Hello Erick Del Real Ramos
You can use Azure Video Analyzer to analyze and process video streams from Dahua cameras. Azure Video Analyzer provides a suite of video analytics and AI services that can be used to extract insights from video data. You can also use Azure Blob Storage to store the video data from the cameras.
However, backing up 80TB of information per month is a large amount of data and may require a significant amount of storage and bandwidth. You may want to consider using Azure Archive Storage or Azure Cool Blob Storage for long-term storage to reduce costs.
I would recommend reaching out to azure technical support for best practices on your case.
