12.2.2Analysis type
Select the required analysis algorithm. By default, only Motion+ is available — this offers a motion detector and essential recognition of tampering.
Metadata is always created for a video content analysis, unless this is explicitly excluded. Depending on the analysis type selected and the relevant configuration, additional information overlays the video image in the preview window next to the parameter settings. With the Motion+ analysis type, for example, the sensor fields in which motion is recorded are marked with rectangles.
12.2.3Motion detector
Motion detection is available for the Motion+ analysis type. For the detector to function, the following conditions must be met:
–Analysis must be activated.
–At least one sensor field must be activated.
–The individual parameters must be configured to suit the operating environment and the desired responses.
–The sensitivity must be set to a value greater than zero.
Note:
Reflections of light (from glass surfaces, etc.), lights switching on and off, or changes in the light level caused by cloud movement on a sunny day can trigger unintended responses from the motion detector and generate false alarms. Run a series of tests at different times of the day and night to ensure that the video sensor is operating as intended. For indoor surveillance, ensure constant lighting of the areas during the day and at night.
Sensitivity
Sensitivity is available for the Motion+ analysis type. The basic sensitivity of the motion detector can be adjusted for the environmental conditions to which the camera is subject. The sensor reacts to variations in the brightness of the video image. The darker the observation area, the higher the value that must be selected.
