I've used the DLINK AV1000 units for about two months now with great results. Transporting two 3MP IP cameras at 15 Frames/sec about 175 feet on 10/2 underground wire. I wouldn't make any guarantees until you can test the installation site and possible setup dedicated outlets for the adapters. I'd also bump up to the AV2000 units if I did it again since they add the ground pin and have more data bandwidth for the future.
