As smart security technology advances and safety issues deepen, cell phone detection gates have become a common security device in our daily lives. How do these gates detect phones hidden in various ways?

Techniques like removing the phone’s battery, turning it off, or enabling airplane mode, can prevent signal detection devices from detecting signals emitted by phones, thus evading detection.

To address this, cell phone detection gates employ micro-residual detection and eddy current recognition technologies, which identify the unique substances present in items, thus differentiating between types and categories of objects. This detection technology is unaffected by the phone’s state, ensuring more accurate results.

Phones hidden inside the thigh, ankle, or armpit can bypass traditional detection equipment, allowing them to be carried into workplaces.

Cell phone detection gates achieve comprehensive human body scanning by using a mesh-like probe layout that divides the human structure into overlapping detection zones. This interactive detection accurately pinpoints the location of electronic devices, eliminating weak and blind spots in the detection area, and enhancing sensitivity and stability, effectively preventing false negatives.

Wrapping the phone in multiple layers of copper foil inside the innermost part of a clothing pocket can disrupt detection.

Depending on the level of environmental interference, cell phone detection gates use the world's most advanced technologies in metal classification, molecular detection, integrated rare metal micro-residue detection, eddy current technology, and analog-to-digital signal conversion to prevent false alarms and omissions, significantly improving anti-interference capabilities and ensuring more accurate detection.

In summary, no matter how phones are disguised, they cannot evade detection by cell phone detection gates, making these gates indispensable in venues where cell phone control is necessary.
