Pre-alarm images is a feature available for
selected cameras only. It enables the sending
of images from immediately before an event
took place from the camera to XProtect
Essential via e-mail.
Pre-buffer
See the description of Pre-recording.
Pre-recording
The ability to store recordings from periods
preceding detected motion and/or specified
events. Based on incoming video being
buffered on the XProtect Essential server in
case it is going to be needed for a motion- or
event-triggered recording. Using pre-recording
can be highly advantageous: if, for example,
you have defined that video should be
recorded when a door is opened, being able to
see what happened immediately prior to the
door being opened may also be important.
Privacy masking
The ability to define if and how selected areas
of a camera's view should be masked before
distribution. For example, if an XProtect
Essential camera films a street, you can mask
certain areas of a building (for example,
windows and doors) with privacy masking in
order to protect residents' privacy.
PTZ
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
Essential, 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.
