600 W Cell Phone Prison Jammer Devices GSM Scrambler Software Platform
Prison Jammer Description:
GW-J300JW High Power outdoor Water-proof Cell Phone signal jammer, implementing the most effective and reliable RF jamming technology to prevent the leak of confidential information or unwanted usage of cell phones, Wi-Fi devices and Bluetooth devices. module design, each band have independent power supply.it is easy to add new frequency and repair.
Monitoring Software Platform Introduction:
1. The Jammer Monitoring Software Platform allows users to monitor and control all Jammers through Internet, and all real-time alarm information feedback to the users immediately. So that users can stay at office to have all information of jammers working status, and adjust the Jammers to suit the operating environment of the installed area, greatly reduce the customer's maintenance workload.
2. The platform enables real-time display of all Jammers' output power, operating temperature, alarm information (including over-temperature alarm, under-power alarms, VSWR alarms, Door open alarms, etc.), and all information is specific to each Channel, real-effective, convenient and quick.
Prison Jammer Features:
1. Ouput power 600W, Jamming up to SIX different jamming modules.
2. Can customize these frequencies AM, FM Radio, LoJack 173MHz, VHF, UHF, Walkie-talkie, interphone, Wireless Toys , FM Radio, Remote Control, 27MHz, 49MHz, 433MHz,315MHz, 868MHz, 450MHz, iDEN, CDMA, GSM, GPRS, DCS, PCS, AWS, WCDMA,UMTS,3G,4G,LTE 700, LTE 800, LTE 2300, LTE 2600, GPS L1,GPSL2, Galileo, Compass, Glonass, WIFI, Bluetooth, Spy camera, WIMAX, UAV, Drone, etc.
