Configuration: Network: More Settings
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 DVR 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 DVR 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 DVR. Port forwarding is a
technical and involved process, recommended only for
the technically inclined.
• The default port number is 8000, which is not used by
many other devices/programs. However, particularly if
you have another DVR or DVR-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 DVR.
• 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.
• 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:
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 is no 'right' port number(s) to use - any port number
will work provided the DVR 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.
