Hardware requirements for neural analytics operation

To set up the equipment detection tool (PPE), do the following:

  1. If the camera supports multistreaming, select the stream for which detection is needed (1). 

  2. Select one or several files for the classifying neural network (2). There must be a separate classifying neural network to recognize equipment on each body segment.
  3. Set the interval between the analyzed frames - Delay between two measurements -  in milliseconds (3). The value should be within the range of 30 – 10,000.
  4. Select the Mask checkbox to display body segments in the preview window (4).
  5. Set the minimum height and width of a person (5, 6) in the frame as a percentage of the frame height/width (0,15 = 15%). Objects which are smaller than the specified size will not be detected.
  6. Select the processor for the neural network - CPU, one of GPUs, or Intel processors (7, see Hardware requirements for neural analytics operation).
  7. Set the minimum number of frames containing people with no PPE for triggering the tool - Number of measurements in a row to trigger detection (8). The value should be within the range of 2 – 20.

  8. By default, each equipment element's triggering occurs once during a continuous tracking of a human object.  You can set triggering to multiple by setting the One Event per Equipment Element parameter to No (9).

    Example. An individual not wearing a helmet appears in FoV, puts on a helmet, then puts it off. If the One Event per Equipment Element parameter is activated, you will have one alarm event, otherwise two.


  9. Select the segmenting neural network file (10).

  10. In the preview window, you can set the detection zones with the help of anchor points much like privacy masks in Scene Analytics (see Setting General Zones for Scene Analytics). By default, the entire FoV is a detection zone.
  11. Click Apply.

Equipment detection tool (PPE) is now configured. 

The equipment detection tool (PPE) triggers an alarm when a person not wearing required equipment (PPE) on specified body parts, or wearing inappropriate equipment, appears in FoV.
