Hollyland Syscom 421 Wireless Video and Audio Transmission System
The Hollyland Syscom 421 Wireless Video & Audio Transmission System 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 a tally. Supporting up to 1080p60 video signals via SDI and HDMI, the transmitter/receiver system offers a 548m line of sight transmission range with 0.07-second latency.
The receiver features 4 x SDI/HDMI outputs (one for each transmitter) for connecting to a monitor or switcher. You can also connect the receiver to a LAN, allowing you to pass control signals from a control panel to the transmitters. This enables you to control PTZ cameras as well as send tally information. The transmitters have a dedicated tally output port. Both units also have an OLED display that confirms the resolution, transmission channel, signal strength, and other details such as battery power. The transmitters each have a built-in L-series battery plate, and the receiver has a V-mount battery plate. Both Transmitter and receiver feature a 2-pin power input for extended run times.
