POE-G512V is 1 LAN-in (data + power) port and 1 LAN-out (data only) port Power over Ethernet Splitter that is designed to support Ethernet devices such as Access Points or IP cameras. It can provide four different types of DC power over existing Cat-5 cable to a device with an Ethernet port and solve the limit of the outlet location. It is a superb choice to boost your network with better performance and efficiency. By adding PoE devices, you can use an existing standard Cat-5 Ethernet cable to deliver both power and data where power source is difficult to obtain. It helps you reduce the time of installation and cost.
