Outdoor Cam has event on exact time every day?

For the last week or so, it always reports an event at 3:41am, there have been previous events due to snow, sun, wind but exact time is really odd. It’s pointing at the garage doors so normally we only get a handful of events daily. Anyone seen this?

Yep. We have an outdoor cam pointing at our back deck… it sends an event every evening at exactly 9.45pm MST. The recorded video just looks like the IR light came on and the resulting change in video brightness triggered a motion detection.
It’s been doing this for about 2 months. I keep meaning to go and try a full reset to see if that helps… it needs a charge so I will do it then.
Quite annoying though!
