Network alarm is to use PSTN, TCP/IP, wireless network (GSM, GPRS, 3G, 4G, 5G) and other communication methods in combination with modern electronic intrusion alarm equipment to provide users with economical and convenient intrusion alarm services connected to the network alarm receiving centre (manned 24 hours).

The network alarm receiving centre is the core of the network alarm system. It is the information processing centre of the network alarm system, as well as the decision-making centre for analyzing and processing alarm information, and is responsible for specific implementation. It combines human prevention, technical prevention, and physical prevention to monitor the security system in real time. In case of abnormal situations, after approving the alarm situation, security forces are deployed and dispatched to handle or rescue, ensuring the safety of users’ lives and property.

With the significant improvement of people’s living standards, the mobility of the social population has greatly increased, and the social structure and security have become increasingly complex. Therefore, people are paying more and more attention to the safety of family life and property. The rapid advancement of science and technology, the widespread use of computer technology worldwide, and the rapid rise in people’s call for a better life have highlighted the important role of security and market demand. Simply selling security products and providing after-sales service cannot fully meet the needs of all customers. Various types of professional security service companies have emerged. The network alarm receiving centre is the most important security information processing and decision-making organization for various security service companies or security management departments.

1 Responsibilities of the network alarm receiving centre

The responsibility of the network alarm receiving centre is to provide security services.

2 System construction of the network alarm receiving centre

The main purpose of establishing a network alarm receiving centre is to protect the personal and property safety of users. The main alarm methods are: user (alarm) – network alarm receiving centre (self disposal) – police (network alarm receiving centre cannot handle and report to police for disposal).

The composition of the network alarm system is to install detectors in important places such as commercial stores, residential households, and financial rooms of enterprises and institutions to detect illegal intrusion behavior, fires, or other emergency rescue events. Then, the intrusion alarm system automatically issues an alarm on site and automatically transmits the alarm to the network alarm receiving centre.

The network alarm system does not require manual intervention to alarm, which is fundamentally different from our common voice alarms. It is also different from technical prevention measures that require manual intervention such as closed-circuit television monitoring (CCTV), anti-theft doors, and intercom doorbells. It is a completely automatic and pure technical prevention method.

3 Workflow of the network alarm receiving centre

Usually, a complete regional network alarm system consists of three main parts: user end alarm, network alarm receiving centre reception, deploying and dispatching security force.

(1) User end alarm

The user end refers to the installation of alarm system and alarm detectors with different functions within the customer’s prevention area, such as door contacts, PIR motion sensors, smoke and temperature detectors, glass detectors, etc. When there is illegal intrusion in the prevention area, the detector sends an alarm signal, and the alarm control panel automatically emits an alarm. Once an emergency occurs, an alarm can be triggered through the installed panic button, and the alarm signal can be automatically transmitted to the network alarm receiving centre of the security service company within 2 seconds through various interface platforms.

(2) Network alarm receiving centre reception

After receiving the alarm signal, the network alarm receiving centre immediately displays the accurate location of the alarm customer (accurate to the specific point on the user’s location plan), as well as relevant information such as the name, address, contact person, contact information, and alarm type of the alarm unit on the electronic map. At the same time, the alarm sound will also be activated to prompt. If a monitoring and monitoring review system is installed, it can not only monitor the on-site situation, but also visually judge the nature of the alarm situation from the on-site monitoring images for review.

(3) Deploying and dispatching security force

The network alarm receiving centre confirms the actual report through multiple means and needs to issue an alarm. At the same time, it will quickly report to the command centre of the processing department, and the electronic map can display the trajectory of the vehicle. Dynamically display alarm information. After the alarm is completed, the handling personnel will report the results to the network alarm receiving centre. The network alarm receiving centre will fill out the alarm report and report it to the competent department, and file it at the same time.
