Poor Image Quality Over Time

[Muhannad_x]

Hello,

I have four Hikvision surveillance cameras (high-end model: iDS-2CD7AC5G0). The image quality used to be excellent, but after 2.5 years, I started noticing a decline in clarity.

I attempted to fix the issue by disassembling one of the cameras and cleaning the outer glass lens cover. Unfortunately, this made the image quality even worse, so I did not repeat the same process with the other cameras.

Now, after 3 years, the image quality has become poor on all cameras. After further observation, I believe the main issue is related to the external protective glass/lens cover.

I contacted the local Hikvision distributor in my country, but I was informed that this part is not available. I also contacted Hikvision directly, and they told me they do not sell this part separately. Additionally, I checked with several suppliers, and none of them offer it.

I would appreciate your help if:

• Someone has experienced a similar issue
• The replacement glass/lens cover is available from any reliable source
• There is any alternative solution to fix or restore image quality

Thank you in advance.

Have you tried an actual polishing with some protective gel or something?
