Large-scale factory security video surveillance solution analysis

A large-scale industrial and mining enterprise covers an area of ​​more than 5 million square meters, with a wide distribution of monitoring points and a large quantity, and it is constructed in batches and successively. As these monitoring systems are constructed in different periods and in different departments, monitoring screens and video data are created. Decentralization and poor use of the problem arise.

To establish a high-quality and efficient production management system, form a good production system, effectively protect the legal rights and personal safety of the company’s employees, promote the development of the company’s business, protect the company’s assets, and further enhance the enterprise’s video surveillance system in combination with “human defense” and “technical defense”. To promote crime prevention, improve public security, and improve management efficiency, and better serve corporate benefits.

Status and requirements

A factory video surveillance network is mainly used for security precautions in all important positions in the plant. It can be divided into four parts: front-end camera guns, front-end video processing equipment, transmission equipment, and terminal equipment. The overall architecture topology is as follows:



Situation Analysis

(1) The video storage method has a high degree of risk. At present, all video surveillance videos are distributed and stored on more than a dozen home PCs. The storage medium provided is a desktop application-level hard disk, and faces 7X24 hours of continuous storage strength. It is often not competent; and all video data is stored on a single hard disk. Once the hard disk is damaged or the operating system fails, all video data will be difficult to recover.

(2) Insufficient storage space for videos. For enterprises, the long-term preservation of video evidence is a strong testimony to ensure that the incidents occurred after the accident. The basic requirements for the general surveillance area reach more than 30 days, and even for the important monitoring areas, more than half a year's worth of video recording is required. Data or permanent backup. Due to the use of ordinary PC local storage, the space that can be stored is limited, resulting in the storage time is far from being achieved, and even to achieve the purpose of prolonging the video storage time, the use of reduced video resolution to store video, so that the video effect greatly reduced.

(3) The video surveillance management is decentralized, and a unified monitoring center system has not been formed, so that the company's security monitoring network cannot form an overall network, resulting in multiple problems such as troubles in monitoring and management, untimely scheduling, and video storage dispersion.
