Used this ECP-01 set to keep existing coax runs and still get IP cameras working. It sends data plus PoE from the NVR out to the camera, and the 400m (1300ft) range is a big deal for the far end of my property. Video comes through clean at 8K quality, and the surge/short protection gives me some peace of mind outdoors. Installation was simplified since I did not have to pull new Ethernet. Solid professional CCTV build, and it saved me real money on cabling.
