PoE1500S PoE Adapter is fully compliant with IEEE802.3af standard. It delivers up to 15.4W output power per port. By using this device, both data and electrical power can be simultaneously delivered through a single CAT5 (or better) Ethernet cable to a non-PoE Ethernet-enabled device, eliminating the trouble to connect it to an outlet nearby with an external power cord. Above all, It could automatic detect whether the PD within the PoE receiving function, If not, it won't deliver power for safety. You can connect it to a wireless AP, Web cam (IP Camera), IP telephone, or other IEEE802.3af-compliant devices, (required by PoE1500S only), for the purpose of reducing installation cost and improving your network performance.
