Worried about the phone in your pocket eavesdropping on your conversations? Check out this all-in-one wireless signal and recorder jammer system that integrates multiple jamming technologies. It can be cleverly hidden on the ceiling in the center of the office, controlled by a remote control, and can freely switch jamming modes to provide strong protection for voice information.
The audio jammer has three jamming mechanisms:
1. Ultrasonic pickup jamming
Built-in 120 transmitters (single power 90 dB), which can suppress highly sensitive microphones (smartphones, recorders, etc.) at a distance of up to 15 meters. Prevent spy devices from recording voice information.
2. Low-frequency acoustic shielding
Equipped with 5 low-frequency acoustic speakers, it can actively emit “chorus-style” jamming sounds. This audio will be mixed with the human voice into the recording device, making the voice content blurred and unrecognizable when it is played back.
3. Block wireless communication
The device supports simultaneous suppression of 10 mainstream frequencies to prevent all data leaks based on cellular networks and the Internet. Such as:
- CDMA / 3G / 4G LTE
- Wireless network: Bluetooth, WiFi
- SMS and mobile data transmission
UL120 has 4 operating modes:
- Ultrasonic interference mode – activate 120 ultrasonic transmitters to interfere with recording devices
- Low-frequency acoustic suppression – enable speakers to confuse voice
- RF interference mode – shield mobile phones and wireless communications
- Comprehensive protection mode – activate all functions at the same time, comprehensive shielding
