This low-profile flat-panel digital clock audio jammer suppressor suppresses the operation of the recorder through radiated noise interference, disrupting the audio input path, making the recorded content severely distorted or completely invalid.
It has a real clock display function and hides its actual purpose. The surface supports stacking light items (such as phones, pen holders, and paper documents, etc.) to achieve camouflage deployment.
T-SJ03 is equipped with a dedicated remote control (up to 7 meters away) to achieve contactless start/stop jamming function.
Instructions for use (please confirm before purchase):
- This device mainly supports traditional recording devices (such as digital voice recorders, tape recorders, etc.), not suitable for devices with AI noise reduction technology such as smartphones and wireless recording apps.
- To ensure the maximum jamming effect, the recording jammer must face the direction of the target device. The default direction is: facing the LCD display, the right side of the device is the signal transmission area, and the antenna points to the right.
- Make sure there is enough power before use. Do not connect the charger during use to prevent damage to the circuit or unstable interference output.
