With one transmitter feeding four independent receiver outputs simultaneously, production teams can monitor and route 1080p signals to switchers, monitors, and recording devices without cable runs up to 1,800 feet. The 0.07-second latency ensures tight synchronization between camera operators and technical directors during fast-paced events.\u003c\/p\u003e\u003cp\u003eRS485 and RS422 interfaces enable direct PTZ camera control through the wireless link, while integrated tally light support keeps camera operators informed of program and preview status. The system's LAN port provides Ethernet passthrough from receiver to transmitters, enabling network-based camera configuration and RTSP streaming without additional cabling. Scalability to four simultaneous systems supports complex productions requiring up to sixteen wireless camera feeds.\u003c\/p\u003e\u003cp\u003eDesigned for broadcast crews, event production companies, and house-of-worship technical teams, the Syscom 421S replaces long SDI cable runs in sports venues, concert halls, conference centers, and ceremony locations where cable management is impractical or impossible.
