Plastic 85dB Acoustic Interference Audio Recorder Signal Jammer with 2m Shielding Distance
The Audio Recorder Signal Jammer SA-AJ001 effectively blocks mobile phones, digital recording pens, recorders, and any other sound acquisition devices. With shielding angles of horizontal 90°-120° and vertical 90°-120°, this acoustic interference device achieves up to 83% shielding effectiveness within a 2-meter radius.
Operating within a temperature range of -30℃ to 40℃, this AJ100 recording shield represents Sacon's independent research and development in high-tech safety protection. When illegal recording attempts occur, the device generates random noise signals that oppressively interfere with speech signals, ensuring only noise is captured by recording devices while speech information remains protected.
Ideal for corporate headquarters, confidential meeting rooms, operation rooms, business negotiation spaces, and any environment requiring speech information security.

Upon receiving the product, verify the package contains: one host, two expanders, two power adapters, and two connecting wires.
Hold the main unit and take out the special connection cable. Insert one end into the expander interface on the front of the main unit, and the other end into the interface on top of the expander.
After connecting both expanders, plug in the power adapter. Turn on the switch knob to activate the red indicator light on the main unit, putting the machine in standby mode. Press the unlock button on the remote controller to start the machine.
After startup, adjust the position and angle of the expanders according to your usage scenario. Ensure there are no obstructions in front of the expanders.
Test the expanders with recording equipment and adjust the power knob to achieve optimal shielding performance.
Refer to the placement principles diagram and instructional video for optimal expander positioning.
