CCTV camera was first developed by the German man named Walter Bruch. The first CCTV camera was used to watch the launching of rockets carefully. In CCTV the signals are not openly transmitted, though it may employ point to point, point to multi-point or mesh wired links of communication.
In early days video surveillance involved constant monitoring as there was no way to record and store information. With the commencement of reel to reel media the recording of surveillance footage has become possible. But again these systems required changing of the magnetic tapes manually. When digital multiplexing was developed, it allowed several cameras to record at once. This led to increased savings of time and money which then led to an increase in the use of CCTV.
- CCTV has extensively spread its application in surveillance.
- Surveillance of public areas, banks, police stations, crime-prone areas uses CCTV in many areas of the world.
- In industrial areas CCTVs are used to monitor the functioning and parts of the process of the control room.

A growing branch in CCTV is internet protocol cameras also known as IP cameras, which outsold the analog cameras. It is mostly used by the LANs to transmit the video signals across the data networks in digital networks. Again many consumers are turning to wireless cameras.
CCTV cameras are effective at deterring and solving the crime and appropriate regulation on the surveillance of public spaces can provide protection such that an individual’s right to privacy can reasonably be compared against the benefits of surveillance.
However anti-surveillance activists have pointed out the right to privacy in public areas. Furthermore, there may be scenarios wherein a person’s right to public privacy can be both reasonably and justifiably compromised.
