DHCP Explained Further
Unit will default to DHCP or static IP mode on initial power-up based on DIP
switch setting on the CPU card.
If DHCP is not enabled, the system will bring up the static IP address that is
assigned in the configuration file shortly after power is applied or when DHCP is
turned off.
If DHCP is enabled, the Eyz-On will make three attempts to acquire a DHCP
address from the DHCP server before falling back to a predefined IP address.
The
Eyz-On waits up to a minute each attempt to acquire a DHCP address.
Once an IP address is assigned the Eyz-On will broadcast the new address to
the DNS server. In addition, you can use the Eyz-On Camera Discovery Tool,
Eyz-On Discovery.exe, to locate Eyz-On cameras on your network.
If DHCP is enabled and it fails to get an IP address assigned, the Eyz-On will fall
back to either the static IP address assigned in the configuration file or if
zeroconfig ("Select Dynamic IP Address without DHCP server") is enabled the
unit will revert the zero configuration address of 169.254.x.x. If the user
’s
network has cooperating equipment then the unit will auto negotiate an IP
address with other items on the network.
Note: When using DHCP, the user must set up their DHCP to dynamically
update the DNS server when a new host name is assigned an IP address.
Information on specific setup depends on the DHCP/DNS used but generic
Microsoft information can be found at http://technet.microsoft.com/en-
us/library/cc787034(v=ws.10).aspx and information on Dynamic DNS can be
found at http://en.wikipedia.org/wiki/Dynamic_DNS
When using DNS the user may simply type the Eyz-On name
plus “.local” in the
space for the URL on the web browser to connect to the Eyz-On . There is no
need to enter the IP address as the DNS will resolve the system name field into
an IP address.
Multi-Cast (mDNS)
Unit will default to Multi-Cast enabled in either DHCP or static IP mode. On the
Settings->Network->TCP/IP page there is an option to enable/disable
"Broadcast local IP address using mDNS".
When mDNS is enabled Eyz-On will broadcast its name and IP address on the
local subnet. Web browsers (and OS's) that support mDNS will be able to use
