Yes, many security cameras have audio, but the feature works differently from one model to another. Some cameras let you hear live sound, some save sound with video, and some let you speak through the camera. In Australian homes, audio can be handy for talking to a parcel courier, checking on a pet in a unit or reviewing activity near a side gate. Here are six reliable ways to check what a camera supports, along with privacy and installation points worth checking in Australia.
What Does Audio Mean on Security Cameras
The word “audio” can describe several separate features. A camera may offer one of them without supporting the others.
| Audio feature | What it does | Common use |
|---|---|---|
| Live listening | Plays sound from the camera through the app | Checking pets or hearing activity in another room |
| Audio recording | Saves sound with recorded video | Reviewing the context around an event |
| Two-way audio | Lets both sides listen and speak | Talking to visitors, couriers or family members |
| Speaker or siren | Plays your voice, a recorded message or an alert | Speaking to someone or drawing attention to activity |
A speaker does not confirm that the camera can hear or record sound. A microphone may support live listening without adding sound to saved clips.
Check for separate references to a microphone, audio recording and two-way audio in the product details.
6 Ways to Tell Whether Security Cameras Have Audio
A camera’s specifications, app controls and saved footage usually provide a clear answer.
1. Read the Official Specifications
Look at the product page or user manual for wording such as:
- Built-in microphone
- Built-in speaker
- Audio recording
- Two-way audio
- Two-way talk
- Push-to-talk
Two-way audio usually confirms that the camera contains both a microphone and a speaker. It does not always confirm that the conversation will appear in saved recordings.
2. Open the Live Camera Feed
Open the camera in its security camera app and look for a speaker, microphone or Talk button.
The speaker control usually turns incoming sound on or off. The talk button sends your voice through the camera’s speaker.
If no controls appear, check the app’s microphone permission and confirm that the correct camera is open. Some controls only appear after the live feed has fully loaded.
3. Check the Camera’s Own Audio Settings
Open the settings for the individual camera rather than the app’s main settings page.
Common controls include:
- Camera microphone
- Speaker volume
- Recorded audio
- Two-way talk
- Sound detection
Live listening and recorded sound may use separate settings. A camera can produce sound during a live view while saving silent video clips.
4. Play a Saved Clip
Open a recent event and check the playback controls for a sound or mute icon. Turn up the phone’s media volume and disconnect Bluetooth headphones if the audio is playing through another device.
Silent playback does not always point to a faulty microphone. Audio recording may be switched off even though live listening still works.

5. Test Live and Recorded Audio Separately
Ask another household member to stand a few metres from the camera and speak at a normal volume.
Listen to the live feed first. Then trigger a recording and play it back. The two tests show whether the camera provides live sound, recorded sound, or both.
Everyone involved should know that the test is taking place. Use a neutral test phrase rather than recording a private conversation.
6. Check Each Camera in the System
A security camera system may contain several models with different audio features. An indoor camera may support two-way talk, while an older outdoor camera only records video.
Recorders, hubs, and network video recorders can also affect how sound is stored or played. Review each camera channel separately instead of assuming that one setting covers the whole system.
Which Audio Feature Suits Your Home
The location and daily use matter more than the number of audio features listed on the box.
| Australian home setting | Useful audio feature | What to check |
|---|---|---|
| Front verandah | Two-way audio | A eufy video doorbell may give clearer conversation at the entrance |
| Apartment or unit living area | Live listening and two-way audio | Camera angle, shared walls and private rooms |
| Driveway or garage | Recorded audio | Traffic noise, echo and mounting height |
| Side gate | Two-way talk | Wi-Fi signal and nearby properties |
| Backyard | Live or recorded audio | Wind, weather exposure and neighbouring conversations |
| Shared strata entrance | Limited or disabled audio | Strata by-laws and body corporate approval |
A video doorbell often works better for parcel deliveries because the microphone and speaker sit close to the visitor. An indoor camera is usually better suited to pet checks, family communication, and general room monitoring.
Audio should match a clear task. Extra audio features add little value when the camera sits too far from the person or area being monitored.
Why Camera Audio May Sound Unclear
A working microphone can still produce weak or broken sound. Placement, background noise, and network quality often explain the problem.
The Camera Is Too Far Away
A camera mounted high under the eaves may capture a wide view but struggle with quiet speech below it. The same issue can affect cameras covering long driveways or large backyards.
Place cameras close enough to the activity area for usable sound while keeping the required field of view.
Wind Is Hitting the Microphone
Exposed side passages, driveways and front verandahs can be noisy on windy days. Speech may become difficult to hear even when the video remains clear.
A sheltered mounting point may reduce wind noise, provided the camera is still suitable for the location.
The Room Has Too Much Background Noise
Televisions, open windows, hard floors and passing traffic can cover quieter voices. Garages may add echo, while open-plan rooms can carry sound from several areas at once.
Test the camera during the time of day when it will be used most often.

