Video security systems can be used for security, remote monitoring of dangerous areas (often found in mining operations), or analysis of shopping patterns within a store. A video surveillance system is comprised of two primary components: a camera for capturing video and a recorder for recording the video. Other components such as camera lenses, camera housings, infrared illuminators, and wireless transmitter/receivers help create a system designed for your exact needs.A recent trend in video surveillance is the popularity of network or IP video cameras. Network/IP cameras capture images digitally and transmit video using standard Internet protocols. Network/IP video security systems are easier to install, have more features, and can be monitored or configured from anywhere in the world.
