video footage is crucial to the security of any organization.  As a business owner you don’t want to be left wondering why your recordings are grainy, washed out, or so dark they become unusable.  No one can control the external factors that affect an organization, but you can be prepared for them by taking the proper precautions.  Licensed system integrators are there to help.  Our team at Perfect Connections, Inc. has been providing comprehensive security system solutions to businesses throughout northern and central New Jersey since 1992.  We recognize the importance of utilizing quality security products that not only perform well but perform to their intended specifications.

Using Edge Technology To Protect Your Home Or Business

Todd Huffman-SurveillanceWhen it comes to security systems you may have heard the term “edge technology,” “edge analytics,” or “edge devices.”  What exactly do these terms mean and why are they important?  When talking about security systems “the edge” is typically used when referring to video surveillance components.  Every security system integrator and industry professional will likely have their own definition of what it means, but in summary “edge technology” refers to surveillance devices that operate, analyze, and record at their source versus transmitting all that information over a network to the system’s core.  In traditional surveillance systems there is a central server where recorded data from peripheral devices is stored and analyzed.  In an edge-based system cameras perform these functions locally.

Why is this pertinent information?  Depending on your specific situation using edge-based technology can provide more efficient surveillance processes and enhance the overall effectiveness of your security system.  As every situation is subjective a licensed security systems integrator should always be consulted when determining what type of components will serve your business best.  At Perfect Connections, Inc. our licensed security system integrators are committed to providing comprehensive security systems that exceed your expectations.  We have been installing comprehensive security systems at businesses throughout northern and central New Jersey for the past 23 years.  We know how to assess your security needs and implement relevant technologies that will help keep business running as usual.

Surveillance components that can be considered on “the edge” are IP cameras, video encoders, and network attached storage (NAS) devices.  These devices have recently become more advanced and their capabilities that were once unique to the central server of the security system continue to improve.  According to Steve Gorski, general manager at Mobotix, “Edge-based surveillance solves the bottleneck problem by using the camera to decentralize intelligence and video data.”  This means the cameras themselves are more intelligent and effective.

Edge-based technologies allow for higher image resolutions and the ability to compress them without the loss image quality.  Even with the use of high resolution IP cameras becoming more commonplace, in a traditional system, the images still have to travel to the central server to be stored and typically compressed; this is where image quality can be lost.   Edge technology helps reduce the need for exorbitant storage space on the central server as many edge devices are capable of storing data locally on SD memory cards or NAS devices.  Traditionally these types of storage options were primarily used as backups for the system, but they can now be implemented as the main recording devices in smaller applications.  Cutting down on the need for centralized storage will reduce the need for high bandwidth consumption, ultimately cutting costs.

According to Fredrik Nilsson, general manager for Axis Communications, “It’s estimated today that a staggering 99 percent of all recorded surveillance video is deleted before it’s ever seen.”  How does that make surveillance useful?  It really doesn’t except for use in forensic investigations or after the fact viewing, but with edge-technologies providing intelligence and analytics at the source, detection capabilities increase which creates a more effective system.  With smarter edge devices that can detect patterns, motion, facial recognition, license plates, camera tampering, and people count, you can avoid potential catastrophe that could be caused by deleting recordings to free up space.  These types of analytics provide a platform for real-time viewing that can even be streamed to mobile devices, which are also often considered part of “the edge” realm.  The ultimate goal always being prevention and proactive approaches rather than delayed after the fact reactions.

With any technology “the edge” is a work in progress and will continue to evolve.  It seems edge devices are primarily implemented in smaller applications where the camera need is less than 20.  One of the reasons being a server-based surveillance system can run more analytics per camera because of the CPU power, so the more cameras you have the more processing power you’ll likely need.  For smaller facilities and businesses with remote locations that need surveillance, edge devices are a viable option as they provide real-time analytics, can store footage locally, and don’t require a ton of bandwidth consumption.

At Perfect Connections, Inc. we are committed to providing security system solutions that fit your specific needs.  Our team of licensed integrators has been providing comprehensive security system solutions to businesses throughout northern and central New Jersey since 1992.  We realize that just because a new technology is available that doesn’t mean it is the appropriate solution to every problem.  Our integrators work with you to learn your needs and will design a custom system that addresses your subjective security risks.

