Does the turnstile support alarm linkage function?

The technical architecture supports both protocol openness and multi-sensor fusion.
Two technological pillars support the turnstile's alarm linkage function: a standardized communication protocol and a high-precision sensing network.
1. Using a multimodal sensor matrix to establish a baseline for safety perception
Infrared gratings, pressure-sensing flooring, millimeter wave radar, artificial intelligence cameras, and other sensors are integrated into modern turnstiles to provide a three-dimensional traffic behavior monitoring system:
array of infrared gratings: To track the position and movement trajectory of employees in real time, 12–20 sets of infrared radiation sensors are placed in the gate channel. The technology instantly sounds an anti-tailgating alert when several people enter or pass in the opposite direction at the same time. For instance, the full-height turnstile installed in Shenzhen Wanda Plaza uses an infrared matrix to recognize trailing behavior with an accuracy of 98.7% and a false alarm rate of less than 0.5%.
Floor with pressure sensing: It has high-precision pressure sensors built in, allowing it to identify a person's weight distribution and gait. Test data from a posh mall shows that this technology can reliably detect 99.2% of anomalous traffic patterns (such loitering and fast card swiping) and connect to the monitoring center to send out alerts.
Millimeter wave radar: this technology uses the 77GHz frequency spectrum to monitor vital signs without making physical touch. This device can see through clothing to identify people carrying metal objects and create redundant security with metal detecting doors in high-security settings like prisons and chemical industries.
2. To enable smooth system integration, standardize communication standards.
The turnstile uses industrial protocols like OPC UA, Modbus TCP, BACnet, and others to share data with fire safety, monitoring, access control, and other systems.
Linkage to fire: The gate has an integrated fire input interface that can accept fire alarm signals and automatically carry out three tasks: link ground indication lights to show escape routes, play evacuation instructions by speech modules, and unlock all gates in less than 0.5 seconds. According to data from Beijing SKP tests, the turnstile's integrated fire prevention feature cuts the emergency evacuation time from eight to three minutes.
Linking videos: The gate immediately sends alert information to the monitoring center and pulls surrounding cameras for ongoing tracking when it notices unusual activity (such tailgating or intrusion). Through this function, Shanghai Global Port has recovered more than 500000 yuan worth of missing goods and successfully cracked three gang theft cases.
In order to provide closed-loop management of the complete "authentication passage recording" process, access control integration facilitates linking with multimodal authentication systems such IC cards, facial recognition, palm vein, etc. Guangzhou Tianhe City integrated the dynamic QR code gate with the membership system during the promotional time in order to reduce instances of unlawful intrusion in the activity area and increase member verification efficiency by 31%.
The primary purpose is to shift the paradigm from passive response to active defense.
The turnstile's alarm linkage function creates an intelligent closed loop of "perception decision execution" that encompasses the full cycle of pre-warning, in-process intervention, and post-event traceability.
3.Instantaneous alerts for unusual conduct
An anti-tailgating alert The gate automatically locks and turns 120°/90° for each person entering. The system will instantly sound a voice alert and upload an event record if it detects that the channel has been stuck for longer than the predetermined amount of time (for example, five seconds). With the use of this function, Chengdu Taikoo Li has seen a 67% decrease in instances of illegal entrance in remote routes.
Alarm for reverse intrusion: If staff are seen arriving from the exit direction when the gate is in one-way traffic mode, the system instantly locks the gate and connects to the monitoring camera for tracking. This feature cuts response time to 0.3 seconds and achieves a 100% detection rate for reverse intrusion situations, according to testing conducted at Hangzhou Tower.
Overcoming the alarm: When employees try to scale the fence, the system instantly sounds a loud alert and sends video evidence to the security headquarters thanks to the synchronized monitoring of millimeter wave radar and infrared grating. Illegal crossing incidences have stopped since this function was implemented in a particular chemical plant.
4.Quick reaction to crises
Principle of fire priority: In addition to being connected to the emergency lighting and evacuation indicator system, the gate has a power-off typically open module that automatically opens within 0.5 seconds of receiving a fire alarm signal. According to test results from Shanghai Henglong Plaza, this innovation increases evacuation effectiveness in fire situations by 40%.
Design that is riot-proof: The gate uses an anti-reverse mechanism and a hydraulic shock absorber core. The gate automatically rotates 15 degrees to buffer and lock when an external impact is detected, transferring the impact force data to the management platform in the process. 97% of violent card tampering activities were successfully stopped by the prison-specific full height turnstile that was installed in one Beijing prison.
5.Decision support based on data
Analysis of passenger flow heat: A "digital twin" of mall safety management can be created once the daily traffic data produced by the gate has been cleaned and integrated (including entry time, stopping area, and flow trajectory). For instance, a particular supermarket discovered through the analysis of gate data that there was only a 12% overlap in passenger traffic between the food section on the B2 level and the beauty area on the L1 level. This led to a 67% reduction in blind spot coverage in the surveillance camera layout.
Modeling risk behavior: creating a baseline model for traffic behavior by fusing machine learning techniques with historical data. The system automatically starts the inquiry process when it detects behavior that deviates from the baseline (for example, a worker regularly entering the warehouse area outside of working hours). Through this feature, a particular chain supermarket was able to successfully stop three instances of internal theft, resulting in a 76% reduction in loss amount year over year.
6.Practice Scenarios: Value Shift from Ecological Integration to Single Device
Turnstiles' alarm linking feature has established standardized solutions across a number of industries, and its benefits are visible in three areas: increased efficiency, cost reduction, and experience enhancement.
7.Commercial Complex: Harmonizing Experience and Safety
Management without personnel: The full-height turnstiles installed in Shenzhen Wanda Plaza are able to operate without human assistance around-the-clock. The efficiency of the VIP channel is raised by 40% and personnel costs are decreased by 35% through the use of facial recognition and dynamic QR code verification.
Realization of membership benefits: In addition to restricting certain advantages and downgrading credit ratings for members who regularly break the rules, Hangzhou Tower will integrate gate access records into the membership credit system. The operational order has been improved and the member violation rate has decreased by 67% thanks to this approach.
8.Industrial park: two-pronged assurance of efficiency and safety
Control of dangerous areas: Incorporating gas detectors and anti-static devices, a chemical industry has installed explosion-proof rotational turnstiles at the raw material storage entry. The device reduces the frequency of safety mishaps by 82% by automatically locking the gate and connecting the exhaust system when the concentration of flammable gas surpasses the standard.
Logistics flow optimization: To accomplish personnel and cargo flow management, JD Asia's top warehouse is connected to the AGV scheduling system via turnstiles. This method lowers the equipment failure rate by 40% and increases logistical efficiency by 25%.
9.Public transit: exact management in the face of heavy passenger volume
Subway Hub Application: "One code access" is supported by the turnstiles installed at Shanghai Metro's Xujiahui Station. Using the dynamic QR code produced by the subway app, passengers may concurrently verify their tickets and health codes. This feature lowers the cost of human verification by 60% and improves traffic efficiency by 30% during busy hours.
The implementation of a full-height turnstile with 15° anti-reversal technology at Beijing South Station efficiently prevents terrorists from entering in the opposite direction, demonstrating anti-terrorism and preventative efforts at train stations. During the 2024 Spring Festival travel rush, the device effectively stopped three suspicious item carrying events, protecting the travel of 12 million passengers.
