JJN Digital Detection

JJN Digital products are designed and built in the UK to the highest specification and are used by countermeasures professionals worldwide. Their clients include government, police, prisons, businesses, and professional sweep teams.

JJN Electronics was formed in 1996 as a manufacturer of specialist electronic surveillance equipment. In its early years the company developed a reputation for producing high specification audio surveillance devices that became widley regarded as the most sophisticated products on the market in terms of sound quality, transmission capability and reliability. These devices became industry standard surveillance equipment for high-level clients such as government agencies and security forces. The quest for longer transmission ranges lead JJN to become pioneers in developing ultra-miniature GSM audio devices with no transmission range limitations.

In 1998, following a customer request, our knowledge and expertise of radio transmission technologies lead us to develop our first Wideband Radio Frequency Detector or 'Bug Detector' the PRO5000D. The product was received with great acclaim for its small size, high end performance and simplicity of use. Since then we have tirelessly continued to develop a range of counter surveillance products that give users the power to detect the latest types of devices as they come to market. Over the past two decades, with rapidly developing technologies, the challenges facing JJN included detecting conventional VHF/UHF listening devices, wireless video devices, GSM, GPRS and then 3G devices, GPS tracking devices, frequency hopping, spread spectrum devices and SHF (Super High Frequency) devices. More recently the latest detection challenge has been the new ultra fast 4G cellular network and the latest ‘Store and Forward’ Wi-Fi/Bluetooth based devices.

Their mobile phone detection products are now being used in environments where mobile phone usage is prohibited, such as boardrooms, prisons, hospitals, exam halls etc. Our high sensitivity detectors allow users to be instantly notified of unauthorised mobile phone activity and to locate the position of the target phone.
