Summary

Automatic image health check compares a camera’s current image with a stored reference image and flags issues such as moved angle, blocked view, or blur. Use it to proactively detect image problems and fix them before they impact operations.

You can configure Automatic image health check if you are a Super manager or Manager. Engineers cannot edit this feature in Policy Management.

This article explains how to use the Automatic image health check feature in HealthPro.

IMPORTANT: Just like snapshots, Image Health Check generates a reference and current 
image using the MJPEG video profile stored in the camera. Therefore, the feature can 
only be used if an MJPEG profile exists in the camera. However, the order of the 
profiles does not matter. Please ensure that this profile is not deleted.

IMPORTANT: Image health check may not be available when all video profiles of the 
camera are in use by a connected VMS/NVR.

Devices Supported

• Licensed cameras connected via HealthPro Bridge (Hanwha and supported 3rd‑party including AXIS, iPRO, ONVIF).
   
• WAVE/NVR child cameras connected to HealthPro Bridge.
   
• Only the first channel of each camera is used; works independently of Thumbnail ON/OFF.

Not supported in this phase: Direct‑to‑Cloud (D2C) cameras.

Privacy Protection in HealthPro

• No image or video from checks is stored or played in the cloud; HealthPro shows text results only (for example: Tilted, Blocked, Blurred, Glared, Blacked).
   
• On the local HealthPro Bridge database, one reference image and the latest comparison image are stored in encrypted form.

The analysis focuses on scene changes and tries to ignore moving objects to reduce false alarms.

What does Automatic image health check detect?

• Tilted – Camera angle appears changed.
   
• Blocked – View is obstructed.
   
• Blurred – Image is out of focus or very blurry.
   
• Glared – Strong light/reflection degrades visibility.
   
• Blacked – Very dark or frozen‑like scene.

Enabling Automatic Image Health Check

To enable automatic image health check:

1. Sign in to Cloud Portal. 
    
2. Select HealthPro.
    
3. Select Policy Management > Auto image health check (BETA).
   
   
4. Switch Auto image health check to ON.
    
5. Configure Sensitivity, Schedule, Target device management, and (optional) Reminder email, then select Apply.

When first enabled, HealthPro creates a reference image for each selected camera to use for comparison.

Sensitivity Levels

• Low – Detects only large changes.
   
• Medium – Balanced detection.
   
• High – Detects even small changes.

Choose the level that best fits your environment; you can change it anytime.

Automatic Image Health Checks

Scheduling follows the same concept as Auto software update.

• Frequency: Select any day from Sunday to Saturday; multiple selections possible
   
• Start time: Set a start time; subsequent runs reuse this time according to the selected frequency.
   
• Time zone: Runs according to the Organization Location time zone.

Selecting which Cameras are Checked

To select which cameras are checked:

1. Open Target device management within Auto image health check.
    
2. In the Set devices excluded from application menu, set the devices to exclude from updates using filter conditions.
    
3. Click Apply.

NOTE: Unsupported or excluded devices will be automatically excluded when running 
the update.

NOTE: If some devices will not be checked, HealthPro can send a reminder email using 
the existing Remind Me notification setting (same as Auto software updates). Manage 
this in Settings > Notifications.

Viewing Image Health Check Results

• Cameras list (dashboard): Shows problem states when detected.
   
• Camera details page: Shows the current status per camera.

To view and download reference and comparison images:

1. Hover over the result icon on the camera dashboard or device details page to view the reference (REF) image and the compared image side by side. 
    
2. To download both images, click the result icon and they will be saved as a single ZIP file.
   
   Statuses may include Tilted, Blocked, Blurred, Glared, or Blacked. If no issue is detected, the camera is shown as Healthy.

If Automatic image health check and Auto software update overlap, HealthPro saves snapshot and comparison progress, performs updates, then resumes checks from the saved state for affected cameras. This prevents data loss and allows both processes to complete normally.

Privacy-First Image Availability

To protect personal privacy, the ability to preview and download REF and Compared images is governed by your organization's Live Snapshot settings.

• Available when Live Snapshot is enabled.

• Not available when Live Snapshot is disabled or set to Privacy Mode.

Image Health Check results (Good / Warning / Error) are not affected by snapshot settings and remain fully functional regardless.

For more information on snapshot privacy settings, see Camera snapshot options for privacy in HealthPro - Settings: How do I personalize dashboards?

Resetting the Reference Image for a Single Camera

To reset the reference image for a single camera:

1. Open the Camera details page.
    

2. Select Reset REF image from the action menu (⋯). 

   HealthPro captures the current live image as the new reference image (stored locally and encrypted on the Bridge).
    

   NOTE: Alternatively, you can reset REF images in bulk through the REF image 
   menu in Target device management.

   IMPORTANT: Turning Automatic image health check OFF deletes its schedules, 
   target selections, and reference images. Image health information is no 
   longer shown on the camera list or camera details. A warning appears before 
   clearing settings. Turning it ON again requires reconfiguration and new 
   reference images.
