Troubleshooting - Swann NVR16-7200 User Manual

English
Q: I can't login to or unlock the NVR - it says my password is
wrong.
A: The default username/password combination for the NVR
is "admin" with the password "12345". If that doesn't work (and
you haven't set a password of your own that you've forgotten)
then something strange has happened - contact Swann
technical support (contact details are on the rear cover).
Q: The NVR will boot up and show live images, but there are no
menus being displayed. Why?
A: There might be a fault with one (or more) of the hard drives
installed in the NVR. Before the menu system is displayed, the
NVR attempts to detect what drives are connected. If there is
an ambiguous signal preventing the NVR from ascertaining
whether there is a drive connected or not, then it will keep
looking and waiting for the drive to respond.
If you've just installed a new drive, disconnect it and see if that
fixes the problem. You can also try disconnecting one drive at
a time to see if that one is the culprit.
Q: How do I eliminate false-triggers on my motion detection?
A: There's no guaranteed way to eliminate false triggers, but -
in the majority of cases - you can fine-tune the NVR's motion
detection settings to reduce the number of false triggers
you're likely to get. (See "Camera Management: Motion" on
page 28 for more detailed information about setting motion
detection.)
1. Mask any redundant movement. This includes obvious
things like trees blowing in the wind, roads with cars passing
and so forth. Some less obvious things which might cause
false triggers include: the "flickering" of screens, monitors
or fluorescent lights, reflections of movement in windows/
mirrors and so on, lights which are often turned on or off,
shadows passing and so on. We can't possibly imagine what
you're going to find in your unique circumstances, so we
encourage you to experiment.
2. Fine-tune your sensitivity. There's no substitute for getting
a volunteer to play the part of intruder and experimenting.
Some cameras are just more "touchy" than others; some
lighting conditions are harder to get the settings "right" for.
3. Adjust your image settings (see "Camera Management: Image"
on page 27). Unlike many image adjustment options, the NVR
pre-processes video, which means that, when the NVR looks
for motion, it's looking at your already processed images. By
reducing the amount of video noise in your image, you can
increase the accuracy of the motion detection dramatically.
Typically, the settings that most often require adjustment are
Brightness and Contrast.
Video noise is a problem with any video signal. It's the very
slight change in brightness and/or color of pixels between
frames, and it's commonly regarded as being "just one of
those things" when dealing with digital imaging. By tweaking
the brightness and contrast, you can usually remove a good
deal of this noise, as it tends to be most pronounced near the
blacks (the really dark bits) and the whites (the really bright
bits) of your images.

Troubleshooting

Q: I'm getting too many email alerts from the NVR.
A: There are a few things that might help, depending what's
generating the email alerts. Here are a few possibilities:
• The emails are for real events, however it is telling me
about it multiple times.
This indicates that the NVR is functioning properly, but that
the Interval setting for your email alerts is too low. Increasing
the Interval time will decrease the number of email alerts the
NVR sends.
• The NVR sends email alerts when nothing seems to be
happening.
This suggests that there might be something amiss with your
Motion Detection settings, or with the configuration of your
sensors (if used).
The most likely explanation is that there is something in view
of your cameras which is moving, or causes the illusion of
movement. Have a look at "Camera Management: Motion" on
page 28 for some more information.
• The NVR keeps reporting errors (such as Video Loss,
HDD Error or similar).
There seems to be a hardware or configuration fault with the
NVR. These are most often caused by a faulty (or simply poorly
connected) connection or cable. Check the integrity of your
cables and connections.
Q: I would like to use other network connected cameras with
the NVR, is this possible?
A: The NVR is guaranteed to work with Swann branded
network cameras only.
