Since I upgraded to 18.104.22.168, one of my 2 cameras gives me an alert every 5 minutes. I hadn’t changed the alert settings, and wasn’t get alerts that frequently before. I seem to get alerts for both sound and motion. I set either alert to Low sensitivity. The clips for the alert detections don’t show any motion or sound.
Besides fiddling with alert settings, I have unplugged the camera. Nothing changes the frequency of alerts.
