The 802.3af compliant PoE feature makes installation easier by allowing the use of a single ethernet cable to both power the camera, and to carry images back to the monitoring station.*
* Cable runs of more than 100m will likely require a repeater to provide power to the camera.
The PoE feature eliminates the need to run additional power to the camera, lowering installation costs. This is especially useful in installations at sites without easily accessible AC outlets, like a parking garage.
