The Matrox Monarch HD is an HDMI input/output streaming and recording device that can stream live events and record master versions for post-production or storage at the same time. The streaming and recording functions are totally independent of each other, and therefore recording quality is not affected by streaming bandwidth, and record controls can be operated without disturbing streaming operations. Recorded files are available anytime during a streaming session for use as complementary streaming videos.

Monarch HD generates RTSP/RTMP compliant H.264 streams from any HDMI source using a built-in encoder and multi-tap 10-bit scaler and de-interlacer. It records the live streams as H.264 MP4 files with two channels of embedded AAC audio to an optional SD card, USB drive, or network-mapped drive. Network-mapped drives are useful if multiple users will need to access the recorded footage. Streaming bitrates can be assigned at up to 20Mbps and recording bitrates at up to 30Mbps. You can stream to your own server or to CDNs like YouTube.

Bitrates, resolution, and other operational details are selectable in a web-application called Command Center. Via an Ethernet connection from Monarch HD to a router, Command Center is accessible on a phone, tablet, or computer. Up to four Monarch HD units can be controlled from Command Center simultaneously. Stream and record start/stop can also be controlled via push buttons on the front panel.

Monarch HD operates on a Linux O/S and isn't vulnerable to any automatic updates or unscheduled exchanges with 3rd party servers.
