Our History
First incorporated in 1978,  Audiotel was initially based upon the success of the Scanlock Harmonic Receiver. The Scanlock had originally been designed and built by Lee Tracey whilst working for a branch of the government and was sold through Technical Security Limited. The Scanlock proved so successful that Lee decided to leave the government and form Audiotel to further enhance, manufacture, sell and support the product. 

Eventually in 1987 Audiotel was sold to Andrew Martin who led the company until his untimely death in 1997. During the first two years of ownership, Audiotel moved to Corby Northamptonshire from London and acquired Security Research. With the acquisition it gained access to the latest developments of Charles Bovill’s NLJD (Non Linear Junction Detector) designs. New developments and products quickly followed and Audiotel enhanced it’s reputation as becoming one of the world’s leading experts in the field of Technical Surveillance Countermeasures (TSCM). With Andrew’s death in 1997 the company entered into a period where it was run by trustees of Andrew’s estate. 

New developments and investment in staff continued; including the company’s largest contract of the time, supplying a modified (patented software algorithm) SuperBroom unit (NLJD) to the Indian Army for use in detecting the triggers used in the construction of Improvised Explosive Devices (IEDs). 

This then lead to the company being sold in 2003 to a London based investment company. A larger follow order from India was received and supplied a year later for the same equipment. This signified that the technology in the NLJD could be adapted for the purpose of detecting the triggering mechanisms used in the manufacture of IED’s. 

In 2009 the company took on further high performance C-IED development work which would eventually result in the largest contract to date being placed with the company in 2011.This resulted in the eventual move to a purpose built larger premises still within the Corby area.

The company continues to innovate, design, develop, manufacture and supply products to the world wide government, corporate and defence markets.
