The Hollyland Syscom 421S delivers enterprise-grade wireless video infrastructure for multi-camera live production environments. Engineered for broadcast professionals managing weddings, sports events, concerts, corporate meetings, and worship services, this system supports up to four transmitters simultaneously with synchronized audio and video across all channels. The receiver provides eight total outputs—four SDI and four HDMI—enabling flexible routing to switchers, monitors, and recording devices without signal degradation.

Built for mission-critical workflows, the system operates across 5.1–5.9GHz spectrum with 40MHz bandwidth and 0.07-second latency, ensuring real-time monitoring during live switching. RS485 and RS422 compatibility provides direct PTZ camera control, while Ethernet passthrough and RTSP streaming integration allow network-based monitoring and remote feeds. Tally light support ensures camera operators maintain visual confirmation of active sources. The architecture scales to 16 transmitters across four systems operating simultaneously, addressing complex production demands without frequency interference.

Each transmitter accepts both SDI and HDMI inputs and operates on 7–36V DC power, compatible with broadcast battery systems. The receiver unit supports 18–36V DC input and includes redundant output configurations for backup switching. All units ship with RP-SMA antennas, mounting hardware, and control cabling for immediate deployment in touring racks or fixed installations.
