Tally Bridge

The Tally Bridge is a small fanless device that watches one or more tally sources and shows program, preview, and ISO state in real time on a web UI any device on the LAN can open. No vendor app to install, no per-seat licensing, no software pinned to a specific operating system.

What it actually does

• Reads tally state from Blackmagic ATEM switchers, TSL UMD streams, or vMix, in any combination
• Pushes updates to connected browsers in real time, with a feel that keeps up with live cuts
• Shows program, preview, and per-source state on a card-based grid that scales from a phone to a large monitor in the back of the room
• Drives Canon XC PTZ camera tally lamps directly over the network, so the talent sees red without extra wiring
• Runs in light and dark themes; the dark theme is what most operators leave it on
• Identifies inputs by name once you label them on the switcher, so the cards say "Pulpit" or "Drum cam" instead of just numbers

Why a bridge

A modern production pulls tally from several places: a switcher, a graphics box, a recording rig, sometimes all three. Stitching that together into a single, glanceable display is the kind of work nobody wants to do twice. The Tally Bridge does it once, well, and keeps doing it across services, restarts, and network blips.

What you avoid

• Per-seat tally software licensed by camera count
• A laptop running a "tally server" that nobody can reboot during a service
• Custom wiring for tally lamps to PTZ cameras
• A web UI that only works in one browser
