This is an Ealing bus lane PCN, so you can only see the video on-line. The video can be seen here: -

So it seems the video record shows the contravention is made out, but can this be used as evidence at the tribunal ? Well, the camera certification and authorisation issue was once a hot topic, and may still be. Our administrator can talk you through this.
