Smart VCA Event Search

The NVRs support alarm management and event search of VIVOTEK’s deep-learning video analytics technology, Smart VCA. VCA rules and information such as people-tracking frames and motion-detection frames can be shown on live or playback video display. The user can search by single or multiple event types, playback triggered events and then export these search results to video clips.



Cybersecurity Management Solution

Integrate cybersecurity attack events from VIVOTEK cameras and NVR to VAST 2 alarm management. In addition to alarm action and notification, VAST 2 becomes the central management site to recognize attack trends and status, as well as acquire attack information.



Data Magnet

Data Magnet offers the capability to integrate third-party data source into VAST 2, which provides quick access to data along with video. This supports simultaneous display with live event monitoring. All events will be stored for later searches.


2.5D Visualization eMap

Multiple layers and camera FOV views allow users to instantly pinpoint a selected camera and the location on the map.



Evidence Lock & Export

Manually extend the retention time for video recordings and manage a high number of investigation scenarios. Easily export multiple video recordings with custom layouts in a specific time period or instant snapshot with a fast click.



License Plate Recognition Solution

VAST 2 can link license plate information with live streaming and recordings via integration with VIVOTEK’s License Plate Recognition cameras (such as IB9385-LPR and IB9387-LPR). Users can search and analyze historical data and display the number of recognized license plates data in line graphs, export search results or display live streaming video data from alarm event-triggering cameras when license plate information matches preset alarm criteria.
