The Middle Things Middle Tally bills itself as the world's smallest tally system, built to velcro onto almost any part of a camera setup without adding meaningful bulk. It has no built-in battery and is instead powered and controlled directly by a Middle Things APC-R unit connected to a Blackmagic Design ATEM, aimed at productions that want a compact on-camera tally without running a separate power source. A standard USB-C to USB-C cable connects it, so any length cable works, not just the included 50cm one. World's smallest tally form factor: Tiny and lightweight enough to velcro onto almost any part of a camera setup. Powered and controlled by the APC-R: No built-in battery; the tally draws power and status directly from the connected APC-R. Standard USB-C to USB-C connection: Works with any USB 3.2 cable length, not just the included 50cm cable. Automatic red/green tally indication: Lights red for On Air and green for Preview based on the APC-R's status. Requires a Middle Things APC-R: Cannot be used as a standalone device; requires the APC-R connected to a Blackmagic ATEM.
