Professional Audio Surveillance,
 Counter Surveillance & Spy Equipment
 Manufacturer

JJN Electronics was formed in 1996 primarily as a manufacturer of spy equipment and covert listening devices otherwise known as bugging devices or listening devices. Covert surveillance has become a much needed industry and has led us to develop many different types of audio surveillance bugging devices and listening devices such as room transmitters either as miniature modules as slim as 5mm or covert listening devices hidden in every day items such as pens, calculators, computer mice, British and European mains adaptors and sockets.

In the early stages of the company JJN Electronics developed UHF spy equipment and telephone surveillance equipment using UHF crystal controlled technology. Our covert listening devices became widely regarded as the most superior in terms of sound quality, transmission capability and reliability. These products became standard surveillance equipment for high-level clients such as government agencies, high end business users and security forces. The success of these spy devices enabled us to push on and develop products, which are even more advanced and sophisticated by using cutting edge GSM technology.

Our latest just released product range of GSM audio surveillance devices include the miniature GSM3000D. This tiny spy device measures just 63 x 41 x 21mm. Ultra miniature components and painstaking design have produced one of the smartest types of surveillance equipment on the market. This GSM spy device can be placed in a home, office or car and can be called from any phone anywhere in the world and allows the user to hear exactly what is going on in their absence. By using the GSM network, reliable audio surveillance can be achieved without any range limitations. You can monitor your office for example when away on holiday in another country, making this piece of spy equipment a must for personal and business security.

The same GSM technology is also integrated into our range of covert listening devices such as Mains Adaptors, Table Lamps, Clock Radios, Smoke Alarms and we can also build bespoke spy devices for individual requirements using this latest spy technology. Past clients have requested GSM surveillance equipment built into televisions, computers, briefcases etc.

Due to the success of our covert listening devices we found a huge demand developed for counter surveillance equipment otherwise known as bug detectors, telephone tap detectors and general anti spy equipment detectors. Our knowledge of room and telephone surveillance equipment gave us an insight as to what was required to design and build high-end counter surveillance equipment. JJN Electronics have produced our own range of the most sophisticated bug detectors on the market today starting with our entry level bug detector the PRO4000D which detects all common types of covert listening devices, the ultra sensitive PRO5000D which detects all listening devices and transmitter telephone taps and finally the top of the range PRO6000GSM which detects the latest digital covert listening devices, telephone taps and new GSM bugs which are the latest additions to the covert surveillance and bugging device market. Despite their technical complexity all our counter surveillance bug detectors are designed to be simple to use with no formal counter surveillance training required.

NEW SPY EQUIPMENT:

The New Sweepmaster F2560 Counter Surveillance System is portable kit offering the most sophisticated detection of spy equipment transmitters.

As well as detecting all standard audio bugging equipment and the latest digital spy equipment it features a telephone tap detector enabling users to monitor their telephone lines for transmitting bugging devices and hard-wired telephone listening devices.

The Sweepmaster F2560 also features a Frequency Counter to enable faster location and disablement of covert bugging and listening devices.
