If you are trying to power 3 PoE+ cameras outside which are about 300 feet away from the indoor power socket. How to find a better way to run the outdoor cameras?
You can choose Procet's ultra PoE either in 95W or greater than 95W and Procet's outdoor PoE switch with 3 PoE+ output port. Since the PoE Injector will give power and transfer the signal between the switch and the camera system.
