Solutions: Camera Detecting Motion Outside Arlo Activity Zone

1. Check for Audio Alerts: Are you sure that audio alerts on your cameras are off? Know that motion detection also works in relation to audio/sound alerts. Therefore, there is a high possibility that the camera is detecting motion because of the audio. So, check for audio alerts and disable them.

For your information, you should enable sound detection on at least one of your cameras in either ARMED or CUSTOM mode. This will help you receive relevant alerts.

2. Turn Off HDR: Your security camera might also detect the motion outside the Arlo activity zone if the Auto HDR feature is being applied. In case your camera detects an image that gives a clearer view in HDR, the feature gets applied automatically. The feature is enabled by default and you are required to disable it.
