Your Tend Camera Isn't Recognising Faces? Here's the Fix

If your Tend camera's facial recognition feature is failing to detect or identify familiar faces, this guide will help you resolve the issue. Common causes include incorrect training data, poor lighting conditions, or outdated firmware. By following the steps below, you'll restore accurate face detection using Tend's unique tools and model-specific features.

Quick Fixes to Try First

For immediate resolution, try these 30-second checks:

  • Power cycle your camera: Unplug the power adapter (or remove the battery for solar models) for 30 seconds, then reconnect. This resets temporary glitches.
  • Restart the TendSecure App: Close the app completely and reopen it. This refreshes the connection to your camera.
  • Check LED status: A solid blue light indicates normal operation. A flashing red light means low battery (solar models) or a connectivity issue.
  • Verify power cable/battery: For Tend Lynx Solar Camera, ensure the battery is above 20% in the Device Health section. For wired models, check the transformer at the junction box supplies 16-24V AC.
  • Check app login: Ensure you're logged into the TendSecure App with the account linked to your camera. If unsure, try logging out and back in.

Check Your Camera's Wi-Fi Band Settings

Tend cameras require 2.4GHz Wi-Fi only (802.11b/g/n) for facial recognition to function correctly. To verify:

For Tend Lynx Pro and Solar Camera

  1. Open the TendSecure App
  2. Tap Device Settings → Wi-Fi Settings
  3. Ensure 2.4GHz mode is enabled. If 5GHz is selected, disable it and restart the camera.

For Tend Lynx Indoor 2

  1. Access the camera's Device Health section in the app
  2. Look for Wi-Fi Band status. If it shows 5GHz, disable it via your router's settings and recheck the app.

Is your camera battery-powered or wired?

  • Battery-powered → Check battery level in the app — charge fully if below 20%
  • Wired → Check the transformer voltage at the junction box — must supply 16-24V AC

Update Your Camera's Firmware

Outdated firmware can cause facial recognition errors. To update:

For All Tend Models

  1. Open the TendSecure App
  2. Navigate to Device Settings → Firmware Update
  3. If an update is available, follow the on-screen instructions. Ensure your camera is connected to 2.4GHz Wi-Fi during the process.

For Tend Lynx Pro

  1. After updating, check the Motion detection status in the app. If disabled, enable it to allow facial recognition triggers.

Verify Cloud Connection and Face Library Settings

Tend's facial recognition relies on cloud processing. To check:

  1. In the TendSecure App, go to Device Health → Cloud connection check
  2. Ensure the status shows Connected. If Disconnected, follow these steps:
  • Check your router's firewall settings. Allow ports 80, 443, and 8080 for Tend cameras.
  • For Tend Lynx Pro, ensure your internet plan meets the 2 Mbps upload requirement.

Manage Face Library Settings

  1. Open the TendSecure App
  2. Go to Device Settings → Face Library
  3. Ensure Familiar Face Detection is enabled. If disabled, toggle it on and retrain faces.

Factory Reset and Advanced Diagnostics

If basic fixes fail, perform a factory reset specific to your model:

For Tend Lynx Indoor 2

  1. Press and hold the button on the back for 4 seconds until the front LED turns off.
  2. Wait 30 seconds, then reconnect the power adapter.
  3. Re-add the camera to the TendSecure App.

For Tend Lynx Pro

  1. Press and hold the factory reset button on the side for 10 seconds.
  2. Reconfigure the camera in the app, ensuring 2.4GHz mode is selected.

For Tend Lynx Solar Camera

  1. Press and hold the button on the back for 4 seconds until the front LED turns off.
  2. Recharge the battery fully before re-adding the camera.

After resetting, check the Device Health section for any error messages. If issues persist, contact Tend support at https://support.tendinsights.com with your camera model and firmware version.

Understanding the Root Causes

Facial recognition failures on Tend cameras often stem from:

  • Incorrect Wi-Fi band settings (5GHz disqualifies facial recognition)
  • Poor lighting conditions (direct sunlight or shadows degrade accuracy)
  • Battery issues on solar models (below 20% reduces performance)
  • Outdated firmware causing compatibility problems
  • Incorrect face training (poor quality images or incomplete data)

UK-specific challenges include high humidity affecting battery life and frequent temperature swings causing condensation on camera lenses. Ensure your Tend camera is installed in a sheltered location with adequate lighting for optimal facial recognition.

Prevention and Long-Term Care

Maintain your Tend camera's facial recognition accuracy with these tips:

  • Train faces during daylight hours when lighting is optimal
  • Update firmware regularly via the TendSecure App
  • Avoid direct sunlight or shadows on the camera lens
  • Check battery levels monthly for solar models
  • Enable motion detection in the app to trigger facial recognition

Full disclosure: we built scOS to address exactly this — the frustration of cameras that depend on facial recognition to function accurately. scOS uses permanently powered cameras connected via ethernet, eliminating battery degradation and intermittent connectivity.

When to Consider Replacement

Tend cameras typically last 5-8 years for wired models and 3-5 years for solar models. Signs your camera may need replacement include:

  • Persistent facial recognition failures after all fixes
  • Battery degradation (solar models below 20% capacity)
  • Firmware EOL (end of life) notifications in the app
  • Physical damage to the camera housing or lens

Under the Consumer Rights Act 2015, UK consumers have up to 6 years to claim faulty goods. If your camera is under warranty, contact Tend support directly for replacement options.

Frequently Asked Questions

Tend's facial recognition relies on proper lighting, clear camera positioning, and accurate user training. If recognition fails, first check the **Device Health** section in the TendSecure App. Look for **Cloud connection check** status and **Motion detection status**. If motion detection is disabled, facial recognition won't trigger. Ensure your camera is within 5 metres of the main router and using **2.4GHz mode**. For the **Tend Lynx Pro**, verify your upload speed meets the 2 Mbps minimum requirement. If all settings are correct, try retraining faces in the **Face Library** section of the app.

For the **Tend Lynx Solar Camera**, a weak battery can degrade facial recognition accuracy. Check battery level in the **Device Health** section. If below 20%, charge fully before retraining faces. For wired models like the **Tend Lynx Indoor 2**, ensure the transformer at the junction box supplies 16-24V AC. Poor power delivery can cause intermittent operation. If using **Tend Lynx Pro**, confirm your internet plan meets the 2 Mbps upload requirement. If issues persist after these checks, perform a factory reset via the **Factory reset button** on the camera's side.

To retrain faces on Tend cameras, open the TendSecure App, navigate to **Device Settings** → **Face Library**. Tap the face you want to update and follow the on-screen prompts to capture new images. Ensure lighting is consistent (avoid direct sunlight or shadows) and the subject faces the camera directly. For best results, train faces during daylight hours when the **Tend Lynx Solar Camera**'s battery is above 50%. If training fails, check the **Cloud connection check** status and ensure firmware is up to date.

If your Tend camera's facial recognition fails after a firmware update, first check the **Device Health** section in the app for any error messages. If no errors appear, try reverting to the previous firmware version via the **Firmware Update** menu in the TendSecure App. For the **Tend Lynx Pro**, ensure your router's firewall allows ports 80, 443, and 8080. If issues persist, contact Tend support at https://support.tendinsights.com with your camera model and firmware version.
