Notes
Surveillance Station throughput is tested with Axis network camera, using continuous recording with live view from Surveillance Station and motion detection by camera. Live view and recording are sharing the same stream from the camera.
Total FPS may be affected by other services running at the same time (e.g., archive tasks performed by Archive Vault).
The maximum channel number also includes devices installed on Virtual DSM.
