Control of X10 cameras is provided in the iWitness plug-in. If iWitness wasn't part of the ActiveHome Pro package you ordered, you should be able to get it very easily -- just call our sales line at (800) 675-3044. If you don't want to view cameras in ActiveHome Pro and just want to switch them on and off, you can use an appliance module in place of the XM13A; the behavior will be the same.
