CCTV, or closed-circuit television, is a system that allows you to keep an eye on what’s going on in and around your business. Cameras and monitors enable you to view events live, and recorders archive footage for later reference.
Don’t mistake a CCTV monitor for an ordinary television. It doesn’t receive publicly broadcasted content—only footage from security cameras installed on the premises.In order to see at night, most CCTV cameras use infrared (IR) technology. These emit infrared light at night, which allows the camera to see even in total darkness. Infrared light is invisible to the human eye, which is why burglars cannot see that the CCTV camera is activated.
CCTV technology has been around for decades, but improvements in recent years make it even more effective at capturing criminals in the act and bringing them to justice. Consider the various parts of a CCTV system and how they all work together.
How do CCTV systems work? A CCTV system consists of a camera, lens, monitor and recorder. The camera/cameras pick up the images, which are then transmitted then to a recording device and then a monitor.
