General

The general sections describes the general settings for objectR

  • Enable License
    Enables the license for selected device.

  • Minimum object size
    Adjusts the minimum size of objects that are to be detected and classified by the system. Adjust this setting if small objects that should be detected are ignored by the system. Decreasing this setting to detect more small objects, but this may cause more false alarms. Increase this setting to ignore more small objects. Events may be missed.Possible values: Minimum, even less, less, medium, more

     

  • Contrast sensitivity
    Increase sensitivity to detect more objects in environments where there is low contrast between objects and the background. You are more likely to detect low contrast objects. When the setting is too sensitive for your camera view, you may detect more events that are not real events of interest. Decrease sensitivity to detect more events when there are many shadows or reflections in the field of view. You are less likely to detect low contrast objects. When the sensitivity is too low for your camera view, you may not be notified when some real events occur.Possible values: Minimum, even less, less, medium, more

     

  • Stopped objects monitor duration
    Decrease to ignore stationary objects sooner and save system resources. Increase to monitor stationary objects longer.If you change this value, remember to consider the impact on existing and new rules. If you set a Loiters or Left Behind rule to a duration higher than the setting value, the sensor will never trigger responses for objects that have been stationary the entire time they are in the view. For instance, you may have set the value to 1800 seconds (30 minutes). You create a rule to detect when someone has loitered for 35 minutes. A person that is stationary for the first 30 minutes does not trigger a response even if they remain stationary for more than 35 minutes. The sensor stopped monitoring the person at 30 minutes. In the next example, assume you set the value to 600 seconds (10 minutes). The rule is created with a duration of 15 minutes. An object is stationary for 5 minutes, moving for 5 minutes, and then stationary for 6 minutes. A response would be triggered because the object was never stationary for more than 10 minutes at a time. The stationary time must be continuous.

     

    Possible values: Minimum (5 minutes), even less (15), less (30), medium (45), more (60)
