FAQ on Ultrasonic Audio Jammer AJS-333
Q1. Can AJS-333 100% jam the audio recording from authorized voice recording devices?
Any of this type of con-tactless Audio Jammer, it is difficult to promise 100% jamming effectiveness. Because factors as distance, angles, power consumption, shielding affect the performance. But the performance of iSecus Audio Jammers is far superior to many other similar products in the market, concerning jamming effect, quietness and user-feeling experience, workman craft and quality. They are designed for high-end users. You will get what you pay.
When using ultrasonic audio jammers, it is necessary to understand the physical properties of ultrasonic and its limitations. Ultrasonic wave has the characteristics: When encountering hard objects, it will be reflected. When encountering software objects, it will be absorbed.
Therefore, please try to avoid special obstacles between the jammers and target recording devices. Meanwhile, please consider suitable qty of jammers and proper placement to get the best protection of the conversation.
Q2: What is Ultrasonic Jamming Technology
Answer: Based on CPLD/FPGA Chip embedded with encrypted algorithm, it generates ultrasonic mixing data model and exports ultrasonic signals, forming a harmonic effect to deceive the recording device. The microphone/pick up can only receive the harmonic ultrasonic signal generated by jammer, can not pick up the normal voice signal. The recorded audio only plays noise, its content cannot be identified, and cannot be analyzed using technical means (the noise completely covers the speech).
Q3. Is the ultrasound technology harmful to human health?
Ultrasonic Technology has been widely used in many applications such as parking radar and B-ultrasonic. Ultrasonic is essentially a mechanical wave and does not radiate itself. However, it has strong directionality and high energy. When using it, try to avoid pointing it directly at the ear. It would cause ear pressure discomfort.
Q4. What are the main advantages and disadvantages of ultrasonic jamming technology, compared to white noise technology?
Advantages:
Ø Silent and Safe Jamming
Ø Better User Experience
Ø Wide Applications
Disadvantage: Cost is much higher!!!
