DHCP (Dynamic Host Configuration Protocol):
Uses an appropriate
server or router to enable dynamic assignment of an IP address to a
device connected to the network.
Display Resolution:
Is the number of pixels supported by your TV or VGA
monitor or the output signal of a viewing device, e.g. your NVR. 1920 x
1080 resolution will give you the best display quality.
DNS Server:
Is a standard technology for managing public names of
web sites and other Internet domains. DNS technology allows you to
type names into your web browser which your computer will automati-
cally find the address on the Internet.
DST (Daylight Saving Time):
Is the period of the year when clocks are
moved one hour ahead.
Extranet:
Better known as a remote network. On your NVR, this is where
the DDNS settings are found.
Format:
Is a command that prepares a storage device such as a USB
flash drive or hard drive to hold data.
Firmware:
The software that operates a discrete device (e.g. your
smartphone). It is referred to in this way rather than software as it is

Frame Rate:
The measurement of the rate that pictures are displayed to
create a video feed. The unit of measurement is frames per second (fps).
Gateway:
Is a node or router that routes traffic from a device on your
home network to the outside network that is providing access to the
Internet.
H.264+:
Mass video data requires increased storage capacity. To resolve
this issue, video compression technologies are used to reduce the data
while maintaining image quality. H.264+ is an innovative encoding tech-
nology aimed at surveillance video.
Hardware:
A physical device. Your NVR is hardware.
HDD (Hard Disk Drive):
Is a storage device located inside your NVR. It is
where all data is kept, saved and stored.
HTTP Port:
HTTP stands for Hypertext Transfer Protocol. This port is
used to log into the web browser interface of your NVR using a web cli-
ent, such as Internet Explorer.

from 0.0.0.0 to 255.255.255.255.
IP Channel:
Is a list of cameras that are either directly connected to your
NVR, or connected directly to your network. This will typically display
the camera’s name, IP address, channel number, status, user name and
password.
Live View:
Is the default display mode for your NVR. Each camera con-
nected will be displayed on-screen.
MAC Address:
Is a unique identifier for network hardware. Can also be
used as a super password if you have forgotten your current password.
Main Stream:
Is the video feed that your NVR will display and record.

used to minimise false triggers when your NVR detects motion. Any area
