M26 Camera Manual: Operating the Camera
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 specic 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
6MP resolution.
In MxManagementCenter, 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 mainbenet 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 advan-
tage of full image recording lies in the special functionality of the D14D, in that it can always
ensure the availability of a maximum size (full) image for later searches, 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 D14D cameras,
you should use at least MEGA resolution when storing. This will facilitate later searches in
MxManagementCenter. 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 aect
the live image stream as little as possible.
Fullimagerecordingo: 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.
