Digital to analog video decoder

The Moxa VPort D351 is a single-channel industrial video decoder that can decode MJPEG and MPEG-4 network video and audio streams from video encoders and IP cameras and then send the analog signals back to traditional CCTV equipment.

The decoder links standard analog CCTV devices such as monitors, multiplexers and matrix switches used in surveillance applications to an IP-based video surveillance network. Additionally, a bidirectional audio function enables real-time voice-over-IP communication between a video encoder and decoder, while a transparent PTZ control allows instant control of remote PTZ controllers at the control site.

The device can continuously monitor and track events from analog CCTV systems by switching between up to 64 different video sources. The video streams can be selected manually by web server, or automatically by scanning within a set time interval.

The device provides the ability to synchronise the control of remote PTZ cameras from the control centre, without having to install a separate driver for each PTZ camera. It enables users to handle remote PTZ control through a web interface, and adjust the direction and zoom setting of the camera.
