The “recording buffer” allows user to configure the “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.
Note: The “Pre-alarm” function only works when the “Continuous” recording is also
activated.
Recording frame rate allows you to set different frame type for recording. Instead of
recording all the frames delivered from the camera, you might choose to record the I Frame
only. Recording only I Frame will help you to reduce the total storage space but decrease
the frame rate of the recorded video. Use the drop-down menu and select one of the
pre-defined types for your needs.