A Security System Customized For You

Installing a security sy9677247879_a39e3e702c_zstem can be one of the best ways to protect your business from unpredictable threats like fires and burglars.  Did you know that not all systems are the same?  That’s right there really isn’t a “one size fits all” solution when it comes to securing your workplace, nor should there be.  Why?  Because no two businesses are exactly the same.  Therefore, doesn’t it make sense that a security system should be tailored to a facility’s individual needs?  A healthcare facility wouldn’t have all the same security needs as a retail store, right?  Right.  So how do you go about finding the right system for your business?  Your best option is to hire a licensed professional in the security system field who has extensive knowledge and experience.  At Perfect Connections, Inc. our team has been customizing security system solutions for businesses throughout northern and central New Jersey for the past 23 years.  We understand your business is unique and requires personal attention versus a one-stop solution.

As every home is different and each family has different security needs, the same is true for every business.  There are many factors that go into creating the right system for your facility.  For example the location and demographics, local fire codes and regulations, facility size and type, building/facility access, number of employees, local restrictions, and more.  A business in the middle of a city is going to need a different security system than one located in an industrial park in the suburbs.  This is why it is vital to have a security systems expert do an in person assessment of your facility’s needs before pricing becomes part of the equation.  Don’t fall for the security system company that says they can give you a quote without ever having stepped foot in your facility.

What are the main ingredients for a security system?  At Perfect Connections, Inc. it is our belief that any comprehensive security system includes fire alarms, burglar alarms, access control, surveillance, a monitoring service, and carbon monoxide and smoke detectors.  There are variations on how some of these components are installed and what products are used.  For example there are many different forms of access control.  Access control can be anything from biometrics-which typically analyzes physical human traits like a fingerprint-to smart card readers that require a swipe or tap of a programmed card or fob.

Again, the type of access control that would suit your business best, really depends on what your specific needs are.  Maybe you run a healthcare facility where only certain employees are allowed to access medication supply rooms.  Maybe the best solution in that situation is issuing swipe cards to those specific individuals, or maybe a coded lock would work better.  These are the types of things you want to discuss with your security systems expert.  They will be able to advise you on what system would work best.

Monitoring your alarm system can be varied as well.  While it’s pretty standard to sign a contract with a monitoring service, there is the option to self-monitor as well.  Self-monitoring works by allowing you to access your security system via a smartphone or mobile device.  This type of monitoring could be set up to alert you directly if there is any activity detected at your facility.  The disadvantage to a solely self-monitored system is a slower reaction time and having to constantly be vigilant.  Imagine you don’t have your phone on you and an alarm is triggered at your facility, who’s going to contact the local authorities?  Fortunately, with a monitoring service you don’t have to worry about reaction time because someone is constantly keeping watch.  Even if you opt for a monitoring service often times you can still have the ability to self-monitor at your convenience.  The combination of both gives you the advantage of not having to worry about checking in constantly and the convenience of doing so when you need/want it.

Surveillance is a key component to protecting any business.  How surveillance equipment is set up will vary business to business.  Some facilities may require more or less coverage than others.  Some businesses may be at a higher risk for crime or theft than others as well.  For example Plato’s Closet in Des Moines, IA is susceptible to shrinkage due to clothing, shoe, and accessory theft.  This particular location of Plato’s Closet had a shrink rate of a little over 1 percent, but after they installed 19 IP (Internet Protocol) cameras that rate fell to .8 percent.  The quantity, type, and location of surveillance cameras will depend on an individual business’s needs.

Whether you run a recycling, retail, or healthcare facility protecting your business is a top priority that shouldn’t be left to just anyone.  You need a licensed security systems expert who will assess the risks associated with your business and customize an appropriate solution.  Our team of licensed professionals at Perfect Connections, Inc. understands you’ve worked hard for what you have and we want to help you keep it secure.  We have been providing customized security system solutions to businesses throughout northern and central New Jersey since 1992 helping you connect and protect what matters most.

