Question:
How do you set the ip-ports for the 4 individual video inputs? I have a need for a device like this using (http://blueirissoftware.com/index.html) software. The individual camera setups can use the same ip, but need unique port numbers.

Answer:
i check that video output is a QCIF for 4 video at one screen, therefore, it's not possible to connect different port no. for one of the 4 cameras.
