Motion too sensitive at 1%

[Snail79]

I have my motion detection AND sensitivity both set at 1% and STILL receiving alerts for vehicles crossing the path of the cam at 30 feet away. Cam is mounted 10ft above the ground centered over my downsloping driveway aimed at the street.  I find the ONLY way to stop continuous alerts is to disable them all together.   I'm totally baffled...  ANY suggestions?!?!

Vehicals passing generates heat from the vehicles. The heat will almost always trigger motion on your camera no matter how sensitive the cameras are set. And the heat will trigger motion well past the 15 foot area the cameras are supposed to react to. It's just part of the design of this system. I have 2 cameras in my driveway that almost half of the motion triggers are caused by passing cars more than 50feet away.

I appreciate your comment although NOT what I was hoping to hear as logical as it might seem.  In the meantime I found this posted by Astroboy86.  Won't be able to try it for a week or so.
