Re: Apathy is the problem
"you can specify the distance from the camera at which motion triggers them."
Vaguely. What happens is more of the frame has to see a change in a certain time interval for it to trigger. It could be a person a couple of meters away or a removal van even further away. It could also be the shadow of a bird since the system doesn't determine what's in the frame, only that a certain percentage has changed rapidly enough. It might also trigger from a tree branch swaying in the breeze or reflections from a dangly ornament.
