For CCU intercom and tally with a TVS HD and UMP you need 2 sdi lines to Every camera.
1 from camera to the input of the mixer. And 1 return from the mixer output to the camera.
Wireless is a big issue as almost Every wireless unit is stripping away all un-needed data and audio from the signal to give a low latency signal.
That data is what you needed to control the camera.
You can solve this by hooking up a Network to SDI ursa controller from Skaarhoj. Connect this to wifi and you Will be able to have a wireless camera control
