Mobile Phone Detection Gate

What is a mobile phone detection gate?

It is a walk-through screening gate that recognises the electromagnetic signature of electronic devices. Instead of alarming on every piece of metal, it filters out keys, coins and belt buckles and alerts only on smartphones, smart watches, earbuds, voice recorders and hidden cameras. Typical sites are schools, examination halls, meeting rooms and confidential facilities.

Four detection modes

  • Electronics mode: phones, smart watches, smart glasses, earbuds, recorders
  • Prohibited items mode: knives, firearms, metal pipes and canisters
  • Combined mode: both categories
  • All-metal mode: any metal, down to a coin

Where it detects

Detection covers the whole body regardless of clothing, whether the phone is on or off, with or without a SIM card, and wherever it is hidden — head, neck, shoulders, armpits, chest, back, waist, thighs or ankles. Detection accuracy is at least 99% with a false alarm rate of 5% or lower.

What it ignores

ID cards, bank cards, coins, belt buckles, metal buttons, zips, jewellery, keys, glasses, watches, pencil cases and umbrellas do not trigger an alarm.

FAQ

Can it find a phone hidden in clothing or a shoe? Yes. Coverage is full-body and the alarm shows the zone, so staff can re-check that spot.

Will keys and belt buckles keep triggering it? No. Electronics mode filters everyday metal.

Do side-by-side gates interfere? Each unit selects a clear frequency at startup, so interference is limited; still keep away from inverters and large motors.
