Blue Iris

Hello.
I have a total of 20 cameras and have those up on a TV. Obviously every camera is small, because it's a lot of cameras. Is there any way I can divide my cameras to "4cams x 5slides" and make those spin every lets say 15 seconds? This way I will have only 4 cameras on screen what would make a very big difference. If this is possible, please tell me how can I do that. Thank you.

Create groups of cameras. Then select the settings for each group (upper right, select the group and click on the gear). Select "participate in group cycle" for those groups you want to cycle. Now, when you select All Cameras Cycle in the Web UI, it will cycle the groups instead of cameras. There is a setting for delay between cycles for each group.
