RB2011UiAS-2HnD-IN PoE IP Camera

I see in the datasheet that the PoE output capability is described as:

“Power output 500mA on Port 10”

This is passive, yes? What options do I have if I wanted to power a 802.3af compliant network camera from this?

None, apart from using an standalone af POE with the camera. Passive POE doesn’t use any circuitry; af POE does.
