Thanks for asking question! If you are looking to record a video using the Azure Continuous Record Video (CRV) by webcams. You might be aware of that Continuous video recording (CVR) refers to the process of continuously recording the video from a video source.
Adding some below findings related to this.
- Live Video Analytics on IoT Edge supports recording video continuously, on a 24x7 basis, from a CCTV camera via a media graph consisting of an RTSP source node and an asset sink node.
You may refer to the Tutorial: Continuous video recording to the cloud and playback from the cloud to use Azure Live Video Analytics on Azure IoT Edge to perform continuous video recording (CVR) to the cloud and stream any portion of that video by using Azure Media Services. - For Setting up Azure resources for Live Video Analytics on IoT Edge check: https://github.com/Azure/live-video-analytics/tree/master/edge/setup
- To accomplish CVR, you need to capture the video from an RTSP-capable camera and continuously record it to an Azure Media Services asset.
- for analysis feature like motion detect you may refer to this Quickstart: Detect motion, record video to Media Services which walks you through the steps to use Live Video Analytics on IoT Edge for event-based recording. It uses a Linux VM in Azure as an IoT Edge device and a simulated live video stream. This video stream is analyzed for the presence of moving objects. When motion is detected, events are sent to Azure IoT Hub, and the relevant part of the video stream is recorded as an asset in Azure Media Services.
