#smarthomealivehome | What is the difference between door sensor and access control？

The door sensor is one of the components of access control. The door sensor is a small sensor used to detect whether the door is closed. There are many electric locks with a door sensor function; the security of the access control system is not only the security of the identification method, but also Including the security of the control system, the security of the software system, the security of the communication system, and the security of the power supply system, the whole system is a whole with good practicability.

In life, the door magnetic system can generally be divided into three parts: door magnetic switch, door magnetic sensor (detector), and door magnetic alarm. Some access control systems are based on the smart bus and the same system platform, so that the smart terminal of the smart home can easily access the door phone of the video doorbell system and the management center, and realize the functions of intercom, message, photo and access control of visitors, which has become our family security first line of defense. What is the difference between door magnetism and access control?

What is door sensor ？

The door sensor is used to detect whether doors, windows, drawers, etc. are illegally opened or moved. The magnetic door system consists of two parts: a wireless transmitter and a magnetic block. The door sensor is composed of two parts: the wireless transmitter module and the magnetic block. There is a "reed tube" component at the two arrows of the wireless transmitter module. When the distance between the magnet and the steel reed tube is kept within 1.5 cm, The steel reed tube is in the disconnected state, once the distance between the magnet and the steel reed tube exceeds 1.5 cm, the steel reed tube will close, causing a short circuit, and the alarm indicator light will be on and an alarm signal will be sent to the host at the same time.

What is access control ？

Magnetic door is one of the components of access control. Access control is what we often call the access control system. Including controller, card reader, electric lock, power supply, exit button, door sensor, etc. Access control refers to the prohibition authority of the "door", which is the guard against the "door". The "door" here, in a broad sense, includes all kinds of passages that can pass, including doors for people and vehicles. Therefore, access control includes vehicle access control. In the application of parking lot management, vehicle access control is an important means of vehicle management.

The difference between door magnetism and access control

1. Door sensor is one of the components of access control.

2. The door magnet is a small sensor used to detect whether the door is closed. There are many electric locks with a door magnet function. The security of the access control system is not only the security of the identification method, but also the security of the control system, the software system, the communication system, and the power system. The whole system is a whole. For example, in some fingerprint access control systems, its controller and fingerprint reader are integrated, and it must be installed outdoors during installation, so that the wires that control the lock switch are exposed outdoors and are easy to be opened by people.

3. Once the distance between the magnet and the steel reed tube exceeds 1.5 cm, the door sensor will close, causing a short circuit, and the alarm indicator will light up and send an alarm signal to the host. Access control can effectively prevent outside salesmen from entering the company to disturb the office order, and its practicability is relatively good.
