System Example (Switching streaming video)
This is a system example with 8 cameras and 4 monitors, and switching streaming video using a PC.
Refer to the "SWITCHING STREAMING VIDEO" section of "HOW TO USE THE CGI COMMANDS" on page 90 about
the CGI command to switch streaming video.
Note:All the "DESTINATION PORT No." of each encoder should be the same. The IP addresses to be assigned for
"DESTINATION IP ADDRESS" should be different according to the respective VIDEO IN connectors.
If connecting two or more encoders by using a switching hub (layer 2 switch), employ the following recommended
addresses.
•239.192.10.1 to 239.192.10.128
•239.192.11.1 to 239.192.11.128
