Dahua’s License Plate Recognition cameras automatically capture vehicle license plate images, and recognize license plate numbers and letters
During playback, an operator can perform a license plate search by time and date to view thumbnail images of all plates captured during the specified time period, or they can enter a license plate number to search for vehicles recorded with that plate.
