Officer Blocking Traffic On Cell Phone

Secret research sites are prime targets for adversaries and foreign intelligence agencies to steal secrets. Install electronic monitoring, anti-theft, alarm and other safety devices according to actual needs, and strengthen prevention. Counterintelligence in secret places. Avoid eavesdropping by establishing a dedicated telephone network and using optical fiber transmission; build electromagnetic shielding rooms, shields, cell phone jammer , etc. to avoid wireless eavesdropping. Listen for vibrations by limiting the size of the sound source, implementing sound protection and pipe muffling, fixing mufflers, etc. Stealth technology is used to prevent spy satellites and high-altitude reconnaissance aircraft from stealing location photos; entry and exit security inspections, access control technology inspections, video surveillance and other management and control methods, as well as detection methods such as microelectronic equipment detection and metal detection, are used to prevent mobile phones and other photos from being stolen. For electromagnetic leakage and emission, low-leakage computers can be used in places where classified equipment is scattered and the degree of secrecy is high; places where classified equipment is concentrated and highly classified, electromagnetic shielding rooms and electromagnetic shielding cabinets. Devices that handle category and subcategory status information can be equipped with Officer Blocking Traffic On Cell Phone .

When installing Officer Blocking Traffic On Cell Phone in the corresponding site, we often need to install it according to the corresponding shielding range and surrounding environment, so how to judge the shielding range of the mobile phone signal jammer? There are mainly the following four points, together with mobile phone jammer manufacturers. Let us understand: the shielding range of the low-power mobile phone signal jammer is 0~50 meters, and the area is about 10~250 square meters (non-fixed value, according to the distance between the site and the base station, the shielding effect is different, the shielding range is mainly determined by the strength of the magnetic field. Decide.). Low-power mobile phone signal jammers are small shielding products that are only aimed at open areas and have a weak ability to penetrate walls. There is no base station within 500 meters, one test room is enough within 100 square meters, 2~3 sets are needed for lecture halls ranging from 200 square meters to 300 square meters; 1 conference room is installed within 100 square meters, and 2 sets are installed within 200 square meters. Set, 4 units flat pack. Installing more than 3 units in one area will form a honeycomb shielding effect and supplement the dead space.
