The name CCTV stands from Closed Circuit Television, as opposed to broadcast television, which has a bigger area of effect and a broader point. CCTV basically transmits a live feed from a camera (or a set of cameras) to a distinct network of terminals, whereas broadcast TV transmits the signals loosely.

All the way through the last century, CCTV has become more and more useful as a instrument for security and monitoring. The first CCTV systems were used in the military, as a means of monitoring several simultaneous rocked launches. However, since then, the system has been picked up by the security industry and its use in institutions, large private areas, malls, entertainment or luxury resorts and even in homes, increased with each passing year. The technology used for this system advanced equally fast as the number of users, which gave birth to a new idea: wireless.

Wireless CCTV can be used, for the most part, in any circumstance that a normal CCTV would be used, but with the understandable advantages in installation and maintenance costs.

A straightforward example where wireless greatly surpasses the excellence and performance of traditional CCTV is using it with moving trains. Wireless CCTV is quickly gaining approval as the security or monitoring measure of choice in such environments.

Another wireless CCTV technique that gains more and more popularity is the spy cam area. Evidently, when hearing the term spy cam we think of something that belongs either to someone starring in an action James-Bond type of movie or to someone that will use it for some ill-behaved purposes.

Although it might be true that the enhanced concealment capability of such wireless CCTV spy cams can be used for such purposes, they are becoming crucial in crime monitoring, crime prevention and so forth. A few simply examples could include hidden wireless cams to keep an eye on crime in areas such as metro stations, banks, stores or institutions.

There is a definite debate going around as to whether or not wireless cams will prove to be efficient in sinking crime or not, since a number of people believe that the fact that the camera is actually visible is a reason that reduces the chance of a crime happening.

Still, in spite of the obvious benefits of wireless CCTV cameras, theres still a streak of disagreement that surrounds the subject, especially when it comes to using them in public areas. Taking regular screenshots and performing ID checks on people under surveillance in public areas is considered by many an attack to ones privacy.

Another hefty group of people recognize this as an acceptable restriction to privacy, if the system proves successful in revealing terrorists, car thieves, murderers or other criminals in time. Regardless of which side one takes, several governments already took a firm position about the use of wireless cameras in the future, as part of national security and protection programs.
