How to Fix UniFi Protect Camera Mic Not Recording Audio
- Mic/audio disabled in settings
- Privacy or mute enabled
- Camera has no mic (model)
Problem Description
Your UniFi Protect camera's microphone is not capturing audio — recordings play back with no sound, and the live view has no audio even with the speaker unmuted. The microphone must be explicitly enabled in camera settings, volume must be set high enough, firmware must be current, and the mic hardware must be undamaged.
Why This Happens in Real Homes
When a UniFi Protect camera's microphone isn't recording audio, the mic is usually just disabled — either audio recording is off in settings, a privacy/mute toggle is on, or the recording profile doesn't include audio. As with any UniFi audio issue, confirm the model actually has a microphone first.
Enable the microphone and audio recording in the camera's Protect settings, turn off any privacy/mute, and make sure the recording profile captures audio. Some regions default audio off for legal reasons — enable it where it's permitted. Update firmware, and if a mic-equipped, audio-enabled camera still captures nothing, the microphone hardware may be failing and UI support can help.
Symptoms
- Microphone not capturing audio
- Mic silent
- No audio from the mic
- Mic not working
- No sound captured
- Mic disabled behavior
- Audio dead
- Mic not recording
Recognize these? Here's what usually causes it.
Common Causes
- Mic/audio disabled in settings
- Privacy or mute enabled
- Camera has no mic (model)
- Audio recording profile off
- Regional audio restriction
- Firmware issue
- Mic hardware fault
- Controller audio setting
Most fixes happen in the first 3 steps.
Do not assume live audio guarantees recorded audio retention.
Tools & Requirements
Step-by-Step Solution
Enable the microphone in camera settings
Audio recording is off by default. In Protect: Devices > select camera > Settings > scroll to the audio section. Enable the 'Microphone' toggle. Some Protect versions show this under Recording settings as 'Record Audio.' After enabling: the camera starts capturing audio immediately. Check live view with the speaker icon unmuted to verify audio is working in real time. If the toggle is grayed out: the camera model may not have a microphone or the firmware needs updating.
Increase microphone volume and sensitivity
If the microphone is enabled but recorded audio is inaudible: the volume is too low. In Protect: Devices > select camera > Settings > Microphone Volume or Mic Sensitivity. Set to 75-100%. Test by clapping near the camera and checking the recording. If the camera is mounted high (8-10 feet): the microphone picks up less ambient sound — maximum sensitivity may be needed. Some cameras (G4 Bullet, G5 Bullet) have the mic on the front face — obstructions or weather seals can muffle the microphone.
Verify audio in live view vs recordings separately
Open live view and unmute the speaker icon. If you hear live audio: the mic hardware works. Now check a recording: go to the timeline, select a recent clip from after you enabled audio, and play it back. If live has audio but recordings do not: the 'Record Audio' setting is off separately from the mic toggle (some Protect versions have two separate settings). If neither has audio: the mic may be hardware defective or the camera firmware has an audio bug.
Update the camera firmware
Audio bugs (mic not initializing after boot, audio dropping after a few hours) have been fixed in recent firmware updates. In Protect: Devices > select camera > check for firmware updates. Apply any available update and wait for the camera to reboot. After the update: re-verify audio in both live view and recordings. The G4 Doorbell in particular has had multiple firmware fixes for microphone sensitivity and echo cancellation issues.
Check for hardware microphone issues
If all software settings are correct, firmware is current, and still no audio: the microphone may be physically damaged. Outdoor cameras exposed to weather can accumulate moisture or debris in the microphone port. Inspect the camera's mic opening for blockage — use compressed air to clear debris. If the mic is water-damaged (common on cameras without proper drainage in heavy rain): the camera needs replacement. Contact Ubiquiti support with your proof of purchase for warranty claims.
Quick Solutions
Still having issues? This is usually the deeper cause below.
Camera issues that start suddenly almost always trace back to an upload bandwidth drop — run a speed test before assuming hardware failure.
Per-camera profile audits catch silent audio misconfigurations early.
Live view problems that start suddenly usually trace back to an upload speed drop — the camera itself is fine, the bandwidth path to the cloud isn't.
- Mic/audio disabled in settings
- Privacy or mute enabled
- Camera has no mic (model)
- Audio recording profile off
- Regional audio restriction
