What is the effective range of a recording jammer?

Recording jammers are often used in corporate offices, important conference rooms, and government agencies to prevent the unauthorized use of mobile phones or other recording devices to record confidential meetings and sensitive information. These jammers interfere with the recording function of such devices.

How do recording jammers interfere with recording devices?

Recording jammers use ultrasonic waves to disrupt the operation of recording devices, making them unable to distinguish voice information and only generating noise. By utilizing this principle, recording jammers can effectively interfere with the recording process.

What is the interference range of recording jammers? Which area of ​​the conference room is suitable for effective interference?

The interference range of a recording jammer depends on the power of the ultrasonic waves it emits. Portable recording jammers like FLY-1 usually have a limited interference distance of two to three meters, and the interference angle is about 120°. It is important to note that no substantial objects should block the interference line.

Higher-power jammers, such as air purifiers or jammer boxes, provide an interference range of 5-8 meters. When there are a large number of objects in the environment, they cause reflected interference.

In addition, there are distributed recording jammers available. These systems consist of strategically placed mainframes with transmitters distributed across the bottom of the conference table via 12 interfaces, ensuring comprehensive jamming coverage.

Currently, relying solely on recording jammers to protect recordings may not provide optimal results. It is recommended to use detection methods such as scanning for recording devices in private areas, secret meeting rooms, and potential locations where recording devices may be placed to enhance protection.
