To configure theWater
...
Level Detection, do the following:
- Go to the Detection Tools tab.
- Below the required camera, click Create… → Category:
...
- Production Safety → Water Level Detection.
By default, the detection tool is enabled and set to detect the water level in the frame.
If necessary, you can change the detection tool parameters. The list of parameters is given in the table:
| Parameter | Value | Description |

- Set the measuring
- Starting with Detector Pack 3.11, Intel HDDL and Intel NCS aren’t supported.
- On the measurement scale (9, 10), set the top and bottom visible values in normal conditions. The value should be in the range [0; 19].
- Move the anchor points in the preview window:Set the measurement scale in the frame.

values of the measurement scale should match the actual settings (see step 9)When specifying the measuring scale, its top and bottom
borders must match the values specified in the Visible bottom value and Visible top value parameters.

Configuring the Water level detection tool Level Detection is complete.
When you have created a the detection tool, you can see a sensor on the layout in the video surveillance Surveillance window.
If the sensor icon is green 
, the water level is lower than both critical and high marks. If the icon is orange 
, the water level is above the high mark, but below the critical mark. A red icon 
means that the water level is above the critical mark.
You can also add a numerical value of the water level to the video surveillance Surveillance window (see Configuring display of water level detection).
