Remote Monitoring All in One 8 Band Cell Phone Signal Jammer for 2G 3G 4G GPS
The device GW-JB55WM is easy to install, interference distance, the effect is stable. The rear of the host is equipped with a high-efficiency heat sink to protect long-term working. This product is equipped with remote monitoring system. Users can control and monitor all jammers through the network. They can receive real-time status of the equipment and timely alarm information. The monitoring platform can display the power, temperature and alarm information of the equipment in real time, including high temperature alarm, low power alarm, standing wave alarm and door opening alarm, etc. The platform allows users to modify the background image of the login page and upload their own logo.Therefore, users in the office can understand whether the equipment is working properly, which greatly reduces the maintenance workload.
GW-JB55WM Jammer has 8 pcs of jamming modules to support 8 band frequencies shielding. Of course, it’s built-in antennas and the jammer looks like a LED Panel Lamp. No more complex buttons, it can work directly when you plug-in with power. With intelligent chip, it can shield all kinds of wireless signals like EGSM900, DCS1800, WCDMA2100, LTE2600, WiFi etc. With metal shell, the device can work in various complex environments for a long time to achieve uninterrupted shielding effect. The aluminum material shell makes sure the device to work in low temperature without so much noise. The greatest advantage is waterproof.
If you are looking for efficient units to jam phone signal in places exam room, churches, temples, gas station, cars, train or many others, GW-JB55WM Jammer is definitely qualified for all the purposes using. As a jammer with well-built design and high level of reliability, users are given more options what signal to jam and where to use the jammer.
Only interfere downlink frequency of mobile system,without disturbing norrmal working of Base Station; Imported elements, Slow start up design of circuit. These elements can maintain the stable operation condition with high integration,
Perfect self-protection function, when the equipment overheating, over Output power, VSWR alarm, Jammer will automatically turn off the faulty module to avoid Jammer damage.
