So I have about 3ish of my 6 camera setup. Been a bit too hot to do the rest. Was working on the PC that was going to record them and finally adjusted all the settings i THINK will work.

Here is a background

3-4K 15fps cameras The costco Lorex ones.
In blue iris, have the 3 cameras continuously recording, and duplicated those 3 cameras to create "trigger" cameras to record clips of the motion, to save to a different drive AND upload them to the cloud (just in case movement happens and the PC is stolen, I have uploaded triggers to the cloud hopefully. Also have the DVR recording in a closet as well as backup x2).

Prior to today, the only thing I changed was "limit decoding unless required" which took my CPU usage from 85-95% down to about 10-12%. Woot! This setting was only changed on the continuous recording streams, and left alone on the Trigger Copies.

So now I do not know if this is just coincidence or not, but I am getting TONS of false triggers. I turned on the "object detection rectangles" to see where it is capturing. And it literally is capturing the suns natural movement that the shadows are creating. I do not see any movement, but the object rectangles start out small, get bigger and bigger and bigger then trigger my object size detection.

My settings for trigger are



and I have adjusted pixel movement to 300 (which I think is too big now) but still getting triggered every 10-20 seconds cause of these movements.



here are just some of the examples of what it looks like with the object rectangles.





Any help with this? or is it literally just a "harsher" sun today?

Best fix is to use line crossing or intrusion detection with sensitivity turned down. I was using motion detection on my front door camera and had constant triggers due to the sun/shadows/bugs/nothing. I moved to intrusion detection and now i have very few false triggers and have never failed to capture a human, a cat, or even birds.

Intrusion detection ? Isn’t that part of the camera not blue iris?
Hi Nyghthawk,

Blue Iris also. Some cameras have that function built in, if you're using Blue Iris - it can handle that itself. ( this is why having a better CPU is good for Blue Iris boxes )
