I have a Dahua IPC-HFW5241E-Z12E for recording license plates passing by. The "glass" (probably plastic) started to get a bit yellowish and murky, reducing image clarity significantly. It has been out for probably 5 years or so and it faces the morning northern California sun at probably around 45 degree. It can be fairly intense during summer but not much I can do about it, I think. In any case, is there a way to fix it? I did my car light covers before with sending it down and putting a new UV protectant on. However, while initially I was very clear again, within half a year or so it got worse again and I suspect the same would happen with this camera if I did the same. And I don't feel like redoing this every 6-12 months.
