Motion detection settings for moving shadows

[dgold21]

What's the best way to set up effective motion detection on 2x32 cameras when I have shadows from trees that come into the picture in the late afternoon and wave around setting off the trigger constantly? I've tried to dial back the sensitivity/threshold but that makes it not sensitive enough to trigger anything at night. Trying to find a good balance...do the advanced detection features (line crossing, intrusion) come into play here? I'm a Hik newbie, so I'm not real familiar with these settings. Thanks!

I use motion detection to put red lines on the recording but only line crossing to send emails and I almost never get any false emails.

Use line crossing or intrusion detection for reduced falses.

I do get the sun/cloud/sun motion detection false but that's normal according to the generally accepted views. The guys say intrusion detection works good as well.
