• GSM a UMTS spying devices
• radio spying devices
• mobile phones and PC
• digital and analog dictaphones
• spying devices based on microphone, placed in various things like button, tie, watch,
videorecorder and many other common recording devices.
• The device operates on the principle of saturation the spying device microphone with
ultrasound which is of proper frequency and it results into input amplifier circuits limitation.
• Frequency combination of ultrasound is generated with respect to elimination of local points
(nodes) with low level of ultrasound. This enhances the efficiency of the device greatly.
• USJ-02-Disc is designed to cover space by ultrasound in horizontal range of 360°
. Vertical
angle of ultrasound beam is approx. 40°
, so majority of acoustic power is radiated in horizontal
direction.
• Acoustic signal corruption caused by ultrasound and by limitation of electric signals in device
circuits makes original audio signal unrecoverable.
• The device is designed as a flat, easily portable device. Height is 40mm, diameter 120mm.
Suitable as a personal jammer, for example for placing on a table during a meeting.
