Can my gym have cameras — and what about the changing room?

The gradient is stark. Absolutely prohibited: changing rooms, showers, saunas, toilets — spaces of undress are protected by criminal law across our 33 countries, and “we had thefts from lockers” buys no exception; the lawful anti-theft answer is better lockers and a camera on the corridor outside the changing-room door. Finding a lens in these spaces is a police matter first, DPA second — treat it like the hidden-camera playbook: photograph in place, report, don’t negotiate. Conditional: the training floor, entrance and till — the standard business-CCTV rules: real purpose (thefts, incidents, insurance), signage, short retention, no audio, and no camera angles that function as member-watching entertainment for staff. 24/7 unstaffed gyms lean on cameras for safety monitoring — defensible, but the DPIA-grade version, not a webcam wall. The creep cases regulators punish: cameras feeding social media (“look at our busy floor” posts with recognisable members = publication without consent), facial-recognition entry as the only option (biometric entry needs a non-biometric alternative — see biometric locks), and trainers filming clients for marketing without a signed yes. Your rights as a member: the camera policy on request, footage of yourself, and objection when placement exceeds the stated purpose.
