Notes
DS223
  • Performance figures are obtained from testing conducted with the device fully populated with drives, with their default memory configuration, and under a continuous recording setup. Actual system capabilities may vary based on configuration, drive performance, enabled features, and the presence of additional workloads.
  • Use NVR Selector to quickly find a suitable model based on your requirements.
  • The number of video channels that can be viewed simultaneously is double the maximum number of cameras for the same codec and resolution.

  • The suggested maximum number of users is based on the following workload: 20% of users randomly perform file operations (upload, download, move, and delete), and 80% of users are logged in but idle. Learn more
  • Models with SSD support are tested with a single SSD volume.
  • Exceeding the recommended numbers above will not block application operations, but may result in longer response time.
  • Btrfs file system and non-encrypted shared folders were used during the aforementioned testing.
