NETMASK (SUBNET MASK): If the IP address is like a street address, then a sub-
network is like your neighborhood. This will be formatted in a similar way to the
IP address (ie. four numbers up to 255 separated by periods) but contain very dif-
ferent numbers. In the above example, the Subnet Mask might be something like:
"255.255.255.0".
GATEWAY: This is the address of the "way to the Internet" - to continue the road anal-
ogy, this is like your local access point to the highway. This is an IP address in the
same format as the others, and is typically very similar to the IP address of the DVR. To
continue the above examples, it might be something such as: "192.168.1.254".
DNS: "Domain Name System". Everything on the Internet is located via an
IP address - however, for ease of use, we associate domain names (such as
"www.exampledomainname.com") with those IP addresses. This index is accessible
in many locations online, and we call those locations "DNS servers".
DNS for STATIC confi guration: Under most circumstances, you can set
the DNS Server address to be the same address as your router (this is
usually the same address as Gateway).
DNS for DHCP confi guration: Typically, the DNS Server address will au-
tomatically be detected by the DVR. In some cases, you'll need to enter
a value - the address of your router (the same as the Gateway) should
work.
32 Remember: After making changes to the settings press/click the APPLY button.
You can choose how much footage the DVR will overwrite by selecting it from this
menu. You can set this as low as an hour (where the DVR will only keep up to an
hour's worth of footage at a time) or up to 90 days. Alternately, you can leave it on
Auto, in which case the DVR will overwrite footage as it deems necessary.
If overwrite is set to DISABLE the DVR will stop recording once the DVR is full. Whilst
you won't lose old footage, you run the risk of missing new events as they happen.
Be sure you want to do this before selecting it.
HDD FORMAT: Formatting the HDD will erase all data (i.e. footage) which is stored
on it, and re-create the FAT (fi le allocation table). There are some
times when using the format option is very useful. For example,
if the value displayed in TOTAL SPACE is not correct for the HDD
you've installed, or the DVR is displaying errors when trying to write
to the hard drive, then a format might fi x the problem.
USB FORMAT: If you have a USB fl ash drive connected to the DVR, this will format
it, allowing you to use it in the DVR for backup. This will also erase
all the data on the drive, but make the fl ash drive compatible with
the DVR for copying footage. To do this, click the USB FORMAT
button and click OK.
