maybe you can also buy a video signal jammer

We know that military jammers are mainly used for military activities, and military jammers are generally designed for high output power, which can effectively interfere with cell phone signals in Video Signal Jammer and other frequency bands.In the face of serious personal information disclosure, we not only need to strengthen the protection of our own information, but also learn to prevent this from happening. Internet companies have jointly tried a new technology to smart transfer calls to harass calls, high-frequency phones. When the number dials the user's mobile phone in the suspicious phone database, it will automatically transfer to the and message platform, the phone will not ring, so as not to interfere with the user.

With the development of unmanned technology, wireless technology and artificial intelligence, signal blocker are commonly used in daily life, and some military jamming devices are installed in some places with high confidentiality to ensure data security.Military jammers are not only used in the military sector, but are also commonly used in other fields.In the research unit, research institutions to protect research data, they will put military jamming devices in the research room, on the one hand to interfere with internal personnel may steal data from the device, on the other hand to prevent outside attacks on scientific research equipment.

In a large conference room, in order to ensure that the conference is not disturbed during the conference, and the content of the conference is kept confidential, a high-power signal jammer is used to intercept the eavesdropping of the monitoring device. In prisons, in order to prevent criminals who are imprisoned from contacting the outside world and avoiding the possibility of certain prisoners escaping, military signal jammer is placed around the prison, and the connection with the outside of the prison is cut off. Only the corresponding signal spectrum communication is allowed to protect the security of the prison.
