Wuxi Dehang Technology shares with you Security monitoring In the system Switch Role of
The special switch for security monitoring is a network transmission equipment developed for the actual needs of high-definition monitoring of security network. The network monitoring project of Wuxi Dehang Technology Co., Ltd. is often in a complex and changeable application environment, and it is difficult for ordinary switches to meet the transmission requirements of security monitoring network video signals for real-time, integrity and smoothness. Therefore, the security monitoring system has higher requirements for network transmission equipment such as switches.
What role does the switch play in the video security monitoring system. The switch has a high bandwidth back bus and internal switching matrix. The switch can also "segment" the network. By comparing the MAC address table, the switch only allows necessary/necessary network traffic to pass through the switch. Through the filtering and forwarding of the switch, Wuxi Monitoring It can reduce the conflict domain, but it cannot divide the network layer broadcast, that is, the broadcast domain.
The security monitoring private switch needs to meet four "benefits":
1. It is conducive to the transmission of high-definition video streams;
2. Remote monitoring is conducive to networking;
3. It is conducive to adapting to the project site environment;
4. It is convenient for installation and maintenance.
Functions of switches in security monitoring system:
The special switch for security monitoring is a network transmission equipment developed for the actual needs of high-definition monitoring of security network.
Network monitoring projects are often used in complex and changeable application environments. It is difficult for ordinary switches to meet the real-time, integrity and smoothness transmission requirements of large flow network video signals for security monitoring. Therefore, security monitoring systems have higher requirements for network transmission equipment such as switches. The security private exchange is a network transmission equipment developed for the actual needs of high-definition monitoring of the security network.
Precautions for installing the switch
1. The switch room shall be dry and ventilated, free of corrosive gas and strong electromagnetic interference.
2. The humidity of the switch room should be kept less than 80%, and the humidity should be constant at about 25 ℃. If possible, corresponding facilities should be installed.
3. The switch grounding shall comply with the grounding requirements described in this manual, and shall be separately and well grounded.
4. The switch voltage should be stable to prevent sudden change and fluctuation of power supply voltage? As a result, the switch works abnormally.
5. Corresponding distance shall be kept between the switch and other equipment, and stacking of other equipment and the switch is prohibited.
The connecting cable between the switch and the distribution frame shall be standardized and reasonable, and the jumper wire of the distribution frame (box) shall be simple and clear to prevent parallel and cross wiring. The internal and external outgoing lines of the distribution frame shall be installed with security lightning protection devices.
