Alibi AI Powered NVR Dallas. Face comparison on the Alibi Vigilant AI-powered NVR lets you go from “hours of footage” to “instant matches” by automatically comparing captured faces against stored reference images. This turns your NVR from a basic recorder into an active investigative and monitoring tool that can speed up incident response and improve overall situational awareness.
What Does the Face Comparison Feature Actually Do?
Face comparison uses the Vigilant NVR’s built-in AI to detect faces in video streams, extract facial data, and compare those data points against faces already stored in your system.
With the feature properly configured, you can:
- Search recorded footage for specific individuals using a reference face.
- Get quick, filtered match results instead of manually scanning video.
- Export relevant clips for evidence, reporting, or sharing.
This is especially valuable for:
- Identifying repeat trespassers or known offenders.
- Verifying presence during specific timeframes.
- Supporting investigations after an incident.
How Do You Put the NVR in the Right Mode for Face Recognition?
Before you can use face comparison, your NVR must be in a mode that supports AI-based face recognition.
Step 1: Verify the NVR mode
From the NVR interface:
- Access the system mode or AI configuration section.
- Confirm that the NVR is set to a mode that enables face recognition/face comparison capabilities (as shown in the video’s initial steps).
If the unit is in a basic recording-only mode, face features will be limited or unavailable. Switching to an AI-enabled mode allows the NVR to start analyzing video for faces.
Step 2: Confirm camera compatibility
Face comparison works best with cameras that:
- Provide a clear view of faces (proper angle, distance, and lighting).
- Are correctly added and online within the Vigilant NVR.
Take a moment to ensure your key entry, lobby, or choke-point cameras are optimally positioned for face capture.
How Do You Enable the Face Comparison Function?
Once the NVR is in the correct mode, you need to turn on face comparison in the AI settings.
Step 3: Enable face comparison in the menu
According to the video’s early configuration segment, you will:
- Navigate to the AI or VCA (Video Content Analytics) section.
- Locate the Face Comparison or Face Recognition option.
- Enable the feature and apply/save your changes.
This instructs the NVR to begin detecting and processing faces from the video stream rather than simply recording raw footage.
Step 4: Verify that face data are being captured
After enabling, use live view or logs to confirm:
- Face icons or overlays appear when people pass in front of the camera (depending on your overlay settings).
- The system is populating face snapshots or face events in the AI/VCA database section.
If nothing appears, re-check that:
- Cameras are assigned to the correct AI channels.
- Lighting and camera angles allow the system to see faces clearly.
How Do You Set Up Monitoring Tasks for Face Comparison?
Monitoring tasks tell the NVR where, when, and how to watch for faces.
Step 5: Configure monitoring tasks
In the face comparison or AI menu, the video walks through:
- Choosing which channels/cameras to monitor for face events.
- Setting time periods (for example, 24/7, business hours, or specific shifts).
- Selecting the comparison mode (e.g., comparing against a particular face library or list).
These tasks let you tailor face comparison to:
- High-risk doors and sensitive areas.
- Critical time windows when incidents are more likely.
Step 6: Associate tasks with face libraries (if applicable)
Some deployments may use:
- A watchlist of banned individuals or persons of interest.
- An authorized list for verification.
Assigning the appropriate list to each monitoring task ensures the system compares captured faces against the right reference set.
How Do You Use VCA Search for Face Matching?
VCA (Video Content Analytics) Search is where you actively look for matches in recorded footage.
Step 7: Open VCA Search
From the main menu:
- Go to VCA Search or an equivalent “AI search” section.
- Select Face Match or Face Comparison as the search type.
You will see options for selecting time ranges, channels, and search methods.
Step 8: Choose your search criteria
Common options include:
- Select a time window: For example, search between 9:00 AM and 3:00 PM on a specific date.
- Choose camera(s): Focus on the entry, lobby, or any camera likely to have captured the person.
- Provide a reference face: Upload or select a stored face snapshot from the NVR’s database.
The NVR will then process recorded data and return instances where similar faces were detected.
How Do You Interpret Search Results and Export Clips?
Step 9: Review face match results
In the video’s “Understanding Search Results” section, the system displays:
- A list/grid of candidate matches with face thumbnails.
- Associated details like time, camera, and confidence level (if supported).
You can:
- Click on an individual result to preview the clip associated with that match.
- Confirm whether it is the person you are looking for.
Step 10: Export selected video clips
Once you’ve identified relevant matches:
- Select the desired events or clips.
- Use the Export function to save them to a USB drive or network location in your preferred format.
This is ideal for:
- Providing evidence to law enforcement.
- Sharing incidents with management or HR.
- Archiving key events for internal investigations.
The video demonstrates how to select multiple clips and export them in one workflow, keeping your documentation process efficient.
Best Practices for Using Face Comparison Effectively in 2026
To get the most from Alibi Vigilant’s face comparison:
- Optimize camera placement: Position cameras at face height with good frontal views at key chokepoints.
- Maintain good lighting: Avoid strong backlighting and extremes of dark/bright that obscure facial features.
- Regularly update face libraries: Add or remove individuals as staffing, access privileges, or risk profiles change.
- Document your procedures: Create internal SOPs for who can run searches, how results are reviewed, and how exports are stored or shared.
- Respect privacy and legal guidelines: Follow applicable laws, internal policies, and any industry specific regulations regarding biometric or face-related data.
Older Information from the Video That Still Applies
The original walkthrough for the Alibi Vigilant AI powered NVR remains directly useful in 2026:
- You still start by selecting the correct NVR mode for face recognition.
- You must enable face comparison, then set monitoring tasks to define where and when the NVR watches for faces.
- Investigations rely on VCA Search for face matching, where you specify a time range, camera, and reference face.
- Search results present face thumbnails and timestamps, and you can export selected clips for external use.
By following these steps and pairing them with thoughtful policies and camera design, you transform your Vigilant NVR into a powerful AI driven security asset that saves time, strengthens investigations, and elevates your overall protection strategy.
