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 camera’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 camera’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.
