The Syscom 421S 4-Transmitter 1800' A/V Transmission System with Carry Case from Hollyland is a multi-cam wireless video transmission system that communicates with up to four cameras using a single receiver with PTZ control as well as tally. Supporting up to 1080p60 video signals via SDI and HDMI, the transmitter/receiver system offers an 1800' line-of-sight transmission range with 0.07 second latency. The 421S system also supports Ethernet pass-through, so you can stream directly via RTSP to the Internet.
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 receiver also feature a 2-pin power input for alternate DC power options.
