About: Hollyland Syscom 421S Transmission System

The Hollyland Syscom 421S 4-Transmitter 1800' A/V Transmission System with Carry Case is a multi-camera wireless video transmission system that communicates with up to four cameras via a single receiver with PTZ control and tally. The transmitter/receiver system, which supports up to 1080p60 video signals via SDI and HDMI, has an 1800' line-of-sight transmission range and 0.07 second latency. The 421S system also supports Ethernet pass-through, so you can stream directly to the Internet via RTSP.

The receiver has four SDI and four HDMI outputs (one for each transmitter) for connecting to a monitor or switcher. PTZ cameras can be controlled using IP or RS-422/485 serial connections. The transmitters have a dedicated tally output port that supports 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, while the receiver has a V-mount battery plate. Both the transmitter and receiver have a 2-pin power input for alternate DC power options.
