SEL-324V Slim – compact noise generator – microphone blocking

The SEL-324V Slim noise generator is a compact variant of the SEL-324A. The smaller size allows installation in hard-to-reach places, such as under a table, in a study or in a car. Ultrasonic waves of 24-26 kHz will block microphones in spy devices within a radius of up to 4 m protecting private conversations from eavesdropping.

The Russian company Selcom security for years has specialized in effective protection against surveillance. The SEL-324V Slim compact noise generator of this renowned brand will disrupt hidden spy devices with high efficiency: voice recorders, radio and GSM eavesdroppers and smartphones. Unlike the SEL-324A model, which is designed to protect larger spaces (such as conference rooms), the SEL-324V Slim was developed for use in small spaces such as private offices and car interiors. With a special magnetic mount, the unit can be easily mounted under a flat surface of your choice, such as a table or desk. The ultrasonic waves which are inaudible to the human ear, act directly on the microphone diaphragm, making it impossible to record or listen to a clear sound. A range of up to 4 meters and remote control with the included remote control combine to effectively disrupt eavesdroppers, voice recorders and other spy equipment. A great choice for stand-alone use or as a complement to the SEL-324A.

Key features of the SEL-324V Slim compact noise generator

• 

  180° noise emission

  24 ultrasonic transducers around the perimeter of the semi-circle generate noise over a wide 180° range from 24 kHz to 26 kHz. The operation of the generator makes recorded or overheard conversations completely incomprehensible.

• 

  Compact size

  The main advantage of this model is its compact size and ergonomic semi-circular shape. This, combined with the supplied magnetic mounts, allows for quick and easy installation, e.g. under a desk or car dashboard.

• 

  Comfortable operation

  The ultrasonic waves produced are inaudible to the human ear affecting only the operation of spy devices. The interference of the microphone takes place with maximum comfort for those talking.

• 

  Range up to 4 m

  The compact noise generator blocks eavesdropping devices within a radius of up to 4 meters. The actual range may vary depending on room acoustics, microphone type and location, among other factors.

• 

  Combination of two devices

  It is possible to combine two SEL-324V Slim generators into one circle with 48 transducers for double the effectiveness.

• 

  Unlimited operating time

  The directional ultrasound generator uses mains power, so it can operate for an uninterrupted period of time.

• 

  Remote control

  It comes with a wireless RF remote control that allows you to operate the device remotely.
