Can Arlo Cameras Hear Sound? Find Out Here

Imagine you’re sitting on your porch with a cup of coffee, enjoying the morning breeze. Suddenly, you hear a faint crack in the backyard. You glance at your Arlo camera feed, but you’re unsure if it picked up the noise. You wonder: Can Arlo cameras hear sound? It’s a question many smart home users ask, especially when they’re relying on their cameras for security, peace of mind, or even baby monitoring. After all, a camera that sees is great—but one that hears? That’s next-level.

Whether you’re a new Arlo owner or considering upgrading your home security setup, understanding how these devices handle sound is crucial. Maybe you’ve caught a suspicious noise on your camera’s audio but aren’t sure if it’s reliable. Or perhaps you’re curious about whether Arlo can help you catch a late-night package thief or soothe a crying baby from another room. In this post, I’ll walk you through everything you need to know about Arlo cameras and sound—how they capture audio, what they can (and can’t) hear, and how to get the most out of their audio features. No fluff, no jargon—just real, practical insights from someone who’s tested these cameras in real-life situations.

How Arlo Cameras Capture Sound: The Tech Behind the Microphone

Built-in Microphones Across the Arlo Lineup

Most Arlo cameras come equipped with built-in microphones, allowing them to record audio alongside video. But not all models are created equal. For example, the Arlo Pro 4, Arlo Ultra 2, and Arlo Essential Spotlight all feature high-quality microphones designed to capture clear sound within a reasonable range—typically up to 25 feet (about 7.6 meters) in ideal conditions. These mics are tuned to pick up human voices, barking dogs, breaking glass, and other common household sounds.

However, it’s important to note that not every Arlo camera has audio capabilities. The Arlo Go, a cellular-powered outdoor camera, includes a mic, but older or budget models like the Arlo SmartHub (without a camera) or certain third-party add-ons might not. Always check the product specs before assuming audio is included.

Audio Quality and Environmental Factors

The quality of sound captured by your Arlo camera depends on several factors:

• Distance: The farther you are from the camera, the fainter the sound becomes. At 10 feet, voices are usually clear. Beyond 25 feet, even loud noises may be muffled or missed.
• Obstacles: Glass, walls, and dense foliage can block or distort sound. For instance, if your camera is mounted outside and you’re trying to hear someone talking on the other side of a window, the audio may be muffled.
• Wind and background noise: Outdoor cameras are especially vulnerable to wind noise, traffic, or rustling leaves. The Arlo Ultra 2 includes noise reduction tech to help, but it’s not perfect.
• Microphone sensitivity: Some models, like the Arlo Pro 4, allow you to adjust microphone sensitivity in the app. This helps reduce false triggers from distant noises while still catching important sounds nearby.

Here’s a real-life example: I once had an Arlo Pro 4 mounted above my garage. One evening, I received a motion alert and checked the live feed. The camera clearly showed a raccoon knocking over my trash can. But what really confirmed it wasn’t a human intruder? The crunching and scuttling sounds picked up by the mic. That audio clue saved me from a false alarm—and a midnight trip outside with a flashlight.

Two-Way Audio: Can You Talk Through Your Arlo Camera?

What Is Two-Way Audio?

Many Arlo cameras don’t just listen—they also talk back. This feature is called two-way audio, and it allows you to speak through the camera’s built-in speaker using your smartphone or tablet. Think of it like a walkie-talkie for your home. If someone’s at your door, you can say, “I’ll be right there,” even if you’re on the other side of town.

Two-way audio is available on most modern Arlo models, including:

• Arlo Pro 4
• Arlo Ultra 2
• Arlo Essential Indoor/Outdoor
• Arlo Video Doorbell (all versions)

The process is simple: when you open a live view in the Arlo app, you’ll see a microphone icon. Tap it, hold it, and speak. Your voice is transmitted instantly through the camera’s speaker. The delay is usually under a second—fast enough for real-time interaction.

