Multiple Camera CCTV/RTSP/Video Streaming with Flask and OpenCV
Streaming live video from multiple CCTV cameras or RTSP sources has become easier with the integration of Flask and Open-CV. This technology allows users to leverage their existing hardware, such as a laptop webcam or IP cameras, to create a seamless streaming experience. By using a simple setup that utilizes Flask as the web server and Open-CV for video capture, you can easily manage video feeds in a variety of formats.
Whether you're monitoring a business premises, keeping an eye on a pet, or just curious about live video streaming, this setup offers flexibility and convenience. It supports both local webcam feeds and external IP cameras, making it a versatile solution for many user needs.
Multiple Camera Support: Easily switch between different camera sources, including built-in webcams and external IP cameras, by modifying the RTSP link or channel number.
Simple Setup: Implementing the server is straightforward; leverage Flask to set up a web server and use cv2.VideoCapture for video streaming.
Real-time Streaming: Experience live video with minimal latency, allowing for real-time monitoring and interactions via the browser interface.
Browser Compatibility: View live streams directly in your web browser without needing additional software, making access easier on various devices.
Customizable Channels: Change the channel number to display feeds from different cameras, providing control over which camera view is active at any time.
Efficient Resource Usage: The use of Open-CV allows for efficient handling of video data, optimizing performance without overwhelming system resources.
Easy Integration: This system can be integrated with existing Flask applications, making it a versatile tool for developers looking to add video streaming capabilities.

Flask is a lightweight and popular web framework for Python, known for its simplicity and flexibility. It is widely used to build web applications, providing a minimalistic approach to web development with features like routing, templates, and support for extensions.
