Afraid of incomplete shielding? The signal environment is complicated, and the budget is not enough? Afraid of being destroyed and the machine's lifespan is short? Just want to shield one signal, afraid of affecting other frequency bands? Afraid that the jammer will be discovered by others? Afraid that the jammer is too ugly to affect the indoor environment ?
Recording jammer is a device used to shield recordings in a specific environment. It can effectively interfere with digital and tape recorders, video cameras, and audio recording devices. It can effectively interfere with digital voice recorders and tape recorders with a frequency of 100HZ-20000HZ. By outputting white noise outside the frequency range of human hearing, the voice recorder or tape recorder can only record a piece of "humming" noise, and the conversation content of the speaker cannot be recorded, and the recorded voice cannot be restored after the sound post-processing. The sound (because the sound captured by the recording device is only noise). So as to effectively protect the conversation content from being secretly recorded. At the same time, the recording equipment jammer does not emit any visible sound during work.
The latest development of recording jammer has core technology, and its shielding and hiding effects are better than domestic and foreign products. This equipment can effectively interfere with digital and tape recorders and various eavesdroppers with a pickup frequency of 100Hz-20000Hz. It can only record the "buzzing" noise, and cannot record the conversation content of the speaker. The recorded sound cannot be restored after post-processing, thus effectively protecting the dialogue content from being leaked.
The newly-developed L7B recording jammer is upgraded on the basis of the original equipment. The FPGA-based ultrasonic noise algorithm eliminates the high-frequency noise of the old equipment. It adds the information of various brands of mobile phones and recording equipment that have been on the market in the past two years. The new recording equipment and mobile phone recording have very obvious effects.
MDPB-L7B recording jammer is used to interfere with any recording equipment around, the interference distance can be up to 10 meters, depending on the performance of the recording equipment. In addition, it also has an acoustic interference mode, which randomly generates a noise background, which is similar to human voice noise that can be adjusted in volume. If your conversation is recorded by a recording device, the recorded sound record contains a variety of mixed sounds, making it impossible to hear any of them.
Recording jammer is a device that can prevent any recording and eavesdropping equipment. By emitting ultrasonic waves with random noise that human ears cannot perceive, when digital devices such as mobile phones are recording, these noises are recorded into the digital device together with the sound of normal conversations, making the recorded audio invalid. Audio information also has the same interference effect. Because the noise with ultrasonic noise is randomly generated and cannot be restored, the audio after interference cannot be restored, thus ensuring that the original information is not leaked and spread.
Recording jammerProtect your meeting room or other negotiation spaces from being recorded or transmitted. Ultrasound will interfere with the sound pickup film of all current smartphones (including Apple, Samsung, etc.) and other micro-phones, making illegal recording equipment unable to work. Acoustic suppression of low-frequency "mixing" makes the recorded sound sound like a mixed noise and cannot be separated by technology. Protect voice information during meetings or conversations from being leaked. It is completely suitable for any environment and will not attract attention. Sound suppression adjustable volume. Create a comfortable environment for the negotiation process. Multiple interference shielding modes provide you with the highest security negotiation and negotiation.
