Spying might make you think of James Bond movies or the CIA… however many don’t realize, it’s become a larger part of the corporate industry and private sector. Companies of all types are spying on each other…not always to steal trade secrets, sometimes to just gain a competitive edge. Corporate espionage can not only be a security issue, but a grave corporate killer! You may not see yourself as a target, but if you’re perceived as wealthy or a person of interest, ‘someone’ (competitor, disgruntled lover, an ambitious employee, etc.) will make you a target. Without providing protection against a possible threat, you might find that new idea or invention part of a competitor’s product line. If you’re a person of importance, or happen to work with sensitive items, someone might also try to blackmail you.
Within this article, I’ll discuss the various methods used for eavesdropping and what equipment and services are needed to conduct a thorough TSCM Sweep. When hiring a TSCM company, vett them thoroughly and make sure they follow basic TSCM protocols.

There has always been a need for spying…the ‘need to know’ what someone else was doing is a basic human trait. The sophistication of eavesdropping has changed dramatically… as we move away from the ‘cup against the wall’ and towards laser listening devices and high spectrum frequency hopping, the basics and principles still remain. First off, you might be asking yourself…what does TSCM mean? If you’re searching for a company to conduct a debugging or were researching the topic, you most likely came across the term, TSCM. Technical Surveillance Counter Measures (TSCM) is the science of looking for eavesdropping equipment. On the other hand, a technical surveillance device (TSD) is an item designed to intercept communication or conversations, more commonly known as bugs. There are many countries that illegally import eavesdropping and bugging equipment into the United States, such as France, Germany, Lebanon, Italy, Canada, Israeli, England, Japan, Taiwan, South Africa…etc.
The U.S. Department of State (referenced in 1997) estimates 6,550 corporate eavesdropping incidents take place each year and approximately 888 million dollars of illegal eavesdropping equipment is imported into the United States each year. Compared to the losses… it’s unconceivable, costing corporate America closer to 800+ billion per year! The FBI and other federal law enforcement agencies have openly stated they lack the resources and training to enforce and investigate technical countermeasures (bugging).
Eavesdropping equipment can be hardwired or wireless, most commonly radio frequency (Hz, Mhz, Ghz, etc.). Eavesdropping can be conducted by leaving a device behind to gain Intel, however many newer devices can be remotely activated. Listening devices can also be hidden or disguised within ordinary products, making them difficult to locate, e.g. alarm clocks, smoke detectors, etc. Depending on the sophistication, some culprits will use existing devices and/or technology to listen in and gather Intel, e.g. (Telephone Wiring, Cellular GSM, Cable TV, Wi-Fi, Bluetooth, and even AC circuitry). Today with phones and TV’s acting more like computers… you also have to search for computer viruses.
A well-planned virus could turn your laptop mic/webcam into a listening device or turn your mobile phone into a power mic. You could enter a boardroom without knowing your sharing trade secrets with a competitor. Knowledge is POWER, be informed so you’re protected!
If you are concerned about eavesdropping taking place, I implore you to take it seriously and contact our offices or a TSCM specialist you trust and have vetted. NOT FROM THE LOCATION IN QUESTION! Do not call from your cellular phone, it could have been compromised! If you decide to walk into our office, make sure you weren’t followed! If you purchased a new prepaid mobile phone with cash… feel free to call us but do it from a secure location! Not your car, it could have been compromised. Call us from a location with background noise (white noise), e.g. a busy mall, and walk as you are talking, don’t stay stationary; don’t be paranoid… but safe and smart! Whoever you decide to use to conduct your TSCM, make sure the company retained is comprised of – knowledge, experience, and state of the art government grade equipment. TSCM Services is a science, you need a qualified technician searching the low Hz to high GHz ranges. There are numerous ways to eavesdrop and gather intelligence, below I list the most common attacks along with various equipment necessary to conduct a professional TSCM Sweep.
- Microphone and tape recorder: The most common and easiest type of eavesdropping. Very versatile… it can be worn, placed in a room, and even turned on remotely or by voice activation.
