Why CCTV is called Closed Circuit Television?
The video that is recorded by a CCTV camera is shown on some limited display device already defined or recorded on a limited recording device
This recorded signal is not publicly broadcasted, meaning a closed group or limited people has access to the recording of a CCTV camera.
For this reason, CCTV is called closed-circuit television.
History of CCTV
CCTV was launched in 1942 by German engineer Walter Bruch to watch the launch of the V2 rocket Privately from his home.
Initially, when CCTV was made, it was only able to record black and white video, but today the field of CCTV has grown a lot.
Today we can record high-definition video from CCTV and can access it from anywhere through the Internet.
Recorded videos can be zoomed through today’s high-tech CCTV, and can accurately identify a person or vehicle.
Even today CCTV has come up with a Face Recognition facility, which can identify a particular person and inform the authority, without the help of any human being.
High-tech, high-definition cameras mounted on traffic signals also keep a close eye on vehicles and drivers,
Even these cameras record the number and speed of the vehicles, and if there are any speed violations, then send the information to the system, with recording proof.
