Audio recorder and phone jammer F18
The F18 eavesdropping jammer by Spreest is a portable device designed to protect confidential conversations from unauthorized recording by phones, voice recorders, and other audio recording devices.
The F18 model stands out with its discreet casing resembling an elegant tissue box, allowing it to blend naturally with the decor of an office, conference room, or private office.
The device uses special acoustic signals that mask speech and make it difficult to obtain a clear recording. It provides 360° protection, securing conversations in all directions around the device.
NOTE! The device does not work with all voice recorders/phones. For example, it effectively jams Android mobile phones and some iPhone models.
Key Features
1. Electromagnetic interference-free technology – Operates by masking speech signals with acoustic waves, without blocking cell phone signals, Wi-Fi, or other radio transmissions.
2. 360° Protection – Four independent emission directions provide protection up to 8m around the device.
3. Discreet tissue box form – The device is hidden in a robust, compact ABS and wood casing, allowing it to blend naturally into the decor of an office or conference room.
4. Two operating modes – Strong mode provides maximum effectiveness, while weak mode allows for reduced signal emission.
5. Voice control – Once activated, the device automatically starts operating upon detecting a conversation and switches to standby mode when no speech sounds are detected in the environment, which helps save energy.
6. Remote control operation – The remote allows for convenient control of functions and operating modes without approaching the device.
7. Standby mode – Facilitates quick pausing of the device's operation without completely turning it off.
8. Simple and intuitive operation – Simply position the device, direct the active sides towards the protected area, and flick the selected switches to begin operation.
9. Battery charge indicator – Built-in lights allow for a quick check of the battery level upon starting the device.
10. Efficient device operation – The 5200 mAh battery provides approximately 3.5 hours of operation on a single charge. The jammer can also operate when connected to a charger.
