Just to add to the mystery, I have a single V3 with CamPlus Lite (just like my other 12 or 14 cameras, a mix of V2s and Pans) and it isn’t doing any person detection. It’s running the RTSP firmware 4.61.0.3. It has been working fine and suddenly stopped doing Person tagging or notification. I turned off all detection and let it sit for a day or so then turned it back on. Worked correctly for a day or so but now has stopped Person detection again.
Something flaky on the Wyze servers.
