The PoE extender can extend PoE network beyond 328ft without breaking TCP/IP protocols. There are single port and dual ports PoE extenders. What is the best option depends on your application. In this video, you will see when you should use the single port PoE extender such as working with PoE NVR. If the cable is being wired, you can choose the dual ports PoE extender to re-use existed cable. The power consumption is another factor as both ports will share the power coming over a single cable.
