Product Overview

The Multi-Function Outdoor Weatherproof, 12-Zone Digital Pulse Metal Detection, High-Sensitivity EOD Security Inspection Gate (also referred to as the Outdoor Weatherproof EOD Security Metal Detection Gate) is a high-reliability walk-through metallic contraband screening device specifically designed for complex outdoor environments and high-level security inspection requirements, constituting a core channel-type security inspection equipment for criminal technology, counter-terrorism emergency response and critical site protection. This product is deeply customized for tasks such as major event security, sensitive premises access control and crime scene perimeter security in harsh weather conditions including rain, snow, wind and sand, perfectly adapting to rigorous operational scenarios involving open-air deployment, prolonged continuous operation, high pedestrian throughput and precise alarm localization. By employing a fully waterproof structure design and advanced digital pulse detection technology, and dividing the portal detection area into 12 overlapping mesh detection zones with 100-level independent zone sensitivity adjustment, the system fundamentally resolves the operational pain points of traditional metal detectors, such as insufficient outdoor waterproof capability, weak resistance to environmental interference, high false alarm rates and inability to accurately distinguish contraband from everyday metal objects. It provides security personnel with non-contact, rapid and precise screening of concealed metallic contraband along with audiovisual zone localization, serving as a critical criminal technical equipment for constructing public security perimeters, ensuring the absolute safety of major events and maintaining the purity of criminal investigation scenes.

Technical Principle

The system is architected strictly based on electromagnetic induction and digital pulse signal processing technology. Under DSP control, transmitter coils embedded in both sides of the gate generate a uniform pulsed alternating magnetic field. When a person carrying metallic items passes through the detection channel, the metal objects induce eddy currents under the influence of the pulsed magnetic field, which in turn generate a weak secondary magnetic field. Receiver coils located within the gate structure capture this secondary magnetic field signal and convert it into an electrical signal.

The built-in high-speed Digital Signal Processor (DSP) performs real-time sampling, digital filtering and intelligent pattern recognition algorithms on the received signal. By comparing it against a pre-stored database of characteristic signals from various metal objects and environmental background noise, the system precisely distinguishes everyday items such as keys and belt buckles from contraband like firearms, knives and metallic components of explosive devices. The portal channel is virtually divided into 12 mutually overlapping mesh detection zones. Through joint phase and amplitude calculation of multi-channel received signals, the system accurately determines the location of the metal object on the body and triggers 360-degree visible audiovisual alarms via LED columns on all four sides. The entire detection process is non-contact and involves no harmful radiation to the human body, complying with relevant international standards for electrical safety and electromagnetic exposure. The technical design fully satisfies the statutory balance between human rights protection, throughput efficiency and detection reliability required in public security screening.

Core Functions and Compliance Operational Value

Fully Weatherproof Outdoor Continuous Operation Capability, Breaking Security Deployment Barriers in Adverse Weather
The gate structure adopts special sealing techniques and weather-resistant waterproof materials, achieving an overall waterproof protection rating that ensures stable continuous operation in exposed conditions such as heavy rain, heavy snow, high humidity and dust, without degradation of insulation performance or abnormal false alarms. This characteristic fundamentally overcomes the technical bottleneck that prevents conventional indoor metal detectors from being used outdoors in adverse weather, allowing security screening lines to be pushed forward directly to uncovered areas such as squares, roads and outer perimeters of venues based on practical counter-terrorism and EOD requirements, greatly enhancing deployment flexibility and adaptability during major event security and sudden incident response.

12-Zone Mesh Precise Positioning and High-Sensitivity Detection, Achieving Intelligent Distinction Between Contraband and Daily Items
The system divides the detection space into 12 mutually overlapping mesh zones with no physical detection blind spots. Sensitivity can be finely adjusted across 100 levels, enabling detection of micro-metallic objects as small as a paperclip. Crucially, each zone’s sensitivity can be set independently, allowing operators to flexibly reduce sensitivity in areas prone to common clothing metal interference, such as feet and waist, while maintaining high sensitivity in other zones. This ensures the detection of high-risk items such as firearms, daggers and explosive device metal components, while vastly filtering out invalid alarms from everyday metallic items like belt buckles, metal buttons and small keychains, significantly improving passage throughput and security resource utilization, meeting the practical requirements of balancing safety and efficiency in mass crowd screening.

Strong Anti-Interference and False Alarm Prevention Design, Ensuring Reliable Early Warning in Outdoor Complex Electromagnetic Environments
The system employs advanced digital pulse technology and electromagnetic compatibility optimized design, exhibiting extremely strong suppression capability against common outdoor sources of electromagnetic interference such as power substations, communication base stations and large electronic displays. Additionally, a unique built-in mechanical vibration compensation algorithm automatically filters out signal fluctuations caused by wind-induced shaking or inadvertent human collisions, completely eliminating false alarms triggered by environmental factors. This capability ensures that the equipment can continuously deliver stable and reliable security screening early warnings on the front lines of counter-terrorism emergency response, where conditions are characterized by temporary installations, dense crowds and changeable weather, providing trustworthy technical support for decisive action by security personnel.

