When a wiretap sweep is needed

Detection of wiretaps and surveillance devices becomes important when there are signs of an information leak, or when an inspected object has recently been accessible to people outside your trusted circle.

  • Unknown people had access to the room or vehicle
  • The office, apartment or vehicle was recently repaired or serviced
  • Competitors or third parties know details of confidential negotiations or private conversations
  • There are signs of a business, financial or personal data leak
  • An important meeting, transaction or strategy session is coming up

Vehicle wiretap detection

A vehicle is one of the most vulnerable places for confidential conversations. Tracking and listening devices can be hidden in areas that are difficult to inspect without specialized equipment.

A vehicle bug sweep covers the cabin, trunk, wheel arches, engine bay and wiring. The inspection can reveal both active devices and powered-off devices that activate only while the vehicle is moving.

  • GPS trackers and radio beacons used to monitor location
  • Radio microphones and GSM bugs used to listen to conversations inside the cabin
  • Hidden cameras and voice recorders with remote activation
  • Devices operating over Bluetooth, Wi-Fi and cellular networks

Office, apartment and home sweeps

Office wiretap protection is essential for companies working with confidential information. Home and apartment checks are also relevant after repairs, rental moves or visits by unknown people.

The inspection covers all room zones, including furniture, office equipment, sockets, ventilation grilles, decor items and lighting fixtures.

  • Radio microphones, GSM bugs and DECT transmitters
  • Hidden cameras, including pin-hole lenses
  • Devices using power lines, telephone lines and security alarm wiring
  • Transmitters operating over Wi-Fi, Bluetooth and infrared channels
  • Digital voice recorders and offline recording devices
