Description
Business room protection against eavesdropping - Defender Tower AT
Defender Tower AT is a professional equipment that prevents reception as well as recording of sound. Thanks to its 4-column design, it is able to effectively protect a room of 16 to 20 m2.
Defender Tower AT serves as a jammer of the means of receiving as well as recording audio by devices such as cell phones, voice recorders and eavesdropping devices. This prevents them from being used as surveillance tools.
The Defender's scheme of operation boils down to generating two independent tracks, white acoustic noise. Emission in the first channel takes place in the frequency band audible to the human ear (16 Hz - 20 kHz). The second channel is a band of inaudible frequencies - close to ultrasound (25.5 - 26.5 kHz).
The signal of the generated noise puts the microphones into resonance, which effectively prevents the reception and recording of human speech. The device is effective in disrupting membrane microphones as well as laser and contact versions.
The Defender Tower AT set consists of four units. The entire unit is controlled from the remote control included in the kit. For effective protection against recording, it is necessary to place the units in a rectangular / square shape at a distance of no more than 4-5 meters from each other.
- Important!
- When using ultrasonic microphone jamming technology, always keep in mind the limitations of the laws of physics. The effectiveness of jamming depends on the device in question - the design of some microphones is more susceptible to jamming than others. Depending on this, the maximum effective range of the device can vary up to several times. In addition, ultrasound bounces off surfaces, but is unable to penetrate most materials to great depths, so it is recommended to use devices in sufficient number and spacing in a given room to best protect the privacy of conversations conducted in it.
