CCTV for London Businesses: What You Need to Know
From camera placement to GDPR compliance, here's what every London business owner should know before installing a CCTV system.
CCTV is one of the most effective tools a business can have — for deterring crime, protecting staff, and providing evidence when things go wrong. But a poorly planned system is barely better than nothing. Here's how to get it right.
Start With a Survey, Not a Camera Count
The biggest mistake businesses make is buying a fixed number of cameras before understanding their coverage needs. A professional site survey identifies: entry and exit points, blind spots, lighting conditions at different times of day, and where evidence-quality footage is actually needed versus general deterrence.
Eight well-placed cameras will outperform sixteen poorly positioned ones every time.

GDPR and CCTV: What London Businesses Must Do
If your CCTV captures images of people — staff, customers, or members of the public — you are a data controller under UK GDPR and the Data Protection Act 2018. You must:
- •Display clear, visible CCTV signage informing people they are being recorded
- •Register with the ICO as a data controller (ico.org.uk) — annual fee applies
- •Only keep footage for as long as necessary (typically 14–31 days)
- •Have a documented reason (legitimate interest) for each camera
- •Be able to provide footage to individuals who make a Subject Access Request
- •Not position cameras to capture areas where people have a reasonable expectation of privacy
Cameras pointing at public pavements outside your premises must be carefully justified and signposted.
Recording, Storage and Remote Access
Most businesses store footage on a DVR (digital video recorder) or NVR (network video recorder) on-site. Make sure the unit is secured — in a locked cupboard or cabinet — so that a burglar can't simply take the recorder along with your goods.
Remote access via a smartphone app is now standard on most modern systems. This lets you check cameras live from anywhere, review playback and receive motion alerts. Consider who in your business should have access and set up individual user accounts with appropriate permissions.
Maintenance Matters
A CCTV system is only useful if it's actually recording correctly. Camera lenses get dirty, hard drives fail, and IR illuminators degrade over time. An annual maintenance visit checks recording health, cleans cameras, verifies playback, and replaces failing components before they leave you without coverage when you need it most.
