It’s a tough one, at least in the summer where I live. The bugs are big and love to fly so close to the cams that you’d almost have to turn motion detection completely off to miss them.
You can turn off motion alerts and leave Person alerts on, so it’s less annoying, but you still have the 5 minute cooldown between every event.
The PIR detection system on the new Wyze Outdoor cam should be better at eliminating these false positives than the pixel based detection on the V2 / Pan.
