Introduction

Unifi cameras are designed to provide reliable surveillance, but gaps in footage can occur due to connectivity, configuration, or hardware issues. This guide covers quick fixes, in-depth troubleshooting, and long-term care to ensure your system works as intended. Whether you're dealing with intermittent recordings or complete gaps, the steps below will help you identify and resolve the issue.

Quick Fixes to Restore Recordings

Before diving into advanced diagnostics, try these 30-second checks to address common causes of missed recordings:

  • Power Cycle Your Camera: Unplug the camera for 30 seconds, then reconnect it. This can resolve temporary glitches.
  • Restart the UniFi Protect App: Close the app completely and reopen it. This refreshes the connection to your cameras.
  • Check LED Status: A solid green LED indicates normal operation. Blinking or red lights may signal power or connectivity issues.
  • Verify Power Cable/Battery: For wired models, ensure the transformer is functioning. For battery-powered models like the AI 360, check the battery level in the app and charge if necessary.
  • Check App Login: Ensure you're logged into the correct UniFi Protect account. Incorrect login details can prevent the app from accessing camera data.

Check Your Wi-Fi Band and Signal Strength

Weak Wi-Fi signals are a common cause of missed recordings. Follow these steps to assess and improve your connection:

Determine Your Wi-Fi Band

UniFi cameras support both 2.4GHz and 5GHz bands. The 2.4GHz band offers better range but slower speeds, while the 5GHz band provides faster speeds but shorter range. For optimal performance, ensure your camera is on the 2.4GHz band unless you're using a modern router that supports both.

Check Signal Strength

In the UniFi Protect app, navigate to the camera's settings and look for the Signal Strength indicator. A signal strength of -70dBm or higher is ideal. If the signal is weak (below -80dBm), consider the following:

  • Relocate the Router: Move your router closer to the camera or place it in a central location.
  • Install a Wi-Fi Extender: Use a UniFi U6 or similar extender to boost coverage in areas with poor signal.
  • Avoid Obstacles: Ensure there are no solid walls, metal objects, or thick plaster between the router and camera. UK homes with cavity walls or solid brick construction may require additional extenders.

Optimize Router Settings

Access your router's settings via a web browser and ensure the following:

  • Enable WPA2 or WPA3 Encryption: Avoid outdated protocols like WEP.
  • Disable Quality of Service (QoS): This can throttle camera traffic, leading to dropped connections.
  • Set Channel Width to 20MHz: This improves range and reduces interference in crowded networks.

Update Firmware and Router Settings

Outdated firmware or incorrect router configurations can cause missed recordings. Follow these steps to ensure your system is up to date:

Update Camera Firmware

Open the UniFi Protect app, select the camera, and navigate to Settings > Firmware Update. If an update is available, follow the prompts to install it. Firmware updates often resolve bugs and improve compatibility with your network.

Update Router Firmware

Log into your router's admin interface (usually via a web browser) and check for firmware updates. Manufacturers like TP-Link, Netgear, and Ubiquiti regularly release updates to improve stability and performance.

Adjust Port Forwarding Settings

If your cameras are on a public network, ensure the following ports are open:

  • TCP/UDP 554 (RTSP)
  • TCP 80 (HTTP)
  • TCP 443 (HTTPS)

These ports allow the UniFi Protect app to communicate with your cameras. If you're unsure about your router's settings, consult the manufacturer's documentation or use a port forwarding tool like Port Checker.

Factory Reset and Re-pairing

If basic fixes fail, a factory reset can resolve hidden configuration conflicts. Follow these steps for different models:

For AI 360 (PoE)

  • Press and hold the reset button for 5-10 seconds until the LEDs indicate the restore has begun.
  • Once reset, re-pair the camera via the UniFi Protect app by selecting Add Camera > Manual Setup.

For G5 Bullet (PoE)

  • Press and hold the reset button for 5-10 seconds until the LEDs indicate the restore has begun.
  • Re-pair the camera via the UniFi Protect app, ensuring it's connected to the correct Wi-Fi network and UniFi Protect system.

For G5 PTZ (PoE)

  • Press and hold the reset button for 5-10 seconds until the LEDs indicate the restore has begun.
  • Re-pair the camera via the UniFi Protect app, ensuring the PoE switch supports 802.3at.

After re-pairing, verify the camera's settings in the app and ensure it's set to record continuously or on motion detection, depending on your needs.

Understanding the Root Cause

Missed recordings can stem from several factors, including:

  • Weak Wi-Fi Signal: As discussed earlier, poor signal strength can cause the camera to disconnect intermittently.
  • Outdated Firmware: Firmware updates often include bug fixes and performance improvements.
  • Incorrect Motion Detection Settings: Too low a sensitivity setting may miss events, while too high a setting can cause false triggers.
  • Power Issues: Faulty transformers or batteries can cause the camera to power off unexpectedly.
  • Storage Full or Corrupted: Ensure the NVR or local storage is not full and that microSD cards are functioning properly.

UK-specific challenges like solid brick walls, cavity walls, and foil insulation can exacerbate Wi-Fi signal issues. Modern double-glazed windows may also block signals, so consider installing Wi-Fi extenders in such cases.

Prevention and Long-Term Care

To avoid future issues, follow these best practices:

  • Regular Firmware Updates: Keep your camera and router firmware up to date to ensure compatibility and performance.
  • Monitor Signal Strength: Use the UniFi Protect app's Network Diagnostics feature to track signal strength and adjust your setup as needed.
  • Use High-Endurance MicroSD Cards: If using microSD cards, choose models designed for continuous recording (e.g. Samsung PRO Endurance, SanDisk High Endurance).
  • Schedule Regular Backups: Use the UniFi Protect app to back up camera configurations and recordings periodically.
  • Avoid Overloading the Network: Limit the number of devices on your network to ensure sufficient bandwidth for your cameras.

Replacement Decisions

If troubleshooting fails and your camera is beyond repair, consider the following:

  • Wired vs. Battery-Powered Cameras: Wired models like the G5 Bullet typically last 5-8 years, while battery-powered models like the AI 360 last 3-5 years. Replace batteries if the camera frequently powers off.
  • NVR HDD Lifespan: Surveillance-rated HDDs (e.g. WD Purple, Seagate SkyHawk) last 3-5 years with continuous use. Replace drives if they show signs of failure.
  • Consumer Rights Act 2015: UK consumers have up to 6 years to claim faulty goods under the Consumer Rights Act 2015 (5 years in Scotland). If your camera is under warranty, contact the manufacturer for repairs or replacements.
