How do I save a CCTV snapshot using OpenCV and Scrypted?

I’m using Scrypted and OpenCV to manage some CCTV camera’s that don’t fully support ONVIF.

Is there any way that I can trigger OpenCV to save a snapshot directly from HA?

For example, I want all of the cameras in one area to take a snapshot at the same time when a motion sensors is tripped so that you can see the same scene from multiple angles if someone enters a certain area.

I know very little about coding, so some sample code would help more than instructions on what to write.
