Fast movement detection is a problem at night with moths attracted to
the LEDs on the cameras
I've tried increasing the number of frames movement is detected up to
10, but at that setting me wandering under the camera
at about 5mtrs range is ignored , yet the moths still trigger motion.
The older cams dont give so much of a problems as the light level from
the LEDs is lower.
Are there any settings which will cause motion to ignore rapid movement
, ie an insect flying in front of the cam,
yet still trigger on a small mammal, cat, dog, etc 4~5 mtrs away,
Or maybe delete video files less than 500K , the frame rate from the cam
is 25/sec,
At night is like watching an image through a meteor shower.
Open to ideas,

The way I've dealt with false positives is to admit defeat! So I put each
event in a separate directory so it is easier to delete the whole event if I
want to.

If you have a section that you do not need to record, you can make a mask
file for that section. I haven't been able to do much about car lights, I
have the same problem.

Turn off the IR LEDs and mount a separate IR light somewhere else. The
moths will be attracted to it instead of the camera.
