Where it landsOne national portal handles driving-offence video from dash cameras, helmet cameras and cameras mounted on houses, then routes each upload to the force covering that stretch of road. Anything filmed in Cardiff goes to South Wales Police.
Fourteen days, and no extensionOnce the date passes, picture quality counts for nothing — with most offences, the registered keeper needs that notice in hand within fourteen days. South Wales Police publishes its own submission cut-off, and reading it before you upload saves wasted effort.
What is asked of youKeep the other vehicle's registration handy. You will be asked to set out what happened in a signed statement, and a court appearance is possible. The video carries the facts, but you are the person standing behind it.
Cameras your staff wearWhen an employee's body-worn camera records identifiable people, that is personal data, so UK GDPR bites: a lawful basis, signage where it can realistically go, a retention window you can explain, storage that is properly secured. Handle evidence as you would CCTV — keep the originals, hash the copies, note each hand-off.
