I、 Preface
Many people do not know how to choose between QR code access control integrated machine and split type access control when choosing access control, and are not clear about the difference between these two methods.II、 Noun Explanation
1.split-type access control
Composition: access control controller+reader.Working mode: The reader is responsible for reading card or biometric data and transmitting the data to the controller through methods such as Wiegand, RS485, RS232, etc. The controller performs logic such as permission judgment, door opening, and communication with the backend.
2.QR code access control all-in-one machine
Composition: The controller and QR code reader are integrated into one device.
Working mode: All functions such as data reading, permission judgment, door opening, and communication with the backend are independently completed on this device.
As a professional manufacturer that produces both QR code access control all-in-one machines, controllers, and QR code access control readers, this article will objectively analyze the advantages and disadvantages of both.
III、 Comparison of advantages and disadvantages
1.Split type access control: high security
Advantage:①High security: The controller is usually installed in indoor safe areas (such as ceilings or computer rooms), while the reading head is installed outside the door. Even if criminals damage or dismantle the door reading head, it is impossible to illegally open the door through short circuits or other means, so the safety is relatively high.
② Less network IP required: When using multi door controllers (such as dual door or four door), only one set of power supply and one network cable need to be set up for the controller, reducing the overall wiring quantity.
③Simple AB door interlock logic: Implementing complex AB door interlock functions on multiple door controllers is more direct, with configuration completed within the controller without relying on backend servers or communication between multiple controllers.
Potential drawbacks:
① Increased construction workload: The connection between the controller and the reading head (usually at least four wires: two power supplies and two communication cables) increases the workload of construction and installation.
② Connection stability challenge: With one more connection, there is one more potential point of failure. The more connections between the controller and the card reader, the higher the requirements for daily maintenance and stability.
③ Single point of failure has a large impact range: If multiple controllers are used, once the controller fails, the operation of multiple access controls will be affected simultaneously.
2.QR Code Access Control: Pros and Cons Analysis
The QR code access control all-in-one machine integrates the QR code reader and controller into one device, and all functions (data reading, permission judgment, door opening, communication, etc.) are independently completed on one device.Advantage:
① Simple installation and deployment: As there is no connection between the controller and the read head, at least four wires can be omitted during construction, which improves construction efficiency and shortens the project cycle.
② Intuitive status display: Many QR code access control all-in-one machines come with built-in display screens, which, due to their integration, can conveniently display device status, time, card number, network status, and other information in real time, providing a more user-friendly experience.
③ High independence: One device controls one door, with stronger independence. The access control systems will not interfere with each other and have good system isolation.
Potential drawbacks:
Increased demand for network resources: Each QR code access control all-in-one machine needs to independently connect to the network and occupy an IP address, requiring more network IP addresses than a split system with multiple controllers.
IV. Is the QR code access control integrated machine safe
Many users are concerned about the security of the QR code access control all-in-one machine - can criminals forcefully dismantle the machine and then short-circuit the circuit to illegally open the door?This concern has been effectively addressed with modern access control technology:
① Environmental deterrence: In today's densely monitored office and public places, violent dismantling of QR code access control all-in-one machines will be monitored and recorded, which greatly serves as a deterrent. In addition, most QR code access control all-in-one machines are mostly used indoors and are often manned.
② Security upgrade plan: For scenarios with high security requirements, Cerberus has launched the AC037 security module.
*This module is connected to the QR code access control all-in-one machine through RS485 private protocol.
*The safety module is placed indoors (such as on the ceiling) and is responsible for door opening control.
*Even if criminals dismantle the QR code access control machine outside the door, they cannot open the door lock through short circuiting, which improves the security of the QR code access control machine.
