Overview

Do you know what happens the moment a mobile phone enters your confidential meeting room? One person discreetly snaps a photo of a classified document, sending it off before anyone blinks. Another might pass along key points to people outside, putting your plans and strategies at risk.
Every unblocked device is a ticking time bomb—threatening security, destroying trust, and letting external influence into spaces that must remain strictly confidential.

The K-14 is a versatile wall-mounted signal jammer designed to protect confidential meeting rooms.

FAQs

  1. Is the omnidirectional signal blocker effective in high-signal environments (e.g., near mobile towers)?
    Yes, even in areas with strong external signals, such as near mobile towers, our omnidirectional blocker ensures reliable performance due to its high-power RF modules and high-gain antennas, protecting your confidential meetings from external interferences.

  2. Will the signal blocker interfere with other electronic devices like projectors or microphones?
    No, the blocker only affects wireless communication signals (mobile, Wi-Fi, Bluetooth, GPS) and does not interfere with wired devices such as projectors or microphones, ensuring smooth operation of all equipment during sensitive meetings.

  3. Can I adjust the jamming range for my confidential meeting room?
    Yes, the jamming range is adjustable from 7m to 50m, allowing for precise coverage of your meeting space without disrupting adjacent areas, ensuring the confidentiality of discussions.

  4. Will multiple omnidirectional blockers interfere with each other in a conference room setting?
    No, with proper placement, multiple blockers will not interfere with each other. We provide layout recommendations to ensure that each unit works seamlessly without overlap or signal interference, maintaining the integrity of your secure environment.

  5. Do I need to install additional equipment outside the meeting room for full coverage?
    Typically no additional equipment is needed. However, in areas with strong external interference, such as near a mobile tower, an outdoor unit can be added to reinforce coverage, and ensure that no unauthorized communications can penetrate the room.

  6. Does installation require modifying the room's structure?
    No, our devices are flexible in installation. They can be wall-mounted, ceiling-mounted, or placed on any surface without any structural modifications, offering hassle-free integration into your meeting room’s layout.

  7. Can the device run continuously without overheating during long meetings?
    Yes, the system supports continuous operation with built-in cooling systems and soft-start circuits, ensuring uninterrupted operation for 24/7 protection without the risk of overheating.

  8. Do you offer customization for secure meeting room needs?
    Yes, we provide OEM/ODM services to tailor power levels, frequency bands, and housing designs to fit your specific security requirements, ensuring that your confidential meetings are protected according to your unique needs.
