Poor motion detection at a distance

Post by bigmonk »

I'm using ZM 1.22.3 and have it installed on 3 different machines with different camera setups. All have very good cameras but I get no motion detection at a distance (over 20 feet or so). Up close it works great. I've tried to reduce the blend % to 3, reduced the number of blob frames, etc.... all that I can think of to make it more sensitive but still no detection at a distance.

you need to drop the pixel count, have a try using pixel rather than % and leave the blend at 7

I am getting this exact same thing happen to me. Can you tell me if the previous post worked for you, or if you found anything that did work?
