| My first question would be regarding Power over Ethernet or "Active Network". This is pretty critical for the network camera we are planning on, as each camera would otherwise require an external AC adapter, which would require that we run standard power outlets to EACH camera location. With PoE, we can simply run a Cat5 cable to the camera location and plug a PoE network camera in.
The way this works is with "injectors," or inline power supplies that insert a certain voltage into the Cat5 cable. I want to know if I can simply enable ALL ports on my 48 port switch to carry the voltage, or if this must be done for each individual camera line. |
