Systems and methods for detection of license plates using mobile dashcams are disclosed. The system includes a mobile device installed with a dashcam app connected to a server and a law enforcement agency through a mobile network. The dashcam app maintains an on-device database of vehicle data. The vehicle data is obtained from a server after pre-computation of the detection parameters from the issued Amber Alerts on the server-side. This enables the detection task to be more computationally feasible on the mobile device. The method includes detecting a vehicle that matches the description provided in Amber Alerts. The user is alerted of a matching vehicle and prompted with options for sharing the dashcam data with a law enforcement agency. The systems and methods disclosed herein allow for detection of a matching vehicle even in the absence of a network or a poor mobile network.
