Walk Through Metal Detector Manufacturer in China
Securina Detection System Co., Limited is a walk-through metal detector manufacturer and supplier in China, based in Shenzhen, Guangdong. The company develops and manufactures walk-through metal detectors (WTMD) for security screening at airports, prisons, schools, customs checkpoints, government buildings, factories, stadiums, transportation facilities and other controlled-access locations.
Securina's walk-through metal detector product range includes different detection-zone configurations, portable models and outdoor-capable configurations designed for different security screening requirements.
In addition to standard walk-through metal detectors, Securina provides OEM and ODM manufacturing services for security equipment distributors, system integrators, project contractors and international security brands.
What Is a Walk Through Metal Detector?
A walk-through metal detector, also called a WTMD, walkthrough metal detector, security metal detector gate or metal detector door, is an electronic security screening system designed to detect metallic objects carried by a person as they pass through the detection zone.
Unlike a handheld metal detector, which is operated manually, a walk-through metal detector allows people to be screened as they pass through a fixed detection portal.
A typical walk-through metal detector consists of:
-
Detection panels
-
Electromagnetic detection coils or sensors
-
Control unit
-
Alarm indicators
-
Display
-
Power supply
-
Detection-zone configuration
-
Optional remote control and communication functions
Walk-through metal detectors are commonly installed at entrances where a continuous flow of people must be screened efficiently.
Securina Walk Through Metal Detector Manufacturer
Securina focuses on the development and manufacture of security screening equipment, including walk-through metal detectors.
Its WTMD portfolio is designed to cover different security screening requirements, from basic entrance screening to higher-zone personnel inspection.
Securina's walk-through metal detector models include:
-
SA200
-
SA300
-
SA300C
-
SA300C-Plus
-
SA300S
-
SA600
-
SA300P Portable Walk Through Metal Detector
Different models provide different combinations of detection zones, sensitivity adjustment, environmental protection and application configurations.
The appropriate model depends on factors such as:
-
Security level
-
Required detection sensitivity
-
Number of people screened
-
Indoor or outdoor installation
-
Available entrance space
-
Required detection zones
-
Project budget
-
Integration requirements
Walk Through Metal Detector Detection Zones
One of the most common specifications buyers compare when purchasing a WTMD is the number of detection zones.
Depending on the model, Securina offers configurations ranging from entry-level multi-zone systems to higher-zone walk-through metal detectors.
Common configurations include:
-
6-zone
-
8-zone
-
24-zone
-
33-zone
-
45-zone
-
60-zone
The number of zones refers to the number of vertical or segmented areas in which the system can indicate the approximate location of a detected metallic object.
More detection zones can provide more detailed alarm localization.
However, a higher number of zones does not automatically mean that a detector is suitable for every application. Buyers should evaluate the complete system, including detection performance, sensitivity, stability, software functions, environmental conditions and after-sales support.
Securina SA600 60-Zone Walk Through Metal Detector
The SA600 is one of Securina's higher-zone walk-through metal detector models.
It is designed for applications where more detailed detection-zone localization is required.
The SA600 uses DSP-based technology and supports automatic calibration. Depending on configuration, it can be supplied with different detection-zone options.
Typical applications include:
-
Airports
-
Customs
-
Prisons
-
Government buildings
-
High-security entrances
-
Public venues
-
Transportation facilities
The SA600 can be considered when a project requires a higher-zone WTMD rather than a basic entrance metal detector.
Securina SA300S 45-Zone Walk Through Metal Detector
The SA300S is a multi-zone walk-through metal detector designed for security screening applications requiring detailed alarm localization.
The model can be configured with different zone options according to project requirements and is available with enhanced environmental protection configurations.
Potential applications include:
-
Prison entrances
-
Airport security
-
School entrances
-
Government facilities
-
Event venues
-
Factory entrances
-
Public buildings
For projects where environmental conditions are a consideration, an IP-rated configuration may be selected when available for the specific product configuration.
Securina SA300C Series
The SA300C and SA300C-Plus are multi-zone walk-through metal detectors intended for general security screening applications.
They can be used at:
-
Schools
-
Offices
-
Factories
-
Prisons
-
Government facilities
-
Public venues
-
Transportation entrances
The SA300C series provides an option for customers who require multi-zone detection without necessarily selecting the highest-zone configuration.
Portable Walk Through Metal Detector
For temporary security checkpoints and locations where permanent installation is not practical, Securina also offers portable walk-through metal detector solutions.
The SA300P is designed for portable security screening applications.
Portable WTMD systems can be useful for:
-
Temporary events
-
Exhibition halls
-
Outdoor checkpoints
-
Construction sites
-
Temporary entrances
-
Emergency security screening
-
Mobile security operations
Portability allows security teams to establish screening points in different locations as required.
How Does a Walk Through Metal Detector Work?
A walk-through metal detector generates an electromagnetic field within the detection area.
When a person carrying a metallic object passes through the detector, the interaction between the electromagnetic field and the conductive object produces a detectable signal.
The detector's electronic system processes this signal and determines whether the detected response reaches the configured alarm threshold.
When a potential metallic object is detected, the system can provide an audible and/or visual alarm.
The basic screening process is:
Person enters detector → Electromagnetic field interacts with metal → Sensor detects signal → System processes signal → Alarm is generated
Modern WTMD systems can divide the detection area into multiple zones, helping security personnel identify the approximate vertical location of the detected object.
Walk Through Metal Detector vs Hand Held Metal Detector
Walk-through and handheld metal detectors serve different purposes.
| Feature | Walk Through Metal Detector | Hand Held Metal Detector |
|---|---|---|
| Screening method | Person walks through portal | Operator scans manually |
| Screening speed | High | Lower |
| Continuous entrance screening | Excellent | Limited |
| Alarm localization | Zone-based | Operator identifies location |
| Secondary inspection | Limited | Excellent |
| Portability | Usually fixed | Highly portable |
| Typical use | Primary screening | Secondary screening |
For many security checkpoints, the two technologies work best together.
A person can first pass through a walk-through metal detector. If an alarm occurs, security personnel can use a handheld metal detector for secondary inspection.
How Many Zones Does a Walk Through Metal Detector Need?
There is no single zone count that is suitable for every project.
The correct number of zones depends on the security requirements and application.
6–8 Zone Systems
Suitable for basic personnel screening where detailed alarm localization is not the primary requirement.
24-Zone Systems
A practical option for projects requiring more detailed localization while maintaining a relatively straightforward configuration.
33-Zone Systems
Suitable for security checkpoints requiring more detailed detection-zone information.
45-Zone Systems
Designed for applications requiring more detailed localization and higher-level personnel screening.
60-Zone Systems
Suitable for projects where detailed detection-zone localization is a priority.
The final selection should be based on the complete technical specification rather than zone count alone.
Applications of Walk Through Metal Detectors

Humidity
-
Dust protection
-
Installation requirements
5. Evaluate Sensitivity and Stability
A security metal detector should provide appropriate sensitivity while minimizing unnecessary alarms.
6. Check Software and User Interface
Important functions can include:
-
Sensitivity adjustment
-
Zone indication
-
Alarm settings
-
User controls
-
System diagnostics
-
Remote operation
7. Evaluate Manufacturer Support
For large projects, buyers should consider:
