If you have 2, 3 or 4 webcams, then you can have 2, 3 or 4 instances of CAM Wizard running at the same time on your PC, each instance can be configured to use the relevant video source in the hardware setup screen.

If you look in the start menu for cam wizard as shown on the right, you will notice program shortcuts for 4 different cams.

This method for multi cam use gives you great flexibility as you can configure each of the instances of CAM Wizard to archive to different folders, email to different addresses, etc.

The screenshot on the right shows four instances of CAM Wizard running on the desktop at once.
