Mainstream / Substream / Mobilestream
Main, Sub, and Mobile stream selections are available in certain menus or live viewing situations. Using this
menu, you can set the parameters used for each type of streaming selection. Your NVR will automatically sense the
style of camera connected to each channel, and offer the stream settings available for that camera.
Go to “Main Menu”

”Parameter”

“Record”
→“
Mainstream/Substream/ or Mobilestream” to enter into
the menu interface as shown in Picture 4-12.
TIP: Choose a high Frames Per Second (FPS) setting to view fast moving scenes or objects.
Select a higher bit rate to capture more details when needed. The overall logic is that there is a
maximum amount of information that can be processed per second by any NVR or DVR.
Allocating the resources available to each channel or camera allows you to customize your
installation to achieve the best overall results.