The Wi-Fi Signal Is Weak
Remote listening and two-way talk rely on a stable network connection. Weak upload speeds can cause delays, gaps or robotic-sounding speech.
Recorded audio stored locally may still sound normal, even when the live app connection performs poorly.
The Phone Is Sending Sound Elsewhere
Bluetooth headphones, car audio systems and muted media controls can make the camera seem silent. App permissions and speaker volume can cause the same problem.
Check the phone and app controls before changing the camera position or resetting the device.
Privacy, Strata and Audio Recording in Australia
Camera placement should stay focused on the property and areas the household needs to monitor. A camera should not unnecessarily capture a neighbour’s windows, private backyard or conversations outside the property.
The Office of the Australian Information Commissioner explains that the federal Privacy Act generally does not cover cameras used by an individual in a private capacity. State and territory laws may still apply. People living in strata properties should also review the building’s by-laws. The OAIC provides more detail in its guidance on residential security cameras and privacy.
Audio recording needs extra care because surveillance-device laws vary across Australia. In New South Wales, secretly recording a private conversation may be an offence unless an exception applies. Sharing the recording may raise a separate legal issue. Legal Aid NSW’s guidance on recordings explains the basic position in that state. The current Surveillance Devices Act 2007 sets out NSW rules for surveillance devices.
A few checks can reduce privacy problems:
- Review the law in your state or territory.
- Check tenancy, strata and body corporate rules.
- Point the camera away from neighbouring private areas.
- Turn off the microphone in locations where sound is unnecessary.
- Tell people in the home how the camera is being used.
- Keep cameras out of bedrooms, bathrooms and other private rooms.
These points carry more weight in units, townhouses and strata buildings where entrances and outdoor spaces may be shared.
How to Compare Surveillance Cameras With Audio
Choose the audio function that matches the job you want the camera to handle.
Live Listening, Recording or Conversation
Live listening suits quick checks on pets or activity around the home. Recorded audio can add context to saved events. Two-way talk suits entrances, family areas and rooms where remote conversation may be useful.
For front-door conversations, compare security cameras with video doorbells. For pets and indoor living areas, see the range of eufy indoor cameras.
Location, Power and Wi-Fi
Check the proposed installation point for:

- Indoor or outdoor exposure
- Access to power
- Wi-Fi strength
- Direct sun, rain and wind
- Camera height
- Microphone direction
- Rental or strata restrictions
An indoor camera should remain indoors, even if its audio features sound suitable for a driveway or front verandah.
Storage and Microphone Controls
Check whether sound is saved with each clip, where the recording is stored and whether the microphone can be turned off separately.
Compatible eufy security cameras offer local storage without a required monthly cloud storage fee. Supported models may also provide optional cloud services. Local storage suits people who prefer to keep compatible recordings on-site and avoid an ongoing cloud plan.
Indoor Audio for Pets and Family Communication
A renter or pet owner may receive a movement alert from the living room but still need to hear what is happening or speak through the camera. In that setting, clear two-way communication matters more than outdoor weather protection.
The eufy Indoor Cam E220 has built-in two-way audio for real-time conversation through the camera. It fits indoor pet checks and family communication rather than exposed driveways or backyards.
Do You Need Audio on Your Security Cameras?
Many security cameras support sound, but the exact feature may be live listening, recorded audio or two-way talk. Australian homes also need to account for Wi-Fi coverage, background noise, camera position, privacy boundaries and local recording laws. Compare eufy’s indoor cameras, outdoor security cameras and video doorbells based on where each device will sit and how the household plans to use it.
FAQs
Q1. Do Security Cameras Record Audio All the Time?
No. Some cameras record sound continuously, some only add sound to event clips, and others record video without audio. Check the camera settings and recording mode.
Q2. Does Two-Way Audio Mean the Conversation Is Saved?
No. Two-way audio confirms that people can listen and speak through the camera. Recording the conversation is a separate feature and may need to be enabled.
Q3. Can I Turn Off the Microphone?
Yes. Many security cameras include a microphone control in the app. The setting may appear under audio, privacy or individual camera controls.
Q4. Can a Security Camera Record Audio Without Internet Access?
Yes. Some cameras can save audio to local storage without an internet connection. Remote listening and two-way talk usually need internet access.
Q5. Is a Video Doorbell Better for Speaking to Parcel Couriers?
Yes, in most front-entry settings. The microphone and speaker sit near the visitor, which often gives clearer sound than a security camera mounted high above the verandah.
