Introduction
Overview
This document describes how to connect SIP access control and SIP intercom devices to an NVR, mainly to realize video recording for industrial terminal products. The NVR client sends RTSP commands to the industrial video terminal, and the terminal returns the video stream of the built-in camera to the client for real-time video viewing and recording.
NVR stands for Network Video Recorder, which is the storage and forwarding component of a network video surveillance system. NVR works with video encoders or IP cameras to complete video recording, storage and forwarding functions.
