#The Challenge: A System Under Pressure
Across the UK there are millions of CCTV cameras in operation, many of which are under the control or influence of public authorities. Councils rely on this surveillance infrastructure to deter crime, manage traffic, monitor anti-social behaviour and enforce parking regulations.
Parking is a critical revenue stream. According to the RAC Foundation, UK councils generate more than £1 billion a year from parking related income. Parking penalties lead to disputes, appeals and legal claims, each of which may involve video evidence.
Where video exists, requests follow.
Subject Access Requests and the Reality Behind Them
Under the UK GDPR, individuals have the right to access their personal data. In practice, that includes CCTV footage. While Emma Dowell says subject access requests at Conwy are relatively low, they’re not straightforward.
Most requests come from incidents such as ‘trips and falls’ or road traffic collisions. Many are from solicitors operating on a “no win, no fee” basis who encourage individuals to get footage to support claims. In those cases, the request is not just administrative, it’s financial and legal in nature.
The Information Commissioner’s Office (ICO) is clear: when responding to subject access requests (SARs), only the requester’s personal data should be disclosed. Everyone else in the footage must be obscured.
That redaction requirement turns even a short clip into a technical challenge.
A Patchwork of Workarounds
Before they adopted a specialist redaction solution, Conwy used a mixture of workarounds that will be familiar to many local authorities.
In some cases, requesters were invited into council offices to view footage privately. While practical, this approach does not sit well with GDPR principles. Informed requesters insisted on getting a copy of their data, which can’t be provided lawfully without proper redaction.
When redaction was necessary, the task fell to the council’s marketing team. This was far from ideal. Pixelating footage manually is slow work, especially when multiple people move in and out of frame. A single request could take hours, sometimes days of staff time.
Emma Dowell also looked into outsourcing. But quotes came back at around £400 per video, which quickly made this option unsustainable in the public sector.
