Technical surveillance counter-measures (TSCM) — systematic detection and removal of covert listening devices, hidden cameras, and unauthorised surveillance equipment.
Electronic surveillance is one of the most difficult threats to detect without specialist knowledge and equipment. Modern covert devices are small, sophisticated, and capable of transmitting audio, video, or location data from within a room, vehicle, or personal environment — often going unnoticed for extended periods.
ABR Security provides Technical Surveillance Counter-Measures (TSCM) — commonly known as bug sweeping — using professional-grade detection equipment and structured search methodologies. Every engagement is conducted by trained specialists who understand both the technology used in surveillance devices and the techniques used to conceal them.
Our counter-surveillance services are available for private residences, corporate offices, vehicles, and temporary environments such as hotel rooms or meeting spaces. Each sweep is thorough, discreet, and tailored to the specific risk profile of the client and the premises being examined.
Comprehensive TSCM engagements covering all forms of electronic surveillance — from audio bugs to covert cameras and data exfiltration devices.
Systematic physical inspection of premises — examining walls, ceilings, furniture, fixtures, and personal items for concealed devices or signs of tampering.
Radio frequency (RF) spectrum analysis and non-linear junction detection — identifying active and dormant transmitting devices across all frequency bands.
Evaluation of the surveillance risk profile — identifying vulnerabilities in the environment and recommending countermeasures to prevent future compromise.
Inspection of local networks for unauthorised devices, data exfiltration tools, and compromised endpoints — covering Wi-Fi, Bluetooth, and wired connections.
Safe removal and documentation of any discovered surveillance equipment — with full reporting on device type, capability, and likely installation method.
Ongoing counter-surveillance programmes — regular sweeps of key environments to ensure continued protection against newly introduced surveillance devices.
Counter-surveillance sweeps are appropriate in a range of situations where the risk of electronic surveillance is elevated.
