Full Image Recording - Mobotix M15 Manual

Virtual PTZ and Full Image Recording

3.4.2 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.
Live images
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 M15, 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!
Post-event search in the full image: If you are using full image recording on M15
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 because the window was not displayed
at the time.
