Supports powering millions of high-definition network cameras through UTP Category 5 and above unshielded twisted pair cables. Four 10/100 Mbps auto-sensing RJ45 downlink ports support 802.3af/at standard PoE power supply. 2 10/100 Mbps uplink electrical ports, convenient to connect to the optical fiber backbone network, greatly expand the scope of application of the equipment. Support one-key video monitoring mode to achieve mutual isolation between downstream ports, suppress network storms, and improve network performance. Intelligent detection and identification of powered devices and output of the corresponding POE power, do not damage non-powered devices, never burn equipment. The PoE port supports a priority mechanism. When the remaining power is insufficient, the power supply of the high-priority port is given priority to avoid overloading the device. The maximum PoE output power of the whole machine: 65W, the maximum power supply of a single port: 30W Users can easily understand the working status of the device through the power indicator (POW) and each port status indicator (POE/Link). Plug and play, no configuration required, simple and convenient.
