User manual AXIS CAMERA RECORDER 1.1

[. . . ] AXIS Camera Recorder User's Manual 2 AXIS Camera Recorder User's Manual About This Document This manual is intended for administrators and operators of AXIS Camera Recorder and is applicable for software version 1. 1. Later versions of the document will be posted to the Axis Web site, as required. Previous experience of networking will be of use to the reader when installing and using this product. Legal Considerations Camera surveillance may be prohibited by laws that vary from country to country. Check the laws in your local region before using AXIS Camera Recorder for surveillance purposes. Liability Every care has been taken in the preparation of this manual. [. . . ] It is recommended that any regions that should be excluded are from motion detection are configured before calibrating motion detection. See page 24. Detected motion is shown in the selected color Motion level indicator Alarm threshold Figure 5 - The Motion detection window. Motion Level Indicator - Indicates the current level of detected motion in the image. The indicator is green when the level is below the threshold and red when the threshold is exceeded. An alarm will be generated when the motion level goes beyond the threshold. Alarm Threshold Indicator - Indicates the selected motion alarm threshold. The Administrator Application Noise Sensitivity Slider - Adjusts the noise sensitivity level of individual picture elements (pixels). The noise sensitivity level determines when the change in light intensity and color (light change) of individual pixels should be considered noise (i. e. an insignificant change) and when it should be considered motion (i. e. In the live updating camera image, the pixels where motion has been detected are displayed with the selected motion color (green by default). 23 To get an idea of how this works, try dragging the slider to high and watch how the whole image turns green. Drag the slider back to the optimal position, i. e. , where only the pixels affected by significant light changes are shown with the motion color. Motion Sensitivity Slider - Adjusts the sensitivity to motion. This controls the alarm threshold and thereby determines the minimum size of an object that will generate an alarm. Drag the slider until the alarm threshold indicator is at the optimal position. Note: Some video cameras generate undesired noise in poor light conditions. To avoid generating undesired alarms, it may be necessary to reduce the noise sensitivity or to improve the lighting at the viewed location. 24 The Administrator Application Defining Motion Detection Exclude Areas Areas that should not be included in the motion detection area can be excluded from the image by marking the relevant areas in the Exclude Regions settings. Filled squares indicate that motion will not be detected here. Figure 6 - The Exclude Regions dialog. Clicking in the image with the left mouse button will exclude squares from the motion detection, as shown above, and clicking with the right button will include them. It is also possible to Set All - include all squares in the image in the motion detection, or to Clear All - exclude all squares from the motion detection. This will automatically detect and exclude "noisy" areas from motion detection. Note that motion detection must be reasonably well calibrated before this will work properly. Show grid - Shows or hides the grid lines. The Administrator Application 25 Setting Up and Using PTZ Preset Positions Up to 25 PTZ preset positions (PP's) can be created for absolute positioning PTZ cameras. These are then accessible in the Monitor application's control panel. For relative PTZ cameras, the number of PP's will depend on the Axis video server and the PTZ driver used. For relative PTZ cameras, only the PP's defined in the video server will be listed and available for use. The PTZ preset positions dialog box is activated from the camera settings dialog box by pressing the PTZ Preset Positions button. An absolute PTZ is device is one that is capable of keeping exact track of its own position, by using a coordinate Figure 7 - The PTZ Preset Positions dialog box. It is thus possible to command it to "go to xx, yy. " A relative PTZ device, however, can only move in relation to its current position, i. e. [. . . ] We will now use our events to activate a camera. Click the Scheduler button and the Camera/Alert Scheduler dialog appears: 1. From the Camera drop-down list, select the camera to be controlled by the created events. From the Start Event drop-down list, select the event that will start the camera (Door opens), and from the Stop Event drop-down list select the event that stops the camera (Door opens - timer).
