Counter-Surveillance Services Across Massachusetts
Counter-surveillance (also called TSCM, or technical surveillance countermeasures) finds out whether someone is being watched, followed, or electronically monitored, and removes the threat once it’s confirmed. Clients come to us after noticing the same vehicle too many times, suspecting a hidden camera or audio device in a home or office, or simply wanting a professional sweep before a sensitive meeting or move.
A sweep covers both the physical and the electronic: a hands-on inspection of likely hiding spots (vents, fixtures, smoke detectors, vehicles) alongside RF (radio-frequency) detection equipment that can flag an active transmitting device. If we find something, we document it, and if the situation points to stalking or harassment rather than a one-off privacy breach, we’ll say so plainly and talk through reporting it to police.
- ✓Physical inspection of a home, office, or vehicle for hidden cameras, audio devices, or GPS trackers
- ✓RF spectrum detection equipment to identify active wireless transmission
- ✓A written report of everything found — or a clear, documented all-clear if nothing is
- ✓Surveillance-detection guidance if you suspect you’re being followed, not just recorded
- ✓Honest direction on when a finding should go to law enforcement instead of staying a private matter
What a Sweep Actually Finds
Most sweeps turn up nothing, and that’s a genuinely useful result — peace of mind backed by a real inspection, not just a feeling. When we do find something, it’s most often a GPS tracker on a vehicle or a hidden camera in a shared or recently-vacated space. We document the device, its location, and when it was found, which matters if the discovery later becomes part of a restraining order petition or police report.

Common Questions
Is it legal for someone to have put a hidden camera in my space? It depends heavily on the location and relationship — a landlord hiding a camera in a tenant’s bathroom is a different legal situation than a roommate’s shared living room. We can tell you what we found; whether it was lawfully placed is often a question for an attorney or the police.
Can you tell if my phone is being tracked? We can walk through the signs and check settings with you, but phone-level spyware detection is a different, more specialized discipline than a physical/RF sweep — we’ll tell you honestly if that’s the better next step.
Counter-surveillance work is conducted under the same Massachusetts private investigator licensing requirements as our other investigative services, and the deliverable reflects that: a documented account of what was observed during the detection sweep, not just a verbal assurance that “everything looked fine.”
What a Hub Counter-Surveillance Report Looks Like
Below is a shortened, fictional sample report in the same format our investigators deliver.
HUB SECURITY AND INVESTIGATIVE GROUP
Counter-Surveillance Report — Sample (Fictional)
Case #: SAMPLE-5027 Date: 03/02/2026 Investigator: K. Novak
Summary of Findings: A detection route was run over a two-hour window covering the client’s normal commute and a secondary stop. No repeat vehicles, foot followers, or GPS anomalies were identified. One parked vehicle flagged during the initial pass was independently confirmed as registered to a resident of the area and ruled out as a concern.
Recommendation: No further action required at this time; client advised to request a follow-up sweep if circumstances change.

A clean result still gets a full written record — what was checked, when, and how each lead was ruled out.
