P-US-K7 Cheap Handheld Dual Jam Audio Anti Monitoring Equipment

Your conversations need protection! With this handheld anti listening jamming device, all the efforts of eavesdroppers will be in vain.

P-US-K7 is an efficient recording jamming device designed to block the operation of various recording and listening devices. Combining two voice jamming technologies, it can effectively protect the security of voice information.

There is an ultrasonic transmitter on the right side of the device, and the jamming range can effectively cover an area within 4 meters. There is a power button and a rotary knob for turning on and adjusting the voice volume on the front panel, with moderate rebound force and rotation damping, providing a good operating feel.

With a built-in speaker and a connector for connecting an external speaker, the jamming capability can be expanded to effectively prevent laser equipment from eavesdropping.

This recording interference device uses dual interference modes for comprehensive protection:

Ultrasonic interference: The device can generate ultrasonic signals that are inaudible to the human ear, directly acting on the internal amplifier of the recording device, interfering with its sound wave pickup function within a medium and short distance. This interference will have an irreversible impact on the recording device, making the recorded content impossible to restore or understand, even for high-end devices.

Voice-like interference: It can generate pseudo-random noise interference similar to human speech, completely disrupting the information captured by the recording device. This interference completely distorts the original voice signal, making it impossible to restore or analyze.

These two interference methods can be used separately or in combination. For example, if a silent environment is required, only enabling ultrasonic interference can meet the needs.

This cheap portable anti monitoring equipment can interfere with a variety of modern recording devices, including but not limited to:

• Recorders
• Wireless and wired microphones (covering all frequency bands)
• Smartphones and ordinary mobile phones
• Laser pickup devices (can be connected to external speakers to expand the interference range)
• Other monitoring devices with microphones (such as stethoscope-style monitoring devices, etc.)

In tests, P-US-K7 achieved a nearly 100% interference effect on modern smart devices. Even for some older models (such as outdated mobile phones), the interference efficiency can still reach 85%-90%.

How to operate the jam audio signal equipment?

Prepare the equipment: Charge the battery as needed, or plug the device into a power source using the included power adapter.
Start the device: Press the power button on the front of the device to start it, and aim the ultrasonic transmitter on the right side at an area where a microphone may be hidden, such as a visitor or suspicious object.
Activate jamming mode: If you choose to use the voice-like jamming mode, you do not need to aim at a specific target area, as this mode can completely block all listening devices.

How to get the best results?

1.Conversation distance: Keep the distance between the two parties in the conversation within 1-1.5 meters and talk at a normal volume.
2.For multi-person scenarios: If only silent ultrasonic jamming is used, it is recommended to invite participants to place their mobile phones near the ultrasonic transmitter of the device. This will not affect the normal function of the mobile phone (such as answering calls), but it can completely block its recording ability.
