Don’t underestimate your phone: Even when it’s turned off, it can still be used as a spying tool. This Phone and Bluetooth Network Jammer can effectively block signal threats from mobile phones (including turned off), Wi-Fi, Bluetooth and other devices.
P-US-SJ3 has three independent channels, uses a built-in antenna to make it difficult to be discovered, and has a low-profile appearance that can be put into a coat pocket or placed on the corner of a table without being noticed.
You can use PC software to change the phone blocking device settings:
1. View the status and frequency range of each channel in real time, and adjust the parameters by simply clicking a button or moving a slider.
2. Support turning on/off channels individually. You can turn off unused channels to extend the device’s battery life. In addition, you can also increase the output power by jamming the same frequency band simultaneously through two channels.
3. Built-in 8 factory-preset frequency schemes, which can quickly switch to combinations such as “2G+3G”, “2G+Bluetooth” or “Full-band Jamming”.
4. Supports customized channel frequency, and each channel can set the start/end frequency separately.