Cameras and Lighting

West Midlands Police-Infrared FootageNot all surveillance cameras are created equally.  It may seem as simple as selecting a surveillance camera and popping it into place, but what about the external factors that affect the quality of recorded images?  One of the top concerns for industry professionals and end-users alike is a cameras ability to function in the dark or varied light conditions.  Whether you’re using interior or external cameras, their ability to function under varied light conditions is paramount.  Our experts at Perfect Connections, Inc. understand the importance of a surveillance system that doesn’t quit when the sun goes down.  We are a licensed security systems company that has been providing comprehensive security solutions to businesses throughout northern and central New Jersey for the past 23 years.

What challenges do different lighting conditions pose to surveillance cameras?  The most obvious is the absence or lack of light.  Unless your cameras are True Day Night it is likely that they will not be able to pick up fine details in the lack of light.  Another common issue is the effect of light glare.  Problematic glare can come from car headlights to poorly placed exterior lighting fixtures.  Glare will disrupt the sensors in the video camera and the recorded footage can be rendered useless.  It is important to take lighting conditions into consideration when choosing and installing cameras as it will impact the overall effectiveness of your system.  What good is a camera that captures grainy unclear images or blanks out for seconds at a time?

Fortunately there have been vast improvements in the surveillance industry that are changing the game when it comes to light adaptation capabilities.  According to Greg Peratt, Senior Director of the Panasonic Video Solutions Integration Team, there are IP (Internet Protocol) cameras that can capture detailed footage in lighting less than .01 lux illumination.  Lux illumination is the metric measurement for how much light falls on an object.  A measurement of 1 lux, “equals the amount of light that falls on a one-square-meter surface that is one meter away from a single candle.”  Therefore a camera that can capture detailed images in less than .01 lux illumination is not only impressive, it’s advantageous.

Another helpful advancement in the case of low or varied light is the Infrared Cut-Filter Mechanism (IRCF).  This filter is automatically lifted or lowered in front of the camera’s sensor depending on the light levels.  The IRCF helps block out disruptive infrared light that can come from sunlight or certain lighting fixtures and it ultimately improves the camera’s low-light performance.  When light levels are low-typically at night-is when the filter is automatically lifted from in front of the sensor.  Cameras that have this feature are considered to have True Day Night capabilities.

The only hitch with this technology is color is often distorted or lost completely.  However, the camera is still able to capture a clear black and white image and according to Steve Carney it captures an image, “…that is not only vastly more usable but also cleaner without chroma noise.”  Carney points out another differentiator between True Day Night cameras and the impersonators is what happens when the IRCF is lifted or removed.  In a True Day Night camera a piece of “dummy” glass will take the place of the IRCF in order to maintain focus and, “minimize the spectral offset between visible and IR light.”  In other cameras the ability to remove such a filter doesn’t exist, therefore the full spectrum of visible and infrared light cannot be taken advantage of.

Other features to look for when considering Day Night cameras are the shutter speeds and any tinting on the camera housing.  Varying shutter speeds affect the amount of the light that is able to be captured.  The slower the shutter, the more light is captured which isn’t always better.  Often times a camera will come with a domed or “bubble” exterior housing.  These “bubbles” can sometimes be tinted.  Depending on your application you may or may not need tinting; sometimes the tint can have an adverse effect by decreasing visibility and obstructing image clarity.

Whether you are replacing older interior/exterior cameras or installing new, your best solution is to call on the experts.  Every business and facility is different which means each will have different requirements when it comes to day/nighttime surveillance.  Having a licensed security professional do an in person assessment of your facility will help determine what type of camera should be implemented and where.  Our team of licensed professionals at Perfect Connections, Inc. has been providing comprehensive security solutions to businesses and facilities throughout northern and central New Jersey since 1992.  We believe in personalized service that tailors solutions to your individualized needs.

Can I Keep My Camera System On My Office Network?

Network-Norlando PobreWhether you are installing a new surveillance system or changing an existing one you need to consider the type of system and the operating implications associated with it.  The desire for advanced image quality, video analytics, ease of integration, and remote access has ushered in the era of IP (Internet Protocol) surveillance systems.  IP surveillance systems have opened the door to a more integrated security system and they provide increased scalability which is important to company growth and future adaptation.  This type of surveillance system typically relies on an internet network, and as they say “therein lies the rub.”

