I wonder if you might have any insight on why these are so failure prone? I have had this happen twice since buying these cameras a little over a year ago. This would seem to be a simple part, kind of like an led bulb, typically they just don’t fail before other parts of the device have just gotten old and broken down. I know others have been having this exact issue also.

Ash Miller -

Hello could you provide any information on part number and where to buy replacement motion sensors?

TIA
