Tend Camera Audio Not Working? Try These Fixes Now
If your Tend camera is not capturing or playing back audio, this guide covers the most common causes — from muted app settings to firmware bugs — with targeted solutions to restore sound quickly.
Quick Fixes to Restore Tend Camera Audio
Start with these checks before adjusting any settings:
- Check the mute toggle – In the TendSecure App, open your camera's live view and verify the microphone icon is not muted. This is the most commonly overlooked audio setting.
- Restart your camera – Unplug the power cable (or remove the battery) for 10 seconds, then reconnect. This clears temporary audio glitches.
- Refresh the app – Close the TendSecure App completely, then reopen it. Force-quit the app through your device's settings if needed.
- Check speaker volume – Ensure your phone's media volume is not set to zero when using two-way audio or playback.
- Verify two-way audio support – The Tend Lynx Indoor 2 supports two-way audio; not all Tend models include a speaker. Check your model's spec sheet if the speaker option is greyed out in the app.
Check Your Tend Camera's Wi-Fi Band Settings
Tend cameras rely on a stable Wi-Fi connection for audio transmission. Follow these steps to optimise your network:
Ensure 2.4GHz Band is Selected
Tend cameras only support 2.4GHz Wi-Fi (802.11b/g/n). Open your router's settings and confirm that the 2.4GHz band is enabled. If your router uses dual-band (2.4GHz and 5GHz), ensure the camera is connected to the 2.4GHz network. Avoid 5GHz bands, as they have shorter range and are more prone to interference.
Verify RSSI Signal Strength
Open the TendSecure App and navigate to Device Health → Signal Strength. A strong connection should display an RSSI of -60 dBm or higher. If the signal is weak (below -70 dBm), move the camera closer to the router or install a Wi-Fi extender.
Adjust Router Settings
Some routers have Quality of Service (QoS) settings that prioritise certain devices. Log into your router's admin panel and ensure Tend cameras are not being throttled. If your router has a guest network, connect the camera to the main network instead.
Update Firmware
Outdated firmware can cause audio issues. In the TendSecure App, go to Device Settings → Firmware Update. If an update is available, install it and restart the camera. Firmware updates often include bug fixes and performance improvements.
Check for Interference
Wi-Fi interference from microwaves, cordless phones, or Bluetooth devices can disrupt audio transmission. Turn off nearby devices that operate on the 2.4GHz band and test the camera again.
Is your camera battery-powered or wired?
- Battery-powered (Lynx Solar) → Check battery level in the app — charge via USB if below 20%.
- Wired (Lynx Indoor, Lynx Pro) → Check the DC power adapter is firmly connected at both ends.
Factory Reset and Advanced Diagnostics
If basic fixes fail, perform a factory reset and run advanced diagnostics:
Factory Reset Tend Cameras
- Tend Lynx Indoor: Press and hold the button on the back for 4 seconds until the LED turns off.
- Tend Lynx Pro: Press and hold the factory reset button on the side for 10 seconds.
- Tend Lynx Solar Camera: Press and hold the button on the back for 4 seconds until the LED turns off. After resetting, re-pair the camera through the TendSecure App and reconfigure settings.
Access Diagnostic Logs
Some Tend cameras allow diagnostic logs to be exported. In the TendSecure App, go to Device Diagnostics → Export Logs. Send these logs to Tend support for analysis.
Contact Manufacturer Support
If audio issues persist, visit Tend's official support page for further assistance. Provide details about your camera model, firmware version, and steps you've already taken.
Understanding Common Causes of Tend Camera Audio Failure
Audio issues often stem from connectivity, firmware, or hardware problems. UK-specific challenges, such as solid brick walls or Low-E coated windows, can severely weaken Wi-Fi signals. Tend cameras require a minimum of 2 Mbps upload speed for reliable audio. Outdated firmware or incorrect app settings can also disrupt functionality. Ensure your camera is positioned within 15-20 metres of the router and avoid obstructions that reduce signal strength.
A Managed Alternative for Persistent Issues
If audio problems keep recurring after firmware updates and resets, a professional system may be more suitable. scOS uses professional-grade IP cameras with hardware audio processing, eliminating the app-dependent audio pipeline that causes issues with consumer cameras. Two-way audio and monitoring work regardless of your phone's notification settings.
Preventing Future Tend Camera Audio Problems
To avoid recurring audio issues, follow these best practices:
- Regular maintenance: Check firmware updates monthly and restart devices periodically.
- Optimal placement: Position cameras within 15-20 metres of the router, avoiding thick walls or metal obstructions.
- Battery care: For battery-powered models, charge fully before installation and replace batteries every 2-3 years.
- Monitor signal strength: Use the TendSecure App to track RSSI levels and adjust router settings as needed.
- Avoid interference: Keep cameras away from microwaves, cordless phones, and Bluetooth devices.
When to Replace Your Tend Camera
Tend cameras typically last 3-5 years for battery-powered models and 5-8 years for wired models. Signs that replacement is needed include:
- Audio failure that persists after troubleshooting
- Battery degradation (less than 20% charge retention)
- Firmware end-of-life (no updates available)
- Physical damage to the camera or lens
Under the Consumer Rights Act 2015, UK consumers have up to 6 years to claim faulty goods. If your camera is within this period and shows signs of failure, contact Tend support for a replacement or repair.
