1、 Overview: The high-definition network video monitoring system is a fully digital video monitoring system that has emerged in recent years. It replaces traditional cameras with digital high-definition network cameras, directly outputs digital high-definition signals, and can be transmitted to any location extended by the network through various networks such as local area networks, wide area networks, and wireless networks. It can also be centrally managed through a management platform. In terms of wiring, it eliminates a large number of video cables and finally integrates multiple signals into a fiber optic cable to enter the monitoring center, greatly simplifying the construction difficulty. The system not only has high clarity, but also is powerful and easy to expand, which will bring users a better experience.
2、 System design
The front-end of the system is composed of various high-definition network cameras, which are connected to the switch through a network connection, and finally integrated into a network cable to enter the monitoring center.
One or more storage servers, digital matrix, and monitoring workstations must be equipped in the monitoring center, which are also connected to the switch through Ethernet cables.
The storage server is a device specifically responsible for recording and storing images transmitted by cameras.
A digital matrix is a device specifically designed to drive TV walls, capable of driving multiple large screens.
The monitoring workstation is used to control the digital matrix, retrieve and replay recorded data from the storage server.
Client computer, not a mandatory configuration, refers to the computer of other users outside the monitoring center.
Router is not a mandatory configuration. To achieve remote monitoring of external networks, a router is required.
OLT is a local equipment specifically responsible for fiber optic links, matched with ONU for the transmission of monitoring video, network and other data streams.
ONU is a terminal device specifically responsible for fiber optic links, matched with OLT for the transmission of monitoring video, network and other data streams.
The 10 Gigabit Core Switch is a core device specifically responsible for forwarding large network traffic, used for centralized forwarding and management of all video streaming network data. 3、 Function introduction: 1. Monitoring center function - monitoring, recording, and playback in the monitoring center,
The storage server can accommodate multiple hard drives and is specifically responsible for video storage work.
The digital matrix has multiple display output ports and can drive multiple large screens. Each large screen can also perform multi screen segmentation.
The monitoring workstation is a computer installed with the monitoring management platform software, which is used to control the digital matrix for multiple mode image segmentation display. It can also control the digital matrix to splice four large screens into a single screen for use. It can also display any image in full screen by double clicking with the mouse. If the front-end camera is a ball camera, the rotation and zoom of the ball camera can also be controlled through the monitoring workstation. At the same time, the monitoring workstation can also retrieve and replay historical video data from the storage server. The monitoring and management platform software adopts a lightweight server architecture and has the powerful functions of platform level software. It can work on a single machine or run on multiple machines in a network without the need for complex databases, and its superiority far exceeds that of the standalone version software. The functional description is as follows: • Adopting a "server+client" architecture, with user permissions, front-end devices, and recording plans,
