I have an AXIS P3225-LV Mk II Network Camera.
It is there for many years, and when I installed it, the image was perfect with daylight and also at night with the IR lightning.
But recently I discovered that the image was not good anymore.
There was dust on the inside of the plastic bulb of the camera.
I cleaned all the dust from the plastic cover (inside + outside).
I cleaned this cover very carefully with water and then dried it very carefully. I did this already twice to be sure I did it good.
I mounted everything back in place as before.
Now, the image in normal daylight is perfect.
Now, the image with IR lights (the camera has three IR lights) and WITHOUT plastic cover is perfect.
The image with IR lights + plastic cover is like in the attachment (beeld.png).
It looks like the three infrared lights are reflected in the image.
What could be causing this effect?
