Notes| Surveillance Station 9.1.3 or above is required to support the maximum
IP cameras and FPS figures listed.
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 maximum number of camera stream outputs is 2 times the suggested maximum number of IP cameras. Performance metrics improve with the addition of expansion units. For detailed figures, please refer to this article.
