2 Cameras at night with unusual abberations

[THEGreenBoxInc]

Not really a BlueIris issue, but in the last year at one installation 2 cameras exhibit slight fogging affects, but seems only at night and independent of external conditions. At first thought maybe bottom one was IR interference, but just turned IR off and no affect. Not cold enough (50's now) to be fogging due to some condensation (at least I wouldn't think). Anyone have any other ideas? Both cameras are clear as anything during the twilight and day. Top one could just be ambient light and very high position ... but bottom one was fine 6 months ago....

Since you ruled out IR bounce, it looks like they need a good cleaning or they have been cleaned too much and have microscopic abrasions that become more apparent in the nighttime. Or sun faded.

Are these dome style cameras? If so the dome is the problem, dust dirt, condensation don't mix with IR light very well.

I've had something like that happen to a camera due to condensation inside the camera. It only fogged up at night. I brought the camera inside the house, opened it up to let it dry out, and replaced the desiccant pack with a new one. Problem fixed.

what the what is a desiccant pack? like a moisture absorber?

Yup. I've had to do the same thing. A bullet started fogging because the seal went bad between the front/lens cover and the body.

Yes, it's a little packet of moisture absorbent material.
