Cameras are sold separately. Using MJPEG compression, the 14-Inch Monitor w/Built-In 4-Channel 80GB DVR can record 4 channels at 7.5 fps per channel. View playback on a quad display on the monitor, which also shows the date and time. Schedule recording at specific times or record manually, using the buttons on the monitor's front panel. The 14-Inch Monitor w/Built-In 4-Channel 80GB DVR works with four of your existing surveillance cameras.
