Black dot on camera

Is this a sensor? I am installing the cam and wondering if is OK for it to be covered or blocked?


Yes ok to cover, for both v1 and v2.

That’s vestigial from an old Xiaofang model that had a PIR sensor there. I have never seen a picture of one with a PIR, but have seen photos’s of early 2017 boards with Silk Screened PIR1 and 3 holes for leads. EDIT: Found one the iSmartAlarm Spot.

It’s easy to verify. Put a wide rubberband around the camera (I used one that was holding 3 stalks of Broccoli together).

In v2 the top hole above lens is no longer used.
