This guide explains how to add an Edge AI LPR (License Plate Recognition) camera to Navigator, enabling licence plate detections to be logged within the Navigator software for recording, playback, and event searching.
This guide assumes that the Edge AI LPR camera has already been configured correctly and is successfully detecting licence plates.
Before proceeding, ensure that the installed version of Navigator is 5.0.0.80 or later.
Add the camera to Navigator using the standard camera addition process.
Once the camera has been added successfully, select Alarm Management from the Navigator menu.
Within the Alarm Management window, select ANPR Detection from the Alarm Input Management column and Text Overlay from the Alarm Output column.
This configuration enables Navigator to receive licence plate recognition (ANPR/LPR) events from the camera and display the detected licence plate information as a text overlay within the software.
By linking ANPR Detection as the alarm input and Text Overlay as the alarm output, Navigator can record licence plate recognition data alongside video footage, making it easier to search for, review, and investigate vehicle-related events during playback.
Next, ensure that ANPR Detection is selected in the Alarm Input Management column, then click Options.
The options' window will now open. Within this window, select Aida Server / IP Camera.
Under the Aida Server / IP Cam section, select Get Detections from Aida Server / Camera Directly, then click Auto Detect Aida IP Camera.
The Navigator software will communicate with the camera and automatically retrieve the connection details. Once the detection process has completed, the Server IP and Web Port fields should be populated with the camera's information.
Important: Do not change the Linked Channel setting from 1. This value must remain set to 1 at all times to ensure correct communication between the camera and the Navigator software.
After verifying that the camera details have been populated successfully and that the Linked Channel remains set to 1, click OK to save the settings and return to the previous menu.
You will now be returned to the previous window.
From here, select Group Settings.
Within the Group Settings window, enable the Show Guest option and then click Close.
Important: If Show Guest is not enabled, the Navigator software will only display licence plate reads for vehicles that have already been manually added to the Allowed, Denied, or Exclusion lists. Any new or unrecognised licence plates will not be displayed in the ANPR results.
Enabling Show Guest ensures that all detected licence plates, including those not assigned to a predefined list, are recorded and available for searching and review within the Navigator Software. This setting is recommended for most installations to ensure comprehensive licence plate logging.
Close all open windows. Navigator should now display licence plates detected by the Edge AI LPR camera as a text overlay on the corresponding camera channel.
As licence plates are recognised, the detected plate information will be displayed directly over the live video feed, making it easy to identify and monitor vehicle activity.
To customise the appearance of the displayed licence plate information, open the Alarm Management screen again and select ePOS/OSD.
Once the ePOS/OSD window opens, select Font Settings.
Within the Font Settings menu, you can customise the appearance of the licence plate text overlay, including:
- Font style
- Font size
- Font colour
Adjust these settings as required to improve visibility and readability against the camera image. Once the desired changes have been made, save the settings and close the window. The updated font settings will be applied to future licence plate detections displayed within Navigator.
