Corner mount for Gen 2 motion detector

Hello having issues with corner mount using 3m adhesive. Is there a corner mount I can install with screws and anchors that I can then mount the motion detector on? Motion detector fell off the wall in the middle of the night. Surface was cleaned with rubbing alcohol before mounting with corner adhesive. Flat mount won’t work because field of view of motion detector needs the corner.

The gen 2 motion detector back bracket comes pre-drilled with holes for screw mount. I would never trust the adhesive on those large sensors. Mine are screwed in. Ring does not include the screws, BYOS.
