Advanced Configuration

What You'll Learn in This Guide

Go beyond basic setup and master EVA’s advanced tools to create a sophisticated, efficient detection system.

  • Apply the same detection rules to multiple cameras using Common Scenarios

  • Improve custom object detection accuracy with Image Guided Detection

  • Focus monitoring on specific zones using Detection Areas

  • Enhance low-light or backlit performance with Brightness Adjustment

  • Receive real-time alerts in external tools via Webhook integration

1

Set Up Common Scenarios

Step Description

Common Scenarios are reusable detection rules that can be applied across multiple cameras. Create once, deploy everywhere — drastically reducing repetitive work.

  • Typical Use Cases
    • Apply the same safety rules across all factory zones (e.g., “hard hat required”)
    • Enforce identical access control at every entrance
    • Detect illegal parking across an entire parking lot

Common Scenario Management Page

Actions

  1. Go to Settings
    • Click “Settings” in the top navigation → “Common Scenario”
  2. Enter Common Scenario management
    • Existing scenarios appear in the list
    • Edit an existing one or click “+ New Scenario”
  3. Write the scenario prompt
    • Describe the universal rule (e.g., “Alert me if a worker enters a zone without a hard hat”)
    • Avoid camera-specific details
  4. Generate the Enriched Prompt
    • Click “Generate” → review the structured prompt and targets
  5. Review & refine
    • Edit Detection Steps or Exceptions if needed
  6. Save
    • Click “Save” to store the Common Scenario
  7. Apply to cameras
    • New cameras: Select it during registration
    • Existing cameras: Choose it when editing the camera

Image Guided Detection

Step Description

Image Guided Detection lets EVA detect completely new or custom objects that were not part of its original training — just provide a few reference images.

  • Best for
    • Company-specific safety gear, tools, or signs
    • Unique products or parts on a production line
    • Site-specific equipment or barriers

Image Guided Detection Setup

Actions

  1. Open Detail & Settings
    • On the camera detail page → Detection section → “Detail & Settings”
  2. Add a new custom target
    • e.g., “company_helmet”
  3. Pause video when the object is clearly visible
  4. Draw a bounding box around the object
  5. Click “Add Reference”
  6. (Optional) Add more reference images from different angles/lighting
  7. (Optional) Adjust Detection Sensitivity for this target
  8. Click “Submit” → EVA now detects your custom object

Set Detection Areas (Zones)

Step Description

Limit monitoring to specific regions of the video feed. Alerts are only sent when detections occur inside your defined zones — reducing noise and focusing on what matters.

  • Great for
    • Hazardous zones in factories
    • Specific entrances or corridors
    • Fire lanes or restricted parking spots
    • Critical inventory areas

Actions

  1. Open Detail & Settings
  2. Go to Custom Scenario tab → click “Area”
  3. Name the zone
    • e.g., “High-Risk Zone”, “No-Entry Area”
  4. Click “Capture” → draw a box on the live/preview image
  5. Click “Submit”
  6. Verify: A yellow box with the zone name appears on the live feed
4

Brightness Adjustment

Step Description

Improve detection in dark or overly bright environments by dynamically adjusting image brightness. Especially useful at night or in backlit conditions.

  • When to use
    • Brighten: Nighttime, underground parking, warehouses
    • Darken: Direct sunlight, strong backlighting
    • Range: -100 (very dark) to +100 (very bright)
Brightness Adjustment Result
Brightness Adjustment Result

Actions

  1. Choose a value (-100 to +100)
    • Positive = brighter (e.g., +50)
    • Negative = darker (e.g., -30)
  2. Type the command in the Commands panel
    • Format: set brightness level [number]
    • Examples:
      set brightness level 50
      set brightness level -30
  3. Press Enter → adjustment applies instantly
    • “Brightness adjustment active” appears top-left of the video
5

Receive Alerts via Webhook

Step Description

Connect EVA to Microsoft Teams, Slack, or any tool that supports webhooks to get real-time alerts outside the EVA interface.

  • Benefits
    • Instant team notifications
    • No need to watch EVA constantly
    • Full alert history in your chat tool
    • Mobile push notifications
Microsoft Teams Webhook Alert
Microsoft Teams Webhook Alert

Actions

  1. Create a Webhook URL in Microsoft Teams
  2. Open Webhook settings in EVA
    • On the camera monitoring page → click the swirl icon in the top bar
  3. Enter webhook details
    • Name: e.g., “Safety Team Channel”
    • URL: Paste the Teams webhook URL
  4. Save
  5. Test: Future detections will instantly appear in Teams with time, camera info, and image
