Check out the photo for the 2C camera detection - This is why the cameras don’t trip - the detection zone is closer to only 20˚, and maxes out ~20 feet. You can see a lot, set detection zones all you like, but the cams have a very limited detection zone.
When you factor in a delayed response it’s no wonder so much is missed. In my experience these seem best suited for close range interaction. I’ve set everything to record on the highest sensitivity and still, unless I’m within 20 feet of the camera, nothing is going to happen.
What’s weird though, is the cars from the street getting picked up from over 200 feet away, even outside the specified zones - they get recorded, albeit several seconds later.
