H.264 PoE Video Encoder
IP SURVEILLANCE
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.
What is a Video Encoder?
Video encoders, also known as video servers, enable an existing analogue CCTV video
surveillance system to be integrated with a network video system. Video encoders play an
important role in installations where many analogue cameras are to be maintained.
A video encoder makes it possible for an analogue CCTV system to migrate to a network video
system. It provides the benefits of network video without having to discard existing analogue
equipment such as analogue CCTV cameras and coaxial cabling.
How does it work?
A video encoder connects to an analogue video camera via a coaxial cable and converts
analogue video signals into digital video streams that are then sent over a wired or wireless
IP-based network (e.g. LAN, WLAN or Internet). To view and/or record the digital video,
computer monitors and PCs can be used instead of DVRs or VCRs and analogue monitors.
By using video encoders, analogue video cameras of all types, such as fixed, indoor/outdoor,
dome, pan/tilt/zoom, and other specialist cameras can be remotely accessed and controlled
over an IP network.
What are the benefits of a Video Encoder?
A video encoder also offers other benefits such as event management and advanced video
and security functionalities. In addition, it provides scalability and ease of integration with other
security systems.
