Our Technical Surveillance capability provides clients with discreet, covert monitoring solutions that are ethically planned, legally compliant, and executed to the highest standards. Led by Home Office-qualified Technical Surveillance Officers, each deployment is tailored to meet specific operational objectives while maintaining the integrity and legality of the operation.

Discreet Covert Monitoring Solutions

We specialise in the full lifecycle of technical surveillance deployments — from initial planning and reconnaissance, to the design and construction of bespoke hides, through to the precise installation, remote monitoring, and final recovery of the device. Every element is meticulously considered: sightlines, concealment, power management, signal integrity, evidential continuity, and environmental factors.

Our approach is founded on operational discipline, due diligence, and an in-depth understanding of surveillance law and procedure. With a proven track record supporting law firms, corporate security departments, and private clients, our technical teams deliver high-quality intelligence without compromise — ensuring the right information is obtained, safely and securely.

24/7 Technical Surveillance Capabilities

This service is ideal for:

  • Long-term monitoring of static locations where physical presence is not viable

  • High-risk environments where low-profile observation is essential

  • Supplementing physical surveillance teams with a 24/7 technical overwatch capability

  • Situations requiring covert audio-visual evidence gathering to support legal or corporate investigations
