Anyone solve palm tree shadows?

[Starman66]

I have two palm trees on my divider between the street and sidewalk that throw wicked shadows that move across the sidewalk at different angles throughout the day. I need to record anyone walking on the sidewalk in front of my property and the alerts are mostly shadows. BI used to work well with cancel shadows in earlier versions but seems to be useless now. I have tried numerous "crossing zones", size, contrast and trigger settings, all to no evail. Anyone have any luck with their settings they can share?

Thanks!

(Just kidding - I have a similar problem in my front yard with some willow trees that blow/sway and trigger constantly)

Have the cameras set to continuously record now because I'm afraid will miss something. Not good

disk space is cheap, I have 7 cameras all recording 24/7 and I have over 3 weeks of archive on 10TB

motion recording is designed to save disk space, getting a bunch of false alarms is par the course for outdoor uses.. more often than not your going to get dozens, perhaps hundreds of false events for every one thing you want.. but then you still risk missing stuff.

Ive gone back through my footage and found kids carsurfing, sounds of neighbors windows breaking off in the distance, nearby gunfire, wildlife, etc.. none of which would have been recorded if I was relying on strict areas of interest.

yea, I guess I was just spoiled before when cancel shadows (Gaussian) worked well. So be it for now I guess until a future update?

Has nothing to do with disk space. You can have both, full recording and motion alerts and if you get ton of false alerts it becomes a burden to review them and making it useless. I have tree shadows too, but this hasn't been a huge issue in my cams with motion alerts set in NVR, maybe 1-2 false alarms from tree shadows per day.

Agree regarding being a burden and rendering the alert process useless. That's a big plus for the BI software and now can't really use the feature.

alerts outdoors has always been useless, its too dynamic of an environment for video.. with a couple false alarms per day who actually pays attention to real events? I just use it so finding activity in a recording is easier.. reviewing 12h of footage at 8x speed sucks, but with motion flags you can quickly go through all the actual activity.

99.999% of my recorded footage gets overwritten without ever being played back, I dont go through and check activity.. yet when I get an alert someone's opened a gate/mailbox/door/window with 100% accuracy and I respond instantly.. it happens pretty much never under any normal circumstances, so when it does happen it really gets your attention..
