Why Iphone voice recording difficult to jammer?

Because the three microphones record through different angles when the Apple phone records, effectively avoiding the linear interference of the recording blocker,

the common recording blocker on the general market is difficult to interfere with the recording of the Apple phone, or the interference effect is poor,

and the effective interference distance may not reach 1 meter. This is mainly because Apple's mobile phone has added a filter capacitor to the recording microphone system,

so that the recording function of Apple's mobile phone has a relatively strong anti-interference ability.

 

However, not all recording blockers are unable to take the Apple phone, the current recording interference equipment that can effectively interfere

with the recording function of the Apple phone exists, such as the newly developed new recording interference equipment. This category of equipment

covers more types of devices that can be interfered with, whether it is professional recording equipment such as high-quality voice recorders,

or Apple mobile phones can be effectively interfered with.

 

For example, the F14 recording jammer of XSH works by emitting ultrasonic waves with random noise that cannot be perceived by human ears.

When digital devices such as mobile phones record, these noises are recorded together with the sound of normal conversation into the digital device,

making the recorded audio invalid. For the audio information in the video shooting also has the same interference effect, because the ultrasonic

noise with noise is generated randomly and cannot be restored, so the audio after interference can not be restored,

so as to ensure that the original information is not leaked and spread.

Anti-sound recorder features

Good anti-recording effect

Our self-developed FPGA-based ultrasonic noise algorithm can effectively interfere with mobile phones, sound recorders and other

digital equipment, anti-recording effect in the world's advanced level, can effectively ensure that the conversation is not recorded,

so as to ensure the security of information.

Large scope of action

The protection range of a single anti-recording device is approximately a conical space, the interference range is about 10 square meters,

and the interference distance of most mobile phones and other digital products, including Apple mobile phones, is more than 1.5 meters,

which can form a safe space, and there is no need to worry about being recorded by others in this space.

Application for multiple brand devices

We tested iPhone, Huawei, Xiaomi, OPPO, VIVO, Samsung, Nubia, Meizu, Guan and other new and old models of mobile phones,

the interference effect is good, and tested SONY, Samsung, Newman, Lenovo, Olympus and other sound recorders, the interference effect is good.

Quiet guardian

The sound waves issued by the anti-recorder are only for mobile phones, recording pens and other digital products that

can receive but can not be heard by people. Compared with other anti-recording devices, there is no buzzing noise, and

the quiet protection of the conversation environment is not easy to be detected.
