Manual Setup Step 1: Assigning a Permanent Local IP
Address
Manually assigning an IP address for your camera is
only necessary if your
router does not have the address reservation feature. As discussed earlier in
this manual, all current NetGear, LinkSys, Dlink and similar standard routers
have an easy address reservation menu. The Mac Quickstart section shows
how to use address reservation on a current generation Apple Airport.
If you have already reserved your camera’s IP address you would skip the
manual assignment of an IP address, so please skip ahead to the next section.
Old Apple Airport and old LinkSys routers, as well as many DSL modem routers
do not have the address reservation feature so in that case the manual IP
address setup as explained in this section is the only choice.
On your home network (LAN) all your computers and other network devices
have a local IP address. In every IP address there are 4 groups of digits that can
have a value of up to 255.
To pick a permanent address for your camera you first need to know your
router’s IP address. It is shown in your camera’s system menu (at the top of
the settings screen) if you scroll down to “Default Gateway”. The router’s IP
address determines the first 3 groups of digits for your camera’s IP address.
Now we need to select a valid number for the 4
th
group of digits. We don’t
simply pick a random number because we have to avoid numbers that are
already taken or that could be assigned by your router.
The router uses addresses in a range set aside for this purpose (called the
DHCP range). For many routers, this DHCP range is from 2 to 100 but you’ll
have to check your specific router’s DHCP menu. Sometimes this is shown as
start and end address, or start address plus number of available addresses.
Why is this important? We need to select an address outside this range to
make sure that your router would never pick this address for another device.
For example, LinkSys routers use a DHCP range from 192.168.1.100 to 149, so
you could choose 192.168.1.200 for the camera. Never use addresses that end
in .0 or .1, since that is reserved for your router, and never use addresses that
end in a number higher than 254.
