Trying to understand how a video surveillance system works can often lead to a person scratching their head in confusion. It may seem complicated at first, but learning how it all works is not really that hard.
People only need to get acquainted with some of the more important facets of surveillance systems to learn how they really work. Here are some of the more vital points in understanding how these surveillance systems operate.
Placement and Number of Cameras
Most people have no idea how many cameras their place needs or where to put them. Choosing the right number of cameras and knowing where to put them is not difficult to learn, but it does take a lot of effort.
The first step is to make a layout or blueprint of the location. The layout makes it easier to highlight the different entry points, the amount of space that needs video surveillance coverage, the best angles for camera placement and so much more.
The number of cameras is primarily influenced by the amount of space that needs surveillance. The bigger the perimeter the more cameras the system will need to keep track of any activity in the area. The number of cameras can be reduced by the use of PTZ cameras. PTZ stands for pan, tilt and zoom. A single PTZ camera may be capable of covering an area that would have required several static cameras.
Placement is determined by the viewing angle. Security cameras are often located in places that provide maximum coverage. This is the best way to get the most out of a single camera.
Keeping Things Connected
Todays video surveillance system can be networked either through wires or a wireless system. Either type has its advantages and disadvantages.
The advantage with most wired surveillance systems is that they are tried and tested. This is a form of technology that most security systems are already familiar with. The downside is that they can be difficult to install. Depending on the size of the location and structure, some form of renovation might be necessary to let the wires run through the home or building. This could prove more costly than anticipated.
The advantage of wireless systems is that they do not require the kind of renovation that wired systems need in order to accommodate them. This makes them cheaper to install. The downside is that some wireless systems can be a bit buggy. Remember that wireless systems rely heavily on information technology, which is the same kind of technology that powers Wi-Fi routers. Failures or anomalies in a wireless video surveillance system can be more difficult to troubleshoot than the problems a person are likely to encounter with a wired system.
