FPS
Quality
Note: FPS and Quality recording settings will affect live stream viewing as well. For example, if 1 FPS and Low
Quality are set in the recording schedule, DW Spectrum will stream live as per selected settings even if the camera is
capable of more. If recording is not set, DW Spectrum will stream live at Maximum FPS and Quality.
Those settings are applied to Recording Schedule. See "Modifying Recording Schedule" for details.
It is possible to record I/O Modules as well (see "Setting Up I/O Modules"). In this case audio will be recorded, if a
microphone is connected to the module. To enable recording it is necessary to setup Recording Schedule for I/O
Module. It is similar to Camera Recording Schedule except Quality/FPS settings.
See also "Analyzing and Anticipating Storage Usage".
Dual Stream Recording Specifics (RADASS)
Some Recording Parameters may need Motion to be supported by the Camera. Motion + Low Quality Always
recording requires Dual-Streaming to be supported by Camera.
If Dual-Streaming is supported, the second stream settings are set automatically based on the main recording settings:
2 to 7 FPS
320p to 480p
Not only is the second stream used for recording, it is also used for Software Motion Detection and bandwidth and
CPU saving during playback. See "Setting up Motion Mask and Motion Sensitivity" and "CPU and Bandwidth Saving
during Playback (RADASS)".
If primary stream is 480p or less, it can be used for Software Motion Detection as well.
Modifying Recording Schedule
DW Spectrum provides a powerful and flexible schedule for configuring recording parameters.
A specific date and time can be set in the recording schedule as well.
Examples:
Workdays 8AM-8PM – record Always, 24 FPS, high quality
Weekends and Workdays 8PM-8AM – record motion only, 10 fps, low quality
The cameras recorded by Server s are marked with a small red circle in Resource Tree:
– camera in recording mode
– camera recording is setup, though not recording at the moment (a license is still being used)
Note: It is possible to configure Cameras for Administrators and Viewers that have appropriate permissions.To set
