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 maximum number of camera stream outputs is 2 times the suggested maximum number of IP cameras.
