Wanting to put a camera on the far end of my house the connection to that camera wasnt consistent, kept dropping out and freezing- was going to plug a wireless extender in closer near that cam and move the NVR, then i thought, why not plug in an extender, then ethernet cable the camera to the extender and see what happens- well what happens is it starts working perfectly. Just plug in the cable and it connects itself. Since doing this my camera works PERFECTLY, now full signal to camera and freezing is gone. Before you go nuts moving ur cameras, or returning to store- try that. I ran the line thru a hole in the garage wall where i ran the camera and put the extender in the garage so not out in weather. Much better app than the First Alert security cam app we have in our barn this is much more "updated" no problems now, i love the system! Highly recommend giving it a shot!
