[Pre-Record Option (per camera)] Determines the number of pre-record frames.
„ Total Frames: Specify the maximum pre-recording frames of the system.
„ Frame/Sec Limitation: Specify the maximum pre-recording frame rate (fps) of a
camera.
Dividing the Total Frames by Frames/Sec Limitation, you will get the pre-recording
duration of each camera. For example:
Total Frames 30
Pre-recording duration =
Frame/Sec Limitation
=
6
= 5 seconds
[Pre-Recording using HDD] Use the hard disk as a pre-recording buffer. This method gives
you much longer pre-recording time.
Keep Pre-Record Files: Specify the number of video clips for pre-record. The maximum
number of video clips you can specify is 9, and the time range of one video clip is from 1
minute to 5 minutes. So the pre-recording time can be from 1 minute to 45 minutes.
„ Use Digital Watermark Protection: Click to watermark all recorded videos. Watermark is a way
to verify the authenticity of video streams, and to ensure that they have not been tampered with or
modified in any way. For details, see Watermark Viewer in Chapter 11.

Storage later in this chapter.
