The NetPro 16-port 10/100M PoE Switch is an enterprise-grade, power-over-ethernet device that delivers both data and power through a single Ethernet cable. It is specifically designed to power IP security cameras, wireless access points, and VoIP phones, eliminating the need for extra electrical outletsLong-Distance Transmission: Features an Extend (VLAN/Monitor) mode that allows power and data transmission up to 250 meters (at a reduced 10Mbps speed).Intelligent PoE: Automatically detects connected devices. If a non-PoE device is plugged in, it intelligently stops sending power and transmits only data to prevent damage.Plug & Play: Unmanaged architecture requires no complex configuration.DIP Switch Support: Often includes physical toggle switches for Normal, Default, and Extend/VLAN modes to isolate ports and restrict broadcast storms.
