SEL ULTRA SPEAKER - Ceiling Jammer of Microphones and Audio Recorders

Device is an effective jamming device, producing a complex jamming signal in the ultrasonic band above the point of human hearing. A system of high-quality ultrasonic transducers controlled by a microprocessor that achieves the best possible jamming efficiency and makes any recorded conversation impossible to playback. Due to jammers ceiling mounting position, a multipath propagation effect is created, which reflects the generated noise from surfaces and items, further increasing the suppression area and efficiency.

 

• Type of work: proprietary software for generating digital ultrasonic jamming signal;

• Easy to use control: can be turned on/off via presence of power in the power supply line.

• The radio remote control turns jamming noise off and on;

• Quiet operation – does not emit an audible and troublesome sound;

• Simple operation and use.

• Easy mounting spring brackets.

 

Device effectively blocks wiretaps, voice recording and microphones in a distance of ~3metres such as:

• microphones in cell phones;

• digital recorders of the sound with the built-in microphone or the microphone on the cable;

• professional digital dictaphones of the type : EDIC-the mini, Gnome, Olympus, Papyrus...;

• dictaphones built-in in Smartphones of the type the Iphone, HTC, SONY , LG, SAMSUNG...;

• radio microphones, microphones of recorders audio-the video;

• microphones of cameras, bugging microphones;

• professional dictaphones hidden in cards to ATMs;
