When they were first introduced, video surveillance systems were mostly used with medium to large businesses. These days however, they are becoming more and more common in homes. Video surveillance security systems are also known as Closed Circuit TV (CCTV) and are used to monitor certain areas around the home and help to protect it from burglars and thieves.
The monitor is a key aspect to the video surveillance setup. The monitor will feed the video from the cameras that make up the system. The monitors are normally black and white and feature a higher resolution than that of a standard television set. Monitors vary in size and resolution, although the standard resolution is between 500 and 1000 lines.
