The camera may or may not be working, or it may be one of those new fangled things that doesn't flash all the time, doesn't use film & downloads the results straight away to the CTO (as Tigger pointed out). Only thing you can do is stick it out for the 14 days to see if you get a NIP through the post. To be honest speaking to the police about it won't change matters. Its unfortunate but if its got you, its got you. Most forces now though offer you an option to do an awareness course & should you be unlucky enough to get a NIP there's usually information on the 'Red light awareness course and an option to take it. It will probably cost more than the ticket (about £80ish) but you don't get the points (may be worth it if you drive for a living & need to keep em down). The course is only open to you if you've not been done before in the past 3 years for the same offence.
