Ceiling Ultrasonic Microphone Jammer for Secure Conversations

Your conversations stay yours, even in shared spaces. This ceiling-mounted ultrasonic jammer disrupts hidden microphones and recording devices, so sensitive discussions remain private without changing how you work.

Installed above your meeting area, it operates silently in the background while you speak naturally, keeping attention on the conversation—not on the protection.

Protect every word without changing your routine

✅ Block nearby recording devices within ~3 meters for focused protection

✅ Keep meetings natural with silent ultrasonic operation

✅ Maintain control with remote ON/OFF up to ~20 meters away

✅ Cover conversation zones with 120° horizontal interference

✅ Blend into ceilings for discreet, non-obtrusive installation

✅ Run continuously for 4–5 hours during key discussions

✅ Reduce risk of leaks from phones, dictaphones, and hidden mics

The system uses microprocessor-controlled ultrasonic transducers to emit signals above human hearing. These signals interfere with microphones in smartphones, recorders, and hidden devices, making captured speech difficult to understand on playback. You continue speaking normally while the protection works quietly in the background.

Install it directly into a suspended ceiling above desks or conference tables for best coverage. It activates as soon as it’s powered, and the included RF remote (433.92 MHz) lets you switch jamming on or off from across the room. LED indicators provide clear status feedback at a glance.

This fixed, ceiling-integrated design stays out of sight and avoids the distraction of tabletop units. There are no loud masking noises, no clutter on the table, and no need to reposition devices during meetings—just consistent, discreet coverage where discussions happen most.

Suitable for conference rooms, executive offices, negotiation spaces, and any indoor area where conversations need added privacy from unauthorized recording.

Keep sensitive conversations private without interrupting how you work.
