Frame rate
The DVR will also set the frame rate for you. Note that the max frame rate will depend on the
resolutions set and is limited by the process rates of each DVR model. For example, on the NW-
4CVI-2MP running its 4 cameras at 1920x1080 (FHD), channel 1 is set to 20 fps and channels 2,3,4
are all limited to 7 fps. The NW-8CVI DVR kits come with 8 higher resolution cameras which limits
frame rate as follows.

Higher resolution takes more space on the drive. So, your recording time will be shorter before it
starts to overwrite but you should consider that you may need to blow-up (digitally zoom) images to
recover details such as faces or car number plates, so the highest resolution you can get is usually
the best option.
Configuring Recording Storage Schedule
Select Main Menu > STORAGE > SCHEDULE > Record, the Record interface is displayed (see
graphic below).
The default setting is 24 hours recording for all channels. You can modify the settings if needed.
Choose motion detect or continuous video
Motion detect is set as default recording mode. This means that your cameras will only record when
they detect movement in front of them. This means you can record events rather than days of
nothing happening. This takes much less space on the drive, so you can keep weeks of events from
several cameras on your hard disk before it is overwritten by new video.
