to know some information of cctv camera jammer device

In excessive media today, developed communications network impact is not only the university classroom, such as meetings, reunion order of various social routine activities are affected by bow clan brush weibo ‘letter. In the classroom, teachers and students should reach a consensus that the teaching order should not be destroyed, and it is obvious that students playing with mobile phones signal blocker are illegal.Russian use of jamming in situations short of all-out war would reduce their effectiveness during an actual war, as U.S. and Allied forces study the signals and figure out ways to overcome them and field improved, jam-resistant system.
