For security professionals, the technology presents an opportunity to strengthen identification and support frontline operations. But its growing use is also bringing renewed attention to accuracy, privacy and how biometric technology should be deployed.

A growing role for biometrics

Live facial recognition (LFR) works by comparing faces captured by cameras against a predetermined watchlist.

Several UK police forces are now publishing information on their deployments, including where the technology is being used and how individual deployments perform.

Essex Police, for example, has published deployment data covering locations including Southend, Clacton, Harlow and Chelmsford during summer 2026. Its published figures include the number of faces seen, alerts generated and interventions made.

Thames Valley Police has similarly published data from its 2026 deployments, showing how the technology is being used across locations including Slough, Reading and Oxford.

The growing amount of operational data is helping to make the conversation around facial recognition more tangible.

Rather than discussing the technology purely in terms of potential, organisations can increasingly examine how it performs in real-world environments.

Security and privacy

The expansion of facial recognition does not come without questions.

Biometric data is particularly sensitive, and organisations using the technology need to consider how it is collected, processed and protected.

For law enforcement, the UK Government has been considering the legal framework surrounding the use of facial recognition and other biometric technologies, with a consultation on a new framework running earlier this year.

The debate is therefore not simply about whether facial recognition works.

It is also about when it should be used, what safeguards should be in place and how organisations can maintain public confidence in its deployment.

Beyond facial recognition

The same conversation is increasingly relevant to access control.

Biometrics can provide another way of establishing identity, alongside traditional cards, mobile credentials and other authentication methods.

As access control becomes more connected, biometric technologies can also sit alongside wider security systems, including video surveillance and other monitoring technologies.

This creates opportunities for organisations to build more integrated security environments, but also means technology decisions need to be considered as part of the wider security infrastructure rather than in isolation.

What comes next?

Facial recognition is likely to remain one of the more closely watched areas of security technology as adoption grows.

The challenge for the industry will be finding the right balance between what the technology can offer and the responsibilities that come with using it.

As biometrics become more closely connected to access control and identity management, those questions will increasingly sit alongside discussions about interoperability, data and the role of technology in modern security.
