Video Surveillance System (cctv)

Video surveillance is the use of security cameras to monitor and record activity in a specific area or location for security, safety or monitoring purposes. Security cameras capture live footage, which can be viewed in real-time or recorded for later review.

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.

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 if using an IP camera and system (more on that in a moment) 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.

Video surveillance systems are closed - this means its signals are not broadcast so that others could intercept and view the content. Only authorized users can access the recorded material.
