you ought to be able to set your webcam up to do this

but thinking about it, if you just let the webcam run, ideally with the video datestamped, it would illustrate the problem from start to finish so to speak, would it not ? of course the council would have to watch it - you could watch it afterwards and manually note the times to save them time watching it all

even if it is not date stamped it's a start as long as the location is clearly identifiable which it must be anyway; a video diary with notes is as good as a written one here if not better ?

be good if some of your neighbours could do same...
