I'm having some trouble getting motion detection to work with dark vehicles at night. I setup some zones in the middle of the driveway and a trigger when an object crosses between the zones going either up or down the drive. This is working great during the daytime, and has eliminated pretty much every false positive I was getting from shadows/sunlight. The problem is the bottom zone does not detect motion when a dark vehicle is going by at night. I've tried adjusting the contrast difference all the way down to 12 and it still does not detect the vehicle at night. Camera is a Dahua 2231 and it has all the default settings
Exposure: Auto
Backlight: Off
WB: Auto
Day/Night: Auto
IR: SmartIR
Blue Iris:
Min Contrast: 12
Min Object: 300
Make Time: 0.5
Object size exceeds: 67%
I've made two videos with motion highlighted and outlined. One with IR and one with color forced, neither triggers motion in the bottom zone (the lower part of the driveway in frame). Is there anything I can adjust to help this?
