Alarm Host IP: The location on your network where an IP-
based alarm system is hosted.
Alarm Host Port: The port associated with the IP-based alarm
system.
Server Port: This is the internal port that the NVR will use to
send information through. The most important things are:
• You'll need to enable UPnP on your router so your router
can selectively open these ports, allowing the NVR to
communicate via the Internet. If your router doesn't
support UPnP, you have two options. You can either get
a new router (which we'd actually recommend - UPnP
is such a good feature!) or you can manually forward
ports from the router to the NVR. Port forwarding is a
technical and involved process, recommended only for
the technically inclined.
• Nothing else uses this port. The default port number is
8000, which is not used by many other devices/programs.
However, particularly if you have another NVR or NVR-like
device, something might be using this port already. If this
is the case, change this value to be unique.
• You'll need to know this port value when logging
within your network or remotely - so, if you change it,
remember what it is!
• Make sure that the number used for the External Port
and Internal Port match, otherwise the UPnP function
will not work.
HTTP Port: This is the port through which you will be able to
log in to the NVR.
Like the RTSP port, it will need to be forwarded properly
•
in order to ensure smooth, latency-free communication.
The default value is "85", as this port is seldom used by
other devices or applications. If there is another device on
your network using this port, you'll need to change it to
be unique.
42
• You'll need to know this port value when logging
within your network or remotely - so, if you change it,
remember what it is!
Multicast IP: Multicast IP is a technique for one-to-many
and many-to-many real-time communication over an IP
infrastructure in a network. The receiver will receive data from
that IP without the need to contact individual devices directly.
In most circumstances this option is not required.
RTSP (Real-Time Streaming Protocol) Port: This port is
used to stream real-time images through, and is the port that
will be used to communicate with mobile devices. If you are
having issues streaming video to your mobile device or your
mobile service provider is blocking access, we recommend to
change this value to 5554. Do not change this if everything is
working ok.
What port number(s) should I use?
If the default port numbers are in use (85 and/or 8000) then the
simplest solution is just to keep "adding one" until you find a port
which is not in use. So, if 85 is already taken, try 86 or 87.
There's no "right" port number(s) to use - any port number will
work provided the NVR is the only device using it. For this reason,
avoid using port numbers 80, 81, 82, 88, 90, and 99 as these
are often used by other devices/programs/protocols.
