Closed Circuit Television (CCTV) is a system where the circuit in which the video is transmitted is closed and all the elements (camera, display monitors, recording devices) are directly connected. This is unlike broadcast television where any receiver that is correctly tuned can pick up and display or store the signal. Such specialized systems are not subject to regulation by the Federal Communications Commission (FCC); however, security cameras using scrambled radio waves are in fact subject to common carrier tariffs and FCC conditions of service. In the past, these signals would be transmitted to a monitor equipped with a videocassette recorder, but these have been all but totally replaced by digital video recorder (DVR) systems that can store far more video and back up data automatically.
The demand for security and surveillance equipment is on the rise in India in all the verticals, given the increasing awareness among customers about security. The Indian market for network cameras is growing swiftly, as the enterprises, small and medium businesses and end customers are looking at surveillance technologies as a prime necessity.
The consumption of security products in the residential segment is also increasing rapidly.
