I just installed my 1st Floodlight Cam (on my Patio).
I noticed there is a “Collar” at the top of the neck between the Camera / Motion Detector & the base.
That collar has a hole that goes through the collar which leads me to believe that a bolt should go through that hole & be secured on the other side by a nut — to tighten that collar.
Congratulations on your Floodlight Cam, we hope you enjoy its capabilities! When you get a moment, please response with a picture example of this part on the Floodlight Cam, and I’ll be happy to assist further
