One of the key factors for a company that employs many workers is access control and management of critical facilities, spaces, and factories. In reality, many companies often do not have an effective access control system. Companies that recognize the importance of access control often use IC card control systems. However, methods using IC cards have several weaknesses.
First of all, it is the case of lending IC cards to other workers or colleagues. This situation is common, but it also has a problem that it is difficult to control properly at the corporate level. Another problem is the loss of the card. People wear it like a necklace to prevent loss, but they often lose it. If the employee who lost the card notifies the company immediately and takes action, the problem can be prevented. However, it can lead to a serious problem if they don’t know or find out about the card loss later. This is because the person who gets the card can use it maliciously. And in the case of IC cards, we can consider a bad situation in which someone is intentionally approaching and stealing for a specific purpose. In this case, you are exposed to even greater risk.
Biometric technology-based access control
Due to these disadvantages, more and more companies are using biometric-based access control and management systems using biometric information of workers. The most commonly used biometric method is the fingerprint recognition system. This method stores human fingerprints in the database in advance and controls access by comparing fingerprint information whenever workers enter and exit. This method is effective in solving problems with IC cards.
However, there are several issues when applying this method to industrial sites. In the general office environment, there is no problem with access because workers do not wear protective equipment such as gloves. However, workers who enter the space where protective gear is required to wear it will have to take off the protective gear, verify their fingerprints, and wear it again, causing inconvenience and time delay. If the number of workers entering and leaving is high, this area becomes a bottleneck, which in turn can lead to reduced work productivity. Even without wearing protective equipment, fingerprint recognition is often not possible depending on the worker’s characteristics (such as fingerprints fading due to a lot of bare-handed work) or the worker’s health condition.
For this reason, access control systems using various human information are being introduced. There are methods using human iris, speech recognition, hands or veins, or handwritten signatures. However, these methods also need to address the issues mentioned above to apply to industrial sites where various variables and risks exist.
Considering this and that, the most effective biometric-based access control and management is facial recognition technology. The overall configuration and method are similar to the fingerprint recognition system. It is a method of storing database of face image information of workers who need access to spaces or facilities that need access, and then comparing face image information to manage access whenever workers enter and exit. Facial images can also be divided into 2D and 3D methods depending on the nature of the work or importance of the facilities entering and leaving the building. As you may have noticed, face recognition-based access control systems are less vulnerable and more efficient than IC card and fingerprint recognition systems. First of all, there is no possibility of lending or losing it like an IC card. And the current practical face recognition system accurately recognizes the worker’s face even when he or she is wearing a helmet or glasses, so there is no inconvenience in having to take off and put on the protective gear that the fingerprint recognition system has.
Another consideration in introducing the access control system of biometric technology is the area of utilization. Fingerprint recognition, iris recognition, etc. are suitable for access control, but it is difficult to expect more than that. This is because you can manage the working hours based on the time information at the time of entry, but you cannot understand the actual work status or contents. On the other hand, AI CCTV solutions with facial recognition technology can be integrated from access control to monitoring work status, determining access to dangerous areas. Therefore, you can perform various tasks with one system. This also has the positive side effect of significantly reducing system adoption costs, maintenance costs, and work burdens.
The third advantage of AI CCTV solution using face recognition technology, following suitability of industrial field application and scalability of coverage, is the ability to handle events. Because most IC cards and fingerprint recognition systems are designed with a single system model, event processing is weak. For example, if the IC card and fingerprint information are incorrect and cannot be authenticated, most likely the account is disabled for a period of time after several attempts or reset through the administrator. Therefore, it is difficult to detect or respond effectively to an attempt to enter with a malicious purpose. But, AI CCTV solutions with face recognition include notification and processing functions that help control centers or administrators to take immediately necessary actions.
Based on what has been explained so far, AI CCTV solution is the most effective way to control and manage access to important facilities, facilities, and spaces. And also AI CCTV can ensure the efficiency of access control operations, the applicability of various operations, event management processes, and the scalability and operability of AI technology applications. To sum this up, it’s the solution that guarantees the highest ROI.
