Doorbell went off without someone at the door

Has anyone noticed the same problem. It went of twice in 30 minutes time. Camera shows nobody at the door. Other security camera did not register any movement at the door.

I’ve had the same issue before where my door bell camera would consistently ring without anyone there. It consistently went off for a good minute or so.

I restarted the doorbell and it has seemed to have fixed the issue for now.
