How We Conduct Operations

Evidence-Ready Procedures

If we find something, we neutralize it and preserve it correctly—photos, RF logs, chain-of-custody—so your counsel has what they need if action is required.

Discreet Arrival, Low Profile

We show up in plain clothing with unmarked cases. If you prefer after-hours or a low-traffic window, we schedule accordingly so attention stays off your location.

Confidential From First Contact

Your details stay private. We begin with a short, confidential intake to understand your space, concerns, and timeline—then propose a scope-based quote with no surprises.

Minimal Disruption to Your Day

We coordinate around meetings, family schedules, staff and guests. Furniture and fixtures are returned exactly as found; sensitive areas are handled with extra care.

What We Actually Do

A Centurion sweep is a layered examination of your environment. We begin with a confidential intake to understand who might target you and why. Then we establish an RF baseline and map live transmissions across the spectrum, hunting for anomalies others miss—burst transmissions, frequency-hopping devices, and hidden beacons that masquerade as everyday electronics.

While instruments run, we execute a meticulous physical inspection: ceilings, fixtures, outlets, furniture, décor, vents, vehicles. We open what needs opening and trace what needs tracing. We examine telecom and low-voltage wiring, verify telephone and network integrity, and use non-linear junction detection (NLJD) to locate dormant electronics—even when they’re powered off. When DVRs or recorders are in play, we follow examiner-level procedures to review, preserve, and export data appropriately.

At the end of the sweep you’ll get a same-day verbal brief and a written report within 24–72 hours: findings, photos, RF logs, wiring notes, and clear remediation steps. If we discover a device, we neutralize it and—if you’re considering legal action—preserve evidence under chain-of-custody.

Confidential intake: threat model, who/why, spaces that matter.
RF baseline & spectrum map: log live transmissions; flag anomalies (burst, hopping, hidden beacons).
Meticulous search: ceilings, fixtures, outlets, furniture, décor, vents, vehicles—open/trace as needed.
Wiring & telecom validation: inspect low-voltage runs; verify telephone and network integrity.
NLJD sweep: locate dormant/ powered-off electronics with non-linear junction detection.
DVR/media handling: examiner-level review, preservation, and exports when recorders are present.
Same-day brief: on-site summary of findings.
Written report (24–72 hrs): photos, RF logs, wiring notes, and prioritized remediation steps.
Remediation & evidence: neutralize devices; preserve under chain-of-custody if legal action is anticipated.
