DCS 930L How to detect motion

so im able to view the camera from the home assistant overview page and i also do have motion enabled on the camera, what do i use as a sensor to detect any motion then use tts.google_say to play to entity id?

Hey, did you ever solve this?

I’m looking to buy the same camera and I’d also like to be able to use the motion detection from within HA.

Cheers!
