Who would have thought? Such an audio interference generator that looks like an ordinary speaker actually has powerful recording and communication signal jamming functions!
This speaker type cellular network jammer is equipped with 96 high-efficiency ultrasonic transducers, which can generate dense ultrasonic signals to effectively suppress various microphones. Its 360-degree omnidirectional signal propagation can cover the target area without adjusting the direction.
The compact design allows these transducers to be integrated into a sturdy casing, optimizing space utilization while ensuring the portability and durability of the device.
The cell phone and recording scrambler supports three independent working modes, which can be enabled individually or combined as needed:
Ultrasonic mode: Start the ultrasonic transmitter to generate high-frequency signals to interfere with the recording device, which is suitable for targeted audio shielding scenarios.
RF interference mode: Block wireless signals such as cellular networks, WiFi and Bluetooth, effectively cutting off data transmission channels.
Acoustic noise mode: Generate complex “choir” type strong background noise through the built-in 15-watt speaker to interfere with the audio recording effect.
The three modes can be operated separately or flexibly combined to meet the needs of various scenarios. When there are no obstacles between P-UTBA and the target device, the best interference effect can be achieved.
The shell is made of high-quality thermal conductive material, and the cylindrical structure optimizes the heat dissipation path, which can quickly dissipate the heat generated during the operation of the device. Two silent fans are built in, which are used for air supply and exhaust respectively, effectively reducing the heat accumulation during long-term work.
The electromagnetic interference range of the device has been precisely designed, and it will not affect the surrounding irrelevant equipment (such as surveillance cameras, traffic signal systems, etc.) during operation, ensuring the environmental protection and safety of use.
P-UTBA is equipped with a dedicated remote control, which can be remotely operated within a certain range, including remote activation, mode switching and function control functions.
The package comes with an impact-resistant plastic storage protective box for storing the host, charger and remote control. It is not only convenient to carry with you, but also prevents the device from being damaged due to collision during transportation.
