Advanced Configuration

What You'll Learn in This Guide

Refer to this step when you want to operate multiple cameras together, collaborate with team members in EVA, or build a more sophisticated alert system. EVA's advanced management features allow you to operate efficiently even in large-scale environments.

  • Apply the same detection rules to multiple cameras at once using Scenario Templates

  • Improve visibility in low-light or backlit environments with Brightness Adjustment

  • Receive real-time alerts in external tools like Teams or Slack via Webhook

  • Classify detection scenarios by purpose using Categories

  • Quickly access key cameras using the Camera Favorites feature

  • Deploy large numbers of cameras at once with Bulk Camera Registration

Set Up Scenario Templates

Step Description

Scenario Templates let you save frequently used detection scenarios and reuse them across multiple cameras. Once you've created and validated a scenario, you can quickly apply it when registering new cameras — reducing repetitive setup work and maintaining consistent detection configurations.

  • Use this when
    • You want to set up new cameras quickly
    • You need to apply the same hard-hat violation detection scenario across multiple factory lines
    • You want to deploy the same intrusion detection scenario to multiple building entrances

Brightness Adjustment

Step Description

The Brightness Adjustment feature lets you brighten footage in dark environments or darken it when it's too bright, improving AI detection performance. It is particularly effective in nighttime or backlit conditions.

  • When brightness adjustment is needed
    • Brighten: Low-light environments at night, or underground parking lots and warehouses without natural light
    • Darken: Direct sunlight causing overexposed footage, or backlit environments
    • Default (Auto) mode: Automatically adjusts based on the current camera feed information

    • Immediate response: Receive alerts without continuously watching the EVA screen
    • Record keeping: All alerts are logged in Teams, Slack, etc.
    • Mobile push: Alerts are also pushed to team members' mobile apps
