1. Radio frequency (RF) detection: RF detectors are devices that detect radio signals emitted by surveillance devices, such as hidden cameras and listening devices. These devices can help locate hidden cameras or listening devices by detecting the signals they emit.

2. Physical inspections: The Private Investigation may conduct a physical inspection of the area to look for signs of tampering or unusual devices. For example, they may inspect furniture, walls, and other fixtures for hidden compartments or holes that could conceal a camera or listening device.

3. Thermal imaging: Thermal imaging cameras can detect heat signatures from hidden devices that may be emitting heat. This technique can help locate hidden devices that may be hard to detect by other means.

Non-linear junction detection: This is a technique that involves using a device that sends out a radio signal and measures the reflections that come back. It can help detect hidden cameras, microphones, and other electronic devices that may be emitting electromagnetic signals.

4. Visual inspection: Our Private investigators may use their own eyes to look for cameras, listening devices, or other surveillance equipment. They may look for unusual or out-of-place objects, wires, or other signs that something is not right.
