 # 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.
 
 ## 🚀 Features
 
-- 🎥 RTSP camera stream input
+- 🎥 MJPEG camera stream input
 - 🧠 YOLOv8 person detection
 - 🔁 ByteTrack object tracking
-- ➕➖ In/Out counting via virtual vertical line
+- ➕➖ In/Out counting via virtual line
 - 📊 Prometheus metrics at `http://localhost:9100/`
-- 🌐 Streamlit UI for live video and statistics
+- 🌐 Web UI for live video and statistics
