Portable Recording Shield Compact And Portable ,  It Can Be Used As A Mobile Phone Power Bank


1. Product overview


The WSD-L7C works by emitting ultrasound waves containing random noise that are inaudible to the human ear. When recording audio on devices like smartphones, these random noise signals are captured alongside normal speech sounds, rendering the recorded audio unusable. The same interference effect applies to audio information in video recordings. Since the random noise generated by ultrasound is inherently irreducible, the interfered audio cannot be reconstructed, thereby ensuring that original information remains protected from leakage and dissemination.

2. Product Features


(1) Anti recording portable power bank: It is both an anti recording device and a portable power bank;


(2) Remote control switch: Equipped with wireless sensors, it can achieve 1-20M remote control of device switch operation;


(3) Good anti recording effect: Our independently developed FPGA based ultrasonic band noise algorithm can effectively interfere with digital devices such as mobile phones and recording pens. The anti recording effect is at an advanced level, which can effectively ensure that conversations are not recorded, thereby ensuring information security;


(4) Wide range of application: The protection range of a single anti recording device is approximately a conical space, with an interferene range of about 15 square meters. The interference distance to the vast majority of digital products such as mobile phones is over 2 meters, forming a safe space where there is no need to worry about being recorded by others;


(5) Multiple functional devices: We tested iPhone, Huawei, Xiaomi OPPO,VIVO, Samsung, Nubia, Meizu, Nut and other new and old models of mobile phones have good interference effects. Sony, Samsung, Newman, Lenovo, Olympus and other recording pens have been tested and found to have good interference effects;


(6) Silent Guardian: The sound waves emitted by the anti recording device can only be received by digital products such as mobile phones and recording pens, but cannot be heard by humans. Compared to other anti recording devices, there is no buzzing noise, which can quietly protect the conversation environment from being easily detected by people.


3. Application scenarios


Any place for private conversations, such as confidential conference rooms, reception halls of procuratorates, courts, negotiation rooms, offices, etc.


4. Usage effect


Anti recording devices are only effective for digital products such as mobile phones and do not interfere with people because the human body does not receive ultrasound waves. Therefore, what mobile phone recordings record is noise, but people cannot hear it, so it does not affect normal conversation and communication, and even cannot detect that the anti recording device is working.
