 # People Counter with YOLOv8, ByteTrack, and Prometheus
 
-This project implements a real-time people counting system based on object detection and tracking using [YOLOv8](https://github.com/ultralytics/ultralytics) and [ByteTrack](https://github.com/ifzhang/ByteTrack). It supports **RTSP input**, **in/out counting** using a vertical line, and exposes **Prometheus metrics** for integration with monitoring systems.
+This project implements a real-time people counting system based on object detection and tracking using [YOLOv8](https://github.com/ultralytics/ultralytics) and [ByteTrack](https://github.com/ifzhang/ByteTrack). It supports **MJPEG input**, **in/out counting** using either a vertical or a horizontal line, and exposes **Prometheus metrics** for integration with monitoring systems.
