DHCP
Select DHCP (for Dynamic IP Addressing) to enable this feature. The DHCP server or a router
automatically assigns the unit an IP address and other appropriate TCP/IP settings. After connecting to the
network, view the assigned IP address by selecting
DESCRIPTION
from the
SYSTEM
menu.
If the network connection does not offer additional IP addresses, use an IP sharing device to remedy the
issue. Port-Forwarding may be necessary in order to connect to this device. Also, if a firewall is deployed in
the IP sharing device, the selected ports must be opened to the outside network. For more information on
Port-Forwarding, see the documentation for your IP sharing device (router) or contact your local authorized
vSync DVR
distributor.
ADSL
vSync DVR
supports direct PPPoE connections to ADSL modems without a router. The following
information is required. If you do not have this information, contact your network administrator.
Table 3.7.2.2. Network Parameters for ADSL
Item
Description
ID
The user ID for the ADSL connection
PASSWORD
The password for the ADSL connection
The ADSL modem connection must have an RJ-45 jack to connect to the DVR (USB Networking is not
supported).
Sharing an ADSL connection with other devices requires an IP sharing device such as router. In this case,
select LAN as the NETWORK type. Port-forwarding is required in order to access the
vSync DVR
through a
GATEWAY/Router and/or Firewall. See the documentation for your IP sharing device or contact your
network administrator to learn more about port-forwarding. If your router has QoS (Quality of Service) and
gaming feature, you may want to enable this for the IP address of the DVR. Some ISPs block some ports
commonly used for streaming video. If your ISP blocks the default port, simply change the port number to an
unblocked port. See the ISP technical support web page for additional help troubleshooting blocked ports.
