Hollyland Syscom 421 2-Transmitter 1800' A/V Transmission System

The Hollyland Syscom 421 2-Transmitter A/V Transmission System is a professional multi-camera wireless video solution designed for broadcast, live events, and multi-cam production workflows. It enables simultaneous transmission from multiple cameras to a single receiver, streamlining monitoring and switching operations.

Operating on a powerful 5 GHz wireless system, the Syscom 421 delivers stable transmission with an impressive range of up to 1800 ft (550 m) line-of-sight and ultra-low latency of approximately 0.07 seconds, ensuring near real-time video monitoring.

The system supports Full HD 1080p60 video via both SDI and HDMI interfaces, making it compatible with a wide range of professional cameras and production equipment. Each transmitter sends synchronized audio and video signals to the receiver, allowing seamless multi-camera coordination.

Designed for advanced production environments, the Syscom 421 supports PTZ camera control and tally functionality via LAN, RS-422, and RS-485 connections. This enables operators to manage camera movement, shading, and live status indicators remotely for efficient production control.

The receiver features multiple SDI and HDMI outputs—one for each transmitter—allowing direct connection to monitors, switchers, or broadcast systems. With support for Ethernet pass-through and RTSP streaming, it can also integrate into IP-based production workflows.

Built for reliability in demanding environments, both transmitters and receiver feature OLED displays for monitoring system status, signal strength, and battery levels. The transmitters are equipped with L-series battery plates, while the receiver uses a V-mount battery for flexible power options.
