You can calculate the average speed of vehicles by setting up two cameras.
Figure 3-71
1. Select a camera, set the distance in [Relative distance], and then click [Add]. The unit can be set as
kilometer or mile. Here is an example of setting the distance. If you want to indicate 10 miles or 10
kilometers, type “10” in the filed. If you want to indicate 0.1 mile or 0.1 kilometer, type “0.1” in the field.
2. Repeat Step 1 to set up another camera, and click when you finish the setting.
3. In the Recognition Records filed, you can see the average speed displayed. Note that average speed has
a limit between 0 and 300. If the values you set in [Relative distance] do not comply with the limit, the
average speed will display “0” in the field.
