2mp Camera with fuzzy right side

[rmalbers]

I have an Empire/Dahua 2.1mp bullet that is several years old that has a fuzzy right side of the picture. I unscrewed the outer glass lens cover/metal housing 180 degrees and the fuzzy image was still on the right side so it's not something on the outer glass lens cover. I'm wondering if any of you have seen this before and what you think? Is it something on the lens or sensor that can be cleaned or do you think it's just the sensor going bad? (I hope this is the right place for this question, it's sort of troubleshooting, etc.) Also, I don't see anything noticeable on the lens (the part I can see).

PERPHAPS THE CAMERA OPTICAL LENS IS HAZY FROM CONDENSATION?

I guess it's possible but the inside of outer glass is completely free from any water vapor, it 'seems' dry inside.
