National Surveillance and Intelligence specialise in the field of Technical Surveillance Counter Measures (TSCM) using the most advanced knowledge and up to date equipment available on the market to protect our clients.

TSCM; also known as electronic bug detection, bug sweeping or surveillance counter measures; is the method of electronically and physically inspecting offices, buildings, homes, vehicles, telephone systems, network systems and cabling for the existence of eavesdropping devices and to identify weaknesses in security that could potentially be used to install illegal devices.

The equipment our TSCM Bug Sweep team uses is used by Intelligence agencies, Defence departments and governments worldwide, especially Australia (DFAT, DoD, ASD). With this equipment we are able to detect the presence of active and passive bugging devices, digital burst/packet bugs, hidden camera setups, keystroke logging devices, telephone interception and wiretaps, laser and infrared beams and more. We always keep up with new technologies to ensure you get the best possible service.

Depending on the threat level, we will determine where to cap our frequency range, which currently scans up to 43 GHz in real time, more than any other device or equipment on the market. As a comparison, devices used by other companies in Australia will generally scan up to 12 GHz and only some companies will have a 24 GHz capability.

After tailoring a package suitable to your needs, your TSCM Survey/Bug Sweep includes a full technical threat assessment that comprises of:

  • Radio frequency spectrum analysis;
  • Non-Linear Junction Evaluation;
  • Thermal Emissions Analysis;
  • Telephone and network analysis;
  • VoIP system analysis;
  • Electronic inspection for covert video setups;
  • Carrier current analysis of AC outlets and cabling throughout the premises;
  • Physical search for hidden transmitters, microphones, and cameras.

Nowadays, it’s so easy to obtain from the Internet and install electronic bugs, listening devices, hidden cameras, Bluetooth bugs, infra-red beams, burst/packet bugs, spread spectrum and other similar eavesdropping devices. Thus the threat is rising rapidly as covert equipment and techniques become more complex and sophisticated.

Fortunately, with NSI by your side, you can secure valuable intellectual property, financial data, and trade secrets. We protect you by detecting active and passive threats internally, externally, on and off site.

Homes can also be the target of listening devices that can be used by criminals for extortion and theft. Other target areas include vehicle’s that can be tracked by GPS trackers and hotel rooms where private meetings may be held.

If you suspect someone is spying on you at your workplace or premises – call us immediately! However, do it from a safe location, i.e. phone box or mobile phone away from the potential threat. Avoid significant discussions in the surrounding area until we are able to confirm the room or phone line is safe. Our experienced operatives will arrange a private meeting and determine the best course of action to take in order to save your intellectual property, financial data, and trade secrets from being stolen.
