I have been looking at this project and note the following. The camera images of two years ago are very clear compared to those of today. To explain I have linked two images, one from today and one some years old.
This image is from the 4th June 2011.
The difference in Image quality is remarkable. Does the camera deteriorate over a period in the weather?
There is a marked difference @8077 in the images. I do believe the cameras fade over time and I will plan replace the camera #2 in the first quarter of next year. The image from 2011 is much clearer I agree.