- Transmitters (Bugs): The microphone or video Intercepts the communication and transmits it as radio signals, i.e. 900 MHz, 2.4 GHz…etc. Some bugs are self-contained with microphone, transmitter and power supply. The sophistication ranges from simple intercom systems to professional government bugs. Since these devices are sending signals, we look to locate their spectrum waves; we do this by using a spectrum analyzer. Some bugs/transmitters are turned off and are turned on remotely, aka (remote bugs). This type of transmitter can defeat a spectrum analyzing sweep, as well as a thermal imaging sweep. If the remote bug is turned off, there wouldn’t be a signal sent to pick-up and detect, nor would there be much heat generated. Due to such, we suggest using a TSCM device that can locate transmitters turned off or hidden within walls. This type of TSCM device (Non-Linear Junction Detector) doesn’t search for signals or heat…but rather it locates, circuit boards, diodes, and the mini magnets needed within these devices.
- Through Wall Listening Devices: There is also equipment that can hear through walls, including brick walls; commonly used in situations with adjoining rooms (office, hotels, and apartments).
- Laser Bounce Listening / IR Devices: This is or was a high-tech method for eavesdropping, however with the change of technology and information on the Internet into how to build your own laser microphone, it has become more accessible. The laser consists of a beam, usually an invisible infrared beam (RF), like your remote control when you increase the volume on your TV; the laser is normally bounced off a window and it captures the audio. It then sends the audio information back to the person who is conducting the eavesdropping. Professional laser listening devices can shoot a beam into a hotel room from another building nearby to intercept what’s being said.
TECHNICAL SURVEILLANCE COUNTERMEASURES 101
Conduct a three-part search looking for Hardwire (HW), Radio Frequency (RF), and Laser/Infrared bugs. The three-part search will consist of a physical search, telephone/phone lines, and spectrum/audio search. Use GSA and DOD certified equipment!
Hardwire: (Telephone, Telephone Line, and Carrier Current Search)
Listening devices that can be attached to your phone, telephone line, telephone system or even transmit your conversations over the AC power, via Carrier Current transmissions. These bugs are often powered by the line itself, so it pulls low amperage (ohms), making it difficult to detect. They can also be placed on your line outside, at the junction box, and professionals can even tap into your lines miles away. Rest assured, we check your lines from your address to the telephone company central station. Our Time Domain Reflectometry equipment & spectrum analyzer sends signals through the line to the central office. We’re able to determine if your phones are being tapped from within your office or outside. Landline telephones produce amperage, aka (ohm) and our equipment will locate the amperage or ohm drain taking place and then locate the location of that drain. The AC wiring within your home or business can also transmit your conversations via Carrier Current. Right over the AC power wiring, rather than using radio signals. The eavesdropper can listen from any point along the AC wiring until it goes through the electrical company’s next transformer. Rest assured, we also search A/C outlets and Carrier Current transmissions.
Mobile Cellular Phone: (Computer Forensics)
Searching a Mobile Phone for a listening device is more computer nerd then James Bond, the process is different. The mobile device is a computer, where computer forensics will determine if information is being sent out of your phone without your knowledge. We are basically looking for a virus that is transmitting your data to another email or IP address you aren’t aware of. Cellular Phone Debugging needs to be conducted by a trained computer forensic expert (we have on staff).
Radio Frequency (RF): (Spectrum & Audio Search)
Sends wireless signals throughout the air, any FM/AM radio or scanner device can intercept these signals. RF transmitters can be as small as a regular bug, but they need power to operate, often making them larger. RF Bugs can be battery or hardwired for power. They can be located within electrical outlets, A/C vents, ceiling tiles, under furniture, etc. A Physical Search helps, but you need a professional RF locater, also known as a spectrum analyzer. Cellular phones, portable phones, and various equipment send signals, we are looking for these signals. A top-quality spectrum analyzer searches the low Hz, MHz, to high GHz frequency range.
GSM, TV, Wi-Fi, Bluetooth+ (Spectrum & Computer Signal Interception)
There are various new ways a culprit can gain access to your private information. They can strategically virus your Mobile Phone or TV to access the preinstalled camera and/or mic. Additionally, other forms of communication like Wi-Fi and/or Bluetooth are being used to hack your various devices, only to be turned against you.
