How to sync camera hotkey with crestron control ...

How to sync camera hotkey with crestron control system integration?
Asked by: Kelly John
The Lumens VS-KB21N IP Camera Controller with NDI and Crestron control systems cannot directly communicate or sync with each other. The KB21N is a standalone hardware controller that sends VISCA commands directly to cameras but does not support feedback or integration with third party control systems like Crestron.
