Lilliput TS3019-4 AVMATRIX Wireless Multi-Camera Tally System

The AVMATRIX TS3019-4 addresses a persistent multicam production headache: running tally cables to cameras across a venue. The system transmits tally state wirelessly at 433MHz with up to 200 meters of line-of-sight range, covering the footprint of most corporate event spaces, houses of worship, and mid-sized broadcast studios. One tally box connects to the production switcher via GPIO, USB, RS-232, or RS-485 — giving it a broad interface footprint for switcher compatibility. The RS-485 wired connection isn't just a spec checkbox; it's a real fallback for environments where 433MHz wireless gets crowded by other RF systems on the same floor.

The four tally lamps included in the kit mount via standard 1/4-inch hot shoe — clean integration with any camera that has a hot shoe, no custom brackets required. Front and rear indicators mean the talent in frame and the camera operator behind the viewfinder both get a clear cue. Battery power via 18650 cells keeps operators mobile without a cable connecting their lamp to anything. The system scales to 16 lamps, so a 4-camera configuration today doesn't strand you when the production grows. Verify your switcher's tally output interface against the supported list before committing — this is where compatibility issues surface, not in the wireless performance.
