The advanced features available in C-Werk are continuously updated and extended.
C-Werk offers virtually unlimited opportunities for system scaling, task-based customization, and reallocation of resources (based on changes in the number or quality of video and audio monitoring tasks) at end-user sites.
Video surveillance systems based on C-Werk can scale infinitely: there are no restrictions on the number of video servers, workstations or video cameras.
Support for over 1500 models of IP cameras is included, as well as remote access from mobile devices and a web interface. The C-Werk software package supports touchscreens.
Micromodule architecture
The micromodule architecture of C-Werk video management software allows implementing different video management system functions as different operating system processes. Each function is the responsibility of a different micromodule; a dispatcher module monitors the functioning of the micromodules. If a function encounters an error and a process is quit unexpectedly, the dispatcher module automatically relaunches the corresponding micromodule. This does not affect the performance of other processes or the functioning of the VMS overall.
Support for IP cameras
Drivers Pack
IP camera support in C-Werk is provided through the Driver's Pack Module specially developed by Grundig and regularly updated to support new IP devices.
Driver's Pack allows adding support for new IP devices without having to wait for the release of new versions of C-Werk and without reinstalling the entire system.
Multistreaming
Many of today's IP cameras can transmit two video streams with different video parameters and compressed in different codecs. C-Werk supports Multistreaming i.e. receiving two streams from a camera simultaneously: high-quality and low-quality, which allows taking advantage of this feature of IP equipment to optimize the CPU load on the video server and the client workstation. .
GreenStream
The GreenStream feature saves bandwidth and client CPU resources. It automatically chooses a video stream from a camera to the server, and then to the client, depending on the resolution at which the video is currently displayed on the client.
Embedded video camera analytics
C-Werk supports on-board detection embedded in video cameras. This means that when on-board detection tools are triggered, C-Werk is notified and can use these events to drive system reactions. On-board detection does not burden the CPU of the video server and makes use of uncompressed video (completely bypassing the compressing/decompression process), and therefore provide extra stability in difficult conditions such as poor visibility.
360 degree camera support
360 degree camera support allows dewarping video from a fisheye camera or camera with an ImmerVision panomorphic lens to obtain several "normal" flat images with different frame aspect ratios for display on the client screen. One of the resulting virtual cameras can be a virtual PTZ unit.
ONVIF
Grundig is a member of ONVIF (the Open Network Video Interface Forum), which work toward the development and promotion of international standards for network security and video surveillance system interfaces. ONVIF is supported in all versions of Drivers Pack starting with version 3.1.3.
RTSP support
Many IP cameras support multimedia streaming via RTSP. C-Werk supports receiving such streams without requiring integration of the relevant camera via Drivers Pack.
Support for analog cameras in C-Werk
Alongside IP cameras, C-Werk allows you to use analog cameras in your video surveillance system. Analog cameras are more affordable and are well-suited for many installations without high video resolution requirements. In addition, C-Werk allows creating hybrid systems that combine both analog and IP cameras.
Video and Audio Detection Tools
C-Werk video management software incorporates a powerful system for analysis of video images. It includes the following video detection tools:
motion detection;
background change detection;
detection for loss of video quality;
abandoned objects detection;
detection of crossing a line in a given direction;
motion start detection;
motion stop detection;
loitering detection;
object appearance detection;
object disappearance detection
In addition to the video detection tools, C-Werk has two audio detectors:
noise detection - is triggered by exceeding a certain threshold volume level;
silence detection - is triggered when the microphone signal disappears completely
Macros can be set to automatically run when a detection tool is triggered (on a per-detector basis). Multiple detection tools can be combined into complex conditional rules.
Video archive
SolidStore
SolidStore is a new file system for reliable video storage developed by Grundig especially for storing video archives. By optimizing the reading/writing process we managed to achieve three important advantages:
Enable high read/write speeds, approaching the physical access speed limit of the hard disk.
Increase the service life of the hard disk.
Solve the problem of data fragmentation.
TimeCompressor
Time Compressor allows the user to set a time range for video footage and get a short video clip of all moving objects in the scene. Objects and events captured at different times are displayed simultaneously in a condensed "video synopsis". Time Compressor is especially convenient for viewing large archives that feature a relatively small number of active objects.
Forensic Search in Archive
The C-Werk video management software (VMS) utilizes VMDA – a database developed by Grundig for indexing and storing descriptions of observed scenes. Along with video recording, this database allows archiving characteristics of all moving objects in the scene, and then uses these characteristics to perform quick searches of the video recordings (MomentQuest2 technology).
Interactive 3D Map
Interactive 3D Map superimposes camera locations on a site map and displays camera views in the same window. Cameras in the current layout are color-coded by current status. Operators can instantly pinpoint where a selected camera is located on the map and identify the corresponding location of interest.
Immersion Mode
When enabled, this mode overlays a translucent video viewing tile on the map; fixed objects in the field of view (furniture, doors, etc.) are combined with their depictions on the map. This allows easily seeing where a person or car is located and where it is going.
OpenStreetMap
OpenStreetMap support is available in C-Werk. The site map is downloaded from the Internet and the user selects the necessary area and scale. Additional map data is downloaded in real time, if needed, when zooming in/out or scrolling.
Note
To work with OpenStreetMap maps in C-Werk, you need to purchase an OpenStreetMap license.
Virtual PTZ cameras on the map
The Virtual PTZ Camera function becomes available when the map contains at least one fisheye camera. This function allows viewing video from a fisheye camera directly on the map. Click anywhere in the fisheye video shown in a layout cell to dewarp the source video, with digital zoom and click-to-focus.
User Interface
Editable camera layouts
C-Werk allows you to create custom camera layouts. Layouts can be configured in any way the user wants and the aspect ratios of viewing tiles can be fine-tuned. Editable layouts efficiently fit different cameras with different aspect ratios on the same screen, as well as support display of dewarped fisheye camera footage.
Autozoom
Autozoom helps to monitor moving objects by automatically adjusting the level of digital zoom. Autozoom shows close-in video for parts of the frame that contain a moving object or objects and follows them as they move, just as a movie camera does when taking a close-up shot.
Face Recognition
C-Werk includes an algorithm for recognizing human faces in a video frame and subsequent search for them in a video archive of several cameras. You can search by an uploaded photo or by an image of a person's face selected in a video archive frame. The system will return the video fragments from the archive where the searched person is present as search results.
NumberPlate Recognition
C-Werk also includes an algorithm for recognizing vehicle number plates. The recognized number plates are saved to a database and matched with a video archive of several cameras. If a number plate contains similar characters, the system generates several hypotheses during the recognition. This increases the probability of a successful search for a particular number in a generated database.
Receiving Events from External Systems
C-Werk includes a new feature set that is capable of receiving events from various external devices and systems — POS terminals, access control units, external software, etc.
