What is HD Video Surveillance?
A video surveillance system / CCTV is composed of a system of cameras, monitors/display units, and recorders. Cameras may be either analog or digital with a host of possible design features.
These systems can be applied to both interior and exterior areas of a building or property. They can operate 24/7, can be designed to only record in response to movement, or set to record during specific times of the day. Today, cameras can be equipped with SMART Analytics, which can enable the camera to watch for different events to happen. Just as if a live person was watching.
The cameras may be conspicuous and out in the open to deter crime, or they can be more hidden and discreet to record evidence with fewer chances of being tampered with. Footage can be monitored live by a security guard, monitored remotely by a monitoring company, or can simply be recorded and stored by a DVR (digital video recorder) or NVR (network video recorder) for review later should the need arise.
