Wow. I had 4x Netgear Powerline 200Mbs adapters, so I had 2 unused. I plugged in two cameras into these adapters, then turned off the others and rechecked my speeds... having the two cameras connected via powerline was like they weren't connected at all. The speeds did not slow a bit compared to having all cameras off. So I agree that is the best solution. I just need to get a few more adapters and I'm set! Well, that and I need to figure out how to get the PTZ to work on these Amcrests (spectacular picture btw when you're use to the original foscams).
I wonder if I'll notice a big difference between 200mps and 500mps with these cams???
Hard to say, the speed is far from guaranteed though. My 500 Mbps kit usually links around 40 Mbps. It is kind of like wifi in that regard. The important thing is it keeps your camera video off the airwaves so your wifi still works when you need it for browsing / netflix / etc.
