I have a question about power over ethernet video cameras.
In a POE system, where does the power originate? I currently have a system with three switches that do not support POE. If I was to add a fourth POE capable switch downstream from a non-POE switch would a POE device work when connected to it? Does the power for the device originate at the POE switch?
Mike.
EDIT
Also - If I add a POE injector to the system will the non-POE switches then power a POE device?
