Configure This Computer
This menu item defines the standard settings used by your computer
when it accesses your recorder via the web interface. Each computer
has its own customized settings; these settings are stored locally
on each computer. However, because they are stored locally, these
settings are used for whichever Luma system you access with that
specific computer.
After adjusting your settings, be sure to click Save before switching
to another window.
Communications
The top five options determine how the video is transferred to your
system.
Protocol
TCP checks the network connection state and favors preserving data.
It places less importance on transmission speed. This can result in
lag, but is more stable and reliable.
We strongly recommend TCP whenever remote access is required.
UDP favors sending data quickly. It places less importance on
preserving data. It is faster than TCP, but should only be used with
strong, reliable network connections.
We recommend UDP only on isolated networks and VLANs. Do not
use UDP when remote access is required.
Stream Type
This setting determines the quality of the video sent to your PC.
Main stream means your system always sends your PC the highest
resolution video. This is a bandwidth hog.
Sub stream is a lower resolution and eases the strain on your
system, but does not provide the same detail.
Mixed stream uses sub stream for multi-channel viewing (where
high definition is wasted on the small screens) but switches to main
stream when you’re viewing a single camera.
We recommend mixed stream for best performance.
