ULEZ cameras are the cameras used by Transport for London (TfL) across the capital to monitor the cars that enter and exit the Ultra Low Emission Zone (ULEZ) . The cameras record drivers’ number plates, which then get checked against a database to see if the vehicle complies with ULEZ rules. If it doesn’t, then the drivers get charged a daily fee of £12.50. So far, 1,775 Ulez cameras have been installed in London, and TfL will continue to put more cameras up until it reaches its target of 2,750. While the cameras aren’t able to cover all entrances and exits in the Ulez zone, TfL hasn’t disclosed which ones these are. However, there are entrances to the Ulez that dont have cameras or where cameras are in place but have been disabled. The ULEZ cameras work by scanning a vehicles number plate and checking if it is compliant or not within the low emission zone. It will then see if the driver has prepaid the charge or not.
