How to Fix Annoying Two-Way Audio Delays on Your Aqara Camera

The two-way audio feature on your Aqara camera is essential for communicating with family at home, instructing a courier, or deterring an unwanted visitor. When you're met with a significant delay between speaking and being heard, it can render this critical feature almost useless. This troubleshooting guide will help you identify the causes of audio lag and take practical steps to fix it.

Audio delay, also known as latency, is almost always a network-related issue. The audio from your camera has to be captured, digitised, sent over your Wi-Fi, through the internet to Aqara's servers, and then to your phone. Your voice has to make the same journey in reverse. A bottleneck anywhere along this path will cause a delay.

## Key Causes of Audio Lag

Let's look at the primary culprits that slow down the communication between your phone and your Aqara camera.

  • Weak Wi-Fi Signal: If your camera is installed far from your Wi-Fi router, the weak and unstable connection will struggle to handle the audio data stream efficiently.
  • Network Congestion: Your home Wi-Fi network is a shared resource. If other people are streaming movies, playing online games, or downloading large files, there might not be enough bandwidth available for your camera to use.
  • Slow Internet Upload Speed: Your ability to hear audio from the camera depends on your download speed, but your ability to speak through the camera depends on your internet connection's upload speed. Many internet plans have much slower upload than download speeds.
  • Outdated Firmware or App: Bugs in the camera's firmware or the Aqara Home app can sometimes cause performance issues, including audio lag.
  • Poor Mobile Connection: If you are not on Wi-Fi, a weak 4G or 5G signal on your smartphone will cause delays.

## Step-by-Step Troubleshooting to Eliminate Delay

Follow these steps to improve the speed and reliability of your two-way audio.

### 1. Strengthen Your Wi-Fi Connection

This is the most critical step. A strong, stable signal is essential.

  • Check Signal Strength: In the Aqara Home app, find the network settings for your camera. It should show you the signal strength. If it's "Weak" or "Poor", you've likely found the problem.
  • Move Your Router: If possible, try moving your Wi-Fi router to a more central location in your home, closer to the camera.
  • Install a Wi-Fi Extender or Mesh System: If you can't move the router, a Wi-Fi extender or a mesh Wi-Fi system is the most effective way to deliver a strong signal to every corner of your home. Install a node near the Aqara camera.

### 2. Ensure You Are on the 2.4GHz Band

Most Aqara cameras and smart home devices operate on the 2.4GHz Wi-Fi band because it provides better range than the 5GHz band. While your phone can be on 5GHz for normal operation, if you have persistent issues, ensure your router is properly configured to support 2.4GHz devices without issue.

### 3. Update Your Camera and App

Check for any available updates, as these often contain vital performance improvements.

  • Camera Firmware: Open the Aqara Home app, go to your camera's settings page, and look for a "Firmware Update" or "Device Update" option. Install any available updates.
  • Aqara Home App: Go to your phone's app store (Apple App Store or Google Play Store) and check if there is an update available for the Aqara Home app.

### 4. Test Your Internet Upload Speed

Use a free online speed test tool on a computer or phone connected to your home Wi-Fi. For smooth two-way talk, you should ideally have an upload speed of at least 1-2 Mbps available for the camera. If your upload speed is very low, you may need to contact your internet service provider to discuss upgrading your plan.

### 5. Restart Your Devices

Never underestimate the power of a simple reboot.

  • Restart the Camera: Unplug your Aqara camera from power, wait for 30 seconds, and plug it back in.
  • Restart Your Router: Do the same with your home router. This can clear up temporary glitches that may be slowing down your network.

By systematically improving your network environment and keeping your devices updated, you can dramatically reduce or eliminate the two-way audio delay on your Aqara camera.

Frequently Asked Questions

Most Aqara cameras, like many smart home devices, operate exclusively on the 2.4GHz Wi-Fi band. This band offers better range and wall penetration than 5GHz, which is crucial for home security. Ensure your phone is connected to your 2.4GHz network during setup.

A significant delay is most often caused by network latency. This could be a weak Wi-Fi signal at the camera's location, high congestion on your home network (too many devices), or a slow upload speed from your internet service provider.

Yes. If your phone has a poor 4G, 5G, or Wi-Fi connection, it will struggle to receive the audio stream from the camera and send your voice back in real-time, causing a noticeable lag. Try connecting to a strong Wi-Fi network and see if the problem improves.

First, try restarting your camera and your home router. This simple step can often resolve temporary network glitches. If the problem persists, check for any firmware updates for your camera in the Aqara Home app, as updates often include performance improvements.
