In Auto PSIM, you can configure LP recognition by macros and motion detection. To do this, do the following:
- Go to the settings panel of the LPR channel object, corresponding to the activated module (see Activating the software module used for identifying the plates).

- From the Enable on drop-down list (1), select:
- Disabled—license plate recognition by macros or motion detection is disabled (by default). The LPR channel scans each incoming frame;
- Motion detection— license plate recognition by motion detection is enabled. It is used to reduce the load on the Server;
- Macros—license plate recognition by macros is enabled. When you select this option, the Entrance and Exit drop-down lists become available.
- from the Entrance drop-down list, select a macro that starts license plate recognition;
- from the Exit drop-down list, select a macro that stops license plate recognition.

- Click the Apply button (2) to save the settings.
Setting up LP recognition by macros and motion detection is complete.
