FASTCABLING 90W Outdoor PoE Extender 2 Port, Industrial Grade, Repeat 328ft PoE for Mesh, High Power PTZ Cameras, IP67 Waterproof, Complete Metal Design

The power will lose and be converted into the heat in PoE system. The longer the cable, the more power loss will come up. Choosing the pure copper type cat5e/cat6 but not CCA type is critical to reduce the power loss in long running POE system.
The remaining power budget doesnt equal to the power from PoE switch. The power loss needs to be considered. While working with high power PoE++ devices such as some WiFi 6 access points, infrared PTZ camera, the 60W PoE extension may be needed.
The surge could be absorbed by the cat5e/cat6 cable and transmitted to both ends. Grounding the PoE injector as well as the edge device can introduce the surge to the ground and protect your system from damage by the surge impact.
