This article guides you through the process of using the license plate search feature in VORTEX Portal's Deep Search to efficiently locate and analyze vehicles based on their license plate information.
Which cameras are compatible?
The following VORTEX premium cameras can detect and recognize vehicle license plates.

How does it work?
VORTEX cameras have license plate recognition (LPR) algorithm running at the edge. When a vehicle is detected, the algorithm tries to detect the license plate location and read its license plate numbers. The detected license plate snapshot and license plate numbers are stored on the cloud for post-search.
In a search, users can key in partial or complete license plate numbers as one of the search condition. When a vehicle of interest is found, users can also click the vehicle snapshot to re-search the vehicle by the the combined vehicle attributes and license plate numbers information.
Using the license plate recognition feature:
In order to use the license plate recognition feature in the Deep Search interface in the VORTEX Portal, users can click the "license plate" tag at the top of the search results to display only results where a license plate has been detected.
License plate search results:
If two best shots—a vehicle view and a license plate view—are displayed in the search results, it means the vehicle’s license plate has been detected.
Vehicle view:
License plate view:
If only one best shot, the vehicle view, is available, it indicates that the license plate was not detected.
This could be because the license plate is not facing the camera, or the environmental conditions (such as lighting or viewing angle) prevent correct detection.
Plate number search:
To search for a vehicle by its license plate, users can enter complete or partial license plate numbers in the license plate search field.
This is an example of a search by partial license plate numbers, "26". Vehicles with license plate numbers that include "26" will be listed.
License plate 'Re-search' function
Similar to the people search re-search function, users can click on the best shot from a search result where a license plate is detected to search for similar vehicles. The following example demonstrates the cross-camera searching capability by license plate and vehicle attributes.
If you find that several re-search results show vehicles with license plate numbers that are not completely the same as the target one is because VORTEX AI will also provide search results whose license plate numbers, although not exactly the same, are judged to be quite close to the target one.