Should your surveillance system operate on the same internet network as your office computers?  The answer is not a simple yes or no.  The short answer being it certainly is a viable option, but it could depend on the size and type of business you run.  It’s also possible to set up an IP surveillance system on its own network but it may not be cost effective or necessary.  For these reasons it is imperative to consult a licensed security system professional when altering or adding a surveillance system.

When it comes to a company’s network there seems to be some trepidation about how and what devices can and should be allowed on it.  It’s understandable, a company’s network is often a basis for its everyday functions, but where does the worry come from?  A lot of it usually has to do with a communication gap between security integrators and IT professionals or end users.  At Perfect Connections, Inc. our licensed experts are able to provide clear and understandable information about the surveillance equipment we implement and how it will affect your company’s network.  We have been providing comprehensive security system solutions to businesses throughout northern and central New Jersey since 1992.  Our team has witnessed and been a part of the migration from mainly analog surveillance to IP.

Let’s discover the common concerns about network devices and how they can be dissolved, but first we’ll review some quick terminology when talking about networks.  LAN, MAN, and WAN are three basic types of networks you’ll likely hear about from integrators and IT professionals.  Local area networks (LANs) are typically found at most small to medium sized businesses as they cover a smaller more specific area.  In all likelihood your company operates on a LAN network.  Metropolitan area networks (MANs) cover a larger area and are usually present in cities and across large campuses.  Wide Area Networks (WANs) provide the most coverage, anything from expansive distances to the whole world.  According to Fredrik Nilsson, general manager for Axis Communications in North America, WANs are often comprised of multiple smaller networks including LANs and MANs.

All networks are comprised of some sort of cabling and equipment such as switches, servers, and hubs.  The most popular type of network configuration used with LANs is called star.  A star configuration allows all network devices to be connected to a central point where if one device crashes the rest will remain in operation.  However, redundancies are typically incorporated to account for the possibility of a central station crash.

Now that terminology is out of the way, what are some of the major concerns one might have when adding surveillance equipment to a company network?  One of the most common is bandwidth consumption.  This often stems from companies that have had to deal with employees streaming or downloading videos via company networks which eats into the available bandwidth.  According to James Marcella, director of technical services for Axis Communications, IP surveillance equipment is wrongly accused when it comes to bandwidth consumption.  He says most IP cameras today can be customized to fit a company’s network and storage guidelines.  To help limit their consumption surveillance can be setup on a Virtual LANs (VLANs) which Marcella says, “prevents video traffic from grabbing the lion’s share of bandwidth.”

Then there’s the ever-present question, “what about hacking?”  In our world where virtually everything is connected through the IoT (Internet of Things), it’s hard not to worry about who can access private information and how that information is being protected.  Having surveillance equipment on the same network as your company computers may seem scary, but in reality, more oft than not, there are procedures in place to prevent hacker access.

When it comes to adding network devices and keeping the network safe authentication protocol and data encryption are key.  According to Marcella authentication protocol protects the network at the physical port level.  If someone were to unplug a network camera and try to plug in their own device, all “traffic” to that port’s switch would automatically be shut down as the foreign device wouldn’t have the proper authorization.  Data encryption is essentially creating a password to your network whether it’s wired or wireless.  This prevents someone from getting into your network or freeloading on your company’s internet.  Encryptions can be highly effective as long as they are not something obvious or easily guessed.

Lastly, network storage is a top concern.  This is often directly linked to bandwidth consumption concerns.  Due to high image quality of IP camera recordings it’s not uncommon for businesses to store video footage for longer periods of time.  Fortunately, with IP surveillance systems you don’t necessarily have to store recordings directly on the network.  For smaller installations there is the option to utilize in-camera storage through internal SD cards (Secure Digital Cards).  Network Attached Storage (NAS) devices and cloud-based systems are other viable options.  In order to determine which method is best for your company an evaluation of camera quantity and storage needs should be conducted.

Whether you are adding a new surveillance system or updating an existing one it’s imperative to consider the impact it will have on your company’s network, if any at all.  Always consult a licensed security system professional as they can help guide you or your IT department through the process from initial assessment to final installation.  Our team at Perfect Connections, Inc. has been providing comprehensive security solutions to businesses throughout northern and central New Jersey for the past 23 years.  We can help break down the communication barrier that sometimes creates apprehension when installing network devices.

