Networked VGA Grid User Guide Configuration preset considerations
Channel and recorder index number behavior
Each channel and recorder has an index number. The first channel created on a system is channel 1,
subsequently channel 2, 3, 4, etc. Recorders are also created starting at index 1 with numbers incrementing as
new recorders are created. The channel (or recorder) index number is found to the left of the channel or
recorder name in the Admin panel:
Configuration presets that contain the channels configuration group specify the channels in the preset by
their index number. This means if you have channels 1, 2, 3 and 4 when you save your preset, applying that
preset will overwrite the configuration of your current channels with indexes 1, 2, 3 and 4. If prior to applying
that preset you also had channels with indexes 5 and 6, the configuration settings for those two channels are
erased when the preset is applied (because the preset only has 4 channels).
There are three areas where channel (and recorder) index numbers affect what happens when applying
configuration presets. Read
Recording and streaming statesRecorded files (in channels and recorders) and
Deleting channels for more information.
Recording and streaming states
The Configuration groups section of this chapter shows that each channel and recorder's recording and
streaming state is included in the channels configuration group. This means that if a channel is streaming or
a channel (or recorder) is recording at the time you create a configuration preset, it will immediately start
recording (or streaming) when you apply that preset. Similarly, if a configuration preset is saved when
channels or recorders are not recording (or streaming), those channels and recorders will not be recording
(streaming) when the preset is applied
This means a channel or recorder may stop recording or streaming as a result of applying the
preset.
For example, when applying a preset with channel 3 set to record (the same example applies for streaming):
