Glossary

AP Mode
- This mode allows wireless communication with the provided
cameras, however your NVR must be physically connected to your rout-
er to gain Internet access.
Auto DNS (Domain Name System)
and translates them into Internet protocol addresses. For example,
www.google.com will have a DNS server address that is equivalent to
74.125.224.72. For this option, the DNS server is automatically provided
by your Internet service provider.
Bitrate
- The amount of data that your NVR will use to record video.
The higher the bitrate, the more space each recording will consume on
the hard drive. Increasing this will also consume more bandwidth when
streaming.
DHCP (Dynamic Host Configuration Protocol)
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 HDTV or
VGA monitor. 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 is the period of the year when clocks are moved
one hour ahead.
Format
- Is a command that prepares a storage device such as a USB
flash drive or hard drive to hold data.
Frame Rate
- The measurement of the rate that pictures are displayed
to create a video feed. This is typically done as frames per second.
- A service that stores domain names
- Uses an appropriate
HTTP Port
- It stands for Hypertext Transfer Protocol and is the port that
is used to log into your NVR.
IP Address - The address of a device attached to the network. Each de-
vice on the network must use a unique address. IP addresses range
from 0.0.0.0 to 255.255.255.255.
Main Stream
- Is the video feed that your NVR will display and record.
Motion Detection
- Is the main method used by your NVR to detect mo-
tion and is an essential part of your security system. It does this by com-
paring one frame of video with the next. A certain amount of difference
between these two frames is interpreted as motion.
NTP - It stands for Network Time Protocol and is used to synchronize
your NVR's clock with a time based server.
NTSC
- Is the video system used in North America, Canada and some
Latin American countries. In NTSC, 30 frames are transmitted each
second.
OSD (On-screen Display)
- Display information from the camera such
as time, date and camera name on-screen.
PAL - Is the video system used in the United Kingdom, Australia and
most European countries. In PAL, 25 frames are transmitted each sec-
ond.
Resolution
- The measure of detail that can be seen in an image. The
higher the number, the greater the detail available.
Server Port
- Is a logical connection place and specifically, using the
Internet protocol TCP/IP, the way a client program specifies a particular
server program on a computer in a network. Your NVR will use this port
to send information through.
