Why are my Arlo indoor cameras making random chime sounds?

[Kbear08]

Every few weeks I hear a random chime type sound coming from an arlo indoor camera. It sounds similar to the sound it makes when a camera pairs. I can’t ever tell exactly which one it is (I have 3 set up with different viewing angles in my open floor plan kitchen/living room/dining room). It happens at random times… Is this due to a firmware update or something like that? Is there a way to turn off this sound? When it happens in the middle of the night it sets the dog off on a barking rampage and wakes the entire house up.

Honestly don't know... I have 3 setup and haven't seen/heard this.

Only thing I can suggest it to remove one camera at a time and then bring it back online as new... if done over a few days you may find out which one it is ( in case it's a defect ).

Also I would check the firmware of each camera to verify all are the same.

What other Arlo devices do you have? Have you checked modes and rules to see if that could be related?
