Meeting Room Sweeps (TSCM)
Clear the room before the conversation starts.Security Observed.
Technical surveillance countermeasures (TSCM) for boardrooms, conference rooms, and executive offices. Experienced sweep specialists find hidden audio, video, and wireless devices; Noble manages the engagement and fixes the network and physical gaps they uncover.
An OpenAI engineer was charged this month after a $14 listening device was found in the company’s executive conference room.
What it means for your meeting rooms →Your most sensitive conversations happen in a handful of rooms.
Product roadmaps, financing, acquisitions, and personnel decisions are discussed around the same tables every week. Those rooms are also full of microphones, cameras, and network gear, which makes a planted device easy to hide.
Planted devices
Audio transmitters, cellular bugs, and pinhole cameras now cost a few dollars and can hide in a power strip, a ceiling tile, or a phone charger.
Compromised AV
Conference bars, room cameras, and ceiling microphones can be misconfigured or tampered with to stream a meeting somewhere it shouldn’t go.
Network side doors
Rogue Wi-Fi access points and unknown devices on a meeting room’s network drop can record or relay traffic.
Physical access
Cleaners, contractors, and visitors pass through these rooms after hours. Access logs and camera coverage decide whether anyone can tell.
Sweeps scoped to the rooms that matter
Most engagements cover a defined set of rooms on one or more floors. We agree the list with you before anyone arrives.
Boardrooms and executive conference rooms
Full physical and electronic inspection of the room, adjoining walls, ceiling space, and furniture.
Video conference rooms
Inspection of displays, conference bars, room cameras, and microphones, plus a check of how that hardware is connected.
Executive offices
C-suite and leadership offices, including desk phones, chargers, and anything plugged in near where calls are taken.
Pre-meeting sweeps
A sweep timed right before a board meeting, earnings discussion, or deal review, with the room secured until it starts.
Live RF monitoring
After the sweep, a technician can monitor the radio spectrum from a nearby room during the meeting and alert your point of contact to new signals. Available depending on location and lead time.
Off-site and event spaces
Hotel meeting rooms and rented spaces swept before leadership off-sites and planning sessions.
Residential sweeps
Homes and home offices for executives and their families, scoped by the square footage to be inspected.
More than a hunt for obvious bugs
A thorough inspection combines electronic detection with a hands-on physical search and a look at the room’s network and AV systems.

From first call to a cleared room
Every engagement follows the same five steps, so your security and facilities teams know what to expect.
Confidential scoping
We agree the rooms, timing, and a single point of contact. Discuss the engagement only from a phone and location outside the rooms being swept.
RF baseline
Specialists record the room’s normal radio environment so anything unexpected stands out.
Physical and technical inspection
Hands-on search of the room, furniture, and fixtures, plus checks of AV hardware, network ports, and Wi-Fi.
Findings report
A written report of what was inspected, what was found, and recommended fixes, reviewed with you in person.
Remediation and schedule
Noble closes the network, access, and camera gaps, and sets up a recurring sweep schedule if you want one.
One accountable team, from sweep to fix
Experienced sweep specialists
Inspections are performed by experienced TSCM professionals with professional-grade detection equipment. Licensing and credentials are available on request. Noble manages scheduling, access, and reporting.
We fix what the sweep finds
Noble designs and installs access control, video surveillance, and managed networks. When a sweep turns up a rogue access point or a blind spot at a door, the same team closes it.
Scheduled around your work
Sweeps run evenings and weekends so meeting rooms stay available during business hours.
Discretion by default
We sign your NDA before scoping, arrive without branded vehicles, and share findings only with the contacts you name.
How often to sweep
One-time sweep
Any timeA full inspection of your chosen rooms with a findings report. A good starting point, and the right call if you suspect a problem.
Recurring program
Quarterly or twice a yearScheduled sweeps compared against the last RF baseline, so changes in the room are easy to spot. Recommended for boardrooms and executive floors.
Event sweep
Before key meetingsA sweep timed before board meetings, financing and deal discussions, and leadership off-sites. Live monitoring during the meeting is available depending on location and lead time.
Frequently asked questions
What is TSCM?
Technical surveillance countermeasures is the professional term for a bug sweep: a planned inspection of a space to find hidden listening devices, cameras, trackers, and wireless transmitters, and to identify weaknesses that would let someone plant one.
Will employees know a sweep is happening?
Only if you want them to. We schedule outside business hours, arrive in plain clothes without branded vehicles, and coordinate building access through your single point of contact.
What happens if you find a device?
The team documents it and leaves it in place, then contacts your point of contact immediately. You decide the next step with your security and legal teams, whether that is removal, further investigation, or involving law enforcement.
How long does a sweep take?
It depends on the number and size of the rooms and how much AV and network equipment they contain. We give you a time estimate during scoping.
Who performs the sweeps?
Experienced TSCM specialists working with Noble. Licensing and credentials are available on request. Noble is your single point of contact for scheduling, access, reporting, and any remediation work that follows.
How should we contact you about a suspected problem?
Call from a phone and location outside the area you are concerned about, and avoid discussing the sweep inside it. If you think a room is compromised, keep using it normally until the sweep so you don’t alert whoever placed the device.
