OUTDOOR CAMERA inconsistent motion detection

Never had issues with indoor cameras but my new outdoor camera does not detect motion all of the time.
If I wave my hand in front of it - some of the time it will detect the motion . Is this an issue with this new camera ?

V3 or Outdoor Cam?


The Outdoor cam uses PIR / body heat detection and is quicker to detect human beings moving across the field of view than it is approaching the field of view head on. I’d never buy another Outdoor model, just V3’s using pixelation to detect motion.
