Note:
Additional analysis algorithms with comprehensive functions, such as IVMD and IVA, are also available. Refer to the IVA documentation for more information on using these.
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.
Minimum object size
Specify the number of sensor fields that a moving object must cover to generate an alarm. This setting prevents objects that are too small from triggering an alarm. A minimum value of 4 is recommended. This value corresponds to four sensor fields.
