Surveillance Countermeasures in Canada

Do you feel like you’re being watched? Do you have reasonable grounds to believe someone is illegally monitoring you? We provide surveillance countermeasures to give you peace of mind in family, civil and criminal matters. If you suspect that your home, office, business or car is bugged with a hidden audio, video or tracking recording device, we can carry out a discreet sweep of your location. If we find any hidden devices, we will provide you with the evidence, and if you are not being monitored, you can rest easy. Our detectors can locate all types of hidden devices, including:

  • Wireless microphones

  • Wired and wireless cameras

  • Audio transmitter bugs

  • Video transmitters

  • GPS tracking devices (when the device is transmitting a signal)

  • Wireless /transmitter bugs

  • GPS vehicle tracking devices

  • All types of concealed transmitters

  • All types of hidden video cameras

  • Computer and fax eavesdropping transmitters

  • "Series" and "parallel" telephone transmitters
