**Reference**

> *Tally light is a small signal-lamp on a professional video camera or monitor. It is usually located just above the lens or on the electronic viewfinder and communicates, for the benefit of those in front of the camera as well we the camera operator, that the camera is 'live' - i.e. its signal is being used for the 'main program' at that moment *

**What is Tally?**

Tally Controller is connected to ATEM switcher (Multi-camera production switcher). ATEM basically supports wire interfaces to control the camera. Tally Controller can extend the wireless connection for multi-camera devices.
