Wireless Remote Control Equipped with a wireless sensor remote control, it can remotely turn the device on and off, adjust the frequency of the shielder, with a sensing range of 1-20 meters.

Measured Shielding Range of 1-5 Meters The shielding range for Apple phones is approximately 1 meter, while Android phones have a shielding range of 4-5 meters.

The working principle of 65 is to emit ultrasonic waves with random noise that cannot be perceived by human ears. When digital devices such as mobile phones record, these noises are recorded together with the sound of normal conversation into the digital device, making the recorded audio invalid. The audio information in the recorded video also has the same interference effect. Since the noise with ultrasonic noise is generated randomly and cannot be restored, the audio after interference can not be restored, so as to ensure that the original information is not leaked and transmitted.

It has a reliable industrial design and a convenient interactive interface

Piggyback repeater (same frequency)

● Flexible working mode TDMA time division multiple access technology is adopted. It supports co-frequency relay, and when the handset is out of the relay coverage, it will not affect the communication with the surrounding users. It supports one DMR heterogeneous frequency relay and is compatible with traditional usage modes. There is no duplexer limitation, and the frequency point selection is flexible. ●Compact size and flexible use Piggyback-ready, removable battery, can be used in a fixed place, with a power of up to 25W.

Equipped with dual switches, allowing users to flexibly choose to activate or deactivate specific shielding functions based on their needs

Specifically designed to counter various positioning and tracking systems, enhancing personal privacy and security

Handheld mobile phone GPS satellite signal interceptor is specially designed and produced by our factory according to the inconvenience caused by the current flooding of satellite positioning (car positioning, mobile positioning, wifi network positioning, etc.) to some confidential units and individuals. In the use of this product within 1-10 meters, the GPS/ base station /WiFi positioning signal is effectively truncated, so as to form an effective protection area, so that your whereabouts do not worry about being tracked.

Wireless Remote Control Equipped with a wireless sensor remote control, it can remotely turn the device on and off, adjust the frequency of the shielder, with a sensing range of 1-10 meters.

Measured Shielding Range of 0.5-2 Meters The shielding range for Apple phones is approximately 0.5 meters, while Android phones have a shielding range of 1-2 meters

This product supports cross-network interconnectivity and all value-added services in GSM and WCDMA networks. This product is a brand new end-to-end voice encryption and decryption equipment suitable for the mainstream technology of 4G network and compatible with 3G and 2G network technologies. It has the ability of anti-AMR compression coding and anti-RPE-LTP compression coding. It has high speech intelligibility and good voice quality, and there is no problem of network compatibility.

Measured Shielding Range of 1-5 Meters When a microphone is directly facing the shielder, the effective distance varies with different brands of smartphones and recording pens.

Multi-Angle Adjustable Independent Switches The device can independently control the switches of the four-sided combined emission terminals to meet the needs of different scenarios.

The 66 recording shield product produces suppressive interference to the speech signal through random acoustic signals, so that the digital recording equipment only has noise information, but can not distinguish the voice signal. Through randomly generated sequences, the original information cannot be restored from the recorded signal, thus ensuring the security of voice messages.
