Infratornado is a new product of Selcom, which designs and produces highly specialized equipment for professional applications. The audio jammer operates in the amateur frequencies band 433.92 MHz, so the noise generator jams microphones which are applied in pioneer mobile phones such as iPhone, HTC, Samsung, Sony and etc. All kinds of video cameras with microphones and voice recorders both amateur and professional ones will also become useless in the vicinity of this noise generator.

The Infratornado® 2020 device uses a unique system to generate jamming signals that are dynamically variable in the time. The comparative tests carried out show that this system provides about 30 percent more effective jamming of listening devices than other available jammers this type. In addition, proper placement of ultrasonic transducers has allowed to reduce harmful negative interference (quenching) of emitted jamming waves. It is recommended that after 45 minutes of staying within the range of the device, take a break of about 15 minutes (Not obligatory). Attention: Within the reach of the Infratornado® 2020 device should absolutely not stay pregnant women, people under 18 and animals (dogs, cats).

The Infratornado® 2020 device has no built-in programmable processors with volatile and non-volatile memory, ROM, PROM, EPROM or EEPROM and no radio transmitters, receivers, Wi-Fi, bluetooth, GSM and no other ...

Jamming microphones of such popular devices like:

    • smartphones - iPhone, Samsung, LG, Sony, HTC smartphones and many others,
    • iPads and tablets,
    • microphones in professional voice recorders Edic or those in credit cards etc,
    • microphones in wireless video cameras.

  • Important!
  • When using supersonic microphone jamming technology it is necessary to remember about limitations resulting from the laws of physics. Effectiveness of jamming depends on the device - the design of some microphones is more susceptive to jamming than of others. For that reason, the maximum effective range of the device can fluctuate around several times. Ultrasounds also bounce off the surface, but they can not penetrate most materials to a great depth, so it is advisable to use the right number of equipment and its location in the room to provide the best security to the privacy of the conversations.
  • The device does not guarantee 100% of the jamming performance, but it outperforms competing solution with its configuration for high performance against microphone in devices such as voice recorders, eavesdropping and seismic microphones, microphones in computers, headsets, cameras and cell phones.
