When a business meeting is held, no one can guarantee that in an important meeting, one's own competitors will not install some equipment for listening. In this way, one's own company will also be threatened with the disclosure of trade secrets.
An effective way to prevent opponents from recording is to use a recording blocker to block mobile phone voice recorders. The recording muffler generates random noise signals, and produces suppressive interference to the voice signal, so that only noise information is picked up by the recording device.
Therefore, the voice message cannot be heard. The cell phone jammer adopts security encryption processing, and effectively prevents post-recovery by mixing high and low frequency audio sources.
Advantages of recording jammer
Good concealment: The use of audio can be used as a corporate product for appearance, which is exactly the same as an ordinary audio on the surface. At the same time, we increase the social background noise, which is extremely concealed. Greater shielding effect: For products on the market, the shielding range is greater. Therefore, the stronger the noise signal series of the recording device picked up, the stronger the shielding effect.
There are many interference devices: For the current mainstream recording equipment, the recording blocker can shield its coverage can reach more than 85%. For iPhone series, Huawei mate, Honor, OPPO, VIVO, Samsung, Nubia, Meizu, Nuts, etc. Mobile phone interference effect is good.
Long interference distance: Compared with some other enterprise products, its shielding distance is farther. Generally, in this case, the shielding distance of better recording equipment can reach about 1-2 meters. The anti-recording device is effective on 95% of mobile phones. The interference distance is more than two meters, and the interference distance to 60% of mobile phones is more than 5 meters.
The recording muffler does not interfere with people, because the human body does not receive ultrasound, so the mobile phone records all noise, but people can not hear it, so it does not affect the normal conversation and communication, and it is even impossible to detect the work of the recording muffler. Applicable places: Leader's office, confidential meeting room, jun war room, business negotiation room and other places that prevent recording.
