What's really needed here is input from somebody who owns the same cams & receiver as you do. That probably isn't going to happen here so I'll tell you what I can and also suggest you look around Swann's site for a Forum or knowledgebase...

It all depends on how the receiver's driver presents itself to Windows and DirectShow.

If the driver presents each camera it's receving as a separate device, that's good. If it is presenting only a single device, that is bad - it means the receiver is sending only one cam's video at a time to the PC and probably switching back and forth rapidly between cams.

You can probably figure it out by looking in Windows Device Manager. The receiver may appear as one (bad) or several (good) "Imaging Devices" or maybe as one or more "Sound, Video & Game Controllers".

Alternately you could use a DirectShow tool such as AmCap and just see what you get from the receiver. AbelCam is built upon DirectShow, and whatever you can see in AmCap is what you can see in AbelCam.

My guess? Probably the receiver will appear as only one device, meaning 2 receivers will be needed. But that is only an educated guess.

Licenses: you are correct - Pro enables 24/7 running of AbelCam with 1 camera. For each additional camera you need a Cam License.
