360° Desktop High Power Ultrasonic Audio Recording Jammer for Personal Privacy Protecting

360° Desktop High Power Ultrasonic Audio Recording Jammer for Personal Privacy Protecting

This recording jammer is a new high-tech product developed by our R & D personnel on the basis of existing products in combination with the characteristics of recording jammer. The product has beautiful appearance, simplicity and generosity.The product is equipped with 75 ultrasonic signal transmitting terminals. By adjusting the layout of three-dimensional signal transmitting terminals, the change from two-dimensional 360 degree to three-dimensional surround three-dimensional jamming is realized.

The three-dimensional spherical recording jammer is another new product of the recording jammer series. This product is a revolutionary reform in the application of recording jammer technology to further meet the needs of users.Suitable for various meeting rooms, meeting rooms and other occasions.

Product Features:

1.Larger jamming angle: it can realize three-dimensional jamming and no dead angle recording jamming.

2.Stronger jamming effect: compared with other similar products, its output interference signal power is greater and the number of ultrasonic signal transmitting terminals is more. Therefore, the noise signal picked up by the recording equipment is stronger and the jamming effect is stronger.

3.Longer jamming distance: compared with other products, the jamming distance is longer. Generally, the jamming distance of better recording equipment can reach about 1-3m, while the jamming distance of most recording equipment, such as mobile phones, can even reach more than 2-5m.

4.More kinds of power adjustment: the product is equipped with three power adjustment knobs to support stepless adjustment in each direction and realize centimeter level adjustment of jamming distance.

5.Wider coverage of equipment: the jamming rate of various mainstream recording equipment, such as Huawei, Xiaomi, iPhone, oppo, vivo and recording pen, is more than 98%.

Technical Parameters:

Application:

Operation room, confidential meeting room, office, bidding room, negotiation room and other places to prevent illegal recording.
