Aprašymas

The Syscom 421S sends synchronized audio and video from up to four transmitters to a single receiver on the same RF channel, working in the 5.1–5.9GHz band with 40MHz bandwidth. Stated range is up to 1,800ft (550m) with 0.07s transmission latency, and video formats run up to 1080p60.

Each transmitter takes one SDI and one HDMI input. The receiver provides four SDI and four HDMI outputs, so every camera feed can be routed to separate destinations. Tally output is supported for multi-camera setups.

RS485/RS422 ports allow control of PTZ cameras and switchers, and a LAN port provides wired network connection, including Ethernet passthrough between the receiver and each transmitter and RTSP streaming. Up to four systems (16 transmitters in total) can operate at the same time. It is sold as a 4TX + 1RX or a 2TX + 1RX package.
