Hardware requirements for 1,000 ONVIF cameras
Computing and virtualization - 20 instances with 2 vCPU, 8GB each. It means we need a minimum of 40 threads = 20 cores with 160 GB of memory. It could be, for example, 1 Xeon with 28 cores (56 threads) and 256 GB. The overhead is for running Kubernetes.
Storage – 350 TB object storage. One camera with 1Mbps and 30 days retention is 0.33TB which results in ~ 350 TB. The storage server must support an object storage interface (S3).
Database – 2 core, 16GB RAM, 60GB storage. A database server must have an automatic backup.
