How do I get this into the class discussion board?
Hi John, I'm not positive what you mean by "a POE?" Are you refering to a POE IP camera device? If so, then it's not strictly necessary to use Cat6 for each individual IP camera to the NVR.
Cat6 provides better electrical characteristics than Cat5 demanded at higher bit rates. For example, 1Gbps, while within the specification, is pushing the Cat5 capabilties while Cat6 is designed to handle the greater bandwidth necessary for these higher bit rates. Cat6 at high bit rates is supposed to provide better immunity to noise and more consistent performance. Thus the instruction to use Cat6 for switch interconnections as those will aggregate traffic from multiple devices. But a single IP camera may only generate less than 10mbps, which is well within the capabilities of humble Cat5's lower bandwidth.
Note also that Cat6 is not just cable but also appropriate connectors and methods of wiring. So all components involved need to be considered for true Cat6 capabilities.

Thank you Matt, much appreciated.
I have 24 HD IP cameras running to a POE, from there I've got one CAT5e running to the NVR for all the cameras. I'm now thinking that it is such a short run and that would negate the need for CAT6

Thank you Steve
You're not missing anything, but I am. As soon as I saw your response I realized I could've figured this out myself.
Thanks for your help, greatly appreciated.
