Bug Sweep & TSCM Investigation
Confidential technical surveillance countermeasures for suspected listening devices, hidden cameras, trackers, and covert transmitters—investigated methodically and documented by a licensed California private investigator.
Find the exposure. Preserve the facts.
A Methodical Bug Sweep for Sensitive Spaces
A suspected listening device, hidden camera, tracker, or unauthorized transmitter creates an immediate security concern—but a hurried search can miss the threat, destroy evidence, or alert the person responsible. A professional TSCM investigation begins with the risk, the environment, and the decisions the client may need to make after the inspection.
ROHOVOT combines licensed private-investigation judgment with technical and digital-evidence discipline. We scope the inspection around the location and threat model, examine relevant radio-frequency activity, inspect likely concealment points, document findings, and identify practical steps to reduce continuing exposure.
Assess the Threat
Clarify who may have motive, opportunity, access, and technical capability; identify sensitive conversations, unusual events, and the rooms, vehicles, devices, or systems most at risk.
Inspect in Layers
Use appropriate RF analysis, physical inspection, and targeted technical checks to investigate active, intermittent, wired, concealed, and network-connected surveillance risks.
Document and Respond
Record the scope, methods, observations, limitations, and evidence-handling steps, then provide prioritized remediation and recommendations for repeat inspections or monitoring.
Do not remove or manipulate a suspected device before discussing safety, ownership, evidence preservation, and legal considerations with an appropriate professional.
What a TSCM Investigation Can Examine
The exact procedure depends on the space, access history, urgency, and suspected surveillance method. The investigation is tailored rather than reduced to a single detector or quick scan.
Radio-Frequency Environment
We assess relevant spectrum activity and investigate signals that warrant closer examination. Because legitimate offices contain Wi-Fi, Bluetooth, cellular, building systems, and other emitters, interpretation and correlation matter as much as detection.
Physical and Concealment Inspection
Likely hiding places, recently introduced objects, power sources, cabling, fixtures, furnishings, and accessible structural areas can be examined for signs of tampering or concealed equipment. The scope is agreed in advance and respects property and access limitations.
Hidden Cameras, Trackers, and Connected Devices
Depending on the assignment, the sweep may address covert video, location-tracking concerns, unauthorized wireless devices, or suspicious equipment connected to the local environment. Specialized follow-up may be recommended where access or conditions limit the initial inspection.
Evidence, Reporting, and Remediation
If suspicious equipment is located, the next step depends on safety, ownership, legal strategy, and the need to preserve evidence. We can coordinate documentation, chain of custody, forensic review, counsel, or law-enforcement referral while avoiding unnecessary handling.
Confidentiality Begins Before the Sweep
The planning conversation can itself reveal an investigation if it takes place through a compromised device or inside the location of concern. Initial contact should be made through a reasonably trusted channel and away from the suspected space whenever practical.
TSCM is most effective as part of a broader security practice. Access control, meeting procedures, device policies, network security, staff awareness, and periodic reassessment can reduce the opportunity for surveillance after the immediate inspection is complete.

A technical surveillance countermeasures investigation is a systematic inspection for covert audio, video, tracking, and data-transmission threats. It combines radio-frequency analysis, physical inspection, and other technical checks selected for the location, risk, and suspected method of surveillance.
A sweep may be appropriate before or after sensitive negotiations, executive meetings, litigation, a high-conflict separation, suspected information leakage, unexplained device activity, or unauthorized access to a private office, residence, or vehicle. The circumstances determine the lawful scope and equipment used.
No credible provider can guarantee that every possible device will be found. Some devices transmit intermittently, remain dormant, or are concealed in ways that require specialized access. We document the areas, methods, equipment, observations, limitations, and recommended follow-up so the findings are clear and defensible.
Contact us from a device and location you reasonably believe are secure, avoid discussing the planned sweep in the space of concern, and do not disturb suspected equipment. Call (310) 270-0598 to discuss the location, urgency, access, and confidentiality requirements with a licensed investigator.
