my outdoor cam has cam plus and is mounted above the garage door. it detects motion sporadically. the best it’s done is catch me when i drive out from the garage but fails to detect my return. it misses the mail carrier, dog walkers, me walking across the PIR field to test it…
i filed a ticket with support and followed their troubleshooting instructions but no joy. I’ve also iterated through variations of distance and sensitivity settings without success.
Something you might consider trying is aiming your camera a little higher. I originally setup my cameras aimed low to get more view of my yard and less view of the sky and they wouldn’t detect anything unless I was standing directly under them. By the time they detected me pulling out of my driveway and started recording I was already long gone.
