USB Camera

[longbow22]

Currently I have a non x10 camera connected to my VA12A adapter and am able to see video in AHP, my question is I want to add a couple more cameras that have their own usb adapter, can I use these with AHP or do I need to purchase a VA12A for each of my non usb cameras?

I found a x10 usb adapter on the web that you can plug 4 cameras w/audio and send x10 commands to it that will make it change cameras, but that only lets you view 1 camera at a time.

Thanks