Intelligent Networked Management and Data Traceability, Empowering Modern Security Command and Dispatch
The device has a built-in smart chip that pre-stores various detection programs suitable for different premises such as government buildings, sports venues and correctional facilities, and supports both Chinese/English menus and infrared remote control operation. Bi-directional infrared cross-beam counters achieve automatic and accurate entry/exit population counting.

This measure strictly maintains the material originality and evidence integrity of the crime scene investigation area, ensuring that examination work is free from external metallic interference and conforming to the specifications on scene protection and access control stipulated in public security crime scene investigation regulations.

Armed Suspect Manhunt and High-Risk Zone Control Scenario for Cases Involving Explosives and Firearms
During operations to address explosive threats or manhunts for suspects armed with firearms or carrying explosive devices, counter-terrorism or special police forces can rapidly deploy this detection gate at the exits of target buildings or at temporary checkpoints on key traffic routes. Dynamic screening of evacuated individuals or passing personnel is conducted to quickly determine whether weapons or metallic parts of explosive devices are being concealed, providing a mobile deployment screening means for narrowing encirclement, precisely locating targets and ensuring the safety of front-line officers.

Normalized Contraband Screening in Closed Facilities such as Correctional Institutions
At entrances and exits such as AB gates and visitor registration halls in prisons, detention centers and compulsory isolated drug rehabilitation centers, this equipment is used as a routine security screening device, enforcing mandatory screening on all individuals entering or exiting. Relying on zone positioning and high sensitivity, it focuses on detecting metal blades, homemade lock-picking tools, mobile phones and other prohibited metallic items, effectively cutting off the physical path for contraband smuggling into the supervised area, meeting the rigid equipment requirements of judicial administrative authorities for prison security management and the prevention of escapes and prison riots.

Core Technical Parameters

In terms of detection principle and system architecture, this metal detection gate utilizes digital pulse electromagnetic induction technology, with a high-speed DSP chip as the core processing unit for signal acquisition, noise reduction and intelligent identification. The portal is virtually partitioned into 12 overlapping mesh detection zones, achieving coverage without blind spots, and each zone allows independent fine sensitivity adjustment across 100 levels, capable of detecting a metallic object as small as a paperclip. Alarm localization is provided by built-in LED light bars on all four door columns, offering 360-degree dead-angle-free zone indication.

Regarding physical structure and waterproof performance, the gate features an integrally sealed waterproof design, capable of stable continuous operation under direct rain/snow exposure and high-humidity outdoor conditions, meeting all-weather deployment requirements. External dimensions are approximately H2220mm × W820mm × D522mm, with a passage space of H2000mm × W700mm × D522mm, accommodating standard foot traffic. The total unit weight is approximately 90kg, combining structural robustness with maneuverability for multi-scenario relocation.

For electrical and communication management, the power supply adapts to a global voltage range of AC 90V-250V, 50/60Hz, with a typical power consumption of only about 35W, ensuring energy efficiency. The operating temperature range is broad, covering -20℃ to 45℃, suitable for both severe cold and extreme heat. Built-in bi-directional infrared cross-beam counters automatically provide accurate counts of passers-through and alarms. A lightning-protected communication interface supports networking with host management software via RS-485 or Ethernet, enabling remote parameter setting, status monitoring, data querying and linked video capture, meeting the demands of intelligent security information management.

Regarding safety compliance, the equipment strictly adheres to relevant international standards for electrical safety, electromagnetic radiation limits and anti-interference performance. Magnetic field exposure is well below safety limits and poses no health risk to passers-through, including those with pacemakers or pregnant women. It also features excellent electromagnetic compatibility, causing no interference to surrounding electronic devices.

Compliant Field Application Cases

During a major international sports event, all competition venues and the opening/closing ceremony perimeter needed to withstand extreme peak pedestrian flow security pressure, while experiencing successive days of heavy rain during the event. The organizing committee’s security department deployed multiple units of this outdoor weatherproof metal detection gate in the uncovered buffer zones of main entrances. The devices operated stably around the clock under continuous rain without insulation failure or a surge in false alarms. Utilizing the 12-zone positioning function, security personnel quickly distinguished between daily items such as belt buckles and genuine contraband for the few individuals triggering waist-zone alarms, greatly accelerating passage speed and ensuring a balance between strict screening and audience experience. All metallic contraband was successfully intercepted outside the venues, ensuring the safety and smooth running of the event.

When a homicide occurred in a provincial capital city, criminal technicians needed to conduct detailed evidence examination in a city square greenbelt, where perimeter access control faced challenges of diverse personnel and disorderly equipment carriage. The on-site commander urgently set up this metal detection gate at the entrance, requiring all personnel entering the scene to pass through it. The system sensitively detected and stopped multiple individuals attempting to carry personal mobile phones, keys and other metallic items into the central scene, and was reactivated at the conclusion of the examination to prevent the risk of unintentional removal of physical evidence. The networked management platform recorded complete entry and exit headcount data and alarm logs, which were archived as an annex to the crime scene examination report. This standardized perimeter access control measure powerfully ensured the purity of the investigation area, secured the legality and probative force of collected trace evidence, and received subsequent recognition from procuratorial supervision.
