The AVMATRIX Wireless Multi-Camera Tally Light System can wirelessly communicate from up to 200m away. Multiple interface connections on the tally box—from GPIO and USB Type-C to RS-232 and RS-485—create wide compatibility with various switchers and vMix software for integration with your preexisting gear setup. An included antenna can attach to the box to improve its signal.
Each tally light has a front and rear indicator light for its on-air status, as well as indicators to display the wireless signal strength and battery level. They can be powered via USB Type-C input or with a separately available 18650 lithium-ion battery. The bottom of each lamp has a 1/4"-20 thread for installation with a hot shoe to the top of a camera. Five USB Type-C cords, a GPIO connector, a power adapter, and a carrying case complete the system's accessories.
