Red Traffice light camera London

[CMP]

The Metropolitan police claim that I went through a red light 11.8 seconds after it went to red on the busy A41 in Finchley at 12:04hrs,the alleged incident took place a month ago and I do not recall anything about it. I find this impossible to accept and do not recall the incident and if in fact it had happened I would have had problems doing this due to traffic crossing this busy junction. They will not supply the photographic evidence and my question is can these cameras make mistakes and go off when the lights are in fact green and not red. 11.8 seconds is a long time. Does anyone know the answer to this? Can I win in court? The Police told me it took them a long time to inform me as my car is a company car, this however makes no sense to me as I am the one being asked to say who was driving and who can remember things in deatil that took place 5 weeks ago.
