I know the pluses and minuses of either choice. What isn't clear to me is if using a poe switch for 8 cameras, will it have increased network traffic and stress? I seem to remember something was said about constant network packets and communication being sent over the network no matter if you're activley viewing the cameras or not. That extra network traffic I do not want just for the sake of powering cameras. At that point, I'd rather put up with the drawbacks of poe in the nvr itself. Which approach causes less network stress?
