My NVR is in the main building. I want to add two IP camera's to the front and back of a 2nd building. Can I run a cat6 cable from the back of the NVR to the other building then use a POE switch and hook up the other two camera's? Will that work? Will it cause any problems? I don't want to have to run 2 cables at 200' ea just for the camera's. I already have to run 2 cables at 200' ( 1 for Wireless Access Point and 2nd for one of the cameras )
