DIGITAL ZOOM
Digital zoom in video playback operates differently than it does in Live View as described
at the beginning of this chapter. Both are digital zooms where the image is electronically
enlarged - usually in exchange for a decrease in image clarity. You can digitally enlarge an area
of a video by clicking and dragging with the cursor on the area of interest. This action will draw
a green rectangle on the screen. When you release the mouse button, the cursor will change
to a magnifying glass.

Click within the border to zoom into the area.
If you need to re-draw the box, merely click
outside the area to dismiss the box and then
re-select the area.
In the case of a multi-screen viewing mode,
the zoomed-in view will fill only that portion
of the screen occupied by that channel. You
can switch to single-screen mode by double-
clicking on the screen as described earlier.
You can also go to full-screen mode and back
to multi-screen mode as well. Right-clicking
with the mouse will return you to the full
channel view.
VIDEO CLIP
This allows you to save only a portion of a video clip. For example; if you have a camera set
to record all the time and it captures some action in a five-minute segment, you can clip only
that portion and back it up. In addition to making an incident readily available, saving only the
portion of interest will reduce the amount of disk space needed to back it up.
STEP 1. Select a file to view in the normal manner.
STEP 2. Find the section of interest and press the Clip button (a)
STEP 3.
Drag the playback bar to the end of the section, or allow the video playback to
progress to the desired endpoint and press the Clip button again.
STEP 4.
Press the Backup button (b) to save the file to a USB drive connected to the
USB back-up port on the front of the NVR. It is not possible to save the edited clip to
the NVR’s hard drive.

BACK-UP
This process is different than the backup procedure described in Section 3.8 Backup at the
end of this chapter where one can back up saved files located across multiple days. Instead,
this procedure allows you to quickly save files or clips that you have located without having to
search for them again. Once you have backed up these files to an external USB device they
can be played back on a computer.

You must have a USB device connected to
the USB port on the front of the NVR before
proceeding.
STEP 1. In your file list to the right of the
playback screen, check the box next
to the file(s) you wish to save.
STEP 2. Click on the
Backup
button
( item b in Picture 3-36 ) and the
Backup window will open.
STEP 3. Your device will be listed at
the top of the window showing how
much space is available. Below it,
the list of file(s) you wish to back up
will be displayed along with type,
start and end times and size. At the
bottom of the window, the space
required to save the file(s) will be
displayed. You may uncheck any files
you do not wish to back up at this
time. The Remove button will remove
all the files from your list.
NOTE! The video files are in a proprietary format that will not play outside
the NVR without being converted to .avi format using the included General
Player software included on the Manuals and Software disc that came with this
NVR or available for free download at Q-See.com by searching for your model
number and looking under Software.
STEP 4. Press Start to back up your selected files.
Right-clicking the mouse will exit this window without saving the files.
Right-clicking with the mouse will exit the playback window.
