Economical Smart Phone‑Detection Security Gate

1 Product Introduction

The smart phone‑detection security gate adopts MCU‑DSP or FPGA control circuitry to drive low‑frequency and high‑frequency electromagnetic transmission and reception. Its controller performs complex algorithm processing including signal amplification, filtering, feature extraction and signal pattern recognition. Based on pre‑established MCU data models, it can filter out ordinary personal metal articles and detect carried smartphones, electronic bracelets, voice recorders, miniature photography equipment and other electronic devices. It is applicable to schools, examination halls, marking rooms, meeting rooms and other premises.

This product effectively eliminates interference from ID cards, bank cards, coins, belt buckles, metal buttons, zippers, jewelry (rings, necklaces etc.), keys, eyeglasses, watches, stationery boxes (containing pens, rulers, compasses), umbrellas and similar items. It accurately identifies smart bracelets and electronic devices with photographing or communication capabilities. In addition, it can detect and alarm against controlled knives, firearms, metal tubes, metal canisters and other contraband articles.

This is an economical‑grade model. “Economical” means the display panel is downsized from a 29‑inch large screen to a 15.6‑inch or even smaller screen. Moreover, its door panels are thinner and lighter than the standard version. Consequently its anti‑vibration performance is reduced, so installation sites must minimize vibration exposure.

2 Technical Features

‑ Four detection modes: Electronic‑device mode, contraband mode, contraband + electronic‑device mode, full‑metal mode.

‑ Under electronic‑device mode: Detects smartphones, electronic watches, smart glasses, Bluetooth earbuds, voice recorders and other electronics. Detection for smart glasses and earbuds is an optional feature.

‑ Detection coverage: Reliable detection regardless of winter/summer clothing; works for both feature phones and smartphones, whether powered on/off or with/without SIM cards. It detects devices placed on the head, neck, shoulders, armpits, chest, back, waist, hips, inner/outer thighs, calves, feet or ankles.

‑ Strong anti‑interference capability: The controller supports environmental self‑learning. Metal tables, fences or mobile‑phone jammers located more than 0.5 m away from either side of the gate will not interfere with detection. However, alternating‑field interference sources cannot be avoided; keep clear of such environments.

‑ Web‑based debugging: Configure parameters and view data via web browser.

‑ Windows‑compatible: Supports remote log collection, remote control and remote debugging over wide‑area networks.

‑ LAN management platform: Manage multiple units simultaneously over local area network, supporting parameter configuration and data statistics & query.

‑ Detection accuracy: ≥99 % for smartphones; false‑alarm rate ≤5 %.

‑ Passage direction: Supports one‑way and two‑way pedestrian flow and inspection.

‑ Throughput rate: ≥45 persons per minute.

‑ Voice broadcast: Customizable voice alarm prompts.

‑ Basic data acquisition (optional camera): Automatically capture face snapshots, detection logs, alarm events, date‑time stamps and other pedestrian data.

‑ Rich interfaces: RJ45, RS232, USB, 3.5 mm audio, HDMI, DP.

‑ High sensitivity: In full‑metal mode, can detect objects as small as a one‑yuan coin.

‑ Alarm visualization: 10‑inch LCD shows human‑body alarm zones, complemented by high‑brightness LED strips to indicate alarm positions.

‑ High stability: Wide environmental adaptability. No re‑calibration required after repeated relocation. Suitable for semi‑outdoor deployment (rain shelter tent required). Good wind‑resistance and shock‑resistance.

‑ Multi‑zone alarming: 15 independent detection zones for precise localization of alarm triggers.

3 Technical Principle

Building upon conventional security‑gate technology, this smart security gate employs advanced electromagnetic‑signal processing to sense target objects. It supports metal‑triggered alarms as well as intelligent filtering of daily wearable metal items.

Traditional security gates trigger alarms when metal disrupts the magnetic‑field balance between the two door panels. This mechanism is fast and efficient but can only measure signal magnitude without sophisticated signal analysis.

The smart security gate captures full‑time‑domain signal waveforms as objects pass through. Each article generates a distinctive signal signature, which forms the foundation for intelligent classification. Combined with AI deep‑learning algorithms, smart classification detection is realized.
