The Hollyland Syscom 421S 4-Transmitter 1800' A/V Transmission System is a four-camera multi-cam wireless video transmission system that can daisy-chain up to four cameras with one receiver with PTZ control and tally. Supporting 1080p60 video signals, it sends and receives your video via SDI and HDMI. The link has a maximum transmission distance of 1800' (line-of-sight) with less than 0.07 second latency. Ethernet pass-through over the transmitter/receiver allows for direct streaming to the Internet via RTSP with the Hollyland Syscom 421S 4-Transmitter 1800' A/V Transmission System.

The receiver features four SDI and four HDMI outputs (one for each transmitter) for connecting to a monitor or switcher. You can control PTZ cameras via IP or RS-422/485 serial connections. The transmitters have a dedicated tally output port that support optional tally lights. Both units also have an OLED display that confirms the resolution, transmission channel, signal strength, and other details such as battery power. Each transmitter has an L-series battery plate, and the receiver has a V-mount battery plate. Both Transmitters and receivers also feature a 2-pin power input for alternate DC power options.
