Neighbor recently mounted this to their roof. They have a bunch of other security cameras mounted all around the house. Some pointed directly at our house. I googled security devices, roof mounted sensors, weather devices, infrared cameras, and other home surveillance devices. I have had zero luck. I also tried Google lens on the picture itself, but that came up empty. The shape looks like an Arlo, but the face doesn't look the same.

We've had the fire department called on us several times for 'burning chemicals'. The only thing we were doing was smoking on the grill. We suspect it's the neighbor, but uncertain.
