    1. How do you adjust the voltage range supplied by this power injector? How does this injector work IP cams that run on 5 volt DC and 12 volt DC?

    2. What is the power consumption of this PoE injector with no device connected, that is, the consumption of the injector itself?

    1. Because of the resistance of the ethernet wire - you cannot use 5v or 12v from the injector side. You need to send 24 volts or 48 volts down the wire, then step the 24 volts or 48 volts down to 5 volts or 12 volts at the camera end of wire - up to 328 ft away or 100 meters. Our POE-5v10w (equivalent to the WS-POE-5v10w) and POE-12v10w (equivalent to the WS-POE-12v10w) active splitters do this - just choose our 24 volt injector for 8, 12 or 16 ports. Further - look again at the specs of 12 volt cameras - if the spec says "12v, PoE" then it uses 12 volts if powered locally, and 48 volts when powered via the Ethernet cable.

    2. It is almost zero - the injector requires about 10 mw for the LED, otherwise none. The power supply is DoE Class VI so it requires less than 210 mw in standby.

    *This product is equivalent to the WS-POE-12-1U injector