Real-World Uses and Limitations

Two-way audio is incredibly useful in everyday scenarios:

• Package deliveries: Tell the courier to leave your parcel behind the plant or in the garage.
• Intruders or animals: Scare off raccoons, foxes, or curious neighbors with a firm “Hey! Get out of my yard!”
• Family communication: If your kids are playing outside, you can call them in for dinner without stepping outside.
• Pet monitoring: Calm a barking dog by speaking through the camera.

But it’s not magic. Here are a few limitations to keep in mind:

• Volume: The speaker is loud enough to be heard in a backyard or at a front door, but not across a football field. If someone is 30 feet away, they might not hear you clearly.
• Echo and feedback: If you’re standing near the camera while speaking, you might hear your own voice echo. Avoid this by staying away from the camera when using two-way audio.
• Internet dependency: Two-way audio requires a stable Wi-Fi connection. If your internet drops, you won’t be able to talk through the camera.

Pro tip: Use two-way audio in short bursts. Holding the mic button for 30 seconds straight can drain your phone’s battery and cause audio lag. Instead, speak in 5-10 second clips and wait for a response.

Audio Alerts and Smart Notifications: How Arlo Uses Sound for Security

Customizing Sound-Based Alerts

Arlo doesn’t just record sound—it can actually react to it. With smart notifications, you can set your camera to send alerts when it detects specific sounds, like glass breaking, a smoke alarm, or a baby crying. This is part of Arlo’s Smart Detection feature, available with an Arlo Secure subscription.

For example, you can enable:

• Glass Break Detection: The camera listens for the high-frequency sound of shattering glass and sends an immediate alert.
• Smoke/Carbon Monoxide Alarm Detection: Recognizes the unique 3-pulse pattern of most alarms and notifies you—even if you’re away.
• Baby Cry Detection: Useful for parents who want to know if their child is awake or distressed.
• Person, Animal, or Vehicle Detection: While these are primarily visual, audio can help confirm the alert (e.g., hearing a dog bark when the camera sees a pet).

To set this up, go to the Arlo app > select your camera > tap “Smart Alerts” > and toggle on the sound detection you want. You can even adjust the sensitivity—high for quiet homes, low for busy neighborhoods.

When Audio Alerts Work Best (and When They Don’t)

Sound-based alerts are powerful, but they’re not foolproof. Here’s when they shine—and when they fall short:

Works well:

• In quiet environments (e.g., a home at night)
• When the camera is within 15 feet of the sound source
• For high-decibel, distinct sounds (glass breaking, alarms)

Less reliable:

• In windy or noisy areas (e.g., near a busy street)
• For faint or muffled sounds (e.g., a whisper through a closed window)
• When the camera is mounted too high or behind glass

One user shared a story: their Arlo Ultra 2 detected a smoke alarm during a kitchen mishap while they were at work. The alert came in within seconds, and they were able to call the fire department before the situation escalated. That’s the power of smart audio detection.

But on the flip side, I once had a camera trigger a “glass break” alert because my neighbor’s kids were playing with a plastic toy that made a cracking noise. It was a false alarm—but it taught me to fine-tune the sensitivity. Lesson learned: always test your settings in your specific environment.

Privacy, Legal, and Ethical Considerations: What You Need to Know

Is It Legal to Record Audio with Your Arlo Camera?

This is a big one. While video recording in public or semi-public spaces (like your front yard) is generally legal, audio recording is a different story. In many U.S. states and countries, recording someone’s voice without consent can violate privacy laws—especially if it’s a private conversation.

For example:

• Two-party consent states (like California, Massachusetts, and Illinois) require all parties to agree before recording audio. If your camera picks up a conversation between two neighbors in their backyard, you could be legally liable—even if you didn’t intend to eavesdrop.
• One-party consent states (like Texas and Florida) only require one person in the conversation to consent. Since you own the camera, you’re covered—but it’s still a gray area if the conversation is clearly private.
• Outside the U.S.: Countries like Canada, Germany, and Australia have strict privacy laws. Always check local regulations before enabling audio.

