Create Recordings
Your Networked VGA Grid can record the output from each channel. (See Recorders for information on
creating multi-track recorders using multiple channels.) Recordings are very robust and crafted so that even in
the case of accidental system shutdown, recording files are closed off and playable.
This section describes the following topics for creating and configuring recordings via the web interface.
l
Record a channel via the web interface
l
Record with a recorder via the web interface
l
Configure the type and length of recording files
l
Close the current recording file while recording
l
Control recording with a mouse
See Control with HTTP Commands and Control with RS-232 / Serial Port for information on controlling
recordings with third party tools. See File Maintenance to learn how to download the recorded files.
Recording can also be controlled via the tablet interface. See Control recording via the tablet
interface.
Recording basics
While recording a channel or recorder, a new file is created each time the maximum time or size limit is met.
Additionally, when recording a multi-channel recorder or a multi-source layout channel, a new file is created if
an additional source is added to the recorder.
Physically removing the source (e.g. unplugging it) or otherwise interrupting the signal to the source does not
affect recording, and the recording will include the configured No Signal image. Recording is stopped if the
channel, or all channels in a recorder, are made inactive by changing the channel configuration to "no source"
via the admin interface.
Each channel that has a source present uses some CPU power to encode the stream. You can avoid CPU
overload by setting up channels you intend to use but setting the source to "No Source" in the admin
interface. When you are ready to use the channel again, simply set the source and all your other configuration
is already set. This doesn't apply for multi-source layout channels which always need at least one source to
keep their configuration settings.
You can choose to create AVI, MP4, MOV or MPEG-TS recordings. See Configure the type and length of
recording files to learn how to change the recorded file type.
