D-Link’s high-performance, single channel video encoder integrates an existing analogue CCTV (closed circuit television) into an IP-based video surveillance system. These video encoders are the ideal choice for businesses where surveillance equipment is already installed and functioning. The alarm handling features provide alerts in the event of loss of video or loss of network connection. Motion alarms with configurable detection areas allow for effective surveillance and help to mitigate the need for constant human supervision. A buffer system allows the server to capture images to the built-in SD card slot both before and after an event occurs.
