The millennial age has seen the evolution of CCTV cameras and its increasing usefulness for various security needs. CCTV was first known to have been used in Germany in 1942. At the time, cameras were only used to observe rocket testing. Back in the days, the only two components of the security system were cameras and monitors. During its inception years, the surveillance camera was only used for live monitoring, which remains its fundamental use even today.

Here are some interesting details on the evolution of surveillance cameras.

VCR-Based Systems

When they first arrived, CCTV cameras used to be connected to VCR to record video. The VCR had cassettes, which would record videos from the CCTV camera. One tape lasted only eight hours during the VCR days. These used to function well; however, scalability was an issue. The need to maintain tapes and VCRs was another concern, which led to further developments.

DVR-Based Systems

The digital revolution in the CCTV camera industry began in the 1990s. The video was digitized and also compressed to store higher number and hours of recordings. Since the DVR had limited space, the recordings were also limited. However, it helped in doing away with large tapes and tape recordings. The quality offered by DVR was much more consistent as compared to its predecessor. It also allowed for a quick search within the recorded video.

Network Video Systems

Today, DVR and VCR have been replaced by much more advanced technology of network-based video systems. Cameras now come with IP network connection. Images that are recorded on cameras are digitized and remain in the system for as long as the user wants. These are high-quality images, which can assist better when it comes to thorough monitoring. Some of the cameras even allow for backdoor password set-up, thereby reducing the chances of a potential hack.

Surveillance for All

CCTV cameras are no longer for the privileged and formal settings alone. A number of people today can afford these cameras and thereby ensure their own and their family’s security. With smart CCTV cameras, the data provides high-resolution images and recordings along with audio, which can be used for multiple security measures.

How will the surveillance cameras evolve further? Only time can answer this question. But, it is the security measures, which will continue to be enhanced with newer technological introductions in the surveillance systems. Be it drones, HD imagines, or artificial intelligence, CCTV cameras are getting merged and integrated within systems to provide end to end security.
