The role of switches/optical transceivers/industrial switches in security systems: Security dedicated switches are network transmission equipment developed for the actual needs of high-definition monitoring of security networks. 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 smooth transmission requirements of large-traffic network video signals for security monitoring. Therefore, security monitoring systems have higher requirements for network transmission equipment such as switches. requirements.
In the video security monitoring system, what is the role of the switch/optical transceiver/industrial switch? The switch has a high-bandwidth back bus and internal switch fabric. The switch can also be used to “segment” the network. By comparing the MAC address table, the switch allows only the necessary network traffic to pass through the switch. Through the filtering and forwarding of the switch, the collision domain can be effectively reduced, but it cannot divide the network layer broadcast, that is, the broadcast domain.
Security special switches/optical transceivers/industrial switches need to meet four “benefits”:
1. Conducive to the transmission of high-definition video streams,
2. Conducive to networking,
3. Conducive to adapting to the project site environment,
4. Conducive to installation and maintenance.

Notes on installing switches/optical transceivers/industrial switches switches/optical transceivers/industrial switches
1. The switch/optical transceiver/industrial switch room should be dry, ventilated, free of corrosive gas and strong electromagnetic interference.
2. The humidity of the switch/optical transceiver/industrial switch room should be kept less than 80%, and the humidity should be constant at about 25 degrees Celsius. Corresponding facilities should be installed when conditions permit.
3. The grounding of the switch/optical transceiver/industrial switch should follow the grounding requirements described in this manual, and should be grounded separately and well.
4. The voltage of the switch/optical transceiver/industrial switch should be stable to prevent the switch from working abnormally due to sudden changes and fluctuations in the power supply voltage.
5. A corresponding distance should be maintained between switches/optical transceivers/industrial switches and other equipment, and it is forbidden to stack other equipment and switches.
6. The connection cables between the switch/optical transceiver/industrial switch and the patch panel should be standardized and reasonable, and the patch panel (box) jumper should be concise and clear to prevent parallel lines and serial lines. Security lightning protection devices should be installed on the lead wires inside and outside the distribution frame.
When we install the switch, we should keep the computer room very dry, and the computer room should be relatively ventilated.
In addition, switches/optical transceivers/industrial switches also have voltage requirements. Generally speaking, the voltage should be kept stable. When installing, you also need to pay attention to keep the switch/optical transceiver/industrial switch and other equipment at a distance. In short, there are many precautions for installing switches/optical transceivers/industrial switches. You should understand them well before installing them. This will make it more worry-free to use.
