When using supersonic microphone jamming technology it is necessary to remember about limitations resulting from the laws of physics.microphones in professional voice recorders Edic or those in credit cards etc,.smartphones - iPhone, Samsung, LG, Sony, HTC smartphones and many others,.Jamming microphones of such popular devices like: 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. Attention: Within the reach of the Infratornado® 2020 device should absolutely not stay pregnant women, people under 18 and animals (dogs, cats). It is recommended that after 45 minutes of staying within the range of the device, take a break of about 15 minutes (Not obligatory). In addition, proper placement of ultrasonic transducers has allowed to reduce harmful negative interference (quenching) of emitted jamming waves. 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. The Infratornado® 2020 device uses a unique system to generate jamming signals that are dynamically variable in the time. 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 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. Infratornado is a new product of Selcom, which designs and produces highly specialized equipment for professional applications.
