SURVEILLANCE CAMERA BASICS

More and more people are adding surveillance cameras to their home and businesses. They have always been good for security but people are now catching on that they are a great management tool as well. Prices today are surprisingly affordable and the types of systems and features vary greatly.

First let’s talk about the two basic types of cameras available. Analog and IP. Analog cameras are the older technology and require a monitor or TV to view them and are recorded on a digital video recorder (DVR). They are also limited to the same standard resolution you see on your TV set. In order to remotely view analog cameras, your DVR would have to be connected to the internet and you would log into the DVR and see the cameras through it.  You could also see what the DVR recorded.

IP Cameras transmit their signal in the same manner that computers do and their resolution is not limited like analog cameras are. That said there are IP cameras that transmit the signal via IP but are standard resolution cameras. IP cameras go up to 10 megapixel and can give a superb High Definition picture. IP cameras do not need a recorder to be viewed. You can log into each camera directly and if you do not want recording capability, that is all you need. Taking that a step further is cloud recording. Whenever the camera detects motion in front of it, the scene is recorded in the cloud for viewing at a later time. You can also receive text messages and/or emails informing you that the camera detected motion and you can even receive via email the video clip that was recorded. For cloud recording there is a monthly charge, starting around $10 per month depending on how many cameras and how much storage space you will require.

IP cameras can also be recorded locally, on a Network Video Recorder.  This device can be reached remotely from anywhere in the world and you can watch your cameras live or see what they recorded.

Having recording capabilities on site is a plus because if your internet is down, the cameras can’t transmit to the cloud recorder. To solve this problem, many people install a network recording appliance that will record all the video from the cameras for later access while still giving you the convenience of cloud service.

All these camera types come in indoor and outdoor models. IP cameras can even come in 360, where one camera mounted on the ceiling will cover the entire room.

With video surveillance today, you can watch your home or business from anywhere in the world on your computer, smart phone, or tablet. All you need is an internet connection.

Can Surveillance Cameras Really Help Catch Criminals?

We have all seen the TV shows.   A crime of some kind occurs and from some office some law enforcement agency logs on to every surveillance system in the area, and they all have high quality video, and in a matter or minutes identifies the criminal that committed the act.

Well, reality is quite different. Here is what usually happens. The police look around and see if any of the buildings in the vicinity have surveillance systems.  They then contact the building owner and ask them for the footage from a specific time. They then look at the footage and determine whether the cameras saw the event. If so they have to determine if the quality is high enough to ensure an identification. Often times, it isn’t.

If the footage is decent, there are some techniques and software available to improve the quality, but no where near the scope that TV shows make you believe.  You can’t take a fuzzy image of a car and end up with a sharp picture of the license plate.

The quality of the surveillance system has a lot to do with this. Many analog systems just don’t have the lines of resolution to produce a sharp, clear picture. Over time, the camera loses focus and the overall picture quality can deteriorate.

The new IP systems, with megapixel cameras, can greatly improve this but focus is can still be an issue. It is also very important that all settings are correct, like motion detection and white balance, so you get the image you need.

Below the image on the left is analog and the image on the right is a 1.2 megapixel camera.

The difference is striking.

So the answer is yes, surveillance cameras do help catch criminals.  But, it requires a lot of legwork to get the job done. Megapixel cameras are helping to up the odds of capture.
