Recognition Options

  • In Zone trigger type executes if an object of the selected type entered the empty detection zone (or initially occupied it) and was within it for the specified time.
  • Out of Zone trigger type executes if the object leaves the detection zone and stays outside for at least the specified time. The trigger does not execute if at least one object is still in the detection zone. The trigger executes only when the detection zone is completely empty.
  • Object Counter trigger type calculates the number of simultaneously detected objects in the detection zone. It triggers provided that the number of objects in the detection zone is greater than or equal to the specified parameter.
  • Presence Control trigger type is executed with the In Zone tag for each object that enters the detection zone (or initially occupies it) and remains within it for the specified dwell time. The trigger is then executed again with the Out of Zone tag when the same object leaves the detection zone and stays outside for the specified dwell time. This scenario is applied separately to each detected object.
  • Intrusion trigger type executes if an object entered the detection zone and was inside it for the specified time.
  • Crowd trigger type calculates the number of simultaneously detected Person objects within a detection zone over a set duration. The trigger considers the distance between Person objects to identify people gatherings and executes when the specified crowd density threshold is met or exceeded.

  • Select the Event Filtration checkbox to enable filtering out re-detections of the same objects
  • Select a server from the drop-down list to run the analytics
  • Select the tracker type:
    • Tracker with normal accuracy
    • Tracker with increased accuracy
  • Select an analytics model:
    • Quality
    • Performance
    • Head Recognition
  • Enter the recognized object storage time in the buffer (in seconds)
  • Set the minimum height of an object for recognition (in pixels)
  • Set the minimum width of an object for recognition (in pixels)
  • The Detector Accuracy setting is determined by the parameters of the original image. A High value is recommended for a low-quality image to increase the detection probability, and a Low value is better for a high-quality image to avoid false detection. The possible range is from 2 to 8, the value is 5 by default.
  • The Event Filtration option uses AI to compare potential new detections with the last 10 events, filtering out duplicates. However, it's advisable to disable this feature when expecting many similar objects in the frame.
  • The tracker with increased accuracy consumes more resources compared to a normal one. However, in scenarios where objects briefly overlap each other, it increases the chances of preventing the recognition of the same objects as new ones.
  • The Quality model provides exceptional detection quality at the expense of analytics performance.
  • The Performance model provides exceptional analytics performance at the expense of detection quality.
  • The Head Recognition model uses the head detector, as opposed to the Quality and Performance models which use the body detector.
  • The minimum value for the Tracker Buffer Time parameter is 10 sec. The default value is 20 sec.
  • The minimum value for the Min Object Height is 25 pixels. The default value is 25 pixels. The maximum value is limited by the frame height.
  • The minimum value for the Min Object Width is 25 pixels. The default value is 25 pixels. The maximum value is limited by the frame width.
  • Default parameters allow the production of analytics. To customize the analytics, set parameters as required.
