A closed circuit television system is comprised of three basic components. A camera to capture the analog or digital image, a switching or recording device to route or store the image and a monitor to view the image. Closed circuit television is currently the fastest growing and most popular technology in our market today. With the advent of digital video recorders, digital TCP/IP cameras and power over Ethernet an end user is now able to install a complete system over their existing CAT5 infrastructure saving potentially thousand of dollars in redundant wiring. Cameras are available in a variety of styles and functions to include: fixed, dome, interior, exterior, vandal resistant, pan-tilt-zoom and day/night. The mass storage device; however, is undoubtedly the most important component of the system. Without an adequate and dependable recorder, images may be lost without the ability of retrieval. Currently the most reliable DVR’S are Linux based and include native Web Servers for remote viewing of the video feed.
