The XStream-SD4 is an intelligent, stand-alone, ultra low latency H.264 Streaming solution that accepts 4x NTSC/PAL/RS-170 composite video sources and records and streams them over 100/1000MBit Ethernet. This SWaP optimised solution is ideal for rapid deployment in demanding applications in Military, Communications, Transportation, Mining and Energy industries.

The XStream-SD4 features a dedicated hardware compression engine capable of encoding all 4 video channels at full size and full frame-rate with Ultra Low Latency (under 40ms). The flexible streaming engine can stream each channel direct from the on-board Ethernet port as well as save direct to locally attached storage for later retrieval. The XStream-SD4 also supports 4 channels of audio that can be captured and streamed with the video data.

The XStream-SD4 is an intelligent stand-alone device with its own on-board CPU and does not require a host CPU or any driver or OS software. For mechanical convenience the module can be mounted on a PC/104 stack without consuming host CPU resources.
