AXIS P1214-E Network Camera Detectors Note • Using the motion detection feature may decrease the product's overall performance. • The position of the Motion Detection Window is relative to the orientation of the Camera. Changing the orientation of the camera will also change the position of the Motion Detection Window. Set Up Motion Detection Windows To set up a motion detection Include Window, follow these instructions: 1. Go to Detectors > Motion Detection. 2. Select the Configure Included Windows option and click New. Select the new window in the list of windows and enter a descriptive name. 3. Adjust the size (drag the bottom right-hand corner) and the position (click on the text at the top and drag to the desired position) of the window. 4. Adjust the Object Size, History and Sensitivity profile sliders (see Motion Detection Parameters for details). Any detected motion within an active window is indicated by red peaks in the Activity window. 5. Click Save. To exclude parts of the include window, select the Configure Excluded Windows and position the exclude window within the include window. To delete an include or exclude window, select the window in the list of windows and click Del. Motion Detection Parameters The parameters controlling motion detection are described in the table below: Parameter Description High level (100%) Medium level (50%) Low level (0%) Recommended values Default values Object Size Object size relative to window size. Only very large objects trigger motion detection. Even very small objects trigger motion detection. 5-15% 15% History Object memory length. An object that appears in the window triggers motion detection for a long time before it is considered as non-moving. An object that appears in the window triggers motion detection only for a very short time before it is considered as non-moving. 60-90% 90% Sensitivity Difference in luminance between background and object. Ordinary colored objects on ordinary backgrounds trigger motion detection. A large difference in luminance is required to trigger motion detection. Only very bright objects on a dark background trigger motion detection. 75-95% 90% 24

Motion Detection Parameters
The parameters controlling motion detection are described in the table below:
Parameter
ObjectSize
History
Sensitivity
Description
Object size relative to window
size.
Object memory length.
Difference in luminance
between background and
object.
Highlevel(100%)
Only very large objects trigger
motion detection.
An object that appears in
the window triggers motion
detection for a long time
before it is considered as
non-moving.
Ordinary colored objects on
ordinary backgrounds trigger
motion detection.
Mediumlevel(50%)
A large difference in luminance
is required to trigger motion
detection.
Lowlevel(0%)
Even very small objects trigger
motion detection.
An object that appears in
the window triggers motion
detection only for a very short
time before it is considered as
