Our use of electronic surveillance detection can give you confidence that your privacy is protected at your residence or office space. There are many reasons to suspect illegal surveillance. Many people have discovered bugs in phones, cameras planted in homes, GPS Tracking devices found in vehicles, and recording devices found in personal offices.

If you value your privacy at work or your home and suspect the presence of bugs, recording devices, hidden cameras, or GPS Tracking devices, the most effective option is to hire a private investigator to perform counter-surveillance and to find these bugs evading your privacy.
