Security Camera Without Audio: How to Turn the Mic Off

You can run most cameras as a security camera without audio even if the hardware has a microphone: turn off the audio or sound recording switch in the camera's own settings, not just the speaker icon on the live view. The speaker icon only mutes sound on your phone; the camera can still be recording it. After changing the setting, record a short clip and play it back to confirm it is silent.

This guide explains the difference between the camera's microphone and its speaker, how to find out what your model has, where the audio switch usually lives, and how to keep talk-back and the siren working while the microphone stays off.

Why some owners want video only

Your reason decides how thorough you need to be.

• Privacy at home. A camera in a living room or hallway picks up family conversations, phone calls and arguments. Many households are comfortable being seen on their own camera but not being overheard.
• Guests, helpers and staff. A nanny, a cleaner or shop staff may accept a visible camera but object to their conversations being recorded. Telling them clearly that the camera records picture only removes a lot of friction.
• Shared viewers. If you have shared the camera with relatives or colleagues, everyone with access can potentially listen in from their own phone. Turning audio off at the camera removes that for all of them at once.
• Local rules. In some places, recording conversations is treated differently from recording video, especially for people who have not agreed to it. This guide is not legal advice; if you are unsure, check local rules before recording sound, particularly in a workplace or a space other people use.

If your reason is privacy for other people, muting your own phone is not enough. You need the camera itself to stop capturing sound.

Microphone, speaker and the three audio features

Camera audio is often described as one feature, but it is three, and they use different parts.

1. Live listening. The camera's microphone picks up sound and streams it to your phone while you watch.
2. Audio in recordings. The same microphone's sound is saved with the video on the memory card or any cloud storage your model and region offer.
3. Talk-back (two-way audio). Your phone's microphone captures your voice and the camera's speaker plays it. A siren or voice warning also comes out of that speaker.

The point that matters: talk-back and the siren do not need the camera's microphone. They need the camera's speaker. So on most models you can stop the camera listening while still being able to speak through it or sound an alarm. Whether the app lets you separate them neatly depends on the model and firmware, which is why testing at the end is not optional.

Step 1: Check whether your camera has a microphone

Before hunting for settings, confirm what hardware you have. Not every camera has a microphone, and not every camera with a microphone has a speaker.

• Read the manual or the packaging for your exact model. Look for words like audio, microphone, two-way audio or talk-back. Product listings sometimes describe a camera as an "ip camera with mic" or an "audio video security camera"; that tells you there is a microphone, but not always whether there is a speaker.
• Look at the housing. A microphone is usually a tiny pinhole, often near the lens or on the underside. A speaker is normally a larger grille or a set of slots.
• Do a clap test. Open live view, make sure the speaker icon is on and your phone volume is up, then have someone clap or talk next to the camera. If you hear it on your phone, the camera has a working microphone and audio is currently enabled.
• Ask the seller if the documentation is unclear. They can tell you what the model in your box supports.

If the clap test gives you silence even with the icon on, either audio is already off in the camera settings, or the camera has no microphone. The settings check below will tell you which.

Step 2: Mute the live view on your phone (not enough on its own)

On the live view screen there is a speaker or sound icon. Tapping it so it shows crossed out stops sound playing on your phone.

This is useful when you simply do not want noise while watching, but understand its limits:

• It affects your phone only. A family member watching on their own phone can still hear.
• On most models it does not stop the camera recording sound to the memory card.
• It may switch back on the next time you open live view, depending on the app version.

Treat it as a convenience, not as turning the camera into a video-only device.

Step 3: Turn off audio in the camera's settings

This is the step that actually stops the camera capturing sound.

1. Open the camera in the app and tap the gear icon to reach its device settings. If you are not sure where things are, the tour of the main Yoosee app settings shows how the menus are laid out.
2. Look for an audio switch. It is usually in one of these areas: media or video settings, record settings, or a separate audio or sound section. The label might be audio, sound, record audio, microphone or audio recording. Menu names may differ slightly by app version.
3. Switch it off and leave the settings page normally so the camera receives the change.
4. Close and reopen the camera page and check the switch is still off. If it has flipped back, the change did not reach the camera; check the camera is online and try again.

If you cannot find any audio switch at all, there are three likely explanations: your model has no microphone, your app or firmware version does not offer the option, or the option sits under a heading you did not expect. Update the app, check for a firmware update in device settings, and look again before concluding it is missing.

Step 4: Confirm the recordings are really silent

Do not trust the toggle alone. Prove it.

1. Make some deliberate noise in front of the camera for half a minute: talk, clap, play music.
2. Wait a couple of minutes for the recording to be written.
3. Open playback for that time, as explained in the guide to watching Yoosee playback recordings, and listen with your phone volume up.
4. Open live view again and repeat the clap test.

