About FPS ...
If you check Smart option in frames/sec settings for all cameras, all available FPS capacity will be equally shared depending on which cameras are recording at the moment. This option makes round-the-clock recording practically obsolete, and if you have random or low motion traffic in front of the cameras, it's not necessary to buy high FPS card to obtain high FPS recording for each camera.
Also, you can set different recording resolution by clicking green "play" button on the right from Recording quality slider.
