Network video monitoring system
In this design plan, the video surveillance system is divided into the following sections. The basic functions and components of each part are as follows:
(1) Front-end video data acquisition part: Through the network camera to achieve the image acquisition of various monitoring areas; front-end video data acquisition equipment including infrared integrated network camera, network hemisphere, network smart ball, high-definition network camera, pole, wall hanging bracket And other equipment.
(2) Video data transmission part: The transmission network for the transmission of video image data shall be composed of super-quinant twisted pair cables, outdoor 4-core outdoor multi-mode armored cable, photoelectric conversion equipment and network switches, and the image data shall be transmitted through the transmission network. From the front-end monitoring equipment to the back-end monitoring center for video display and storage, the main equipment and wire include: network switches, photoelectric conversion equipment, ultra-five twisted pair, outdoor armored cable.
(3) Video surveillance center: The video surveillance center decodes the video image information collected from the front end by software, and converts it into an image signal and sends it to the monitor to form an intuitive image message and display it. At the same time, the video information is stored according to the storage strategy. . Through the network monitoring center management platform to carry out unified operation, configuration and management of the entire system, including the main equipment network monitoring center management platform, monitoring video host, large-size TV and other equipment.
(IV) Monitoring terminal part: The main function of the monitoring terminal is to monitor the real-time video screen, query playback video, capture images, and manual recording, mainly including monitoring clients and multi-channel video decoders.
Front-end equipment
(1) Video data acquisition equipment: HD network cameras, infrared network camera guns, infrared network hemispheres and other devices.
(b) Auxiliary equipment includes: mounting brackets, power supply equipment, etc.
Transmission network section
The network video surveillance transmission network mainly establishes the network electronic prevention and control video private network, and transmits video image data, front-end monitoring point control signals, and voice alarm signals through the Super Category 5 twisted pair cable to ensure clear and stable image information, and non-blocking and non-blocking of video data. delay.
Network Monitoring Management Center
Network Monitoring and Management Center Overall Design The network monitoring and control center platform has the functions of managing front-end and end-system equipment, video recording storage, equipment operation status detection, and video forwarding.

· Video stream forwarding:
· Video stream merge:
· Powerful management configuration features:
Expanded Metal Mesh
Expanded metal mesh are also known as metal plate mesh, diamond mesh, iron plate mesh, expanded metal mesh, heavy expanded metal mesh, pedal mesh, punching plate, aluminum plate mesh, stainless steel expanded mesh, granary mesh, antenna mesh, filter mesh, audio mesh, etc.
Surface treatment
• PVC dipping ( Plastic Spraying or Plastic Coating )
• Hot-dip Galvanizing
• Electro-Galvanizing
• Anodizing Aluminum Plate
• Spraying Anti-rust Paint etc
According to the hole type can be divided into
√ Fish-scale hole steel-aluminum metal mesh
√ Hexagonal hole steel-aluminum metal mesh
√ Fancy steel aluminum metal mesh
√ Tortoise shell-shaped steel aluminum metal mesh
Juntan Expanded Metals Mesh are made by sheets that are stretched and forming a raised diamond pattern.
