How does Bug Sweep work and bug sweep cost

How does Bug Sweep work?

 It is done in several phases. In the first phase, a radio frequency scan is conducted with a real time spectrum analyzer run through Kestrel TSCM Professional Software. All radio frequencies in the facility are recorded and evaluated for any rogue frequency emanating from within the facility under TSCM survey. If such a rogue frequency is available in the radio frequency spectrum, it is isolated, located and neutralized.

There are amateur operators posing as professionals, carrying handheld amateur bug detectors. Such detectors cannot differentiate between strong radio frequencies coming from outside the facility and a bug planted in the facility.

Next phase is to scan the facility with a highly sensitive thermal imager. Normal thermal imagers are handicapped in detecting heat footprints of bugs which are in the sleep mode, yet consuming power to become active at a predetermined day and time.

Telephone analyzer checks the landline telephone instrument and the telephone line for any kind of telephone taps.

Then there are several tools a TSCM Specialist has to detect different hidden electronic bugs. Cavities that cannot be accessed with the naked eye require the services of an endoscope or a borescope etc.

How much does bug sweep cost? 

Depends from twenty thousand onwards for a small room. It all depends on the location, size of the facility, electronic equipment it has, work stations etc.

Hard wired 

Certain electronic bugs can be hard wired to the existing power supply clandestinely so that it does not require recharging or replacing the batteries time and again.

Catch the Spies in your Boardroom

The boardroom is a very important place where significant, confidential and crucial decisions take place. A competitor can get such information easily. Information leakage will lead to a serious security threat. Thus, a TSCM Sweep before such crucial meetings sanitizes the boardroom and cleans it of electronic bugs. These swept rooms are known as Bunker or War Room.

AV 2 Group is in TSCM (Technical Surveillance Countermeasures) Bug Sweep Services for the past 20 years. We have highly skilled teams to help you secure your boardrooms and hence the important information with it.

Thermography Survey

Statistics reveal that electrical equipment damage and lost connections cause 25% -30% of all failures to switchboards, switches, circuit breakers and cables. This type of fault is easy to detect using Infrared cameras. AV2 Group team will trace, quantify and trend the fault, allowing the management of the site to plan repairs during scheduled stoppages instead of panic reaction during sudden failures, let alone the possible risk of fire which can be catastrophic for the personnel and business. Our thermography survey helps reduce down time which will cost business in lost production time.

We recommend regular thermography surveys of the following types of equipment:

  • Fuse boards
  • Distribution boards
  • Busbar systems
  • Control panels
  • High voltage and medium voltage systems
  • Power line connections and insulators
  • Switch-gear
  • Electronic components
  • UPS and battery systems
  • PLC connections
  • Motor control centers
  • Transformer
  • DG Set

      Electrical Thermography

      At AV2 Group we conduct infrared thermal imaging of machinery and electrical panels, helping the end user to detect faults before they become major issues. Our thermal imaging equipment produces accurate real time high resolution images; enabling engineers to detect problems that might otherwise go unnoticed. This also gives them the opportunity to undertake remedial maintenance prior to costly system failures or production stoppages. Using infrared thermography is effective across all sectors in helping to reduce maintenance costs and even identify possible improvements.

      Thermography is an excellent diagnostic maintenance tool that improves both efficiency and reliability of plant systems. Such surveys are conducted while the equipment is working under normal operational conditions, any problems will be quickly located allowing time to schedule maintenance immediately or when convenient for the production.

        Telephone Analyzer ETA-3A

        The ETA-3a has been specifically designed for testing both single line and electronic business telephones in use worldwide today. You can measure operating voltages, measure instrument current do multi-tone sweeping and test all combinations of wires in up to an 8 wire cable (or
        more with adaptors)

        Tests New Phones and Systems
        Besides testing single line phones and fax machines, the ETA-3a is compatible with all types of electronic telephones systems and is the best way to safely test digital, hybrid and VOIP instruments.

        Audio Amplifier
        The ETA-3a uses an isolated high gain audio amplifier to check for even minute amounts of room or telephone audio on the wires being tested. This enables the user to tell if digital telephones have been modified and are sending room audio as data. The amplifier can be used on-line or off-line. In
        off line mode, it supplies the DC bias voltage required to energize electrets microphones or other types of listening devices.

        Multi-Tone Sweep
        The ETA-3a uses a unique multiple tone generator to detect infinity transmitters. Selectable Uni-tone or Multi-tone thoroughly tests phone lines for these attacks.
        High Voltage Testing
        High Voltage tests are designed to detect eavesdropping attacks utilizing bypasses on telephones that have mechanical hook switches . Voltage is adjusted by panel controls and displayed on the LCD meter. High Voltage cannot be accidentally connected to sensitive electronic systems and instruments.

        Simple Operation
        All required accessories and cables are included. So is a detailed test and
        operations manual. The ETA-3a is powered by internal gel cell batteries. Its
        charger operates on 110/220 VAC, 50/60 Hz.
