Thin semicircle ultrasonic jammer SEL-324V
SEL-324V is a thin, small size microphone (including cell phone microphones) and audio recorder jammer with semicircle-shaped jamming pattern for deployment in environments with complex geometry: under desks and tables, inside automobiles, and other.
DESCRIPTION
Specifications
* Effective jamming range may vary based on type of microphone of the audio device and its relative position to the jammer.
Ultrasonic transducers in the SEL-324V are installed in a thin (the height of the device is only 25 mm), single-line sector-shaped array, providing reliable jamming within a 180° sector-shaped area around the device, which makes it a perfect choice for manual installation in meeting rooms and automobiles.
Features:
- An array of 24 high-quality piezo-ceramic transducers, installed in a semicircle shape, controlled by a microchip that automatically shifts the noise signal in time and frequency domains, achieving best possible jamming efficiency and rendering any actual speech signal on the microphone unintelligible.
- Flexible power supply: device can draw power either from the 220V mains, from a car 12V onboard power supply socket, or from a built-in Li-Pol battery, with capacity enough for 3 hours of continuous operation.
- Easy to use control: can be turned on/off via a button switch on the device, or wirelessly with a special RF remote control.
- Indicator dashboard: device constantly gathers self-diagnostic and battery charge data and outputs it to an easy-to read LED indicator dashboard on the bottom panel of the device.
- Optional magnetic mounting system (please, send an explicit request for this option during your order).
