Chapter 10: LDVR-3U Network Recommendations
and Requirements
If your digital video system is intended for a distributed network environment,
proper network operation and configuration are critical. Although this topic is far
too broad to be described in detail and falls beyond the scope of this guide, the
following recommendations should help network administrators build a fast and
reliable network with minimal investments in time and resources.
• Make sure that all client workstations and servers are properly wired to the
network and can communicate with each other using the TCP/IP protocol.
Use the PING command in the Windows DOS command prompt or the
Network Neighborhood browser to verify this.
• For medium- and large-scale networks (5 or more stations), it is highly
recommended to have a Windows 2000 Server as a part of the network or its
segment. The Windows 2000 Server with DHCP and WINS services enabled
and properly configured allows all client workstations and servers (except
LEVS-3U's) to automatically obtain proper IP addresses and other
parameters as soon as they join the network. Use the command IPCONFIG/
ALL in the Windows DOS command prompt to display the complete
configuration information for your TCP/IP network connection.
Note: LDVR-3Us should not be configured for DHCP because an IP address is
already assigned to them. See the “LDVR-3U Default Settings” section.
• If the DHCP server in the network or its segment is not available, a static IP
address, subnet mask, and optional gateway address must be assigned
manually for each computer in the network.
The range of IP addresses is usually defined by local Network Information
Center (NIC) authorities, Internet Service Provider (ISP), or similar
organizations. Even if you plan to have an isolated network segment (not
physically connected to the world-wide network), it is a good idea to use
either very low or very high addresses with subnet masks defining a minimal
possible network segment in order to avoid conflicts with addresses in use
elsewhere.
Sometimes, it is impossible to shut down the services on an LDVR-SP recorder.
The most likely reason for this is that the Communication Server continually tries
to start the recording services if they are not running. So the process of shutting
them down will not work because the Communication Server simply starts them
back up.
The Communication Server can be set up so that it does not try to restart the
video server services in 1 of 2 ways:
1. The user who is logged into the Communication Server computer or the user
who starts the Communication Server should NOT be an administrator on
the video recorder. If the user is an ADMINISTRATOR, he will have remote
