I need help to setup my camera I always have trigger because of sun I use BI4. I don't know how to post a video to show my problem. Any help will be appreciated. P.S. my english is not terrible. Thanks in advance.

I find that zone crossing is a more reliable motion detection technique and avoids many of the problems with sun an shadows.

You set various zones in your field of view then say "trigger when going A to/from B or from B to/from C"
