Hi all,

I've had 6 of these cameras for about 5 years. The picture quality is good during the day, but in the evening it's very poor.

I only realised a while after purchasing that dome cameras have inherent issues with nightvision IR. Apart from (this significant issue) the cameras have been working fine.

I have searched the net for solutions and have tried the most practical solutions:

- cleaning the lens inside and out
- ensuring the foam ring is secure and gap free between lens and glass.

Other then the above, would the position of the cameras be affecting the issue on all 6?

One camera has a lot of noise in nightvision too.

Any suggestions to salvage these otherwise decent cameras.

I have read the specs :

Min. illumination 0.028 lux@F2.0, AGC ON

This cam is not the best for low light pictures color or B/W.
You have IR reflection , try to reduce the contrast

try with these settings for night mode :

Changing the contrast made a minimal difference.

Exposure settings:

Iris Mode: Manual
Exposure Time: 1/30
