How to Configure Active Defense in VIGI NVR

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.

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.

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.
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.
