Glossary of Terms

Pan-tilt-zoom. A highly movable and flexible

type of camera.

PUK

Personal Unblocking Key or PIN Unlock Key—

number used as an extra security measure for

SIM cards.

R

Recording

On IP video surveillance systems, recording

means saving video and, if applicable,

audio from a camera in the cameraâ€™s

database on the surveillance system. In

many IP surveillance systems, all the

video/audio received from cameras is not

necessarily saved. Saving of video and audio

in a cameraâ€™s database is in many cases

started only when there is a reason to do so,

for example, when motion is detected, when

an event occurs, or when a specific period of

time begins. Recording is then stopped after a

specified amount of time, for example, when

motion is no longer detected, when an event

occurs, or when a time period ends. The term

recording originates from the analog video

era, when images were taped only when the

record button was pressed.

Recording Server service

Windows service (without any user interface)

used by your system for recording and

displaying video. Video is only transferred to

the surveillance system while the Recording

Server service is running.

Restore point

Restore points allow you to return to a

previous configuration state. When a

configuration change is applied in XProtect

Professional, a restore point is created. If

something goes wrong in your configuration,

you can browse through restore points, and

return to a suitable one.

S

SCS

A file extension (.scs) for a script type targeted

at controlling clients.

SDK

Software Development Kit—programming

package enabling software developers to

create applications for use with a specific

platform.

SIM

Subscriber identity module—circuit stored on a

small card inserted into a mobile phone or

computer, or other mobile device. The SIM

card is used to identify and authenticate the

user.

SLC

Software license code—product registration

code required for using the XProtect

Professional software. If you do not have

system administration responsibilities, you do

not have to deal with SLCs. System

administrators use SLCs when installing and

registering the software.

SMTP

Simple Mail Transfer Protocol—standard for

sending e-mail messages between mail

servers.

Subnet

A part of a network. Dividing a network into

subnets can be advantageous for

management and security reasons, and may in

some cases also help improve performance.

On TCP/IP-based networks, a subnet is

basically a part of a network on which all

devices share the same prefix in their IP

addresses, for example 123.123.123.xxx,

where the first three numbers (123.123.123)

are the shared prefix. Network administrators

use subnet masks to divide networks into

subnets.
