How to Configure Active Defense in VIGI NVR

Active Defense is a proactive security feature in IP cameras that uses AI detection to identify threats—such as intrusion or loitering—and instantly triggers deterrents like flashing lights, voice warnings, or sirens. It helps prevent incidents in real time, reducing risks before they escalate. This article introduces how to configure Active Defense on VIGI NVR. Be aware that at least one VIGI IPC is needed, since NVR itself cannot accomplish active defense on its own.

What Is Active Defense?

Active Defense is a proactive security feature available on compatible VIGI IP cameras. It uses AI-based detection to identify threats — such as intrusion or loitering — and immediately triggers deterrents including flashing lights, voice warnings, or sirens. The goal is to stop incidents before they escalate rather than simply recording them after the fact.

Important

The VIGI NVR cannot perform Active Defense on its own. At least one compatible VIGI IPC (IP camera) must be connected and configured — the camera is what detects threats and triggers the deterrents.

Requirements

  • VIGI NVR Must be a model that supports Active Defense. Check your NVR's firmware and datasheet on the product support page to confirm compatibility.
  • VIGI IPC (camera) At least one connected VIGI IP camera that supports Active Defense. The camera handles AI detection and triggers the physical deterrents.
Note

Recent firmware updates may have expanded Active Defense support to additional models. Visit your product's support page and check the firmware section for the latest improvements.

Configuration via Web Interface

Active Defense can be enabled and configured directly through the NVR's web management interface. Follow the steps below.

  1. 1
    Enable Active Defense. Go to Settings > Event > Active Defense and toggle the arm status on for the desired channel. Active Defense toggle in the NVR web interface
  2. 2
    (Optional) Configure detailed settings. Click the gear icon next to the channel to open advanced options. Here you can select the alarm type (e.g. flashing light, voice warning, siren) and set a timetable to control when Active Defense is active.

Configuration via VMS

Active Defense can also be configured through VIGI's Video Management Software (VMS) for users managing cameras centrally from a PC.

  1. 1
    Enable Active Defense. Log into VMS and go to Settings > Event > Active Defense. Toggle the arm status on for the desired channel. Active Defense toggle in VIGI VMS
  2. 2
    (Optional) Configure detailed settings. Click the gear icon to access advanced options. Select the alarm type and configure a timetable to schedule when Active Defense runs. Detailed Active Defense configuration options in VMS
Tip

Both configuration methods — web interface and VMS — offer the same options. Use the web interface for quick access to a single NVR, or VMS if you are managing multiple cameras and recorders from one place.
