Advanced Event Management

When it comes to a critical event having a smart and responsive event management in place is essential for video surveillance system. The VioStor NVR offers advanced event management function polished with intuitive AJAX Web interface. The VioStor NVR is equipped with enterprise-level alarm-triggering mechanism and supports various alerts and abnormal event. This feature greatly strengthens the security, management efficiency, and compatibility of the VioStor NVR systems.

When a moving object is detected by IP camera 1, the NVR triggers the alarm sensor connected to IP camera 1, adjusts the monitoring angle of IP camera 2 to the specified preset position, enables alarm recording on both cameras, and delivers email and SMS alert instantly to the administrator.

Advanced event management can be divided into two parts:

  • Events
    Supports more event types, e.g. motion detection, alarm input, connection failure, recording failure, and user-defined event to trigger follow-up actions.
  • Actions
    More actions can be activated when an event is triggered, such as multi-channel recording, adjusting the PTZ camera to the preset position, alarm output, built-in buzzer, email & SMS alert, and user-defined action.

Events Overview

Camera Events
