Configuration: Network: UPnP / SNMP
UPnP (Above)
Enable UPnP: UPnP makes configuring your network easier
and faster. To use the UPnP setting on the DVR, you'll need a
router which supports this feature, with UPnP enabled. Note
that many routers which do support UPnP do not come with
the feature enabled by default. You may need to ask your
Internet service provider to turn it on.
When UPnP is enabled on your DVR and your router, the Ports
that the DVR requires to be open for access to and from the
Internet will automatically be opened and closed as necessary
by your router, saving you the trouble of manually forwarding
these ports. If UPnP is not enabled, or your router does not
support this feature, you'll need to forward the ports the DVR
uses from the router to the DVR - since this is a technically
challenging process; we strongly recommend using UPnP if
possible. Make sure that the number used for the External
Port and Internal Port match, otherwise the UPnP function
will not work.
Edit: Allows you to change the current External Port number.
Mapping IP Address: Will display the public IP address of the
router that the DVR is connected to.
Status: If UPnP is working correctly, you will see Active
displayed. If UPnP is not enabled or you haven't forwarded the
correct port number, the status will be Inactive.
SNMP (Below)
SNMP: Simple Network Management Protocol. If your
network is setup to use SNMP (if you're not sure, your network
administrator(s) should be able to tell you if this protocol is in
use) then you can configure it here.
Enable SNMP: Whether SNMP is in use. If it's not in use, then
ensure this stays disabled. The SNMP protocol can interfere
with normal networking functionality.
SNMP Version: The version of SNMP currently being used.
SNMP Port: The SNMP port currently being used. This is
typically port 161, however exceptions exist.
Read Community: Who has read-only access to information
on the network (can view, but not change).
Write Community: Who has control over information on
the network (can view, modify, change, create or delete
information).
Trap Address: The address of the network trap (the
asynchronous notification from agent to manager).
Trap Port: The port being used for the trap.
