Support of "Motion activity zone"

[sy6sy2]

Is your feature request related to a problem? Please describe:
Just discover that official HomeKit camera can use a motion detection based on activity zone (see picture above).
I understand that this plugin can trigger a notification on motion detection thanks to https://sunoo.github.io/homebridge-camera-ffmpeg/automation/motion.html but I am unable to find here if the plugin allow to have this activity zone feature, can someone tell me if it's possible?

Thank you!

You should be able to do anything you’d typically do in Motion. I haven’t used it myself, another user wrote up that guide.

Thank you for your answer.
I just investigated about this feature and I found that it's related to HomeKit Secure Video.
And if I understand correctly you are still on the road (#1200) 😉