IR Laser Listening Devices:
Often expensive, professional models are $25k+… but YouTube will teach you how to make a crude version. A laser (IR) “infrared” beam is shot into the room where observation is wanting to take place. The audio is transmitted back and decoded. The culprit shoots the IR invisible beam through a window or similar opening. Difficult to use for you need a direct line of sight.
NOTE: An operative could use an IR Listening Device and a RF transmitter… shooting the laser into a window while transmitting the data to a distant location, for the ultimate Intel and protection.

SELECTING A QUALIFIED TSCM PROVIDER:
- First, Verify the provider has attended a recognized TSCM academy. The ITC is the government school which is about 40 weeks long. The best private academy is REI located in Tennessee. Their courses are provided in modules, with the understanding the students have a communication electronics background. (Ask for copy of diplomas). The majority of vendors conducting TSCM have No formal training in the field.
- Second, Verify the provider has “real” TSCM equipment. State of the art detection equipment costs range from $100k to $300k plus! It’s NOT an inexpensive hobby. They should have: (1) OSCOR Blue Spectrum Analyzer, (2) TALAN Telephone Analyzer, (3) ORION Non-Linear Junction Detector, (4) FLIR Thermal Camera.
- Third, determine that the person providing the service conducts sweeps on a regular basis. Some firms conduct a few sweeps per year… you don’t need fancy equipment without a serious processional knowing how to use them.

Government Grade TSCM Debugging Equipment:
RADIO FREQUENCY SPECTRUM ANALYZING is performed using the REI OSCOR Blue.
The RF spectrum from 10 KHz to 24 GHz (as a minimum) is examined. Radio transmissions are captured and mapped to identify the presence of covert transmitters from within the protected area. (This analyzer will detect the latest burst, spread spectrum and frequency hopping devices, which is why federal
intelligence agencies use the OSCOR Blue.)
DIFFERENTIAL RF ANALYSIS is performed using the Audiotel Delta V analyzer. Radio signals from 50 KHz to 5 GHz are processed using differential comparison techniques. (In metropolitan areas with high RF saturation, this detector pinpoints the transmitter source.)
CELLULAR TESTING is performed using the Blood Hound. Covert GSM transmitters are pinged using a proprietary technique to analyze up link utilization. (The new era of surveillance technology is cell phone frequency bugs, which the majority of detectors will ignore.)
REAL TIME SPECTRUM ANALYSIS is performed using the RF Hawk. This analyzer covers 50 KHz to 6 GHz. (The DSP allows us to look inside conventional radio signals to detect covert transmitters broadcasting within legitimate carrier envelopes. It was specifically designed to identify, track and locate radio transmissions. Less than 2% of sweep firms have this technology.)
INFRARED THERMOGRAPHY is performed using the FLIR Scout to identify thermal signatures from covert devices. (Thermal signatures given off by covert surveillance devices and can be seen, when converted to visible light.)
NON-LINEAR JUNCTION DETECTION is performed using the REI ORION. High frequency RF signals are beamed into critical surface areas to illuminate covert electronic devices. (Virtually all surveillance technology uses electronic components, which are detected even if the device is switched off.)
ADVANCED TELEPHONE ANALYSIS is conducted using the REI TALAN. Comprehensive electrical measurements are taken on all line permutations for voltage, current, resistance, capacitance, audio paths, and line based RF signals. In addition, Frequency Domain Reflectometry is utilized to identify suspect connections on copper conductors. As a final test, NLJD is performed on all line pairs to detect unauthorized electronic devices.)
WI-FI ANALYSIS is performed using the Air Magnet LAN Analysis and Spectrum Analysis Software / Technology. Specific devices are mapped and analysis is performed on each signal encountered. (Many surveillance devices operate of Wi-Fi / Bluetooth Technology).
FIBEROPTIC INSPECTION is conducted using a variety of manual and electronic imaging techniques to examine areas which offered limited accessibility. (Digital Voice Recorders and Covert Cameras are often hidden in HVAC ducts.)
