How to choose an access control system suitable for modern office environments? This article will discuss it from six parts

一.Requirements

Before anything starts, we need our own purpose; what challenges do we face with the access control system? Is it the first time to use it or the existing functions no longer meet our usage environment? Do we only do attendance or attendance and access control together: Do we need to divide the area according to authority? What is the area of ​​our current office space? Do we need to update the subsequent personnel and venue? Does our company need to develop customized functions for our company based on basic functions?

The access control system solution is both a common function and a customized requirement; the common reason is that the conventional functions on the market can basically meet our usage environment, and the customization is because we must first understand our own situation and choose and use the access control system suitable for our own office environment according to our own situation.

二. Hardware

Giải pháp

It can be divided into Android system and Linux system; the difference between the two is simply that the Android system is easy to develop secondary and can inherit and be compatible with other APKs I want; Linux system development requires professional programmers to do it, so if your company only uses the attendance access control function by itself and does not want to invest too much time in development, then the Android system access control system is the most suitable; on the contrary, if your team is doing software systems and all engineers have them, then you can choose Android and Linux systems;

System:

From Android 7 to Android 11, this interval is a usable interval. Although our mobile phone solution can reach Android 12 or Android 13, there is still a slight difference in technology between electronic consumer products and industrial products.

But Android 11 is enough for us to use.

Recognition mode:

Facial recognition:

Facial recognition is a technology based on biometric recognition that analyzes and matches the uniqueness of the face for identity authentication or authorization. Then its advantages and disadvantages are also obvious. There is no need to carry keys or access cards. Users only need to show their faces in front of the camera to pass quickly. Facial recognition is an identity authentication method based on biometrics, which has high security. The uniqueness of the face makes it difficult to forge and impersonate.

The contactless recognition method used by facial recognition improves health and safety and reduces physical contact.
Disadvantages: Facial recognition involves the collection and storage of personal biometrics. In low light or extreme angles, the accuracy of facial recognition may be affected.

Nhận dạng vân tay:

Fingerprint recognition is also a technology based on biometric recognition, which collects and matches personal fingerprints for identity authentication.

Advantages: Everyone’s fingerprint is unique, even twins will not have the same fingerprint, so fingerprint recognition has high accuracy;
Convenience: Users only need to place their fingers on the fingerprint scanner to pass quickly, without carrying anything. Due to the complexity and uniqueness of fingerprints, it is difficult to forge fingerprints, and the security is high

Convenient storage: The storage and management of fingerprint data is relatively simple, and the storage space required is small, which can be easily used in the background management of the access control system

Nhược điểm:

Fingerprint wear: The fingerprints of some users may be worn due to work and age factors, resulting in fingerprint recognition failure or reduced accuracy.

Hygiene issues: Fingerprint recognition requires direct contact with the sensor, which may cause health hazards.
Environmental impact: Fingerprint recognition has certain requirements for the environment. For example, when there is water, error or other contaminants on the user’s finger, it may cause recognition failure

Nhận dạng mống mắt:

Iris recognition in the access control system is a biometric-based identity authentication technology that confirms identity by analyzing and identifying the unique pattern of an individual’s iris. The iris is a ring-shaped structure in the colored part of the eye. Everyone’s iris pattern is unique, so iris recognition is considered to be a very safe and accurate way of identity authentication.

High security: The iris is a very unique and difficult-to-forge biometric feature, providing extremely high security
Non-contact: Iris recognition is usually performed in a non-contact manner, without direct contact with the device;
Disadvantages: The cost of the iris is still relatively expensive among many biometric features, and user acceptance is not yet widespread

Palmprint recognition:

Palmprint recognition is a biometric technology that scans and analyzes the leader’s pattern characteristics to authenticate identity. In addition to palmprint recognition, there is also palm vein recognition, which is more accurate than palmprint recognition
High accuracy: Palmprints contain a wealth of feature points, which are unique.
When using palmprint recognition, you also need

NFC recognition:

NFC recognition is not a type of biometric recognition, but it is increasingly used in access control systems.
Convenience: In addition to traditional NFC card recognition, many smartphones are now compatible with NFC. Users only need to bring the device close to the access control reader to complete identity verification, which is simple to operate.

QR code recognition:

QR code recognition is the same as NFC recognition. Although it is not a type of biometric recognition, it is often used in conjunction with biometric features;

Users only need to generate or receive a QR code through a smartphone, and then scan it on the scanning device of the access control system. The operation is still simple and fast;

However, when using QR code recognition, the validity period of the QR code must be set to prevent the QR code from being copied and abused, thereby improving security;

Temperature detection:

The temperature detection function is an optional function of the access control system. You can determine whether it is needed based on your needs. Temperature detection. Especially in places with rigid health requirements, it is necessary to ensure that every employee who enters the authorized range is in a healthy physical environment. Generally, an infrared temperature detection device is added to the access control system.

Alcohol identification:

Alcohol identification in access control systems is an emerging security measure that requires alcohol testing of people entering specific areas to improve security and management levels;

When excessive alcohol concentration is detected, the system can automatically trigger an alarm, prevent people from entering and notify management personnel to take further measures

三.Software

The conventional access control system should include attendance, access control, and working hours calculation. There will be many small points to be included in each part. Let’s briefly talk about the example. Attendance. Do we need to set single attendance or multiple attendance. Reject video attendance, etc.

Budget example

Assuming a small to medium-sized office needs to install an access control system to cover 4 doors, the budget example is as follows:
Equipment cost
4 card readers ($150 each): $600
1 controller (supports 4 doors, $500): $500
4 electromagnetic locks ($200 each): $800
50 cards ($2 each): $100
Software cost
Access control management software (one-time fee of $500): $500
