Key Features of RTSP in CCTV
#Live Streaming: RTSP allows real-time transmission of video feeds from IP cameras to monitoring systems or recording devices. It supports various codecs (e.g., H.264, H.265) to optimize the video quality and bandwidth usage.
#Control Mechanisms: RTSP supports operations like Play, Pause, Teardown, and Record, enabling control over the video streams. These controls are crucial for live monitoring and playback of footage.
#Interoperability: RTSP is widely supported by various CCTV camera manufacturers and third-party software, making it a universal protocol for streaming and managing video across different systems.
#On-Demand Streaming: RTSP enables on-demand streaming, meaning users can request a stream when needed, reducing network load when cameras aren’t being actively monitored.
#Port Usage: RTSP typically uses port 554 for communication, and it can work alongside other protocols like RTP (Real-time Transport Protocol) and RTCP (Real-time Control Protocol) for managing the delivery and quality of the stream.
#Security Considerations: RTSP streams should be secured, especially in sensitive surveillance environments. Encryption (e.g., via HTTPS) and authentication mechanisms should be used to prevent unauthorized access.
How It Works:
▸The client sends a request to the RTSP server (typically the camera or DVR/NVR) to start the video stream.
▸The server responds and initiates the stream using RTP, which handles the actual media transfer.
▸The client can then control playback, seeking, and termination of the stream through RTSP commands.
Applications in CCTV:
▸Remote Monitoring: Security personnel can remotely access live camera feeds using RTSP, which is often integrated into Video Management Systems (VMS).
▸Recording Systems: NVRs and DVRs use RTSP to retrieve video streams from IP cameras for storage and later retrieval.
▸Mobile and Web Access: RTSP streams can be accessed via mobile apps or web browsers for on-the-go monitoring of #CCTV systems.
