3.3.2 Full Image Recording
It is possible to record a
full image
, regardless of the live image stream that is being
displayed. This ensures that the recording always contains the full image of the lens used,
even though the operator may have used the vPTZ features to zoom into the image in
order to examine a specific detail.
This means that you can use the vPTZ features in VGA resolution to pan, tilt and zoom in
the live image while the camera is, for example, recording full images at 1 fps in MEGA
or QXGA resolution.
In
MxEasy
and
MxControlCenter
, the recorded full images may be prepared for the user
with the vPTZ functions (for example, panning and zooming in on an image detail such
as a doorway).
If
full image recording is not activated
, only the last displayed live image will be saved (save
what is seen). The
main benefit
of live image storage is to ensure that the full power of the
camera processor is used for live image correction and maximum frame rates. The
main
advantage of full image recording
lies in the special functionality of the D15D, in that it can
always maintain availability of a maximum size (full) image for later investigation, despite
vPTZ actions carried out on the live image. The mechanical limitations of motor-driven PTZ
cameras mean that they simply
cannot
provide this unique advantage to the user!
Notes
Post-event search in the full image:
If you are using full image recording on D15D
cameras, you should use at least MEGA resolution when storing. This will facilitate later
searches in
MxControlCenter
or
MxEasy
. The advanced distortion correction features
require this function to deliver satisfactory image quality.
Full image recording on:
Due to the increased processing time, full image recording
reduces the data rate of the live image stream, which may drop by around 10 to 30
percent. We therefore recommend reducing the frame rate for storage as much as
possible to affect the live image stream as little as possible.
Full image recording off:
The event that triggered a video motion (VideoMotion VM)
window may not be in the recorded sequences while the window was not displayed
at the time.
