Requirements:

• Windows 2000/XP
• 512MB System Memory
• 5 GB free Hard Disk Space
• DirectX 9.0c or higher
• WDM/DirectShow compliant capture device or webcam

Recommeded:

• Windows XP with SP2
• 1GB System Memory
• 50 GB free Hard Disk Space
• Intel Pentium 4 2.8 GHz CPU or better

Note: The number of channels you can see is also limited by your capture devices. If you are just using USB-based webcam you generally can see at most 4 channels (also depends on the video resolution) because of the limit of USB bandwidth. If you want to connect 16 channels, you have to use PCI or PCE based capture cards, or mix using capture cards and USB-webcam.
