Help detecting people sunbathing.

[JNDATHP]

My use case:

I have a couple of cameras that monitor my pool area for person. If a person is detected it resets a HomeSeer timer to zero where it climbs up to 20 minutes. After 20 minutes with no detection of a person, HomeSeer locks our doors to the pool area, turns off the Sonos speakers and if at night, turns off the lights to the pool, LEDs around the pool cage and the lights and water heater in the outdoor kitchen area.

My dilemma is that people will lounge in our chaise lounges and not move very often. In the chaise lounge area, the person detection can get as low as 40%. I tried to figure out how I could have different confidence levels in different zones but failed.

I’m looking for suggestions that will Alert when a person is sunbathing.

Thanks

Maybe you could install a PTZ and have it sweep every 15 minutes. It should 'see' the non-moving sunbather, right?

Maybe the loitering option available in some cameras?

My cameras are mostly HDW5231R-ZE models.

I should add that this is really a first world problem but, heck, I like home automation.

Sounds like a great excuse to get a thermal!

@Arjun probably has some ideas
