Intelligent Development from Traditional to Networked Alarm Industry

In traditional security, video surveillance and alarm are the two main security forces. Under the background of “building a harmonious society” and “smart city”, video surveillance has been greatly developed, and the alarm service industry seems to be “quiet”, but as the foundation of urban security, the alarm service industry is also quietly taking place. Changes will eventually form a social alarm service industry with a good human environment, policy environment, investment environment, and market environment.

From traditional alarms to networked traditional alarms with "defense" as the main method, based on wired telephone network alarming methods, the front end is the telephone line alarm host, and the back end uses the telephone to answer the host. The alarm signal is transmitted from the front end to the back end by CID and other protocols. Today, this model can no longer fully meet the needs of the “pan-networking” era. The networked alarm system operates in its own monitoring room and builds a management platform. It installs alarms for businesses that need to install anti-theft alarm systems, and distributes these alarms. The alarm generated by the device is transmitted to the management platform through various transmission methods, and the monitoring room is unified to handle the alarm situation. The operator operating system handles the alarm situation immediately so that the major commercial shops are protected from losses.

At present, a disruptive and innovative change is sweeping the security industry. The security industry is merging with other industries at the fastest pace. The same applies to the networked alarm industry. Practitioners must integrate high-quality resources and new technologies, define the markets they face with the idea of ​​a "pan-network," and reconstruct low-value business segments. This is the requirement of the times.

With the arrival of intelligence as the fifth wave of information, the accelerated convergence of the Internet, the mobile Internet, and the Internet of Things, the rapid adoption of cloud video computing, big data analysis, and intelligent hardware have enabled the Pan-Internet model to land.

In the age of networked alarms and the shifting of networked alarms to visualisation, the alarming industry has continued to innovate, and visual alarms combined with video surveillance have become a new model. By adding an alarm device to the video surveillance in the densely populated areas and regions, the crowd can press the button to realize the alarm. This can be directly followed by the police and the police. The police can also access this video to understand the video intuitively. Alarm condition.

Compared with traditional networked alarm methods, visual networked alarms have the following advantages:

First, it is conducive to taking evidence. The linkage between video and alarm solves the shortcomings of the traditional networked alarm system. The video network alarm system accurately judges whether it is a true alarm or a false alarm through video, thus avoiding the waste of human and material resources caused by blind police. The video network alarm can intuitively understand the front alarm scene through the video image and immediately determine whether the alarm condition is true. At the same time, the system can perform full video and video playback retrieval of the alarm image. The realization of simultaneous transmission of images and alarms facilitates the management of staff, reduces unnecessary troubles, and saves manpower and material resources.

Second, a unified management and control platform for visual alarm networking was formed. The integrated application of video network alarms makes reasonable and effective use of front-end alarm resources and alarm detector equipment, realizes resource sharing, gives full play to the unified management and control of the platform, and makes full use of limited resources while improving the efficiency of resource use. Comprehensively improve the technical level of security. Aiming at the disadvantages of the traditional alarm system, a video network alarm system based on the linkage between alarm and video surveillance has emerged. The front end of the video networking alarm system is mainly composed of alarm equipment and video monitoring equipment. The central part of the system is mainly composed of a platform server and a monitoring client. Video-networking alarm systems are more powerful in functionality, such as providing real-time video viewing services to prevent false alarms.

Thirdly, there are alarm linkage functions, such as motion detection alarms, abnormal offline alarms for devices, linked snapshots, and linked videos, etc.; support for mobile phone services, users can browse videos through mobile phones, receive SMS alarm messages, and so on; , When the alarm event occurs, it can accurately determine the corresponding alarm location; With a large amount of storage capacity, can effectively store 3-5 years of alarm data, convenient and accessible; In addition, the original alarm system seamlessly docking the new system platform without modification You can access the new system.

At present, video surveillance systems and networked alarms have a total of three combinations: one is that both are still independent systems, trigger monitoring systems through alarm signals, and then use the network to transmit to the center platform to achieve linkage; the second is to directly alarm at the front end. The installation of surveillance cameras; the third is to integrate video surveillance on the back-end platform, unified management through the back-end monitoring platform.

Intelligent analysis technology facilitates visualized alarm upgrades The visually-networked alarm system performs a variety of detections through a variety of powerful front-end detectors or surveillance cameras. In recent years, with the development of science and technology, the functions of various front-end detection devices have become more and more complete, surveillance cameras have become more and more clear, and their functions have become more powerful. The intelligent video analysis technology of front-end detection devices has also begun to be applied in alarm systems. .

Intelligent video analysis technology originates from computer vision technology. It can establish a mapping relationship between images and image descriptions, so that the computer can understand the content of video images through digital image processing and analysis.

The front end of the intelligent video alarm system is mainly composed of an alarm device and a video monitoring device. The center of the system is mainly composed of a platform server and a monitoring client. Intelligent video alarm system is more powerful in function, providing real-time video viewing service to prevent false alarms; equipped with alarm linkage function, such as motion detection alarm, abnormal device dropped alarm, linkage capture, linkage video, etc.; support for mobile phone services, users The mobile phone can browse videos and receive SMS alarms. Through the monitoring client, when the alarm event occurs, the corresponding alarm position can be accurately determined. With massive storage capacity, it can effectively store 3-5 years of alarm data, which can be easily checked. In addition, the original alarm system seamlessly interfaces with the new system platform and can be accessed without modification.

The alarm system is continuously improving, from traditional to large-scale networking, combined with video surveillance, to intelligent development, the alarm system functions more and more powerful, and the security industry continues to develop.
