Real-Time Streaming Protocol (RTSP)

RTSP provides a live video stream for live streaming applications between DW VMAX® G4 recorders and third-party software applications. RTSP streams offer a secondary backup location for recorded video and smart home integration, an alternative for ONVIF integration and a way to broadcast a stream to live streaming services, such as CCTV live monitoring in animal sanctuaries and public cameras.
