Network Port Setup
I-View Now utilizes one of the device’s network ports. The TCP port, which has a default of 37777, must be forwarded
from the Router/firewalls external interface to the DVR’s static internal address. Ideally, this port can be left as the
default value, but on a network where this external port is already in use. It may be necessary to change them.
In the I-
View Now Portal, the TCP Port should be set as the Video port.
If the ports must be changed
Navigate back to the Network Setup
Enter the new TCP Port number
Click OK to save settings
Router Settings
Router settings must be examined on a case by case basis. I-View Now requires one port to be forwarded to the Device.
This can be done Either through port forwarding or NAT (Network Address Translation) depending on what the
installation site’s router supports. With either of these router features, any unused/unfiltered External Port can be
forwarded to the TCP Port(also referred to as the video port). For example External Port 9000 could be forwarded to the
DVR on port 37777 internally. In this case, the default TCP port on the DVR itself could be left alone.
The other approach would be to forward external ports to the DVR using the same External Port and Internal Port. In
this case, the ports must be set on the DVR through Network Settings. Common ports used for forwarding the HTTP port
are 1024, 1025, 1026, 1027 or 8080. Common ports used for forwarding the Video/TCP port are 8010, 8011, 9000, and
9010.
For any of these situations it is the External IP Address and External Port numbers that must be entered into the I-View
Now “Installer’s Portal.”
Note: Any ports used must be unblocked in any firewall devices (typically just the router).
The TCP Port Setting Can be found in
the Network Settings interface
