New Trensh SMART Ai Based POE Pair 4 Port + 2 Uplink Port AND 8 Port + 2 Uplink Port 16 Ports 100 Mbps Network Switch  (Black)

1. Poe switches support poe devices and non-poe devices. But when connecting passive poe device or non-poe device, the switch can only transmit data and cannot power your device, so the connected device needs to be separately powered. Or you can use it with active poe splitter. PoE switch have professional lightning protection design-up 4KV port and power supply thunder prevents, with two levels of protection design respectively, effectively restrain the power of lightning from cable, which equivalent to give the entire network monitoring system with a security fence. 3. When the data or power transmission between the poe port and the terminal device is abnormal, the corresponding poe port of the device will automatically detect the problem and restart the connection. 4. Extend function extending max power and data transmission distance from 100 meters(330ft) to 250 meters(820ft), which is easy to expand network via ethernet cable to somewhere without power supply but need fix device such as IP Cameras.
