Have never had any issue with ours. they never miss a thing almost to the point its annoying. But to be fair, I have the motion and alert setting very relaxed. If you drive or walk in front of my house, you will be recorded, which is exactly what I want. Living on a cul de sac we do have significantly less traffic which helps limit the alerts but because of the ring, I know which cars are supposed to be driving down the street late at night. I can always tell which cars are lost or not from our neighborhood.
