Configure text overlay

A text overlay shows the following event information in the live view: weekday, month, time, year, license
plate number.
1. Go to Settings > Image.
2. Activate Text overlay.
3. Set Overlay duration to a value between 1 and 9 seconds.
4. Select either date, time and license plate (Datetime + LP), or just the license plate (LP).
5. Check that the overlay appears in the live view.

Detect license plates in low-light conditions

Each detection gets a score by the algorithm, this is called the sensitivity level (confidence parameter). Detections that have a lower
score than the selected level will not show up in the list of events.
For scenes with low lighting you can lower the sensitivity level.
1. Go to Settings > Detection parameters.
2. Adjust the slider under Sensitivity level. To avoid false detections, we recommend that you lower the threshold value
with 0.05 at a time.
3. Check that the algorithm detects the license plates as expected.

Allow fewer characters on license plates

The application has a default minimum number of characters for a license plate to be detected. The default minimum number of
characters is five. You can configure the application to detect license plates with fewer characters.
1. Go to Settings > Detection parameters.
2. In the Minimum number of characters field, type the minimum number of characters you want to allow.
3. Check that the application detects license plates as expected.

Allow only exact matches of license plates

The matching algorithm automatically allows a deviation of one character when matching the detected license plate against the
allowlist or blocklist. However, some scenarios need an exact match of all characters of the license plate.
1. Go to List management.
2. Click to activate Strict matching.
3. Check that the application matches the license plates as expected.

Allow more than one character deviation when matching license plates

The matching algorithm automatically allows a deviation of one character when matching the detected license plate against the
allowlist or blocklist. However, you can allow more than one character deviation.
