• Verify power cable/battery: For battery-powered models like the G5 Turret Ultra, ensure the battery is fully charged. For wired models, check the PoE switch and transformer voltage (must be 16–24V AC for UK installations).
• Check app login: Ensure you’re logged into the correct account in the UniFi Protect app. If multiple users share the app, confirm the camera is assigned to the correct profile.

These quick fixes address the most common issues without requiring router settings or firmware updates. If these steps don’t resolve the issue, proceed to the deeper troubleshooting steps below.

Detailed Unifi Troubleshooting Guide for Unifi Hardware Failure

1. Check Your Unifi Camera’s Wi-Fi Band Settings

Unifi cameras often default to 2.4GHz Wi-Fi, but some models may struggle with connectivity on this band, especially in UK homes with older routers or interference from other devices. To optimize your camera’s Wi-Fi performance:

• Open the UniFi Protect app and navigate to the Device Health section.
• Select your camera and check the Wi-Fi band setting. If it’s set to 2.4GHz, try switching to 5GHz if your router supports it. However, note that 5GHz may not reach as far as 2.4GHz, so ensure your camera is within range of the router.
• If your camera fails to connect to the 5GHz band, revert to 2.4GHz and check for signal strength (see next step).

2. Update Your Unifi Camera’s Firmware

Outdated firmware can sometimes mimic hardware issues, especially on models like the AI 360 or G5 PTZ. To ensure your camera is running the latest firmware:

• Open the UniFi Protect app and go to the Camera section.
• Tap the Settings icon (gear icon) for the affected camera.
• Look for a Firmware Update option. If an update is available, follow the on-screen instructions to install it.
• If your camera is not showing an update option, check the Protect health dashboard for any firmware-related errors. If the dashboard indicates a firmware incompatibility, contact Unifi support for guidance on manually updating the firmware.

3. Use the Protect Health Dashboard for Error Logs

The Protect health dashboard is a powerful diagnostic tool in the UniFi Protect app that can help identify hardware issues. To access it:

• Open the UniFi Protect app and tap the Protect health icon (a shield with a checkmark).
• Look for any Camera adoption status errors, Device Health metrics, or Storage RAID status warnings. For example, if your NVR system is showing a Storage RAID status error, this may indicate a failing NVR HDD.
• If your AI 360 model is showing Device Health metrics like temperature thresholds exceeding safe limits, this could indicate overheating due to environmental factors (e.g. poor ventilation or excessive sunlight exposure).
• Use the Bandwidth monitor in the dashboard to check for unusual spikes that may indicate a hardware fault or misconfiguration.

4. Check for PoE Stability on G5 PTZ Models

Unifi’s G5 PTZ cameras require PoE+ (802.3at) to function correctly. If your camera is losing power intermittently, it could be due to an incompatible PoE switch or PoE injector. To troubleshoot:

• Verify your PoE switch supports 802.3at. If you’re using a PoE injector, ensure it’s compatible with the G5 PTZ model.
• For UK users, confirm your BS 1363 Type G sockets are RCD-protected and meet IP66 standards. If your G5 PTZ is installed outdoors, ensure the PoE switch is in a dry, protected location to avoid moisture-related failures.
• If your G5 PTZ is still losing power, try connecting it directly to a surveillance-rated PoE switch (e.g. Unifi U6-PoE). If the issue persists, contact Unifi support for a hardware replacement.

5. Check Storage RAID Status on NVR Systems

For Unifi NVR systems with Storage RAID, a hardware failure may be indicated by errors in the Storage RAID status section of the Protect health dashboard. To diagnose:

• Open the UniFi Protect app and go to the Storage RAID status section.
• Look for any RAID errors or NVR HDD failures. If a specific drive is flagged, it may be failing or incompatible with the UNVR Pro system.
• Replace the affected NVR HDD with a surveillance-rated drive (e.g. WD Purple or Seagate SkyHawk) designed for 24/7 operation.
• If your UNVR Pro system is showing Storage RAID status errors even after replacing the drive, contact Unifi support for further diagnostics.

Advanced Diagnostics for Persistent Unifi Hardware Issues

If basic troubleshooting steps have not resolved the issue, proceed with these advanced diagnostics:

Factory Reset for Specific Unifi Models

For models like the G5 Bullet or G5 Turret Ultra, a factory reset may be necessary to resolve hardware-related issues. To perform a factory reset:

• Locate the reset button on the camera. It is typically a small hole on the back or bottom of the device.
• Press and hold the reset button for 5–10 seconds until the LEDs indicate the restore has begun. This process may take up to 30 seconds.
• After the reset, reconfigure the camera via the UniFi Protect app. If the camera still fails to connect, check the Protect health dashboard for error logs.

Use the Protect Health Dashboard for Deep Diagnostics

The Protect health dashboard provides detailed insights into hardware and software performance. To use it effectively:

• Open the UniFi Protect app and tap the Protect health icon.
• Check the Device Health metrics for your camera or NVR system. Look for any temperature thresholds, firmware compatibility, or storage errors.
• If your AI 360 model is showing Device Health metrics like overheat warnings, this may indicate a hardware fault or incorrect configuration (e.g. using 1920x1920 resolution at 30fps on an incompatible model).
• Use the Bandwidth monitor to check for unusual spikes that may indicate a hardware fault or misconfiguration.
