Highest-Grade TSCM Equipment to detect all technical surveillance threats


Spectrum Analysis & Full Demodulation with Highest-Grade TSCM Technology to Combat Emerging Threats

TSCM America utilizes the highest-grade of TSCM equipment and processes to combat the emerging threat and more importantly the detection and discovery of technical eavesdropping devices. These real threats come from all forms of transmitters whether concealed, covert, or overt. Technology is ever changing with Bluetooth, WI-FI, and with the “Internet of Things” IOT. Our company has the technical TSCM equipment, TSCM training, years of experience, and skilled TSCM Operators needed to ensure and protect your privacy.


TSCM Technology

TSCM America only uses the highest-grade TSCM equipment and technology to protect your privacy and communications:

  • Broadband RF Receivers
  • Carrier Current Analyzers
  • Thermal Imaging Technologies
  • IR Detection
  • Non-Linear Junction Detectors
  • Wi-Fi Analyzers
  • Visible Light Detection
  • Ultra-Sonic Analysis
  • Telecommunication Analysis

Proactive Measures

TSCM Equipment

Taking a proactive approach to protecting your communications and privacy is critical in a world of others stealing your information.  Tens of billions of dollars are lost annually to industrial and economic espionage.

Many clients have told us that they in the past, had a reactive approach towards communication privacy, meaning all is good until sensitive information surfaced that only could have been heard through technical eavesdropping.  TSCM America is a proactive company to protect and safeguard our client’s privacy.

Evaluating your Risk is Vital to Maintaining your Business and Personal Privacy, Security and Peace of Mind, and the Risk of Electronic Eavesdropping

Technology is the Key!

High-grade or often times referred to government grade technical spectrum analyzers that have the ability to receive and capture “free space” RF frequency transmissions and allow the technician to demodulate each signal. This allows for RF signal detection and identification of real-time frequency analysis.

All frequencies are analyzed and determined to be friendly or a potential threat such as open audio, video, cellular, or other transmissions that can be identified and located. The RF spectrum must be analyzed with a spectrum analyzer capable of covering a wide range of the frequency spectrum. Our equipment is capable of detecting carrier current devices on power lines as well as demodulation sub-carrier transmissions. Sophisticated techniques such as frequency hopping, spread spectrum, and video transmissions are only possible to detect and demodulate with a government grade spectrum analyzer.

Additional functions include RF signal capture and RF mapping that is useful on return visits to use as baselines to spot immediate threats.

Cutting-Edge Technology

TSCM America applies many different technologies within each project to ensure the threat is detected. They include:

  • Broadband RF Receivers
  • Non-Linear Junction Detection
  • Wi-Fi Analyzers
  • Carrier Current Analyzers
  • Ultra-Sonic Detection
  • Thermal Imaging Technologies
  • IR Detection
  • Visible Light Detection
  • Laser and Microwave Detection
  • Telecommunication and AV Analysis

Threat Identification

A Non-Linear Junction Detector (NLJD) is technically a microwave transmitter and receiver, designed to detect all transistors, diodes and other semiconductor devices which are found in transmitters, tape recorders, microphones, electronics, and other eavesdropping devices. The NLJD is the only type of instrumentation that can successfully detect all radio transmitters, regardless of their transmission frequency, even if the devices are powered off.

Without the NLJD, the TSCM service would be unable to detect tape recorders, hidden microphones, remotely controlled transmitters, ultrasonic, infrared or microwave transmitters and other hidden devices which may be embedded in the walls, ceilings, or furniture and possibly beyond the detection capability of other test equipment. TSCM America uses these devices as part of our inspection process.

- Financial Corporation, Dallas Texas

Great Work!

We are a mid-size advertising corporation that felt confident that our conference room had some sort of listening device planted within the room. We contacted TSCM America to sweep the offices and sure enough they located a small radio audio devices about the size of a quarter in a plant next to the table. Great work and fast response!

- David C, President, Saint Louis, Mo.

Thank you!

I'm impressed with your company as well as your ability to provide the means / skills needed to resolve the issue.  We reviewed your Better Business Bureau reputation and found all 5 star reviews.   Again, many thanks!
