How does a cell phone detector detect a student carrying a cell phone?

First, what the editor said to you today is a security gate, firstly, a metal gate, a mobile door, a contraband door, then what I usually see is a metal door, mainly in the subway station, bus station, etc., which is a door for any metal item we carry, and we call the police as long as we pass.

Metal security screening gate.

This commonly known metal security screening gate is based on the use of magnetic compatible dual detection source technology, which produces alarm devices when a human being carries a metal object through, and which accurately detects metal articles on the body or in a handbag or articles containing metals, such as belts, buttons, zippers, keys, control knives, weapons, metal products, electronics and other metal-containing items, which can be reported to the police as long as the metal is in the body or in a handbag.

Cellular Detection Gate

The first is to detect whether the security officer carries electronic products such as a mobile phone, and if the security officer carries a mobile phone or other electronic products, such as notebooks, tablets, etc., the mobile phone detector will have a light and sound alarm, and the main page will show the location of the alarm, thus alerting the security officer to which it will focus. And mobile phone detection doors can also be used to call the police regardless of whether the phone is turned on or off.

Cellular detection doors are detected mainly by vortex detection and electromagnetic identification sensors, microdiscretion, precision filtering, limited metaanalysis, self-adaptation, combined analysis of multi-metal substances and algorithms for the identification of differences between mobile phones and other metals in the security screening gate-checking process, and the exclusion of non-cellular items.

Cellular detection doors are primarily aimed at confidential locations where cell phone communications are prohibited, where cellular signals are detected/interrupted and cellular communications are detected and stopped. The advantage of this equipment is to conduct small-scale mobile signal monitoring and control in the area of involvement, and to use technical means to locate the cell phone and target real-time control through monitoring of cellular signals in the area of involvement. No additional control lines are required, they are portable, mobile, ready to deploy and easily installed.

So it is clear from the above that the mobile device detector door can detect whether the student is carrying a cell phone, because the cell phone detector can remove other metal items to report to the police only on the phone, and if the school rules that students are not allowed to carry a mobile phone, the mobile phone detector is a good option!