If playback and live view are both silent, the microphone is effectively off for recording and listening. If you still hear sound in new recordings, the switch did not apply; repeat step 3, restart the camera by unplugging it briefly, and test again.

Remember that older recordings keep their sound. Turning audio off does not strip it from footage already on the card. If those older clips are the concern, delete or format them from the storage section, after exporting anything you need to keep.

Step 5: Keep talk-back and the siren working

Once audio is off, check the features you still want.

Talk-back. Open live view, hold the talk button and say something, while someone stands near the camera to confirm they hear you. On most models the speaker works independently of the microphone setting. On some firmware, though, the audio switch disables both directions together. If that happens on yours, you have to choose: keep audio off and lose talk-back, or keep audio on and rely on muting. If talk-back fails for other reasons, such as a missing permission on your phone, the checklist for two-way audio not working goes through the causes in order.

Keep in mind that with the microphone off, talk-back becomes one-way: people near the camera hear you, but you cannot hear their reply. That suits warnings and short messages, not conversations.

Siren and voice warnings. These play through the speaker, usually when motion detection triggers them or when you press a manual siren button, so the microphone setting normally has no effect on them. Still, test once: trigger motion during the armed hours, or use the manual siren button in live view if your model has one. The guide to setting up a camera with siren covers linking it to detection and scheduling it.

Step 6: Check every place the footage can be watched

Audio settings live on the camera, so they generally apply wherever the footage is viewed. It is still worth a quick check of each route people use.

• Shared accounts. Ask one person you have shared the camera with to open live view and confirm they hear nothing. While you are in the sharing list, remove anyone who no longer needs access; that is the simplest privacy fix of all.
• Computers. If anyone watches on a desktop client or an emulator, open it and repeat the clap test there.
• Exported clips. Clips saved to your phone before you changed the setting will still contain sound. Delete them if needed.

Physical options and what to avoid

Some people want certainty that a software switch cannot give. Your options are limited.

• Covering the pinhole with tape muffles sound but rarely silences it completely, and it can trap moisture on outdoor cameras. Treat it as a partial measure only.
• Opening the camera to disconnect the microphone is not recommended. It can damage the camera, break its weather sealing and may affect any warranty; check with the seller first.
• Choosing a model without a microphone is the cleanest answer if you are buying new. Ask the seller specifically, because listings for a "security camera with microphone" and a picture-only model can look almost identical.

If the camera is mounted high up and you need to reach it, switch off its power first and use a stable ladder or a helper. For anything involving mains wiring, use a qualified electrician.

Tell people the camera records video only

Turning the microphone off helps most when the people being filmed know about it. Tell the household, guests and staff that the camera records picture only. In a shop or office, a short notice near the camera is a practical way to do that. If you later switch audio back on, tell them again.

When to get help

Contact the seller or the support channel listed for your model if:

• The audio switch keeps turning itself back on after you save it.
• New recordings still contain sound with audio switched off, even after a restart and a firmware update.
• The manual lists an audio setting that never appears in the app.
• Talk-back or the siren stopped working after you changed audio settings, and switching audio back on does not restore them.

Have the device ID, the app version and the firmware version ready, plus a note of what you have already tried.

Frequently asked questions

Does muting the live view stop the camera recording sound?

Usually not. The speaker icon on the live view only controls sound on the phone you are holding. To stop the camera recording audio, turn off the audio or sound recording switch in the camera's device settings, then check a new playback clip is silent.

Can my family still hear audio if I turn it off on my phone?

Yes, if you only muted your own live view. Each person's phone has its own mute. Turning off audio in the camera's settings stops capture at the camera, which applies to everyone you have shared it with.

Can I turn off the mic but still talk through the camera?

Often, yes, but you will only be able to speak, not hear the reply. If talk-back stops working after you switch audio off, your firmware links both directions to one switch, and you have to choose between the two.

Will turning off audio remove sound from my old recordings?

No. The change only affects footage recorded from that moment on. Recordings already on the memory card keep their sound until they are overwritten, deleted or the card is formatted.

Is it legal to record audio with a home security camera?

It depends on where you live and who is being recorded, and the rules for sound can differ from those for video. This article cannot give legal advice. If you are unsure, check local rules, and consider keeping audio off in spaces used by guests, helpers or staff.

Does a camera without audio use less storage?

Audio adds a little to each recording, but video is by far the larger part, so turning the microphone off does not noticeably extend how many days a memory card holds. Recording mode, resolution and card size have a much bigger effect.
