Notes on the installation of the access control controller in the access control system

The controller should not be installed next to the high-voltage power supply box, as well as as a large transformer or high voltage , strong current field, high temperature, humidity, strong magnetic field, environment with corrosive gas.

When installing the access control system, pay attention to the choice of position to prevent electromagnetic interference. The card reader should not be installed on metal objects, and the distance between the two card readers should not be less than 30 cm. The connection between the network adapter and the controller is hand in hand.

In order to ensure the safety of residents to the greatest extent, visual intercom access control is available. When strangers want to enter the building, they can be blocked through visual intercom access control, so that the family can live in a safe living environment.

How to use the RFID access control card?

Application process of access control card Preparation materials When applying for access control card, you need to prepare your personal ID card. If you are the owner of the community, thenYou don't need to provide a property certificate or a house purchase contract. If you are a tenant in this community, you only need to provide a rental contract.

Use RFID card reader: Buy an external RFID card reader, put the access control card on the card reader, and then use the corresponding software to read the card information to the mobile phone. Next, connect your mobile phone to the access control system and try to use the access control card information in the mobile phone to turn on the access control.

Use the NFC function of the mobile phone. First, open and log in to Alipay on the mobile phone, enter "Apply" in the search bar at the top of the page and enter the life account, then click "My Apply Code" at the bottom of the page, and finally click "Add Apply Code" and complete the authorization to get your own access control card. Use the physical access control card.

Electronic access control principle and introduction

1. Access control controller is a digital management system for managers to enter and exit. Common access control systems include: password access control system, non-contact IC card (inductive IC card) access control system, fingerprint iris palm biometric access control system, etc.

2. Magnetic lock principle We know that each magnet has two poles, one north pole (N pole) and one south pole (S pole). Magnets have the characteristics of same-sex repulsion and opposite sex attraction. Electromagnetic locks take advantage of the characteristics of magnets. Locks made of permanent magnets (magnetic beads) are also called "electronic locks".

3. The principle is that the controller accepts the personnel information and the corresponding authorization information sent from the management computer, and transmits the swipe record of entering and exit to the computer at the same time. A single controller can form a simple access control system to manage one or two doors.

4. Introduction to the principle of access control system To understand the principle of access control system, you must first know the hardware composition of the access control system. Access control system hardware includes: multi-function scanner, host, controller, motor, transmission device, sensor, each of which has its own important role.

5. The access control system is an indispensable part of the intelligent building security automation system, and it is also one of the necessary systems for all intelligent buildings. According to the latest intelligent building design standards, access control system, anti-theft alarm system, closed-circuit television monitoring system and electronic patrol system together constitute the main part of the intelligent building security system.

6. First of all, let's talk about the similarities between the principle of IC card and fingerprint unlocking: compare the read identity information with the information in the system (previously registered). If it is the same, it means that the identity is correct, and the corresponding actions are performed, such as opening the door lock. Differences: 1. IC card.