Arlo addresses this by allowing you to disable audio recording in the app. If you’re in a high-privacy area or just uncomfortable with recording voices, you can turn off the microphone entirely. You’ll still get video, but no sound.

Best Practices for Ethical Audio Use

Even if it’s legal, consider these ethical tips:

• Inform neighbors: A simple note or conversation can prevent misunderstandings. Most people are fine with cameras that record video, but audio can feel intrusive.
• Position cameras wisely: Avoid pointing mics directly at neighbors’ windows or private areas.
• Use audio only when needed: Enable it for security alerts (like glass break), but disable it during normal monitoring.
• Review recordings carefully: If you accidentally capture a private conversation, delete it promptly.

I once had a neighbor complain that my Arlo camera “recorded their kids arguing.” I hadn’t even noticed the audio—but after checking, I saw it was picking up sound from their open window. I adjusted the camera angle, lowered the mic sensitivity, and added a privacy sticker on the lens. Problem solved, and we’re still on good terms.

Maximizing Audio Performance: Tips and Troubleshooting

Optimizing Your Camera for Clear Sound

Want the best audio experience from your Arlo camera? Try these tips:

• Mount at ear level: For indoor cameras, 5-6 feet off the ground captures voices best. For outdoor, aim for 7-8 feet to avoid ground-level noise.
• Use windshields: Arlo sells weather-resistant covers that reduce wind noise. DIY options (like foam covers) can help too.
• Clean the mic regularly: Dust, rain, and bugs can clog the microphone grille. Wipe it gently with a dry cloth every few weeks.
• Update firmware: Arlo frequently releases updates to improve audio processing. Keep your cameras updated via the app.
• Test in different conditions: Check how your camera performs at night, in rain, and during wind to understand its limits.

Common Audio Issues and Fixes

Here are some problems you might encounter—and how to solve them:

Issue	Possible Cause	Solution
No sound in recordings	Microphone disabled or faulty	Check app settings > Audio > Enable microphone. Restart camera if needed.
Echo or feedback during two-way audio	User too close to camera	Move away from camera when speaking. Use headphones to avoid audio loop.
Wind noise in outdoor recordings	Exposed microphone	Install a windscreen or reposition camera to face away from prevailing winds.
Delayed or choppy audio	Weak Wi-Fi signal	Move camera closer to router or use a Wi-Fi extender. Check signal strength in app.
False sound alerts	High sensitivity or background noise	Lower sensitivity in Smart Alerts settings. Disable unnecessary sound detection.

One time, my Arlo Pro 4 kept triggering “baby cry” alerts—but we don’t have a baby. Turns out, my neighbor’s wind chime made a high-pitched jingle that the camera misinterpreted. After lowering the sensitivity and adding a “chime zone” exclusion, the false alerts stopped.

Final Thoughts: Should You Rely on Arlo Cameras for Sound?

So, can Arlo cameras hear sound? Absolutely—but with caveats. They’re not studio-quality microphones, nor are they designed for eavesdropping. Instead, they’re smart, context-aware audio tools that enhance your security, convenience, and peace of mind when used correctly.

For most users, Arlo’s audio features are a game-changer. Whether it’s hearing a package drop, calming a barking dog with two-way talk, or getting a real-time alert when a window breaks, sound adds a layer of awareness that video alone can’t provide. But it’s not perfect. Wind, distance, privacy laws, and false alerts mean you need to be smart about how you use it.

My advice? Start simple. Enable audio on one camera, test it in your environment, and adjust as needed. Use two-way audio for deliveries, sound alerts for emergencies, and disable the mic in sensitive areas. Over time, you’ll learn what works—and what doesn’t.

At the end of the day, Arlo cameras aren’t just about seeing the world. They’re about understanding it—and sound is a big part of that. Whether you’re protecting your home, checking on your kids, or just curious about what’s happening outside your door, knowing that your camera can hear makes all the difference.

So go ahead—turn on that mic, fine-tune your alerts, and listen in. Just remember: with great power comes great responsibility. Use your Arlo’s ears wisely, and you’ll get the most out of every beep, bark, and breaking glass it captures.
