Ultra Low Latency 8-channel Video Streaming Appliance

The microHydra-SD8 is a 8-channel Ultra Low Latency (ULL) IP video streaming appliance, capable of capturing, compressing and concurrently streaming up to 8 channels of NTSC/PAL/RS-170 video with a latency of under 40ms. This rugged video appliance is ideal for rapid deployment in demanding applications in Military, Communications, Transportation and Energy industries.

The microHydra-SD8 features a dedicated hardware H.264 compression engine that can encode all 8 video channels at full size and frame-rate. The flexible RTSP/RTP streaming engine supports Unicast and Multicast and streams each channel over the GigE Ethernet to client systems for low latency viewing and analysis. The microHyrda-SD8 also supports 4 channels of audio which can be captured and streamed with the video data.

The microHydra-SD8 has a vehicle class power supply and can be driven from a 12-28V DC input. The system is housed in a rugged, watertight, conduction cooled, IP67 rated enclosure with sealed MIL-D38999 connectors and is ready to be installed into mobile platforms and harsh environments.

Ultra Low Latency (ULL) Streaming

Less than 40ms video encode latency (1)

(1) Streaming latency is less then 40ms. When audio is included in the stream, overall system Glass-to-Glass streaming latency can be higher due to audio buffering at the remote client.
