Real Camera Recording + Take Recorder

Hi everyone, i’ve started working like unreal development in a Virtual Produccion company a few weeks and now I’m trying to start the Take Recorder when a Blackmagic camera is start recording.
The input of the camera can be with a Blackmagic video card or an AJA video card.

I saw in this video ( UE4 Virtual Production Triggering Take Recorder from the Controller using C++ and Blueprints - YouTube ) the guy can controller the Take Recorder with a xbox controller

Has anyone any idea if it can be possible do something for start the Take recorder when the real camera is start recording? Thx!
