Almost all large and medium-sized security surveillance sites are covered by WiFi, and network cameras are also installed. Many large-scale sites are already using PoE (Power Over Ethernet) industrial switches. So what does a poe industrial switch mean, and what does a poe industrial switch do? This article will give you a brief introduction.
What does poe industrial switch mean?
POE (Power Over Ethernet) refers to some IP-based terminals (such as IP phones, wireless LAN access points AP, network cameras, etc.) without any changes to the existing Ethernet Cat.5 cabling infrastructure. ) A technology that can supply power to these types of equipment while transmitting data signals.
Simply put, POE industrial switches are industrial switches that support network cable power supply. In addition to realizing the data transmission function of ordinary industrial switches, they can also supply power to network terminals at the same time. In other words, the role of PoE industrial switches is mainly data transmission and power supply.
The poe industrial switch has simple wiring, no need to repeatedly arrange data transmission lines and power supply lines. The network cable can be extended up to 250 meters to meet the needs of long-distance security monitoring and power supply transmission, improve data forwarding efficiency and save time and space.
What does the poe industrial switch do?
PoE (Power Over Ethernet) refers to the technology of transmitting power to equipment through twisted pair in Ethernet. It does not need to modify the existing Ethernet wiring infrastructure. It can transmit data signals for some IP-based terminals while also providing such equipment. Provide DC power supply. Through this technology, power can be supplied to Internet phones, wireless base stations, network cameras, computers, and other devices that are inconvenient to set up a power cord.
Compared with traditional industrial switches, PoE industrial switches have the PoE function. Direct power supply through network cables greatly simplifies wiring and reduces costs. Through the remote power supply method, PoE technology eliminates the problem of installing a separate power supply device on each terminal device, making it unnecessary to deploy a separate power supply system for the device at the use site, which can greatly reduce the wiring and management of the deployed terminal device Cost has promoted the development of related fields and business development.
Simply put, PoE industrial switches can supply power to network devices such as network cameras and VoIP, so that they can avoid complicated power wiring, which not only simplifies construction but also is very convenient and labor-saving.
But PoE (Power Over Ethernet) power supply is not guaranteed to be easy to use. When purchasing, not only the number and power of power supply equipment, but also the power supply distance must be guaranteed within one hundred meters. If the selected PoE industrial switch has insufficient power or exceeds one hundred meters, or Poor quality of the network cable will greatly affect the monitoring project.
Now everyone should know what the poe industrial switch means, and its use and function are also very obvious. In short, poe industrial switches have strong data processing capabilities, and security monitoring has high requirements for the throughput and delay of industrial switches, which can meet the smoothness and stability of video transmission of multiple high-definition cameras.
