I'm looking to get an 8 Channel NVR. It doesn't matter to me if it has built in POE or not. I see two options to choose from. Are there any other differences between these two NVRs other than number of channels and built in POE? Am I good to go with the 16 Channel one + a POE Switch (slightly cheaper), or is there something additional worth purchasing the 8 with built in POE? Thank you.
