POE (PowerOverEthernet) means that without any changes to the infrastructure of CAT5 or CAT6 network wiring, it provides electrical transmission functions while transmitting signals for IP-based terminals. POE power supply is to provide power through the Ethernet interface connected to the cable. The way only relies on the network cable connected to the communication terminal to complete the power supply for them. This series of POE provides 48V voltage, and the transmission distance of AI smart selection power supply is as long as 100/250m. Using high-performance Ethernet switching main chip and PSE power supply chip combined with fast Ethernet transmission data signal and power supply function, and intelligent Ethernet POE power supply with AI intelligent management function, never burn the machine; with high backplane and capacity design, It has extremely fast data processing capabilities and smooth transmission of high-definition network data. Seiko steel alloy body electrostatic paint, promote dual-flow heat dissipation, stable performance and trouble-free work ≥ 30,000 hours; excellent port performance, simple installation. Support port fully loaded with IEEE802 3af/at standard power supply;  Gigabit POE line data: 12+/36-, power supply 45+/78; Managed POE switch supports SNMP protocol, WEB and other network management system platforms, easy to operate configuration switches and POE related parameter functions, provide safe transmission guarantee for video surveillance and network communication.
