Milestone Basis+ 6.5 - Manual (Page 149)

Milestone XProtect Basis+ 6.5; Administrator’s Manual
M
MAC Address: Media Access Control address, a 12-character hexadecimal number uniquely
identifying each device on a network.
Monitor: An application used in previous versions of XProtect Basis+ for recording and displaying
video. The Monitor application has from XProtect Basis+ version 6.5 been superseded by the
Milestone Recording Server Service.
MPEG: A group of compression standards and file formats for digital video developed by the
Moving Pictures Experts Group (MPEG). MPEG standards use so-called lossy compression as they
store only the changes between frames, removing often considerable amounts of redundant
information: Keyframes stored at specified intervals record the entire view of the camera, whereas
the following frames record only pixels that change. This helps greatly reduce the size of MPEG
files.
N
NTLM: Abbreviation of Windows NT LAN Manager; a network authentification protocol.
P
Patrolling: The movement of a PTZ camera between two or more preset positions.
PIN: Personal Identity Number (or Personal Identification Number), a number used to identify and
authenticate users.
Polling: Regularly checking the state of something, for example whether input has been received
on a particular input port of a device. The defined interval between such state checks is often called
a polling frequency.
PTZ: Pan/Tilt/Zoom; a highly movable and flexible type of camera.
PUK: Personal Unblocking Key, or PIN Unlock Key, a number used as an extra security measure for
SIM cards.
R
Recording: In IP video surveillance systems, the term 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 of 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, when motion is no longer
detected, when an event occurs, when a time period ends, or similar. The term recording originates
from the analog world, where video/audio was not taped until the record button was pressed.
Recording Server Service: A vital part of XProtect Basis+; recordings are only transferred to the
surveillance system while the Recording Server service is running.
Remote Client: Client application for letting remote users access the surveillance system in order
to view live video, play back recorded video, activate outputs, print and export evidence, etc.
(access to features depend on individual user rights). Users access the Remote Client straight from
the surveillance system server through an Internet Explorer browser.
S
SDK: Software Development Kit; a programming package enabling software developers to create
applications for use with a specific platform.
SIM: Subscriber Identity Module, a small card inserted into a GSM mobile phone, a GSM modem,
etc. The SIM card is used to identify and authenticate the user.
