It is designed to work with Blackmagic Cameras. Most of the ones newer than 2016 do support Tally (Pocket 4, Pocket 6k, Micro Studio 4k, Ursa Mini Pros, Ursa Broadcasts, Studio 4k, Studio 4k Plus, Studio 4k Pro, etc.). For the Pocket Cameras you need to use a bi-directional converter to enable tally and send one sdi in (tally and camera control) and one sdi out to the switcher (for video).
There may be some third party external tally lights that work over sdi from the switcher, but I can't confirm which ones would do that.
