What are the functions of turnstiles in improving the security system of shopping malls?

一,Upgrade the physical barrier from passive interception to active defence.
1. Understand how to run the full-height structure without people
The full height rotating gate has a 360° enclosed design and is normally 2.2 meters tall, making it a physical barrier that keeps people apart. Its main benefit is that it can run without anyone being there 24 hours a day, 7 days a week. It does this by using a combination of mechanical locking and intelligent unlocking to make sure that the channel is entirely blocked when someone tries to get in without permission. For instance, the full-height turnstile at Shenzhen Wanda Plaza automatically goes into "fully enclosed mode" after closing at night. It also has an intelligent alarm system that cuts down on illegal intrusions by 82% year-on-year and cuts down on the number of security personnel who have to patrol at night, lowering labour costs by 35%.
2. Using anti-tailgating technology to build dynamic protection
Multi-sensor fusion lets rotary turnstiles stop people from tailgating:
Infrared grating matrix: There are 12 sets of infrared radiation sensors in the gate channel that keep an eye on the people who are passing through in real time. If more than one person is detected entering or leaving, the system immediately sets off an alarm and locks the gate.
Floor that senses pressure: It can tell where people are standing by using high-precision pressure sensors. According to test data from a high-end shopping mall, this system can correctly identify 98.7% of tailgating behaviours and has a false alert rate of less than 0.5%.
AI behaviour analysis: use the camera and edge computing module together to look at how fast and how people walk in real time. The system immediately connects to the monitoring centre and sends out warning information when it sees strange behaviour, including quickly flushing cards, roaming around, or spying.
3. Make it easier to adapt to different environments and include more security measures.
The turnstile is designed with an IP65 protection rating to handle the harsh conditions of shopping malls. It can handle dust and precipitation damage and work in temperatures as low as -25 °C and as high as 70 °C. For instance, a revolving gate machine set up in a shopping mall on Central Street in Harbin during the winter employs a heating module to keep the gate from freezing, which keeps the equipment running smoothly even when the temperature drops to -30 °C and the failure rate is less than 0.1%. The device also has an emergency power interface that can switch to backup battery power source automatically if the power goes out. This keeps the fundamental functions running and helps with emergency evacuation.
二,Integrating smart technology: going from single control to making decisions based on data
1. Multimodal recognition makes verification more accurate
The turnstile uses several ways to verify identity, such as facial recognition, palm vein detection, NFC (near-field communication), and more. This creates a "biometric+physical credentials" two factor authentication system.
Facial recognition: The accuracy of recognition is 99.99% with 3D structured light technology, and the response time is cut down to 0.3 seconds. Shanghai Henglong Plaza has installed facial recognition gates so that VIP customers can "swipe their face and get card free" to get through quickly. This has improved the efficiency of the VIP channel by 40% and the customer satisfaction index by 22%.
Palm vein recognition: This method uses near-infrared light to take pictures of palm veins. It can tell if someone is alive and is hard to fake. A test done by a certain chain supermarket found that the false recognition rate of the palm vein recognition gate is just 0.0001%. This is two orders of magnitude higher than traditional fingerprint recognition.
Dynamic QR code verification: connected to the mall's membership and spending systems, it makes QR codes that only work for a short time (like 15 minutes) to stop people from using the same voucher more than once. Guangzhou Tianhe City deployed dynamic QR code gates during the promotional period to stop people from breaking into the activity area and speed up the process of verifying members by 31%.
2. The data centre makes decisions about security
You may make a "digital twin" of mall safety management by cleaning up and combining the daily traffic data from the turnstile, which includes things like entry time, stopping area, and flow trajectory.
Heat map of passenger flow: By looking into gate data, we can find high-risk regions (such distant tunnels and nocturnal commercial areas) to help us decide how to best use security resources. Chengdu Taikoo Li found that just 12% of the people who went to the B2 level eating area also went to the L1 level beauty area. As a result, the placement of the surveillance cameras was changed so that there were 67% fewer blind spots.
Warning of strange behaviour: Use historical data and machine learning methods to create a baseline model for how traffic behaves. The system automatically starts an investigation when it sees behaviour that is different from the baseline, such an employee going into the warehouse area a lot outside of work hours. This feature helped a certain shopping complex stop three internal thefts, and the amount of losses went down by 76% from the previous year.
Improving the emergency plan: In very bad situations like fires and terrorist attacks, gate data can provide you the right numbers to use in an evacuation simulation. By simulating gate traffic data, Beijing SKP improved the design of evacuation pathways so that emergency evacuation time went from 8 minutes to 3 minutes, in line with the "Fire Safety Management Rules for Large Commercial Complex."
三,Expanding scenario links: from separate devices to an integrated ecosystem
1. Deep integration with the fire protection system
The turnstile has a fire connection interface that can get fire alarm signals and do the following things automatically:
Gate unlocking: After getting a fire alarm signal, unlock all gates within 0.5 seconds to make sure that evacuation routes are clear.
Voice directions: Use the built-in speaker to play evacuation instructions and connect with ground indication lights to show the way out.
Status feedback: The fire control centre gets real-time updates on the status of the gate unlocking, which helps with command decision-making.
Test data from Shanghai Global Port shows that the turnstile's built-in fire protection feature makes evacuations 40% faster and lowers the chance of injury to people by 65%.
2. Set up a closed loop with video cameras
The connection between the turnstile and the mall's video surveillance system makes it possible to fully handle the process of "event triggering automatic tracking evidence fixation":
Event trigger: When the gate sees something strange happening, like someone tailgating or breaking in, it automatically sends an alarm to the monitoring centre and marks the spot where the event happened.
Automatic tracking: The monitoring system uses neighbouring cameras to keep an eye on the people involved and record their behaviour over time.
Proof that is set in stone: Link and save records of people who use the gate with surveillance videos to make a full chain of proof. This function helped a certain shopping mall investigate a gang theft case and get back merchandise worth more than 500,000 yuan.
3. Very closely linked to the membership system
The turnstile is now a physical way to get membership advantages, and when it's connected to the membership system, it can do the following:
Marketing with precision: Automatically give access rights based on membership levels (for example, black gold members can queue for free and gold card members can only use certain channels). Also, show personalised discount information on the gate display screen. Testing at Hangzhou Tower showed that this feature makes high-net-worth clients remain 40% longer and boosts the amount of cross-floor shopping by 35%.
Managing credit: Add records of who enters and leaves the property to the member credit system. Give members who break the rules often (such tailgating or trespassing) a lower credit rating and take away some of their rights. This method has helped a certain chain supermarket cut its member violation rate by 67% and greatly enhance the order of its operations.
