Locate bugs and cellphone listening devices

August 2004 Information Security, Products & Solutions

Marshall International, exclusive distributor of the Audiotel range of electronic countermeasures equipment, is now offering Sig-Net, its new affordable handheld bug detector.

Sig-Net has been designed to address the massive increase in the use and abuse of cellphones as covert listening devices.

Using the latest advances in large scale integrated electronics and RF processing, Audiotel has produced a versatile, low-cost detector, bringing effective bug sweeping within reach of all businesses, departments and individuals.

"In addition to the obvious counter-espionage applications, considerable interest has been shown from public services such as hospitals, prisons and schools as well as the aviation industry where the use of mobile phones is undesirable or hazardous," says Marshall International CEO, Harold Marshall.

Optimised for detecting local concealed transmitters, Sig-Net detects all types of analog and digital transmitters including elusive burst transmitters such as the latest GSM phones. With user definable alarm functions Sig-Net can be used to protect sensitive meetings in realtime.
