See the blizzard-like reflection from the camera, cool/crisp/clear night in CT. It is unusable:
Is this solvable, should I return, or is this expectation of the current state of tech?
The shared link has timed out at 24 hours so no longer visible. However, remember that the IR LEDs will light up moisture in the air as well as clouds of bugs, making it look like a blizzard. It's similar to using high beams on your car during snowstorms - the light is to close to the axis of vision. Nobody can fix that. We had fog here in Rochester, NY the other night and I got videos that sound similar to yours. A workaround is to have external lighting so the night vision LEDs aren't the source of illumination.
I'm not talking about a foggy night-- I would expect this behavior on foggy nights and it makes perfect sense given how IR works/reflects off water vapor. I found it perplexing that even on a clear night, with what I perceive to be little moisture when compared to a foggy night, the reflection is still this bad. I'm an engineer by trade/nature and now I'm intrigued enough to tinker.
