All 1 models in this category
What this category solves
- Phones and recorders cannot be reliably confiscated at the door
- Audible masking noise makes a meeting impossible to hold
- One unit cannot cover a long table or a large room
- There is no record of whether protection was active during a session

Who it is for
- Organisations holding commercially sensitive negotiations
- Facilities protecting information in fixed meeting rooms
- Security managers networking several rooms under one system
- Confidential reception and negotiation areas
What the range gives you
- Ultrasonic mixing across 72 probes, inaudible to people in the room
- No electromagnetic radiation, complying with national safety industry standards
- Up to 32 units linked by Bluetooth or RS232 for a large room
- Meeting Guard management with status monitoring and historical traceability
- Interference beyond 2 m against a Huawei Mate 40 at 70 dB
Typical scenarios

Ultrasonic Recording Protection FAQ
Can people in the room hear it
No. It uses ultrasonic noise interference, which is not perceptible to the human ear.
Does it emit electromagnetic radiation
No, which is why it is usable where RF jammers are restricted.
How far does the protection reach
Over 2 metres against a Huawei Mate 40 and over 1.5 metres against an iPhone 12, measured at 70 dB.
Can we cover a large meeting room
Yes, up to 32 units can be linked by Bluetooth or RS232.
Is there a record of use
The Meeting Guard network management system provides status monitoring and historical data traceability.
Should we also sweep the room beforehand
Ideally yes. A non-linear junction detector finds a device before the meeting; this stops one that was missed from recording anything useful.
