Strange moving spots at Night with Doorbell Pro

Almost every night our movement detection gives a notification that something is moving. We’ve selected "only movement of people"in the doorbell settings but it still reacts on these strange moving spots. It’s not rain or any insects. Does anybody knows what it is?
Attached a link to the video of what I mean.

Hi @Arnevb. It looks like the video link didn’t post properly, would you mind sharing it again? When attaching this video, you will need to first gather the share link of the video. You can do this by going into the Event History in your Ring App and choosing to share it via email. From there, copy the link that is generated and paste the link in the body of your post. In addition, you can upload this video elsewhere, such as YouTube, and then share the link to the video in your reply. Once the video is shared, a member of our team or another member of the Community can take a look and offer some helpful suggestions. :slight_smile:
