Closed-circuit television (CCTV) surveillance systems have made tremendous technological progress in the last decade, not only in terms of individual capabilities but also in terms of their ability to interface with other security technology.
According to industry experts, there are three primary uses for CCTV systems: as a deterrent, for forensic purposes, and as an interdictive device.
Initially, CCTV surveillance systems were merely a deterrent. The fear that someone was watching was often enough to keep people from misbehaving. However, CCTV surveillance systems are now so common that they have lost their novelty, reducing their effectiveness as a simple deterrent, particularly for illegal entry or violent crime.
CCTV installation Adelaide City is Changing. CCTV surveillance systems have evolved into forensic tools, which collect evidence after an incident has occurred.
However, as CCTV surveillance systems become more easily integrated with monitoring devices, alarm systems, and access control devices, the third application of CCTV is gaining attraction: assisting security personnel in detecting and interrupting security breaches as they occur, or even before they occur.
Intelligent video algorithms, such as sophisticated motion detection, can detect unusual walking patterns and alert a guard to keep an eye on a specific video screen. Object-recognition algorithms can detect people who are simply loitering, as well as a briefcase NBN Cabling Installation Adelaide or other suspicious objects that have been left somewhere they should not be. Again, the system can notify a monitoring guard to take appropriate action.
Facial recognition is the most advanced intelligent video algorithm. Most experts agree, however, that the use of this technology as an efficient tool in the private sector is still several years away.
Traditionally, intelligent video algorithms are components of a computer system in an NBN Cabling Installation Adelaide that receives video from a network of CCTV cameras. However, manufacturers are working on cameras that can process the intelligent video algorithm right inside the camera.
Another technology that is becoming more common in Security Camera Installation Adelaide is the wide dynamic range. Cameras with a high dynamic range can resolve details even when there is a lot of light and dark in the same scene. Traditional cameras are incapable of doing so.
