Camera detected motion

Hello,

My camera is sending notifications to my iPhone and displaying the camera on my Apple TV because it detected motion. I had it set up to only sent notifications and display the camera if specific motion is detected (people, animals, vehicles and packages) within the activity zone. This have worked perfectly for months/years and now since an hour it keeps sending notifications while I did not change any setting. How can I solve this? Changing the setting and changing it back to the way it was doesn’t work.

Looking forward for your replies.
