An audio jammer is a device used to interfere with recording. It can prevent recording devices from working properly and protect conversation content from being recorded. These devices typically utilize ultrasound, white noise, or speech like interference technology to achieve their objectives.

Common types of audio jammers

1. Wireless optical detector: detects wireless pinhole cameras, quickly detects wireless pinhole cameras, and can last for 5 hours of battery power.

2. Signal detector: used to detect illegal electronic products such as eavesdroppers and pinhole cameras that rely on wireless signal transmission. The detection frequency range is wide, covering 2G, 3G, 4G, WIFI, Bluetooth, CDMA and other frequency bands.

3. Recording jammer: For example, the Bughonter Bda-3 is a portable and highly integrated confidentiality protection device that combines ultrasonic interference and voice sound interference, effectively interfering with digital analog recordings such as recording pens, mobile phone recordings, and magnetic tape recordings, as well as various voice eavesdropping devices such as wireless eavesdropping, wired eavesdropping, wall eavesdropping, and laser eavesdropping.

4. Mobile power type anti recording interference device: designed with the appearance of a regular power bank, the interference range is up to 5 meters, depending on the type of illegal recording and eavesdropping device. The device is equipped with a built-in battery and can work continuously for up to 2 hours.

5. Portable recording blocker Notebook-24: Disguising style, appearing in the form of a notebook during negotiation, interference types include ultrasonic interference and similar voice interference, used to interfere with mobile or fixed devices

6. Purifier anti recording interference device: adopts ultrasonic interference mode to ensure that voice information cannot be distinguished from the recorded signal, solving the problem of voice leakage caused by recording.

How to choose the appropriate audio jammer

When choosing a suitable audio jammer, you need to consider the following factors:

1. Interference range: Choose the appropriate interference range based on the size of the space you need to protect.

2. Interference effect: Different jammers have different interference effects on different types of recording devices. Choose an jammer that can effectively interfere with the type of recording device you are concerned about.

3. Portability: If you need to carry jammers frequently, choosing a lightweight and portable style will be more convenient.

4. Battery life: Choose a product with strong battery life based on the length of time you have used the jammer.

matters needing attention

When using an audio jammer, the following points should be noted:

1. Legitimacy: Before using a jammer, please ensure that the laws in your region allow the use of such devices to avoid violating the law.

2. Safety: Although most audio jammers are harmless to the human body, safety should still be taken into consideration when using them to avoid damage to the equipment.

3. Effect evaluation: Due to technical limitations, no anti recording device can guarantee 100% protection effect, so its protection ability should be reasonably evaluated when selecting.
