?After-Sale-Service?Every Reidubo switch is rigorously tested for reliability, quality, and performance. We supply a year warranty for whole products and lifetime technical support. ?VLAN Mode?In standard mode, all PoE ports are able to communicate freely and are suitable for normal data transmission. In VLAN mode, the PoE port is isolated from each other but communicates with gigabit uplink ports. If you would like to run multiple devices such as security cameras on the same PoE switch but want to keep them separate, the VLAN mode improves the transmission performance of local network data. ?Intelligent PD Detection& QoS function?The PoE switch will automatically identify whether the device connected to the port needs a power supply. If it is a non-PoE device that does not require power, the power of the port can be automatically turned off, which can protect the non-POE device from damage. When the PoE switch is transmitting data at full capacity, Quality of Service(QoS) enables POE switches to prioritize the transmission of important content for 1-2 ports. ?Unmanaged Plug and Play &Multiple installations options?Reidubo Gigabit PoE ethernet switch support automatically detects devices. only plug in the power cord and network cable without software installation or configuration, Supports desktop and wall. It can be installed in offices, homes, and businesses, it is a good choice for high bandwidth requirements. ?Built-in Power Supply & 4KV Lightning protection?Reidubo 18-port gigabit PoE switch built-in power supply (250W). the power adapter is no more needed, which makes the PoE Switch simpler and lighter.
