Audio Recorder Jammer (privacy guard)    

WSJS-L7

Brief Introduction

With the development of information society, audio and video information go virus. Personal privacy, business secrets and other information may be leaked through conversation, especially that confidential conversation. How to protect the conversation content from being obtained by others?

WSJS-L7 emits ultrasound with random noise that can't be perceived by human ears. When recording on digital devices such as mobile phones, the noise and the sound of normal conversation are recorded into digital devices together, making the recorded audio invalid. It also has the same interference effect on the audio information in the captured video. Because the noise of ultrasound with noise is generated randomly, it can't be restored Therefore, the audio can not be restored after being interfered, so as to ensure that the original information will not be leaked and spread.

Features

Good anti-recording effect

With ultrasonic noise algorithm based on FPGA can effectively interfere with mobile phones, voice recorder and other digital devices, can effectively ensure that the conversation is not recorded, so as to ensure the security of information;

Wide effect range

The protection range of a single anti recorder is similar to a conical space, and the interference range is about 15 square meters. The interference distance to most mobile phones and other digital products is more than 2 meters, which can form a safe space, in which there is no need to worry about being recorded by others

The device is easy to operate, with push-button operation and high-brightness LED display, regardless of whether the user is trained or not.

For multiple devices
