I have had 10 or so Airlink101 AIC250 cameras in service for about 10 years now and some of the cameras lenses have become pitted ( Mounted outdoors in birdhouse type housings in Quebec Canada winter & summer)
So I found replacement lenses (6mm) on ebay from china for $2 free shipping.
They screw in the lense holder and focus perfectly.
HOWEVER the cameras have little contrast. The sky is blue but the greens of grass is gray to white.
no amount of adjusting the brightness contrast or saturation helps.
So I bought 2.8mm 3.6mm 6mm and 16mm from differant vendors but thay all have the same no contrast.
This experiment has been going on for the last year....
Anybody seen this effect ???
Thanks
