Anti recording and anti eavesdropping solutions in conference room
scenarios
1 Product Overview
A recording jammer designed specifically for conference room
scenes, equipped with a self-developed ultrasonic mixer and
utilizing ultrasonic band noise interference technology,
effectively shields various portable recording devices such as
mobile phones and recording pens, and the interfering audio cannot
be restored. The device supports wired/wireless networking and can
be used in conjunction with recording blocking devices to control
terminal usage. It can also be centrally managed through the
Meeting Guard platform. Ultrasonic noise technology is
imperceptible to the human ear and emits no harmful radiation.
2 Product Features
Ø Effective protection
Equipped with a self-developed ultrasonic mixer, it effectively
shields various portable recording devices such as mobile phones,
as well as eavesdropping devices installed in the table area
Ø No sense of security
Adopting ultrasonic band noise interference technology, effectively
shielding while being imperceptible to the human ear; No radiation
at all
Ø Flexible deployment
Under table/tabletop products and quantity combinations can be made
according to the size of the conference room and the size of the
conference table
Ø Networking control
Wireless/wired networking can be achieved through Bluetooth/RS232,
connecting up to 32 slave devices simultaneously. Management can be
controlled through control terminals, Meeting Guard network
management system, mini programs, or 315MHz remote controllers
