Detailed Explanation Of Access Control System Types: How To Choose A Smart Access Control Solution Suitable For Your Enterprise?

The access control system has long gone beyond the scope of simply "opening and closing doors". It has become the core part of the modern physical security system, digitalizing and intelligently processing the management of people, space and time. This system not only involves preventing unauthorized entry, but also achieves refined management of personnel flow, traces behavior trajectories, and is interconnected with fire protection, security and other systems to build a proactive safety environment. Whether it is a corporate campus, data center, high-end residence, or medical institution, a properly designed access control system is the cornerstone of safety and efficiency.

What are the main types of access control systems?

In terms of technical principles, access control systems are mainly divided into several categories. The first popular one is the password keypad access control, which is verified by entering a preset password. The cost is relatively low, but the security is at an average level. The password is easy to be leaked or peeped. Card access control is the most frequently used, including IC cards, ID cards, etc., which are identified by swiping the card. Management is more convenient, but there is a risk that the card will be copied or lost.

The current mainstream development direction is biometric access control, which authorizes people by identifying their inherent physiological characteristics. Common ones include fingerprint recognition, face recognition, iris recognition, etc. This type of system is highly secure and does not require additional media. However, the initial investment and maintenance costs are relatively high. In addition, there is also mobile credential access control based on mobile phone NFC or Bluetooth. This access control integrates permissions into personal smartphones and is very convenient to use, representing the future integration trend.

How to choose an access control system suitable for your enterprise

When choosing an access control system, you must start with a comprehensive evaluation based on the actual needs of the enterprise. First of all, the level and area of ​​protection must be clearly defined. Places such as core computer rooms and financial rooms need to ensure the highest security level. Multiple authentication methods may be used, such as card swiping and fingerprint authentication, while public office areas can use a single authentication method. Secondly, the scale of personnel and frequency of turnover must be considered. For large enterprises, a system that can support a large number of users, has high concurrent processing capabilities and is easy to manage in batches is needed.

The key determinants include budget. In addition to the one-time investment in hardware equipment (the so-called hardware equipment includes card readers, controllers, and electric locks), the cost of software licensing, installation and debugging, later maintenance, and upgrades must also be taken into consideration. The scalability of the system is also very important. You should choose a platform that adopts a modular design and can support future additions or integration with other systems (such as video surveillance, visitor management, and attendance systems) to avoid the formation of information islands.

What should you pay attention to when installing an access control system?

The quality of installation of the access control system directly determines the stability and safety, and it must be constructed by a professional team in a standardized manner. Wiring is the foundation. Signal wires and power wires should be laid separately. Wires that comply with specifications should be used and shielded to prevent signal interference from causing false alarms or malfunctions. As the brain of the system, the controller should be installed in a safe, dry, and easy-to-maintain weak current room to avoid moisture and electromagnetic interference.

The details of on-site equipment installation must not be underestimated. Card readers and biometric terminals should be installed in a solid location that is not prone to damage, and their height should meet ergonomic requirements. The choice of electric lock should match the type of door body such as wooden door, glass door, fire door and opening direction to ensure sufficient locking force. After the installation is completed, it is necessary to carry out comprehensive debugging work to test whether the normal opening function of each door, the illegal intrusion alarm function, and the fire-linked glass-breaking function operate normally.

How to link the access control system with the fire protection system

Life first is the number one principle of safety, so the access control system must absolutely comply with fire protection requirements. According to fire regulations, after the fire alarm is confirmed, the access control system must be able to automatically release the electronically controlled locks on all evacuation passages to ensure that personnel can escape unimpeded. This linkage is generally achieved with the help of dry contact signals sent by the fire protection system or through network protocol integration.

In terms of linkage, in addition to turning everything on in an emergency, its level of intelligence can be further improved. For example, the system has the ability to receive location information from fire alarm signals and only release access control to relevant areas or floors to prevent the spread of fire. At the same time, the access control system can feedback the real-time status of each entrance and exit to the fire control center to assist in rescue decision-making. In daily management work, it is also necessary to set up an emergency evacuation button (glass breaker) so that the door can be forced to open through manual operation in the event of a power outage or system failure.

How to troubleshoot common faults in access control systems

When the access control system is in use, various faults may occur, and only by mastering basic troubleshooting methods can it be restored quickly. The most common problem is "I have permission but the door doesn't open." First, check whether the power supply of the electric lock is in a normal state and measure the lock terminal voltage; secondly, check whether the door magnetic signal can be transmitted normally, and check whether the system prohibits opening the door because the door is not closed properly; then, check whether the communication line between the card reader and the controller is unobstructed.

If there is a communication failure, such as some door points being offline, or all of them unable to be managed, then you need to check the network switch and controller power supply. You can try to restart the controller and check the IP address settings. If the card swiping or recognition response is slow, it may be that the card reader antenna is aging or there is interference from metal around it. For biometric devices, you need to check whether the recognition window is clean and whether the user template needs to be re-registered. All maintenance operations are recorded and preventive maintenance is carried out regularly.

What is the development trend of access control systems in the future?

Access control technology is constantly developing in the direction of becoming more intelligent, integrated, and intangible. The deep integration of artificial intelligence is an extremely obvious trend. The system can not only carry out face recognition operations, but also analyze people's behavior patterns, identify abnormal behaviors such as tailing and loitering, and proactively send out early warning signals to achieve a transition from passive control to active security.

There is a trend towards "cloudification" and "mobility". Cloud-based access control management reduces local server deployment and maintenance costs, and can support management at any time and anywhere with the help of web pages or mobile APPs. The mobile voucher will completely replace the physical access control card, achieving senseless access through mobile phone Bluetooth or NFC. In addition, the access control system will be further integrated into the smart building IoT platform, and will be linked with lighting, air conditioning, and elevator dispatching to provide personalized environmental services based on the identity and location of the person, thereby improving the overall management efficiency and experience.
