The camera works fine but there is a white spot (see attached photo) that has developed that is most visible at night when it is dark out. A little visible as a blurry area in the same spot during daylight conditions. I checked and there are isn’t any dirt or smudge on the exterior lens. Is there something else I should check?
My two guesses woud be condensation entered the unit (just a small drop will do this as I had this happen with an older sytem of mine) I would suggest bringing it indoors for a few days and letting it dry out and seeing if that is the problem.
Other is the reflection of the light off an object casing the spot. Can also happen in the day if the sun hits the object just right.
