SEL-324A ceiling microphone jammer -blockade of microphones in wiretaps

The SEL-324A ceiling microphone jammer is an effective way to protect your office space from eavesdropping. The device produces ultrasonic waves that block microphones in voice recorders, eavesdroppers and cell phones, among others. Easy ceiling mounting, unlimited operating time and optional remote control are the key features of this model.

Effective protection against data theft is one of the priorities in enterprises and institutions. The most common method used in economic espionage is hiding DVRs and wiretaps in offices, conference rooms and offices. To prevent this, it is enough to invest in the SEL-324A directional acoustic noise generator developed by the renowned company Selcom security. Mounted on the ceiling, the device produces ultrasonic sounds at frequencies of 24-26 kHz within a radius of up to 4 m. The noise, inaudible to the human ear, influences directly the microphone diaphragm, disrupting its operation. As a result, the SEL-324A ceiling microphone jammer blocks most types of eavesdropping devices with built-in or external microphones, such as voice recorders, smartphones, cell phones and GSM and radio eavesdroppers. By using the multipath propagation phenomenon, the effectiveness is further enhanced.

Key Features of the SEL-324A Noise Generator

• 

  Effecive interference with call recording

  A set of 24 microprocessor-controlled piezoceramic transducers is responsible for the best possible jamming performance. As a result, speech recorded by spy devices becomes completely unintelligible.

• 

  Discreet operation

  The device produces ultrasounds below the threshold of audibility for the human ear, so the blocking of microphones in the eavesdropper does not cause any discomfort to the participants of the conversation.

• 

  Easy installation, discreet appearance

  The ultrasonic generator is designed for easy installation on the ceiling of any room.The inconspicuous appearance of the ceiling speaker will not draw any attention.

• 

  Multipath propagation

  When ceiling-mounted, the SEL-324A produces a multipath propagation effect that deflects generated noise away from nearby surfaces and objects, further increasing the attenuation area and effectiveness.

• 

  Range up to 4 m

  The SEL-324A noise generator suppresses microphones within a 4-meter radius. The effective range may vary depending on the type of microphone and its position relative to the unit.

• 

  Remote control

  The unit can be operated manually or conveniently by remote control (not supplied).
