Is there a machine that detects mobile phones and is placed at the gate of the school to prohibit students from bringing mobile phones? How much is the price?

There are mobile phone signal detectors or mobile phone security gates. The mobile phone signal detector can detect when the mobile phone is in the standby state, but these two devices cannot detect the mobile phone that has been turned off. The most convenient way is to use a wifi jammer, so even if it is not detected, students can't use it when they turn on their mobile phones, because the signal and the network are blocked by the wifi blocker.
