> Or, would turning on more lights in response to motion give the AI a better shot? I imagine for this to work, some shenanigans would be required regarding bulb placement, but since these are agricultural buildings I can pretty much do whatever without regard for cosmetics.

The main issue is that most people tend tp purchase cameras for the Megapixels - without looking at the size of the sensor that it is paired with.

Most people would think this is too expensive for a home camera

But it will give you a hell of a lot better image than something like this one

I have the two different versions of these - the larger sensor ones are only used in areas with motion sensors that will activate external lights - the smaller 1.2" sensor is fine with ambient lighting

I use the Frigate Add-on in Home Assistant to detect "person". Microwave presence detectors would trigger on my dog walking into the bedroom. PIR would trigger on anything warm. I am using a cheap $35 Wyze CAM v3, flashed with the RTSP firmware (from Wyze). I have a camera looking at my driveway and any car in the driveway will turn on the driveway light. In my office, any person in the camera view will turn on the office light.
