What is the interference distance of the recording jammer?

Corporate offices, important conference rooms, and party and government agencies will interfere with recording equipment by purchasing and installing recording jammers to prevent someone from illegally using mobile phones to record important meeting content or business in these special places. Confidential and other important information causes leaks.

How does a recording jammer interfere with the recording function of mobile phones and other recording devices?

The working principle of the recording jammer is to use ultrasonic waves to interfere with the recording equipment, so that the recording equipment only has noise information but cannot distinguish the voice information. Therefore, the recording jammer can play a role in disturbing the recording.

What is the interference range of the recording jammer? What area of ​​a conference room is suitable for a recording jammer to achieve effective recording interference?

Recording jammers can interfere with different ranges according to the power of ultrasonic waves. Normal portable recording jammers, such as FLY-1 jammers, can interfere with a distance of only two or three meters, and the interference angle is about 120°, and there can be no substantial objects in the middle.

High-power jammers, such as air purifiers, jamming boxes, etc., can interfere with a distance of 5-8 meters. When there is a substantial object in the middle, it can form a certain amount of reflection interference.

There is also a kind of jammer, which can be deployed in a distributed manner. A host can be placed, and the transmitting source can be distributed on the bottom of the conference table through 12 interfaces for interference.

At present, detection is a good protection method for recording equipment, detecting private places, secret meeting rooms, and recording equipment that may be placed. Simply relying on recording jammers to protect recordings cannot currently achieve particularly good results.
