Glossary
Motion Detection:
Is the main method used by your DVR or NVR to detect
motion 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 be-
tween these two frames is interpreted as motion.
NAS (Network Attached Storage):
that other network devices can use as if the storage was connected directly.
NIC (Network Interface Controller):
device to connect to a network. Both wired and wireless NICs exist for these
respective purposes.
NTP (Network Time Protocol):
clock automatically with a network time server. Most time servers are on the
internet.
NTSC: Is the video system used in North America, Canada and some Latin
American countries. In NTSC, 30 frames are transmitted each second.
Optical Zoom:
Is a true zoom feature. It allows you to zoom in (or out) on an
object to get a closer view by using the camera's lens.
OSD (On-screen Display):
Display information from the camera such as time,
date and camera name on-screen.
Overscan: Is mainly used on older television sets to display the entire view-
able area correctly on-screen. It does this by cutting off the edges of the pic-
ture. This is not required for modern Plasma and LCD TVs as the image is
digitally processed to display the correct aspect ratio.
Pack Duration:
Instructs your DVR or NVR to split recordings into discrete
units. Each unit can be a maximum of 60 minutes in length. Your DVR or NVR
will play these as one continual video.
PAL: Is the video system used in the United Kingdom, Australia and most
European countries. In PAL, 25 frames are transmitted each second.