How Do You Store Camera Footage?

Surveillance playSAN-Dennis van Zuijlekoms a vital role in any comprehensive security system. It helps authorities catch criminals and provides helpful insight into your business operations by collecting and analyzing data on a daily basis. Where and how is all of this visual and analytical data being “collected?” That is the ever pressing question for system integrators and end-users alike. Storing surveillance data can be as important to the efficiency of your security system as having the surveillance equipment itself. We are catapulting ourselves into the future with the constant evolution of technology in all aspects of life including security system components, and surveillance storage solutions are no exception, but not all are created equal.

At Perfect Connections, Inc. our licensed integrators are dedicated to providing comprehensive security system solutions that protect people and property. We have been installing security systems at business facilities throughout northern and central New Jersey for the past 23 years. Our team designs system solutions that meet the needs specific to your organization. Surveillance storage is a security system component that will vary project to project and should be treated with an individualized approach.

In the not so distant past, video recordings weren’t as advanced as they are today in terms of image resolution, clarity, and noise distortion. Recordings would often be deemed unusable due to their lack of clarity and they would typically be discarded freeing up storage space for new recordings. Today, with the advent of IP cameras (internet protocol) and more advanced camera technology the recordings have become critical data sources that are considered valuable. This means more and more end-users are interested in keeping recorded data for longer periods of time. The obvious consequence is the need for more storage space.

There are many factors that affect what kind of surveillance storage solutions can and should be implemented at a facility. The size of the project, existing infrastructure, and client budget are all critical determinants as to what type of storage should be implemented. The camera type, camera quantity, compression standards, frame rates, motion detection, desired length of storage, and overall estimate of desired resolution all should be taken into account as well.

When it comes to storing surveillance data it is paramount that the integrity of the footage is not lost. Traditionally surveillance footage would be stored on a DVR (digital video recorder), but it’s limitations within a networked system make it less than ideal. With so much of the surveillance world developing around IP and network solutions it’s only natural that network storage solutions should arise. NAS (network attached storage), SAN (storage area network), and DAS (direct attached storage) are all potential methods for storing surveillance data. All have different installation requirements. Some may call for extensive cabling and a large closet to store servers, but it all depends on the size and type of project. According to Justin Schorn, vice president of product management for Aimetis, “The critical decision is choosing between a storage area networks (SAN) and network attached storage (NAS).”

The different storage devices vary in how they present information to the user and how data is accessed. The NAS devices present data in a “file system” same with DAS, whereas SAN is presented in what is referred to as “block storage.” DAS and NAS either attach directly to an existing network or the NVR (network video recorder). SAN is essentially an extension of a DAS, but provides a higher storage capacity.

DAS is typically implemented in situations when expansion is not an option, the system performance requisites are static, and shared access is not necessary. The reason being is DAS devices are limited to singular DVR or NVR applications. SAN solutions are typically used in larger camera applications that may later require scalable options. According to Lee Caswell, founder and chief marketing officer at Pivot3, “Many archivers can share the storage and the SAN platform introduces more reliability over NVR/DVR systems because there is no single point of failure.” Common applications for SAN storage include airports, casinos, and prisons.

NAS devices are typically used in smaller surveillance applications as its performance isn’t as robust as SAN. One of the advantages to NAS solutions is data can be easily accessed by anyone on the same protected network. Lee says, “The advantage of the file system on the NAS platform is that it is easier to support a hybrid storage case as some storage occurs locally on self-contained NVRs/DVRs and extended storage is sent to a specific file on the NAS.”

Keeping high quality recorded data for longer periods of time can help local authorities with investigations and it can provide insight into your business that you otherwise wouldn’t observe. While storing recorded footage from your surveillance system is critical to your overall security, it’s important to remember that the type of storage necessary will vary depending on the project parameters. It is imperative to work with a licensed security system integrator to help evaluate security risks, the quantity of cameras needed, and how a surveillance storage system can be implemented to meet your requirements. At Perfect Connections, Inc. we are committed to providing security systems that suit your specific needs. We have been designing and installing comprehensive security systems at businesses throughout northern and central New Jersey since 1992.
