CCFC Field Camera
27
Capture Modes
allows a user to set how the media event will be captured.
The
External Trigger
and
Motion Detect
configuration pages include an option
labeled
Pre-Record In Seconds
. By entering a value between 1 and 30 in this
field, the CCFC will begin buffering video in its camera memory. When an
event occurs, the CCFC will store the set number of seconds of video to a file
and continue recording the live video until the number of seconds has elapsed.
Video pre-recording allows the camera to record up to 30 seconds of video
leading up to a related capture event. This feature can only be used with
external trigger and motion detect capture events.
The use of pre-recording does impose some limitations on the functionality
available in the CCFC:
x
The pre-recording feature can only be used when the camera is in the
Fully On
power mode.
x
If the file caption is
Enabled
in the
Media
Settings
, it may be used as
part of the Pre-Record configuration and the file caption will be
visible in the
Live
Preview
on the
Dashboard.
x
If both photo capture and video pre-recording are configured for the
same event, video recording takes precedence. Only once the video
has been recorded will the photo capture occur.
x
The
Video Duration
is the total recorded video capture length up to a
maximum of 60 seconds. The
Pre
-
Record
Duration
is included in that
total. For example, if a
Pre
-
Record
Duration
is set as 5 seconds and
the total
Video Duration
is 10 seconds, the first 5 seconds of the video
will be pre-recorded.
12.4.1 Timed Capture
Timed
Capture
is used to configure the camera to capture photos or video using
the CCFC internal clock.
Figure 12-8 Timed Capture
When
Timed
Capture
is enabled, the CCFC uses its internal clock as a trigger
to initiate the capture of photos or video. In addition to the primary
Timed
Capture
event, there is also a second independent
Timed
Capture
. Each
configuration is independent of the other, but overlapping events may delay or
prevent one or the other from occurring. For example, 2 video recordings or
photo captures cannot occur at the same time. In the event that there are two
captures set for the same time, one will occur right after the other.
