It is mainly used for the following purposes:  Providing Remote Access Control: Authorized users can make a phone call or send a text message to the device from anywhere in the world where there is a GSM signal, without the need for on - site operation. For example, when you are driving home, you can call in advance to open the gate, eliminating the trouble of getting off the car to open the door manually. It is suitable for various types of doors and gates, such as garage doors, swing gates, sliding gates, and access doors. - Enhancing Security: It identifies the caller's number through caller - ID technology, and only responds to calls or text messages from pre - authorized phone numbers. This can effectively prevent unauthorized access, ensuring that only people with permission can open the door or gate. Some models can also be connected to door sensors, motion sensors, etc. When these sensors are triggered, the device will send a text message alert to the user, helping to protect the safety of the property.  Realizing Flexible User Management: Users can add or delete authorized phone numbers through text message commands, which is convenient for managing access rights. For example, in a residential area, the property management can easily add or remove the access rights of residents or visitors; in a commercial place, the administrator can flexibly manage the access rights of employees and customers. - Enabling Timed Control: It can set the time when the relay is closed, that is, control the opening time of the door or gate. Some models also support setting specific time periods during which authorized numbers can be used to control the door opener. This is very useful for some places with regular access needs, such as the gate of a factory, which can be set to open automatically during the morning and evening rush hours. - Facilitating Integration with Other Systems: In some cases, GSM door openers can be integrated with other security or access control systems, such as alarm systems, intercom systems, etc. to form a more comprehensive security management system, providing users with a more convenient and intelligent access control experience.
