Closed Circuit Television (CCTV) also known as video surveillance. In this technology, video cameras, computer monitors or led television, hard disks, recording devices are used by connecting them together. This technology is used to monitor sensitive areas (areas where crime is high and no human security is available).
CCTV displays all the activities in its range on the monitor screen and records them. Therefore it is very helpful in preventing crime as it is also used to monitor traffic by detecting congestion and accident.
Signals received from the camera and mic are secured to the hard disk via a cable or wireless recording device. The quality of audio and video signal received from these cameras is very good. These cameras record the video in high definition even at night, but the night video is black and white.
