Electronic Bug Sweep (TSCM)
An electronic room sweep (TSCM) is the complete technical inspection of meeting rooms, offices and residences to locate bugs, hidden cameras, transmitters and any surveillance device — powered or unpowered. For 18 years, SCS Detect has delivered international-standard sweeps across Brazil.
In short
SCS Detect's electronic sweep (TSCM) finds bugs, hidden cameras, wiretaps and transmitters in meeting rooms, offices and residences — even when powered off. We use RF spectrum analysis, non-linear junction detection (NLJD) and thermography, delivering a technical report with response within 4 hours. 18 years across São Paulo, Rio and Brasília.

Non-linear junction detection — NLJD (REI ORION 2.4): finds electronics even when off
Thermography with FLIR cameras: reveals powered devices behind surfaces
Meticulous physical sweep with controlled disassembly of critical points
Executive report + detailed technical/forensic report + vulnerability analysis
When should you order a sweep?
Before strategic meetings, M&A negotiations, shareholder disputes or sensitive hearings; after critical dismissals, renovations or third-party access to the environment; or whenever an information leak is suspected. Highly sensitive environments benefit from scheduled periodic sweeps.
What you receive
You receive a clear executive report for decision-making and a detailed technical report with evidence and measurements. If a device is found, we produce full forensic documentation — photos, location and identification — plus an environment vulnerability analysis with hardening recommendations.
How long does a room sweep take?
It depends on the size and criticality of the environment. A meeting room typically takes 2 to 4 hours; a corporate floor or a residence, a full day. We work with reserved scheduling and, when needed, outside business hours to preserve discretion.
Does the sweep find powered-off devices?
Yes. Beyond radiofrequency analysis (which detects active transmitters), we use non-linear junction detection (NLJD), which identifies electronic components even without power, and thermography, which reveals powered devices behind surfaces. It is the combination of these techniques that ensures full coverage.
