every night's a blizzard

[elmunc]

Every night my video feed looks like this. It's as if there is a blizzard in front of the camera, or swarms of tiny insects flying around. No problem during the daytime. I have the most up to date firmware. Can anyone explain what's happening, and what I need to do to fix it? Thanks.

Anything that reflects the IR from the night vision LEDs will show like this. Having it happen all the time implies a rather moist (fog or similar with droplets in the air) or dusty environment. Have you tried reducing the motion sensitivity in your Default Mode Settings or in the modes and rules? What about using the spotlight (color) instead of the IR LEDs (B&W)?
