What We Can Detect — and How We Find It
Our team uses professional-grade detection equipment to locate every category of covert surveillance device — whether it's actively transmitting, sitting dormant, hardwired, or hidden inside everyday objects.
Threats We Identify
Threats We Identify
Surveillance devices come in many forms. Some transmit constantly. Others activate on sound or motion. Some are hardwired and never broadcast at all. Our sweep protocol is designed to catch all of them.
RF & Wireless Transmitters
Hidden microphones and cameras that broadcast audio or video wirelessly. Detected via full-spectrum radio frequency sweep across all transmission bands.
Hardwired Audio & Video Devices
Listening devices that record locally and never transmit — making them invisible to basic RF detectors. Found through physical inspection and line analysis.
GSM & Cellular-Based Bugs
Devices that use cellular networks to transmit audio. These operate like phones and require specialized detection equipment to identify their signal signatures.
GPS Tracking Devices
Both active GPS trackers (transmitting in real time) and passive data loggers (storing location history). Detected through physical vehicle inspection and electronic sweep.
Covert Cameras & Optical Devices
Pinhole cameras, infrared-capable lenses, and motion-activated recording devices concealed in everyday objects — clocks, smoke detectors, power strips, and more.
Network & IT-Based Eavesdropping
Rogue Wi-Fi access points, compromised routers, and unauthorized network taps that intercept communications at the infrastructure level.
Mobile Device Spyware
Stalkerware and commercial spyware installed on smartphones that silently record calls, messages, and location data. Identified through device-level forensic analysis.
Dormant & Non-Transmitting Devices
Devices that activate only on sound, motion, or a remote trigger — and are silent the rest of the time. Caught through nonlinear junction detection and physical inspection.
Detection Equipment
Professional-Grade Detection Equipment
We use the same categories of equipment deployed in government and corporate security operations. Every sweep combines electronic detection with hands-on physical inspection — because no single tool catches everything.
Nonlinear Junction Detectors (NLJD)
Dormant & Powered-Off Devices
Identifies electronic components — including powered-off and dormant devices — by detecting semiconductor junctions inside walls, furniture, and objects.
Wideband RF Spectrum Analyzers
Full Radio Frequency Spectrum
Scans the full radio frequency spectrum to detect active wireless transmissions from hidden microphones, cameras, and tracking devices.
Thermal Imaging Cameras
Heat Signature Detection
Detects heat signatures from powered devices concealed behind walls, under flooring, or inside objects where visual inspection is not possible.
Time-Domain Reflectometers (TDR)
Wired Infrastructure Analysis
Analyzes telephone lines, network cables, and electrical wiring for unauthorized taps, splices, or listening devices connected to existing infrastructure.
Near-Field Detection Equipment
Low-Power Transmissions
Detects very low-power transmissions that evade standard RF sweeps — including devices designed specifically to avoid detection.
Optical & Physical Inspection Tools
Visual & Cavity Inspection
Borescopes, lens detectors, and illumination equipment used to physically inspect cavities, fixtures, furniture, and objects where devices are commonly concealed.

Executive Suite Sweep — Financial Services Firm
Situation
A senior partner at a financial services firm suspected a competitor had obtained advance knowledge of confidential client negotiations. The firm's legal counsel requested a sweep of the executive floor prior to a critical board meeting.
Approach
Full RF spectrum analysis of all meeting rooms and executive offices. NLJD sweep of furniture, fixtures, and installed equipment. Physical inspection of all telecommunications infrastructure and network access points.
Finding & Outcome
A GSM-based audio transmitter was located inside a power strip in the primary conference room.
Device was documented, preserved for legal proceedings, and removed. The client was briefed directly. No third parties were involved in the findings process.
Law Firm Conference Room — Privileged Communications
Situation
Outside counsel for a high-profile litigation matter requested a sweep of their conference facilities after a client reported that opposing counsel appeared to have foreknowledge of privileged strategy discussions.
Approach
Comprehensive sweep of all conference rooms and attorney offices. Line analysis of telephone and data infrastructure. Optical inspection of all installed fixtures and furnishings.
Finding & Outcome
No active devices were found. A previously unknown network tap was identified on a legacy telephone line that had not been decommissioned.
The tap was removed and the line was taken offline. The firm implemented revised physical security protocols for sensitive meetings.
Private Residence — Domestic Dispute Context
Situation
A client going through a contentious divorce believed their spouse had installed monitoring devices in the family home. The client had observed unexplained behavior suggesting their private conversations were being monitored.
Approach
Room-by-room RF sweep and NLJD inspection of the entire residence. Physical inspection of common concealment locations — smoke detectors, clocks, charging devices, and installed fixtures.
Finding & Outcome
Two devices were located: a covert audio recorder inside a bedroom clock and a GPS tracker attached to the undercarriage of the client's vehicle.
Both devices were documented and preserved. The client's legal team was provided with a formal findings report suitable for use in family court proceedings.
Fleet Vehicle Sweep — Corporate Executive
Situation
A CEO of a mid-sized company requested a sweep of their personal and company vehicles after noticing that confidential travel plans appeared to be known in advance by an unknown party.
Approach
Full physical and electronic inspection of three vehicles. GPS tracker detection sweep using both active and passive detection methods. Inspection of all accessible cavities, wheel wells, and undercarriage.
Finding & Outcome
A passive GPS data logger was found magnetically attached inside the rear wheel well of the primary company vehicle.
Device was removed and documented. The client was advised on ongoing vehicle security practices and counter-surveillance awareness.
What Every Engagement Includes
What Every Engagement Includes
Every Global Shield TSCM sweep concludes with a full written report and direct debrief. Nothing is communicated through a call center or third party — findings go directly to you.
Confidential Written Findings Report
A complete document detailing sweep methodology, all areas inspected, equipment used, and findings — suitable for legal, corporate, or insurance records.
RF Spectrum Scan Documentation
Logged spectrum analysis data confirming the scope and results of the electronic sweep.
Device Documentation & Evidence Preservation
If a device is found, it is photographed, catalogued, and preserved according to chain-of-custody standards — ready for use as evidence if legal action follows.
Remediation Recommendations
Actionable guidance on closing the security gaps identified during the sweep — including physical, procedural, and technical countermeasures.
NDA Available on Request
All engagements are treated as confidential by default. A formal non-disclosure agreement is available for clients who require it.
