TSCM Inspection & Bug Sweep
Eavesdropping technology is smaller, cheaper and more readily available than ever. A hidden microphone fits inside a power socket, a spy camera hides in a smoke detector, a GPS tracker attaches under your bumper. TSCM stands for Technical Surveillance Countermeasures — the professional detection and neutralisation of unwanted surveillance equipment. SAJ Recherche Amsterdam conducts TSCM inspections with military-grade counter-surveillance equipment. We serve businesses, law firms, private individuals and real estate professionals throughout the Netherlands.
What we investigate
What do we detect?
Our inspection targets all forms of unwanted surveillance: hidden microphones in power sockets and furniture, GSM transmitters, pinhole and Wi-Fi cameras, IP cameras on corporate networks, GPS trackers on vehicles and in belongings, spyware on laptops and phones, compromised Wi-Fi networks, and keystroke loggers. We use military-grade detection equipment to locate every threat.
What equipment do we deploy?
We work exclusively with professional, military-grade TSCM equipment: spectrum analysis (10 kHz – 24 GHz) for radio and GSM signals, Non-Linear Junction Detection for electronics even when switched off, telephone line analysis with digital demodulation, optical camera lens detectors, pole cameras and borescopes for inaccessible spaces, and cellular activity monitors for 3G/4G/5G plus Bluetooth and Wi-Fi analysers.
Where do we conduct sweeps?
We tailor each inspection to the specific risks: offices and boardrooms where sensitive decisions are made, secretarial workspaces with access to confidential documents, common areas where sensitive conversations take place, electronic devices checked for spyware, business and private vehicles scanned for trackers, private homes in cases of stalking or divorce, and hotels or holiday rentals.
