The Samsung 1 Channel H.264 Network Video Encoder encodes a single channel of analog video and audio for transmission over a network. Along with converting A/V signals, this unit will digitize the PTZ control signals of a dome camera connected to its RS-485 control port. Multi protocol PTZ support enables interoperability with third party CCTV controllers and DVRs.Video is encoded using the H.264 compression format at up to 30 fps at 4CIF resolution, ensuring quality video images while maximizing bandwidth usage. Video can be simultaneously streamed to multiple destinations, with each stream individually adjustable for frame rates and resolution to suit different security and network requirements. MJPEG and MPEG-4 compression methods are also supported for greater versatility. Conformance to the ONVIF (Open Network Video Interface Forum) protocol standard enables easy integration with third party network video products.This encoder features RCA audio in and out connectors, which when used with an appropriate mic and speaker will allow 2-way voice communication over the network.This encoder features an on-board SD/SDHC card slot which can be used for local storage and as a means of backup in case of a network failure. There are also alarm I/O ports for interfacing this encoder with an external alarm and relay device. Alarms alerts can also be triggered by the encoder's built-in motion and video loss detector. With the addition of a PoE midspan, this encoder can be powered via its Ethernet cable. By eliminating the need to run a separate power cable to the camera, PoE saves time and installation costs.
