General configuration of the detection tool is performed on the the Detection settings tab on the settings panel of the Equipment detection (PPE) object.

1. In the Min person height, % and Min person width, % fields, enter the minimum height and width of a person in the frame as a percentage of the frame height/width. Objects smaller than the specified size will not be detected.
2. In the Frames processed per second [0.016, 100] field, set the number of frames per second that will be processed by the detection tool.

3. In the Number of frames for analysis and output field, enter the minimum number of frames on which a violation must be detected in order to generate a trigger. The value must be in the range [2; 20].

4. By default, the One event per equipment element checkbox is set, and the detection tool triggers once for each equipment element violation within an object (track). If you want the detection tool to trigger each time an equipment violation occurs, clear the checkbox.

   Info
   title Note
   Example. A person appeared in the frame without a helmet, then put it on and then took it off again. If the One event per equipment element checkbox is set, then there will be one trigger, if not—two triggers.

5. Set the Show objects on image checkbox if it is necessary to highlight checkbox to frame the detected object with a frame objects on the image in the Monitor interface object windowdebug window (see Start the debug window).

6. Set the Save tracks to show in archive checkbox to save the object (track) to the archive.
   

   Info
   title Note
   The frame on the image of the detected object is saved in the Monitor object archive.

   
   

7. From the Working mode drop-down list, select the device on which the neural network will operate: CPU, one of NVIDIA GPUs or one of Intel GPUs. The default value is CPU. Depending on the device that you select, the neural networks will be selected.
   

   Note
   title Attention!
   It may take several minutes to launch the algorithm on NVIDIA GPU after you apply the settings. You can use caching to speed up future launches (see Optimizing the operation of neural analytics on GPU). If you specify other processing resource than the CPU, this device will carry the most of computing load. However, the CPU will also be used to run the detection tool. If you select Intel HDDL, due to the features of the device, only the segmenting neural network will be processed on it, the CPU will be used to run the classification neural networks.

    

8. Set the PPE detection checkbox to detect the presence of personal protective equipment (PPE). By default, the checkbox is clear.
