Nowadays, the demand for smart home systems is increasing. Devices connected to the Internet are called "Internet of Things" and are everywhere. In this case, all connected household goods can become people’s eyes and ears in your own home, exposing your privacy to the government. In this case, only portable wifi jammer or similar thrusters can solve your problem.
There are also unmanned aerial vehicles and unmanned aerial vehicles (UAV) controlled by 2.4G signals that can also be used to monitor you. Although most of these robots are operated with the help of remote control, be absolutely sure that unmanned robots will not be used for surveillance in private meetings, business operations or any other events in your life, but you must use remote Control-wifi jammer.
