The Video Management Software (VMS) is a component of a security camera system that in general:
- Collects video from cameras and other sources
- Records and stores collected video to a storage device
- Provides an interface to both view the live video and access recorded video
Many modern network cameras offer internal capabilities to record and review video directly themselves via a web browser and without the use o a VMS. However a camera’s built-in web interface is typically exclusive to the camera itself and does not normally provide a shared access capability across other network cameras.
VMSes offer a number of capabilities in what has to do with the management of the received video feeds. These capabilities a configured according to each customer needs. The main characteristics of the proposed VMS by EPI Systems SA are the following:
Valerus is the Video Management Software of Vicon. It is designed and built on the open standards of the industry as they are defined by ONVIFTM, an industry common protocol adopted by most camera and VMS systems. By adopting ONVIFTM Valerus offers the ability to integrate on it third party solutions that support said standard.
The full Valerus VMS system is composed by the following elements:
- The application/ Web Server: This is the center of the system where the database is active and all the system programming is stored. On the server also connect the web clients that manage the system. On systems with less than 150 cameras this can be used as an all-in-one server, a recording server as well as the application server.
- Recording Servers: All recording servers (Network Video Recorders, NVR) record and provide video and audio streams. Each is capable of handling a specific number of cameras based on its specifications.
- Client Viewing Station: With this thin-client topology, client viewing stations can be on any PC running Microsoft Internet Explorer 11 and above or Firefox.
Valerus main Characteristics
Valerus VMS boasts a great number of characteristics as:
► Dashboard through which statistical data are provided for every camera and NVR on the network in order to be able to evaluate the behavior of the system and to diagnose problems
► Rules, Events and Alarms: Through Valerus the administrator can set rules that will cause the system to react on defined events. The reaction is known as an alarm. When an event, for which a rule has been defined, occurs then an alarm will be triggered on Valerus. A dedicated alarm event tab will open to display the content configured for the alarm. There will also be a visual and audible indication of the alarm, which can be set on/off by the user, configured to time out or require a manual shut off. Except the alarms through the Valerus system, an email server can be connected to allow sending email alerts.
► Recording: With Valerus both video and audio can be recorded and played back. Additionally, audio can be associated and linked to video that is recorded. Recording can be scheduled and pre-event recording is provided.
► Export: Video clips can be exported and saved to any storage media. The video can be archived in MP4 format. Video clips are authenticated in the Valerus player.
► Masking: Privacy masks can be setup in the VMS when it is necessary to protect sensitive areas of the video from being seen. A VMS-based unmask feature is also provided to temporarily remove the mask on the video display. The mask can also be removed on an exported video clip.
► Museum Search: The museum search feature allows a very fast and accurate scanning of the recorded video for changes in a specific area of interest, such as motion in an area or a missing item.
► Thumbnail Search: Through thumbnail search the user sees thumbnails from the video for the chosen period. By choosing 2 thumbnails the system shows new thumbnails from the scenes of the video between the chosen thumbnails. With this method of searching the user can find the piece of video he needs.
► Valerus Events Framework (VEF): An add-on to Valerus that allows it to integrate external partners’ systems such as facial recognition systems, license plate readers, ATMs and many others and bring their event data to the VMS as video feed that can be viewed as any other resource. Using the Events Framework allows capturing, storing and searching the events database to match the event with a related camera for visual confirmation. This is also included in the search function when active. This gives the ability to search a video in relation to an incident (e.g. a certain license plate is appearing on the video).
►360o Lens Dewarp: This capability allows digitally manipulating the full fisheye image of a 360o lens camera and zooming into specific areas on live and recorded video
► Smart Analytics: Integrated server-based Smart Analytics offer real-time analytics. With smart analytics the surveillance system becomes more effective as the cameras become “smarter” with the help of Valerus. Smart Analytics is an application suite that consists of SmartAction, SmartSearch and BusinessIntelligence. SmartAction uses predefined rules of behavior that control the activity over hundreds of video feeds and provides alarms and reactions of the system only if certain behaviors occur. SmartSearch searces on multiple channels of recorded video for certain events or objects of interes. BusinessIntelligence extracts statistical information regarding traffic volumes, traffic trends and motion patterns from surveillance videos. Equipped with such information, facility managers, marketing leaders and business owners can make educated decisions regarding various operational and resource allocation aspects at their facility. Valerus Smart Analytics can analyze video from multiple sources at parallel and allow the detection of complex scenarios that connect search rules from different cameras. The combination of rules that can be applied to every camera is limitless.
► Support for H.265 Compression: Now supported by ONVIF, H.265 format offers higher video compression to support lower bandwidth and overall storage requirements.
