The Archiver role is responsible for the discovery, status polling, and control of video units. The Archiver also manages the video archive and performs motion detection if it is not done on the unit itself.
The Auxiliary Archiver role supplements the video archive produced by the Archiver role. Unlike the Archiver role, the Auxiliary Archiver role is not bound to any particular discovery port, therefore, it can archive any camera in the system, including cameras federated from other Security Center systems. The Auxiliary Archiver role cannot operate independently; it requires the Archiver role to communicate with video units.
In KiwiVision™ Video Analytics, the background is composed of the static environment and immovable objects that are learned to identify changes in an image.
In KiwiVision™ Video Analytics, a block is a rectangular section of the camera image where image processing, such as pixelation, is performed.
The Camera events task is an investigation task that reports on events pertaining to selected cameras within a specified time range.
Camera Integrity Monitor
The Camera Integrity Monitor role samples video images from cameras at regular intervals, detects abnormal variations that indicate that cameras might have been tampered with, and generates Camera tampering events.
camera integrity monitoring
In Security Center, camera integrity monitoring is software that detects any form of tampering with the camera, such as moving the camera, obstructing the camera view, changing the camera focus, and so on. The software automatically generates events to alert the security team to remedy the situation.
A compression artifact is a type of error, or deviation from the original recording, that can be detected in images, audio, and video after applying a lossy compression algorithm. The severity of these errors can vary depending on the compression being used.
A digital signature is cryptographic metadata added to video frames by the Archiver or Auxiliary Archiver to ensure their authenticity. If a video sequence is manipulated by adding, deleting, or modifying frames, the signature of the modified content will differ from the original, indicating that the video sequence has been tampered with.
In KiwiVision™ Video Analytics, the image foreground is composed of people and mobile objects. These dynamic elements are identified by comparing the input image to the learned background to identify changes in an image.
Intrusion detection designates one of the following: intrusion detection (hardware) or intrusion detection (analytics).
intrusion detection (analytics)
In KiwiVision™ video analytics, intrusion detection refers to the software technology that is used to automatically detect the intrusion of people, objects, or vehicles into protected or private areas when analyzing a video sequence.
intrusion detection (hardware)
In Security Center, intrusion detection refers to the detection of an intrusion into a secured area by an intrusion detection unit (hardware device).
The KiwiVision™ Analyzer role performs video analytics processing for assigned cameras.
KiwiVision™ Camera Integrity Monitor
KiwiVision™ Camera Integrity Monitor is a Security Center module that ensures cameras are operational at all times by performing regular checks of their video to detect whether the cameras have been tampered with.
KiwiVision™ intrusion detector
(Obsolete) The KiwiVision™ intrusion detector task is an investigation task in Security Desk that is used to generate software intrusion detection reports. Starting in KiwiVision™ video analytics 4.1 GA, this task is replaced by the Security video analytics task.
The KiwiVision™ Manager role manages and distributes the video analytics requests to the available KiwiVision™ Analyzer roles, stores the events generated by these Analyzer roles, and handles the report requests sent from Security Desk.
KiwiVision™ People Counter
The KiwiVision™ People Counter module is part of the KiwiVision™ video analytics plugin, and adds analytics capabilities for people counting to Security Center.
In KiwiVision™ Video Analytics, pixelation is an anonymization method that uses groups of pixels, called blocks, to obscure all or part of an image.
KiwiVision™ Privacy Protector™
KiwiVision™ Privacy Protector™ is a Security Center module that ensures the privacy of individuals recorded by video surveillance cameras while safeguarding potential evidence.
KiwiVision™ Security video analytics
The KiwiVision™ Security video analytics module is part of the KiwiVision™ video analytics plugin, and adds analytics capabilities for security monitoring to Security Center.
KiwiVision™ video analytics
The KiwiVision™ video analytics plugin adds automation to security monitoring and people counting tasks through the KiwiVision™ Security video analytics and KiwiVision™ People Counter modules.
people counting (analytics)
In KiwiVision™ video analytics, people counting refers to the software technology that is used to detect the number of people in an area, and entering or exiting an area.
In Security Center, privacy protection is software that anonymizes or masks parts of a video stream where movement is detected. The identity of individuals or moving objects is protected, without obscuring movements and actions or preventing monitoring.
The Privacy Protector™ role requests original video streams from Archiver roles and applies data anonymization to the original video streams. The privacy-protected (anonymized) video stream is then sent back to the Archiver role for recording.
A public task is a saved task that can be shared and reused among multiple Security Center users.
Restricted Security Area Surveillance
The Restricted Security Area Surveillance (RSA Surveillance) plugin integrates tracking systems into Security Center. A tracking system might use radars, lasers, heat sensors, and cameras to detect activity in restricted areas and on the perimeter of a property.
Restricted Security Area Surveillance (RSA Surveillance)
A scheduled task is an entity that defines an action that executes automatically on a specific date and time, or according to a recurring schedule.
Security video analytics
The Security video analytics task is an investigation task that reports on video analytics events that are triggered based on analytics scenarios.
In KiwiVision™ video analytics, tailgating occurs when a person enters an area behind another person within a defined time frame.
Video analytics is the software technology that is used to analyze video for specific information about its content. Examples of video analytics include counting the number of people crossing a line, detection of unattended objects, or the direction of people walking or running.
video analytics scenario
A video analytics scenario is an analytics configuration that is applied to video streams and that defines what information in the video is analyzed.
A video stream is an entity representing a specific video quality configuration (data format, image resolution, bit rate, frame rate, and so on) on a camera.
