Introduction: Reolink Facial Recognition Not Working? Here’s How to Fix It

If your Reolink camera is failing to detect or recognize familiar faces, you’re not alone. This guide covers brand-specific troubleshooting steps, from quick fixes to advanced diagnostics. Whether you’re using the Argus Track or RLC-1212A, we’ll walk you through solutions tailored to Reolink’s unique features like TrackMix auto-tracking and on-device AI processing. By following these steps, you’ll restore accurate facial recognition without relying on cloud subscriptions or unnecessary hardware upgrades.

Quick Fixes for Reolink Facial Recognition Issues

Before diving into complex diagnostics, try these 30-second solutions:

  • Power cycle your camera: Unplug the power adapter (or remove batteries for battery models) for 10 seconds, then reconnect. This resolves temporary glitches in the Reolink App or camera firmware.

  • Restart the Reolink App: Close the app completely, then reopen it. This clears cached data that might interfere with facial recognition training or smart detection.

  • Check the LED status: A solid blue light indicates the camera is connected to the network. A blinking red light suggests a low battery (for battery models) or a failed firmware update.

  • Verify power supply: For Argus Track models, ensure the battery is fully charged. For RLC-1212A PoE models, confirm the transformer voltage is between 16-24V AC (check via the Device Info section in the app).

  • Confirm app login: Log out of the Reolink App and re-login using your account. This ensures your device is properly paired and facial recognition settings are accessible.

Step-by-Step: Troubleshooting Reolink Facial Recognition

Check Your Camera’s Wi-Fi Band Settings

Reolink cameras support dual-band Wi-Fi (2.4GHz and 5GHz). For optimal facial recognition performance, ensure your camera is connected to the 2.4GHz band. Follow these steps:

  1. Open the Reolink App and go to Device Settings → Wi-Fi Network.
  2. Select 2.4GHz if available. Some routers hide the 2.4GHz network by default — check your router’s settings to ensure it’s visible.
  3. Save the changes and wait 1 minute for the camera to reconnect.

If your camera is on the 5GHz band, switch it to 2.4GHz to avoid latency that could disrupt facial recognition accuracy.

Update Firmware for Reolink Facial Recognition

Outdated firmware can cause facial recognition failures. To update:

  1. In the Reolink App, navigate to Device Settings → Firmware Update.
  2. Tap Check for Updates. If an update is available, follow the prompts to install it. Ensure the camera remains powered during the update.
  3. After the update, restart the camera and retrain any faces in the Familiar Face Detection section.

Reconfigure Facial Recognition Settings

  1. Open the Reolink App and go to Device Settings → Facial Recognition.
  2. Ensure Familiar Face Detection is enabled. For Argus Track models, adjust Detection Sensitivity and Object Size Filters under Advanced Settings.
  3. If using the RLC-1212A, confirm TrackMix auto-tracking is activated in the app’s Smart Detection menu. This ensures the camera follows detected persons with the telephoto lens while maintaining an overview with the wide lens.

Factory Reset for Persistent Issues

If facial recognition remains unresponsive, perform a factory reset:

  • For Argus Track (battery model): Press and hold the Reset button for more than 5 seconds until the LED flashes red and blue.

  • For RLC-1212A (PoE model): Press and hold the Reset button for about 10 seconds until you hear a short music tone.

  • For Reolink Video Doorbell (Wi-Fi model): Use a paperclip to press the reset button until the LED blinks rapidly.

After resetting, re-pair the camera in the Reolink App and retrain faces from scratch.

Use Diagnostic Tools in the Reolink App

The Reolink App includes tools to diagnose facial recognition issues:

  1. Go to Device Info → Network Status. Check if the camera is connected to the correct Wi-Fi band and signal strength (RSSI) is above -70dBm.
  2. Test push notifications via the Push Notification Test option. If notifications fail, check your router’s firewall settings or port forwarding (port 80 for HTTP, 443 for HTTPS).
  3. Review Device Health logs for errors related to facial recognition or AI processing.

Advanced Diagnostics: When Basic Fixes Fail

If facial recognition still fails after the above steps, proceed with these advanced checks:

Analyze Diagnostic Logs

  1. In the Reolink App, go to Device Settings → Diagnostic Logs.
  2. Look for entries related to facial recognition engine, AI processing, or camera firmware. If logs show errors like AI engine timeout or face training failed, contact Reolink support directly via https://support.reolink.com/hc/en-us/.

Contact Reolink Support with Device-Specific Info

When reaching out to Reolink, provide:

  • Your camera model (e.g. Argus Track, RLC-1212A)
  • Firmware version (found in Device Info)
  • A screenshot of the Diagnostic Logs section
  • A brief description of when the facial recognition issue occurs

This information helps support teams identify if the problem is related to a known firmware bug or a hardware-specific limitation.

Root Causes: Why Reolink Facial Recognition Might Fail

Common causes include:

  • Poor lighting: Facial recognition requires adequate illumination. Avoid low-light conditions or areas with direct sunlight glare.
  • Incorrect camera positioning: Ensure the camera is angled between 15° and 30° from the horizontal plane and within 5m (16ft) of the subject.
  • Network instability: Weak Wi-Fi signals (RSSI < -70dBm) can disrupt AI processing, especially on Argus Track models.
  • Outdated firmware: Older firmware versions may lack support for the latest facial recognition algorithms.
  • UK-specific challenges: High humidity and frequent temperature swings can affect battery performance in Argus Track models. Use self-amalgamating tape on outdoor connections to prevent corrosion.

Prevention: Keeping Reolink Facial Recognition Working Long-Term

Full disclosure: we built scOS to address exactly this — the frustration of cameras that depend on facial recognition to function. scOS uses permanently powered cameras connected via ethernet.

To prevent future facial recognition issues:

  • Schedule regular firmware updates through the Reolink App’s Firmware Update section.
  • Train faces in varied lighting conditions to improve recognition accuracy.
  • Monitor battery levels for Argus Track models and replace batteries every 3-5 years.
  • Use high-endurance microSD cards for models storing facial recognition data locally.
  • Check router settings monthly to ensure 2.4GHz Wi-Fi is accessible and port 80/443 is open.

Replacement Decisions: When to Upgrade Your Reolink Camera

If your Reolink camera is over 5 years old or shows signs of battery degradation (Argus Track models), consider upgrading to a newer model with enhanced TrackMix auto-tracking or smart detection. Under the Consumer Rights Act 2015, UK consumers have up to 6 years to claim faulty goods. However, if troubleshooting exceeds 30 minutes without success, the issue is likely hardware-related, and replacement is recommended.

For battery-powered models, expect a lifespan of 3-5 years. For wired models, expect 5-8 years with proper maintenance. Always use surveillance-rated HDDs (e.g. WD Purple) for NVR systems to avoid data loss.
