reason for picture quality problem with sd22204T-GN?

[TVT73]

Hi,
please have a look on these example picture.


Have a look on the coronna effect on the bike and other bright parts. What could this be? A sensor damadge? General quality issue?
WDR is off the rest is on default picture settings. 2DNR and 3DNR is on 7. The dome is clean, no humidity is visible inside.
The mounting position is sun free under a roof.
I can´t remember when this effect has come up. Maybe from beginning. The cam is only 2 months running.

Defog on?

No. I did also a reset to picture default. The effect is still there. Only thing I didn't test was a picture test without dome glass.

Did you try turning WDR ON?
This is a classic example for WDR I think with the camera being mounted in a dark spot looking into an otherwise bright scene. I'll try and post a similar image later today where I have one under roof on the patio looking out into sunlight and the pool.

Wdr is off here some examples with wdr on 30 and sun is shining, the problem is more visible...

Did you say the camera is a dome? I'd be very suspicious of the glass. If you can remove that would be interesting.

That was what I also thought, but my other indoor HDBW with a Dome are ok.
I don't like Domes, but this is the cheapest outdoor ip65 rated and it's just for fun.

Anyway does any other of you have this one?
