Frequently asked questions
Is it legal to deploy counter-drone technology in the UK?
Detection is legal. Jamming, spoofing or physically interfering with drones is not, unless conducted by authorised agencies under specific legislation. Image Surveys operates strictly within UK law and briefs all clients on the legal framework before any deployment.
What does Martyn's Law require for drone security?
The Terrorism Protection of Premises Act 2025 (Martyn's Law) requires Enhanced Tier venues to conduct vulnerability assessments. Drone threat is a recognised component of a modern venue security review — our counter-drone risk assessment and aerial site survey provide the documented evidence a security adviser needs to address this element of the assessment.
Can you integrate with an existing security operation?
Yes. We work alongside existing security teams and can provide briefings, equipment and technical support that complement current protocols and command structures. Our involvement can be managed discreetly where required.
Do you work with prisons and secure facilities?
Yes. Prisons are among the most common sites for unauthorised drone activity. We are familiar with the legal and operational constraints around secure facilities and manage our engagement accordingly.
