Request a Confidential SweepIf you've ever felt like someone was listening — in your home, your office, your car, or your conference room — you are not overreacting. Electronic surveillance devices are more accessible, more concealable, and more sophisticated than at any point in history. A microphone the size of a coat button. A camera lens hidden inside a wall outlet. A GPS tracker tucked beneath your rear bumper with a magnetic mount. These are not hypothetical threats. They are documented realities that Empire Investigation LLC has encountered and neutralized for clients across Pittsburgh and Western Pennsylvania for over four decades.
Technical Surveillance Countermeasures — TSCM — is the professional discipline of detecting, identifying, and documenting unauthorized surveillance equipment. This is not a job for a consumer detector purchased online. Consumer-grade RF detectors generate false positives from Bluetooth speakers and baby monitors while completely missing hardwired, passive, or frequency-hopping devices. Professional TSCM requires calibrated spectrum analyzers, non-linear junction detectors (NLJDs), thermal imaging, physical search protocols, and — critically — an investigator who knows what they're looking for.
Empire Investigation LLC has been conducting professional TSCM sweeps since 1982. Our investigators have swept residential properties during contentious divorces, executive offices before sensitive negotiations, courtrooms, board rooms, hotel suites, dormitories, and vehicles. We've worked alongside attorneys, HR departments, domestic abuse advocates, law enforcement, and Fortune 500 security teams. And our founder didn't just practice the craft — he taught it, conducting annual seminars in Extreme Surveillance techniques for field surveillance professionals at the Surveillance Expo, in collaboration with G. Gordon Liddy.
Every sweep is conducted with complete discretion. We arrive in unmarked vehicles. We document everything we find — or confirm the absence of devices — with a written report suitable for legal proceedings. Whether you're concerned about a vindictive ex-partner, a corporate competitor, or simply need peace of mind before a critical meeting, Empire Investigation's TSCM team brings the equipment and experience to give you a definitive answer.

Overview
What is Technical Surveillance Counter Measures (TSCM)?
Technical Surveillance Counter Measures (TSCM), commonly referred to as bug sweeping, is the process of detecting, identifying, and neutralizing hidden surveillance devices.
These threats may include concealed cameras, hidden microphones, GPS tracking devices, or wireless transmitters operating within a property or vehicle.
Modern surveillance equipment is often extremely small, inexpensive, and difficult to detect without specialized tools. Professional TSCM services use advanced detection methods to locate these devices and ensure environments are secure.
Trainer at the Surveillance Expo
We didn't just learn counter-surveillance. We trained the surveillance industry.
For years, Empire Investigation's founder conducted annual seminars and training sessions for field surveillance professionals at the Surveillance Expo — teaching Extreme Surveillance techniques using cutting-edge technology, in collaboration with G. Gordon Liddy.
Every technique taught in those rooms is a technique we now detect. When you hire Empire for a TSCM sweep, you're not hiring the student — you're hiring the instructor.

Seminar Curriculum
Camouflage Proficiency
Successful hidden camera operation under a variety of environmental conditions — the same concealment craft we now hunt for in your walls, fixtures, and furnishings.
Using Common Tools to Accomplish Your Goals
Known on the expo floor as “The MacGyver Seminar.” Everyday objects become surveillance platforms — which is why our sweeps never trust an object just because it looks ordinary.
How to Hide a GPS in Less Than 30 Seconds
Taught at a time when government agencies were averaging eight hours per GPS installation. If a tracker can go on your vehicle in half a minute, your sweep needs to assume it did.
Selecting the Right Equipment for the Job
Shared expertise across the full breadth of innovative and novel surveillance equipment on the market — knowledge that now drives what our detection gear is calibrated to find.
Re-Engineering Equipment to Serve Any Purpose
Specialist instruction in reverse engineering and creating fresh, unique functions for any high-tech apparatus. Devices rarely look like devices. We know, because we taught that.
Warning Signs
Signs You May Need a TSCM Sweep
You hear unusual interference or unexplained noises on calls
Sensitive information is being leaked or anticipated
You notice unfamiliar devices, wiring, or changes in your environment
Your vehicle or property has been accessed without explanation
You are involved in legal, corporate, or high-risk personal situations
You suspect surveillance but cannot confirm it
If something feels off, it's worth verifying with professionals trained to detect what others miss.

Corporate Espionage Part II: How secure are cell phones?
By Robert M. Kresson · Vision — Global Business & Pleasure Magazine · 2003 · Pages 28–30
Long before smartphones, Empire Investigation's founder was warning executives in print that the phone in their pocket was the easiest listening device to plant. The feature walks through cell phone interception, GSM code-cracking, GPS location tracking, and handsets silently reprogrammed to auto-answer as room bugs.
“Plain and simple, that cell phone has become an inexpensive and practical means of espionage.”
Robert M. Kresson, Vision Magazine
Two decades later, the threats in this article are standard fixtures of our TSCM sweeps — and the reason we inspect every phone, line, and network we're asked to trust. Flip through the original pages.

Questions
TSCM & Bug Sweep FAQs
Is my house bugged?
It may be — and it's more common than most people realize. Covert listening devices are inexpensive, widely available online, and easy to conceal. The most reliable way to know for certain is a professional TSCM sweep using calibrated RF spectrum analyzers and physical inspection. Signs to watch for include: unexplained clicking or static on phone calls, smoke detectors or outlets that seem slightly off-center, a partner or ex who seems to know things they shouldn't, or your car being followed. Call Empire Investigation for a confidential consultation.
How do I know if my office is being bugged?
Common indicators include competitors knowing details of private meetings, employees acting unusually, or unfamiliar items appearing in your office. Technically, RF spectrum scanning and physical sweep are the only definitive ways to confirm or rule out surveillance. Empire Investigation conducts professional office bug sweeps in Pittsburgh and throughout Western PA with no disruption to your business.
Can I just buy a bug detector on Amazon and sweep my own house?
Consumer bug detectors sold online detect basic RF transmitters but miss a wide range of real-world surveillance devices: hardwired microphones with no RF signal, passive recording devices (no transmission at all), frequency-hopping transmitters that evade fixed-frequency scanners, and cameras hidden in objects with no wireless component. A professional TSCM sweep uses instruments costing tens of thousands of dollars and trained operators who know how to interpret results. Consumer devices provide a false sense of security.
How much does a bug sweep cost in Pittsburgh?
Cost varies by property size, number of rooms, and scope of sweep (audio, video, GPS, telephone). Contact Empire Investigation at (800) 860-6068 for a confidential quote. Most residential sweeps are completed in a single visit.
Is it legal to hire a TSCM company to sweep my home or office?
Yes, completely legal. You have every right to detect and document surveillance devices on property you own or occupy. Empire Investigation operates fully within Pennsylvania and federal law. If illegal surveillance devices are found, we can document them for law enforcement referral or civil legal action.
What happens if you find a bug in my house?
We photograph and document the device, preserve it as evidence if desired, and provide a written report detailing what was found, where it was located, and its technical characteristics. We do not remove devices until you decide — sometimes leaving a device in place while working with law enforcement or an attorney is strategically better. We guide you through your options.
How long does a bug sweep take?
A typical residential sweep of a 2,000–3,000 sq ft home takes 3–5 hours. Larger properties, offices, or vehicles add time. We schedule around your availability and arrive discreetly.
Do you sweep vehicles for GPS trackers in Pittsburgh?
Yes. Vehicle GPS sweeps are one of our most requested services, particularly in divorce and domestic abuse cases. We physically inspect the undercarriage, wheel wells, bumpers, and interior for both magnetic and hardwired trackers. Same-day service is often available. Call (800) 860-6068.
