Sorry, I wasn't for a minute suggesting foul play in your amazing images of your wild visitors :-)
You've got a really good webcam there. The one I bought (a Philips egg-shaped thing 640x480@30fps) is nowhere near as good. I was hoping it would catch the filthy sod who let his dog dirty on our doorstep. Poor quality pictures maybe, but it did still catch the culprit - it was our Wayne all along! Too lazy to use the bog upstairs!
I defended in jest, no offence taken. They are all fake foxes on my webcam, I cut them out of a book, painted them brown, stuck them onto hat pins and move them about every 30 seconds
If you look at the archive, you will see at the beginning I had an extremely poor quality webcam, I got off Amazon for less than £4, delivered from Hong Kong. I wasn't expecting much, but it was even worse than I expected it'd be. Truly awful.
The one I'm using now was in a sale in Maplin a few months ago, about £14, native resolution is 800x600 and has manual screw adjust focus, which is exactly what I wanted for the garden. The fancier autofocus would let me down I think, and fixed focus is likely to be fixed too close to the camera. A nice traditional manual focus was exactly what I wanted, quite pleased with it, though there's always room for improvement
