Designed to address the threat of modern audio recording theft, the XL-021 handheld audio recorder jammer uses physical sound field interference technology to effectively block the pickup function of devices such as smartphones, audio recorders, and hidden cameras. It is suitable for environments with extremely high confidentiality requirements.
It integrates 21 ultrasonic transmitters, with a power 2-3 times that of similar products, effectively preventing mobile phones/recorders/video recordings.
It can accurately shield the audio. Once interference occurs, the language information cannot be restored. The sound is completely silenced before it enters the microphone.
The dual switch design can be manually or remotely operated, with a maximum operable sensing distance of 1-30 meters.
There are 9 transmitting holes on one side, and three sides can simultaneously emit ultrasonic signals. Each side is 90 degrees up and down, left and right, providing 270 degrees of all-round coverage, leaving no place for eavesdropping devices to hide.
This anti-monitoring recording jammer device is needed for:
• Confidential corporate meetings/executive offices —— effectively counteract hidden recordings by smartphones/watches
• Private place/confidential file room —— block professional-grade voice recorders/hidden cameras from picking up sound
• Prototype test sites in laboratories/R&D centers —— customizable partitions for protection ranges
• Financial transaction sites/legal mediation rooms —— ensure sensitive information is not leaked
