6.4 Recording Configurations
The “recording configurations” gives users the overall control of how and
when a recording is performed and the quality of different types of recordings
performed on each channels. It can help the recorder to operate with
sufficient system resource by performing recording only when it’s necessary
with adjustable recording frame rate.
6.4.1 General Settings
You can define the following in “General Settings”:
. Pre-Alarm/Post-Alarm recording length
. Recording frame rate
. Define to always keep a number of days of previously recorded
data
. Enable/disable different recording types on different cameras
. Enable/disable audio recording
The “recording buffer” allows user to define “pre-alarm” and “post-alarm” time
for event recordings. The “pre-alarm” time sets the NVR to record in advance
when an event is triggered. The “post-alarm” time sets the NVR to continue
recording for a period of time after an event trigger is finished.
* The “Pre-alarm” function only
works when the “Continuous”
recording is also activated.
Recording frame rate allows you to set different frame rate for different types
of recording instead of recording at one frame rate only. Use the drop-down
menu and select one of the pre-defined frame rates for a particular recording
type.
