Contemporary scientific advancements have reached un-scalable heights. Reality of this time has touched the imagination of the past. Things which people only used to fantasize and hallucinate about have turned into hard core happening reality. Sheer fancy and artistic illusions have ceased to become illusions any more. Especially, the process of computerization proved to be a severe boon for the entire human race. With the invention of the technique of digitization the existing periphery between the world of reality and the virtual was firmly delimited once again. This is something that is better described as the transitional phase to mark two separate ages. Human life before advent of the cyber age was a certain entity. The same in this present cyber age is a complete different entity. The two are so drastically apart from each other, that is hard to imagine. Communication has become so easy in all aspects these days. The distance of geography is no more a problem, thanks to the virtual world. Trans-continental communication hardly a few decades back implied crossing over the oceans and continents of the world to reach one point from another. It was both time consuming as well as expensive. The cyber age has resolved all such related constraints and many more. Today, audio-video feeds send from a spacecraft clearly shows the cosmic changes happening in the outer space. This technology has proved to be equally helpful in introducing us to surveillance camera system to boost our personal safety and security in this changed atmosphere. This new-age security system involves video cameras to transmit audio-video signals to a desired location, generally on remotely placed monitors. For this reason, the security system is also known as video surveillance systems.

The modern security system has manifold advantages. These are very common in markets all over the world. The gadgets involved in this are quite simple to install, use and control. Cameras are available in all possible shapes and dimensions. This makes it possible to install them at the most vantage points and locations. Powerful lenses inside these cameras are indifferent to extreme weather conditions. Most of these are as well capable to capture videos in low light conditions. Surveillance camera system that is available these days are almost free of buses and cords. This makes the installation process easy and the entire place remains clutter free. These are very reasonably priced which makes it easily affordable in all homes. Particularly in places like ATMs, parking lots, banks, casinos etc. this system proves very helpful. Sensitive security zones like airports and various government and military establishments require these modern video surveillance systems perhaps more than anywhere else. In factories and in large industrial manufacturing houses, this surveillance system has its utility too. There it can be used to monitor a part of a procedure where the environment is hazardous for human existence. The biggest advantage that it offers is the elimination of human involvement in the surveillance process, thus resulting in massive cost cutting in the entire process. The gadget has gained considerable domestic acceptance and is common in many homes too.
