Library 808HI Portable Cell Phone Jammer GPS WIFI 3G Blocker 30dBm

3. Features

▲ IoT Network control with jammer management software, which can remotely monitor equipment voltage, current, power, equipment temperature and change working status;
▲ Can set up working hours(start time + end timn), saves energy
▲ Real-time display of equipment: voltage, current, power, equipment temperature (optional);
▲ The internal motherboard is with overvoltage and undervoltage protection functions. When the voltage reaches the upper and lower limits, the motherboard will be powered off and alarmed.
▲ The internal motherboard is with the temperature detection function. When the temperature reaches the upper limit, the motherboard is powered off and alarmed.
▲ With new SMD components, it has many advantages such as small size, outstanding performance and easy to use.



4. Main Function
■ Effectively shield each operator's mobile communication signals and WIFI signals of various standards;
■ Targeted shielding of the carrier's broadcast channel (ie, downlink channel), does not affect the normal operation of other electronic devices, and does not cause damage to mobile phones and human bodies;
■ Soft start circuit design;
■ Network management and control, the switch can be controlled by the intelligent shielding management system, and the switch can be turned on and off;
■ After networking, you can view the working status of the device in real time through software.
■ After the network is connected, upload the device's fault alarm in real time;
■ Can be used in networking or stand-alone;


5. Advantages of Intelligent Jammer over Conventional Jammer
▲ Can turn off by one-key clicking on the jammer management software
▲ During the nine working periods, the working time of each working period can be freely set by the user according to the actual use requirements.
▲ Report the working status to the intelligent jammer management system in real time, and the user will use each intelligent jammer device.
Work situation.
▲ Automatic fault alarm and cut off the power supply of the intelligent jammer's internal motherboard. It's not only safer, but also effectively extends the life of the intelligent jammer.
▲ Real-time display of the working power of all intelligent jammer devices.
▲ Subsequent maintenance and overhaul is very convenient. It only needs to judge the working status of the device through the icon color of the intelligent jammer device in the intelligent jammer management system. (Green means online, red means standby, yellow means alarm, and gray means offline.)
