To configure the water level detection, do the following:

1. Select the created detection tool (1).
   
2. If the camera supports multistreaming, select the stream to be used for detection. Select a low-quality video stream to reduce Server load (2).

3. If necessary, change pixel dimensions (height and width) of the water level measurement window (3, 6).

   These parameters affect the detection sensitivity. Please change the default values only in case of incorrect operation of the detection tool. Particular values are set empirically.

   
   

4. On the measurement scale (4, 5), set the upper and lower visible limits in normal conditions.
5. Move the anchor points  in FoV:7

   1. to set the measurement scale;
      

      Upper and lower limits of the measurement scale must match the actual settings (see paragraph 4).

      
      

   2. draw a line to set the upper limit for water level upon reaching which the detection tool triggers an alarm
   3. draw a line to set the upper limit for water level upon reaching which the detection tool highlights the sensor icon in the Camera Window with yellow color.
6. Click the Apply button.

When you have created a detection tool, you can see a sensor on the layout in the camera window.

If the sensor icon is green , the water level is lower than both critical and warning marks. If the icon is yellow , the level is somewhere between critical and warning. A red icon  means a level above critical.

 You can also display numerical value of current water levels for the detector (see Configuring display of water level detection).
