Closed Circuit Televisions or CCTVs as we call them lovingly are present everywhere. From railway stations, metro compartments, supermarkets, and even in your favorite restaurant where you go for a nice dinner with your friends and family. Remember George Orwell’s famous novel‘1984’, where he predicted the future filled with surveillance. That future is here, for better or for worse but we are under constant watch of authorities and cameras.
The use of these cameras whether right or wrong has been under debate for long and still is. This will continue till the human mind has its argumentative ability to think which we have developed over the course of our evolution. Some feel the CCTVs surveillance provides a sense of security and it has helped in reduction of crime, while the opposing camp feels this is in violation of privacy of lives. I am not giving my mind here and will not declare my point of view as it is the topic of discussion some other time and we will stick to the topic of CCTV footage recovery from damaged or deleted CCTV DVR footage.
If you have somehow deleted your video footage from CCTV DVR or your DVR hard disk is damaged even physically, it is not the end of the world.

Understanding CCTV, DVR, and CCTV DVR
As the Wikipedia page of Closed circuit television says:
Closed-circuit television (CCTV), also known as video surveillance, is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors.
The ‘closed circuit’ in the name comes as the cameras are providing feed to monitors, DVRs on a private coaxial cable or wireless communication links, and the system is designed as such the content is accessible to authorized personnel only. To say simply it is just another TV system but where the signals are not for open public transmission like that on broadcast television, instead the signals from CCTV is used to be transmitted to a predefined place and on specifics set of monitors. CCTV may use point-to-point (P2P), point-to-multipoint (P2MP) or mesh wireless networks.
CCTV systems have evolved over the period of time, earlier CCTV systems used to have low-resolution black and white monitors which did not have any interactive support. As the technology has improved modern day CCTV systems use color monitors with high-resolution with the ability to zoom in, track something, also there is Talk CCTV which allows the observer to speak to people in the range of camera speakers.
For CCTVs to work accurately, the placement of the cameras is an important point of consideration as it is the starting point of your surveillance. If the camera placement is not right then and if some of the areas which need to be covered in the surveillance are left out then the whole exercise goes for a toss.
CCTVs can be used for various purposes, some day to day uses where we see these cameras in function are:
- Traffic monitoring.
- Monitoring for security at busy transit spots like train stations, airports.
- Metro compartments.
- Banks and other financial institutions.
- Shopping complex like supermarkets and malls against theft protection
- For security in buildings and underground parking.
These are some examples use cases for CCTVs are increasing day by day and the need and for the systems to be running is also up in the market.
