Enabling and Disabling Recording
Recording is by default enabled.
To enable/disable recording for the selected item, select/clear the
Record
tab's
Recording
check box.
Recording must be enabled for the item before you are able to record (i.e. save) video or audio from the camera. A
rule (see "Manage Rules" on page 133) specifying that an item should record under particular circumstances will not
work if recording is disabled for the item in question.
Setting Recording Frame Rate—Camera Only
Specifying recording frame rate is only possible for MJPEG, a video codec (technology for compressing and
decompressing data) with which each frame is separately compressed into a JPEG image.
1. Select or type the required recording frame rate (in FPS, Frames Per Second) in the
Recording frame rate
box.
2. Clicking
the
Recording frame rate
box' up/down arrows will increase/reduce the value in increments of 1 FPS.
Tip:
If you click inside the
Recording frame rate
box, two decimals will be added to the value. By selecting the number
before or after the separator, you are able to increase/reduce the numbers in increments of 1 unit. This way you are
able to specify a very specific recording frame rate average over time, for example of 20.15 FPS:
Working with Prebuffering
Prebuffering is essentially the ability to save video and audio in the camera's or microphone's database before the
initial boundaries of a recording.
Use of prebuffering can be highly advantageous: It allows you to save video and audio from
before
the events or
times used to start recordings.
How Prebuffering Works for Cameras and Microphones...
If, for example, you have created a rule specifying that recording should start when a door is opened, being
able to see what happened immediately prior to the door being opened may be useful. Such prebuffering is
possible since RC-E continuously receives streams of video and audio from connected cameras and
microphones (unless the transfer of video or audio from cameras or microphones has in some way been
disabled). Storing video and audio from before the initial boundaries of a recording is therefore not a problem:
video and audio passes through RC-E anyway.
When prebuffering is enabled for a camera or a microphone, RC-E continuously records video or audio from
the camera's or microphones stream and provisionally stores it in the database for a specified number of
seconds before automatically deleting it— unless the provisionally stored video or audio turns out to be
required for a recording, in which case it is automatically added to the recording.
How Prebuffering Works for Speakers...
Unlike video and incoming audio, which RC-E continuously receives from connected cameras and
microphones, outgoing audio is only transmitted when Ocularis Client users press a button to talk through
speakers. This can, depending on which events or times are used to start recordings, mean that there will be
very little or no outgoing audio available for prebuffering.
Enabling and Disabling Prebuffering
Prebuffering is by default enabled; with a prebuffer size of 3 seconds. To enable/disable prebuffering, select/clear the
Enable prebuffering
check box. When enabling, remember to specify a prebuffer size.
Specifying Prebuffer
Select or type the required prebuffer size (in seconds) in the
Prebuffer size
box. Clicking the
Prebuffer size
box'
up/down arrows will increase/reduce the value in increments of one second.
