GSM and GPS tracker detection
Trackers are not limited to vehicles. Bags, coats, children's toys and gifted items can also be used.
Types of trackers
GSM-based devices are small units that send location and sometimes audio using a SIM card. GPS loggers store location in their own memory to be collected later; as they do not transmit they may not appear in an RF sweep. Bluetooth trackers (tag-type devices) report location through nearby phones.
Bluetooth trackers
Modern phones can warn you when they notice a tracker that is not yours moving with you. We recommend keeping these alerts on. If you receive one, find and photograph the device and follow the relevant steps; if unsure, ask for a professional check.

How we work
Confidential initial call
We talk on a secure channel away from the space and devices you suspect. We listen to what, where and why you suspect, and define the scope.
Appointment and security
The sweep date is discussed only with the people who need to know and away from the space to be swept. No sensitive talk takes place in the space beforehand.
Physical inspection
The space and its items are inspected visually: sockets, ceiling, lighting, electronics, furniture and newly added objects.
Technical sweep
Devices are searched for with RF spectrum analysis, NLJD, thermal imaging, optical lens detection and line/network analysis.
Findings and evidence preservation
If a suspect device is found it is not moved; it is photographed and its position and technical measurements recorded. The next step is decided with you and your lawyer.
Report and recommendations
Method, equipment, findings, risks and corrective recommendations are delivered as a written report.
