Wired flood light/ camera

We’ll…all has been working well with the Summer install of two wireless cams and one wired flood.

But as soon as the cold weather hit (~1 Degree F at night) interestingly only the wired flood has started to act up, only at night - so often that it’s to the point I’ve just turned it off.

Reason being is that every few minutes it is detecting “something” and turning on the camera and the floodlight.

I’ve reviewed the footage over and over again on many of the occasions and there is absolutely nothing in the detection area.

The camera is set to the lowest sensitivity, as well as being set for human motion only.

It has received the latest update and has been restarted multiple times. However nothing is preventing this thing from going off every few minutes and turning on the outdoor lights.

Does anyone have any suggestions?
