I stated this in a reply to a previous thread on this issue. But I am having the exact same problem. Again, I have my camera at the top of an inside window that points outside to my driveway. I'm in the United States.
I bought this just this past week. I am running firmware 1.06.02 hardware A.
It goes all white at some point in the morning.. even though I have it pointed down towards my driveway.. the sun still overpowers with light and for some reason, causes the camera to go FULL WHITE.. and stays that way all day long until about dusk time when the sun starts to go back down.. then it goes back to normal.
However, one way to reset this issue (until it happens again which is pretty much right away since the picture is super bright with the sun out), is to go to the webUI->Setup->Audio and Video... here, if I change the resolution, it corrects the camera... next time, I'll try changing the bit rate and/or frame rate to see if that temporarily fixes the issue as well.
This is my 1st cam.. so far, it's "ok". But this all white issue is enough to get me to return this product and try another brand.
