F11 High power recording Jammer

The "F11" device is engineered to secure conversations by obstructing the recording of sensitive voice data. It effectively prevents unauthorized use of voice recorders, mobile phones, and disrupts software designed for recognition and interference filtering.

Key Features of the F11 Voice Recorder Jammer

The F11 voice recorder blocker uses ultrasonic signals to disrupt the functionality of recording devices. By emitting high-frequency interference, it prevents microphones from capturing intelligible audio, effectively safeguarding voice information. The ultrasonic signals are safe for human health and almost imperceptible to the human ear, ensuring discreet operation.

The device is operated via switches located on the back panel. Each switch controls a specific group of ultrasonic emitters, allowing users to customize the interference direction based on the position of recording devices. This feature makes it adaptable to various environments and scenarios.

For optimal performance, place the jammer at table level with its front side facing the target device. The recommended distance for disrupting a voice recorder is up to 3 meters, while for wired or wireless microphones, the range extends to 5 meters in direct line of sight.

It's important to note that hearing aids should not be in use when operating this device, as the ultrasonic signals could interfere with their function.

This innovative jammer combines ease of use, effectiveness, and safety, making it an ideal tool for protecting sensitive conversations in meetings, interviews, or private settings.
