CCTV surveillance systems have made enormous technical advancement in the previous decade, not just in terms of individual capabilities, but also in terms of their capacity to connect with other security equipment.
However, CCTV monitoring systems are now so prevalent that their novelty has worn off, diminishing their usefulness as a simple deterrent, particularly for unauthorized entry or violent crime.
CCTV Surveillance Systems’ Changing Applications
CCTV surveillance systems have grown into a forensic tool, collecting evidence after an event has occurred, as recording and storage technology and software such as video analytics have become more efficient.
However, as CCTV surveillance systems become more easily integrated with monitoring devices, alarm systems, and access control devices, a third application of CCTV is gaining traction: assisting security personnel in detecting and interrupting security breaches as they occur, or even before they occur.
Intelligent video algorithms, such as advanced motion detection, may detect strange walking patterns and warn a guard to keep an eye on a specific video screen.
Facial recognition is the most advanced intelligent video algorithm. Most experts concur, however, that the adoption of this technology as an efficient tool in the commercial sector is still some years away.
Traditionally, intelligent video algorithms are components of a computer system in a security room that receives footage from a network of CCTV cameras. However, manufacturers are working on cameras that will be able to process the intelligent video algorithm right inside the camera.
Another feature that is becoming more common on CCTV cameras is wide dynamic range. Cameras with a high dynamic range can discern details even when there is a lot of light and dark in the same picture. Traditional cameras are incapable of doing so.
