MSI Detective Services provides bug sweeps and electronic countermeasures for offices, homes and vehicles in Chicago. These inspections are often called technical surveillance countermeasures, or TSCM, and address concerns about hidden listening devices, cameras and tracking equipment.
We begin by discussing what prompted your concern, the spaces or equipment involved and the questions you want answered. The inspection is planned around the circumstances and the areas you authorize us to examine.
What a Bug Sweep May Cover
- Physical inspection of premises for concealed microphones, recording devices and hidden cameras.
- Radio frequency testing for signals that may warrant further examination.
- Telephone instruments, telephone systems and line integrity checks.
- Evaluation of wiring, including telephone, electrical, cable and network wiring.
- Vehicle inspections for GPS trackers and GPS logging devices.
- Security evaluations and recommendations based on the findings.
The appropriate tests depend on the location, equipment and suspected activity. We explain the inspection scope and findings; the absence of a detected device does not establish that every possible form of surveillance has been ruled out.
Phone and Computer Privacy Concerns
A premises sweep and a digital device examination address different questions. If your concern involves a smartphone, ask about cell phone forensics and cellular data recovery. Computer related concerns may call for computer forensic services, including examination for spyware or other unwanted software.
Tell us which devices you own or are authorized to provide for examination so we can discuss the relevant services.
Specialized Inspection Equipment
MSI uses specialized tools such as non-linear junction detectors, spectrum analyzers, time domain reflectometers, radio frequency detectors, camera lens detectors and telephone analyzers. Physical inspection and technical testing work together to examine potential concerns.
