Assess my detection zone and placement (street with trees, plants)

Yeah, that’s definitely something I’d want to enable since you said you’re using Cam Plus. If you’re getting “Complete Motion Detected” notifications from generic motion detection, then you should be able to turn those off. (This is one post that discusses it on certain camera models. I’m not certain if you see the same options for your particular cameras.) I didn’t see you mention this specifically, but it might be worth checking to reduce unwanted notifications even further.

I would do this anyway, but I just like having continuous microSD recording on my cameras as a matter of preference.
