Input: 1. a physical device intended for receiving information on the status of an object; 2. a system object that displays the properties of an installed Input.
Scene Analytics detection tool – a detection tool used to analyze the situation in a camera's field of view according to set criteria.
Audio signal detection – a detection tool is triggered by an increase in the signal/noise ratio above a set level.
Loss of quality detection – a detection tool is triggered by a loss of quality in the video image from a camera.
Position change detection – a detection tool is triggered by a substantial change in the background of a video image indicating a change in the position of the camera in space.
Object disappearance detection – a detection tool is triggered by the disappearance of an object in a set area of a video camera's field of view.
Abandoned object detection – a detection tool is triggered when an object remains motionless in a detection zone for a prolonged period.
No Signal detection – a detection tool is triggered by the absence of an audio signal from an audio device.
Line Crossing detection – a detection tool is triggered when the trajectory of an object crosses a virtual line in a video camera's field of view.
Object appearance detection – a detection tool is triggered by the appearance of an object in a set area of a video camera's field of view.
Stopping detection – a detection tool is triggered by the cessation of motion in a set area of a video camera's field of view.
Noise detection – a detection tool is triggered by an decrease in the signal/noise ratio below a set level.
Domain – a selected group of computers on which the server configuration of the C-Werk software package is installed. Linking the servers in a group makes it possible to set up interaction between them, thus organizing a distributed system.
Detection zone – the area of a video image processed by a detection tool is triggered.
Interface cable – cable used to connect two or more devices together for data transfer.
Interface object – a system object used for interaction between the user and software (data input/output).
Client – designation for a personal computer on which C-Werk software is installed (or will be installed) as a Client. Designation for the graphical shell of the C-Werk software package.
Slideshow – automatic switching of user layouts, or of viewing tiles in a single layout if working with standard layouts.
Licensing – regulating and setting the terms for usage of Grundig software modules.
Detection zone: 1. the area of a video image processed by a detection tool is triggered; 2. a tool which allows the user to mark out an area of the video image which is not to be processed by a detection tool is triggered.
Microphone: 1. a source of audio signals; 2. a system object used to manage the parameters of audio signal reception.
Video surveillance monitor – an interface object used to manage the user interfaces of the C-Werk software, e.g., layouts, viewing tiles, various panels and context menus, etc.
Viewing tile – interface object displaying the video stream coming from a certain video camera and enabling control of that video camera.
Dial panel – panel (part of the PTZ control panel) used to dial a preset.
Archive navigation panel – all interface objects used to work with an archive, e.g., timeline, list of alarm events, etc.
Control panel – panel made up of tabs accessible to the user, used to navigate from one group of interface objects to another.
Playback control panel – panel containing buttons to control playback of video recordings: Play, Pause, Go to next video recording, etc.
PTZ control panel – all interface objects used to control a certain PTZ device.
Layout control ribbon – panel containing tools to create, edit, and manage layouts.
PTZ device – a system object displaying the properties of an installed PTZ camera device.
Note
Also used to designate a physical device
The PTZ subsystem encompasses all the tools that provide for remote control of a PTZ device and the lens of a video camera.
