Building Trust in an Age of Smart Surveillance

The Project That Opened My Eyes

A transport hub project completely shifted my approach. What should have been a routine camera upgrade became a debate about surveillance, consent, and society. A data protection officer questioned facial recognition capabilities. Privacy advocates challenged our behavioural analytics. Local representatives demanded transparency about data retention.

Suddenly, I was in meetings discussing ethics and accountability, not pixels and processing power. Those conversations opened my eyes. The people asking these questions weren’t anti-technology—they wanted assurance they were more than data points to be analysed.

The Industry Reality Check

The surveillance industry is catching up to where public expectations already are. With the EU AI Act, GDPR, and the UK’s Surveillance Camera Code demanding accountability, compliance isn’t about ticking boxes but rebuilding trust. The old approach of “build it powerful, deploy it quickly, worry about permissions later” doesn’t work anymore. Projects stall because teams can’t answer basic questions about data minimisation. Installations are delayed when privacy implications aren’t considered. Public trust erodes when surveillance systems are deployed without enough consultation.

The challenge isn’t technical. We have incredible capabilities: AI that can detect unusual behaviour, analytics that predict crowd flow, and systems that process thousands of data points in real-time. The challenge is deploying these capabilities in ways that serve communities rather than simply observing them.

How to Build a Trustworthy System

We don’t build surveillance systems anymore; we build trust systems that happen to use surveillance technology. Privacy by design is our foundation. Every project starts with a purpose limitation: What exactly are we trying to achieve? What’s the minimum data we need? How can we build safeguards that respect privacy while delivering value? Intelligent masking, on-device processing, and selective recording aren’t constraints—they’re features that enhance system integrity. Data Protection Impact Assessments aren’t bureaucratic overhead; they’re where we prove we understand the communities we serve.

When a transport operator can show that its behavioural analytics only flag genuine security concerns without storing unnecessary personal data, it is not just complying with regulations but building stakeholder confidence.

The Ongoing Conversation

The surveillance sector is still developing its ethical playbook, and I believe that’s precisely how it should be. Technology keeps evolving, public expectations continue to grow, and regulatory frameworks continue to develop. Rather than viewing this as uncertainty, I’ve learned to see it as an opportunity.

Every discussion with a privacy officer, every community consultation, and every compliance review is an opportunity to show our industry can meet higher standards. Success won’t come from having the most advanced technology, but from understanding that technology is only as valuable as the trust it’s built upon. The future of surveillance isn’t about watching more effectively; it’s about watching more responsibly. That future begins with asking “can we?” and “should we?”
