If you have created a water level detector for a camera (see Configuring the Water Level Detection), you can see the water level sensor in the Surveillance window.

You can also display numerical value of current water levels for the sensor. To do it, follow the steps below:

1. In the text field, enter "{0.00}" and additional text if necessary. For example, "Water level: {0.00}".
   

   If you enter "{0.00}", then a fractional number with 2 digits after the point will be displayed (see Displaying the number of detected objects).

2. To configure fonts, click .
   
3. Use buttons to scale up/down the text and the sensor icon.
4. You can move the sensor just as any other object (see Moving input and output icons in the Surveillance window).

When the layout is saved, you see the information displayed in the Surveillance window.
