Property Inspection for Interception – Specialized Counter Surveillance Control

At Nikos Pelekasis & Associates Private Investigation Agency, we offer specialized services for the detection and neutralization of surveillance devices, also known as Technical Surveillance Counter Measures (TSCM). Modern forms of surveillance have evolved, so special equipment, experience, expertise and absolute discretion are required.

1. When is it necessary to monitor a place for eavesdropping

A business or private place can be the target of surveillance for financial, personal or political reasons. If you observe:

• Leakage of confidential information,
• Suspicious interference on telephones or electronic devices,
• Unexplained presence of people in your space or changes in the arrangement of objects,

then an immediate technical check of the space for possible surveillance with “bugs”, cameras, recorders, GSM devices or even spyware on mobile phones is recommended.

2.Property Inspection for Interception is carried out on three levels:

Α. Physical Inspection of the Premises

• Checking of places with electrical or telecommunication infrastructure (sockets, light fixtures, smoke alarms).
• Investigation of furniture and objects that can conceal devices.
• Thermography of walls and ceilings to detect hot spots (active mechanisms).

Β. Electronic Detection – The Core of Professional Counterintelligence

Electronic detection is the most technologically critical stage in the monitoring of a place for eavesdropping. Specialised equipment is used to scan radio frequencies, electromagnetic waves and electronic signals to detect active or inactive surveillance devices.

1. RF Sweep

• Detection of analogue/digital devices (VHF, UHF, GSM, LTE, Wi-Fi, Bluetooth).
• Detection of burst, sporadic, or continuous emissions.

2. Detection of GSM/3G/4G/5G Devices

• Detection of GSM bugs activated by phone call.
• Use directional antennas and cellular interceptors.

3. IP Hidden Camera Detection

• Network analysis (MAC addresses, port forwarding).
• Use Wireshark, Fing, Kismet tools.

4. Bluetooth Devices

• Detection of BLE advertising packets.
• RSSI analysis for distance estimation.

5. Ultrasound or Laser Microphone Detection

• Use ultrasound spectrum analyzers.
• Detection of fiber optic and laser-based microphones.

6. Trigger-Activated Devices

• Tests with artificial sound/motion.
• Emission recording with data loggers.

7. Non-Linear Junction Detectors (NLJD)

• Detection of circuits even without emission.
• Ideal for walls, ceilings, drawers.
• Γ. Analysis of Telecommunication Lines and Devices
• Checking landlines for line trapping.
• Check mobile phones for spyware via forensic tools.
• Analysis of SIM, VoIP, routers, cabling.

3. Machines and Technological Equipment Available

Our office uses certified professional monitoring equipment:

• RF Spectrum Analyzers: analog/digital frequencies up to 12 GHz.
• Non-Linear Junction Detectors (NLJD).
• Thermal Imagers: Thermal cameras for detecting active machines.
• TDR – Time Domain Reflectometer: Analysis of telephone lines.
• Spyware Forensics Kit: Detection of mobile spyware.
• Audio Frequency Detectors: Detection of ultrasonic audio transmissions.

4. Phone Testing (Mobile & Fixed)

We perform complete analysis of telephone devices:

• Mobile: Spyware detection (Pegasus, FlexiSpy, Cerberus).
• Fixed: Line analysis for illegal interference.
• Checking VoIP, routers, SIM, applications, cables.

5. Final Report – Use in Court

If a tracking device is detected:

• We compile a full technical report with photographic evidence, technical characteristics, risk assessment and recommended actions.
• The report is signed by a qualified technician and can be used as evidence in court proceedings.
