The upgraded version of the anti-recording is the latest security protection device after several years of research and development. The portable can also be placed on a table, and its brushed alloy shell is pollution-resistant and wearable. The unit inside the case is located on the front of the case to ensure a stronger signal and better concealment.
If any voice recorder or mobile phone is checked to start voice recording,this anti-recording will randomly send out noisy signals to obstruct voice signals repressively,such voice recorder or mobile phone can only collect noisy and useless information
System characteristics:
1. Power switch and power regulation are integrated. The power adopts stepless knob, which is precise and convenient.
2. Adaptive silencing technology ensures the quietness in the use process.
3. The combination of host computer and expander forms shielding network, which has better shielding effect.
4. Large capacity 2200MAH battery, working for more than 8 hours.
5. Shielding distance is 2-3 meters.
6. It has the functions of over-voltage, over-current and over-heat protection.
7. Important components are all imported electronic components.
8. The output effective power is over 98%.
9. Injection-moulded shell, green and environmental protection.
