TSCM Bug Sweeps in San Francisco, CA

The assignment starts with a baseline. Before anything is judged, the team inventories every legitimate emitter in the room: access points and their addresses, cordless handsets, wireless microphones, conferencing equipment, life-safety and access-control emitters, printers, and the client's own recording devices. An instrument can only flag what it is not expecting, so the baseline is what makes an unaccounted signal visible instead of buried in ambient traffic.

Rooms are then examined against that baseline. Walls, ceilings, vents, lighting, furniture and floor boxes are inspected physically; cabling and telecom infrastructure are traced, because a spare pair or a rogue drop is a pathway that carries audio without transmitting anything a radio survey would hear; and the network is checked for equipment that does not belong to the client's own inventory.

Where the survey covers boardrooms and executive floors, law firm conference suites, venture and growth-stage headquarters, hardware and life science facilities, the method adapts to the asset rather than the reverse. A boardroom carries structured cabling, conferencing and building systems to reconcile; a residence carries smart-home controllers and a long history of trades access; a vehicle or a yacht carries aftermarket wiring, telematics and satellite equipment that has to be separated from what the manufacturer installed.

Findings are physical facts, not impressions. A candidate signal is located, then verified by hand before it is called anything, and each finding is photographed in place, described, and given a disposition. A signal the team cannot resolve is reported as unresolved, with what would be needed to resolve it — an honest gap is more useful to a general counsel than a confident guess.

The legal boundary is fixed before the team arrives. Detection, location and documentation are the work; the content of a conversation is never captured and a device that is found is never operated. That distinction is what keeps a defensive survey lawful under the federal Wiretap Act, and it is reinforced by California Penal Code § 632, which governs how the assignment is scoped and how a recovered device is handled.

Nothing is removed informally. Possession of equipment primarily useful for surreptitious interception is itself an offence under federal law, so a device is photographed and recorded in place, its position and power state documented without alteration, and a chain of custody opened. Whether it is preserved, surrendered to law enforcement or left in place under observation is a decision for the client and its counsel, made with the survey team's factual record in hand.

Discretion is operational, not decorative. Teams arrive in plain vehicles and street clothes, without signage or uniforms, and work room by room so no equipment is staged in a lobby or a driveway. On an occupied floor the visit is scheduled around the people who would learn from watching it happen, which in practice means an evening, an early morning or a weekend, and the findings go only to the client's named recipient.

Scheduling follows the client's calendar rather than a renewal date. The highest-yield triggers are a sensitive meeting or negotiation, a merger, financing or litigation milestone, a renovation, an AV or IT installation, a change of executive assistant, house manager or facilities vendor, a residential move or a new acquisition, an unexplained leak, and any threat picture that includes surveillance.

A single survey is a point-in-time examination, and the report says so in plain language. It cannot certify a room as free of surveillance, it does not address collection on a phone or laptop, lawful interception by a carrier or a compromised account, and it does not substitute for access control. When the examination shows the exposure is a control that keeps failing, the report names that instead of recommending another sweep.

The deliverable is a written report a non-specialist can act on: scope in plain language, the baseline recorded room by room, the examination record for walls, ceilings, cabling, telecom, network equipment, furniture and vehicles, findings with photographs and dispositions, recommendations limited to what the survey supports, and the limitations stated as plainly as the findings.

Recommendations stay inside the survey's evidence and outside the provider's inventory. A physical change, a cabling remediation, an access-control correction or a repeat examination is a recommendation; hardware the team also sells is not, and no USPA survey report has ever ended in a device quotation. That independence is what makes the document usable by an insurer, a board or a court.

In San Francisco Bay Area the practical question is usually timing rather than method. A board meeting, a closing or a family event sets the date, and the survey has to fit before it: a single room the evening before, a residential arrival swept on the day, a vehicle inspected while the principal is in a meeting. Scope and price follow the spaces and the window, not a fixed package.

Coverage is staffed by personnel who work these assignments as a discipline, briefed on the property before they arrive and bound by a confidentiality agreement signed before the first room is opened. Where a client needs the findings shared with counsel, an insurer or a facility security officer, the report is issued in a form that can be circulated without exposing the client's own security detail.
