Automatic license plate and vehicle recognition for cameras, APIs, and custom applications.
Rekor Scout reads live video from most IP, traffic, and security cameras and provides real-time vehicle recognition results in any browser.
Rekor CarCheck accepts still images of vehicles and returns plate and vehicle information as structured JSON for easy integration into your own apps.
The platform returns plate number, make, model, colour, and direction of travel rather than the plate alone.
Search a retained database of detections by full or partial plate number, or filter by vehicle attributes, with up to 60 days of data retention.

Real-time vision AI models and a full platform to train, annotate, and deploy them
One model family covering detection, instance segmentation, pose estimation, oriented boxes, classification, and tracking, tuned for real-time inference on GPU, CPU, and edge devices.
Label data with SAM-assisted annotation, train on cloud GPUs with AutoTrain, and deploy to managed regions that scale to zero when idle.
Ship trained models to ONNX, TensorRT, CoreML, TFLite, and many other formats for cloud servers, mobile devices, and embedded hardware.
Adopt the open-source AGPL-3.0 release, or purchase an enterprise license to embed YOLO in closed-source products without copyleft obligations.
