OK, so this looks like a bay on a red route, so cannot be enforced by CCTV. However, as you haven't posted-up the PCN we cannot tell if the PCN was issued by a CEO or using CCTV. If it was CCTV then the PCN was served unlawfully, following a case at London Tribunals. However, Transport for London have taken the matter to judicial review, so it is not a final decision.
