During the day they are mostly useless outdoor. During the night position them where there's not much infrared pollution. I used to get random on/off from car lights reflected off home. I used to get notifications from cats and birds too in the middle of the night. I got small aqara sensors that you just glue to places and just moved them around until I got good spots. Also, if they go on they just turn on lights so not much of an issue. Alarm is not driven by them but by smarter cameras.
