D) Recording schedule
After connecting the storage, make sure that recording from the IP camera is enabled in
the
Config > Channel Parameters > Schedule Record
. By default, continuous recording
is configured. The recorder also allows you to save memory space by recording on selec-
ted days of the week or only when motion is detected (requires a camera that supports
motion detection).
E) Calculating storage capacity
The length of the recorded video material depends mainly on the disk capacity and bitra-
te of the video stream. Bitrate is the amount of information that the camera sends to the
recorder (depends on resolution, frame rate and image quality). Bitrate configuration is
set in the camera settings. The bit rate can be variable (VBR) or fixed (CBR).The current
instantaneous flow rate can be checked in the menu.
Config > System > Stream Info.
Formulas for calculating the recording length for one camera
MB/h = Average Bitrate * 3600s / 8000
GB/day = MB/h * 24h / 1000
Required storage capacity = GB / day * required storage period
