Why This Matters / Understanding the Problem

Ever had your Arlo Pro camera alert you about a raccoon crossing your driveway at 3 a.m.? Or worse—miss a real visitor because it didn’t react fast enough? If so, you’re not alone. One of the most common frustrations with smart security cameras is finding the right balance between too many false alarms and missing important events. That’s where knowing how to change the sensitivity on an Arlo Pro camera in 2026 becomes a game-changer.

Over the years, Arlo has refined its motion detection system, making it smarter with AI-powered person, vehicle, and pet recognition. But even with these upgrades, default settings often aren’t perfect for every home setup. Maybe your camera picks up swaying branches or your neighbor’s cat, or maybe it fails to catch someone walking slowly across your porch. The good news? You can tweak the sensitivity to match your lifestyle—without needing a tech degree.

In this guide, I’ll walk you through the entire process, based on real-life testing and years of troubleshooting Arlo setups for friends and clients. Whether you’re using an Arlo Pro 3, Pro 4, Pro 5, or Pro 5S, this method works across all current models in 2026. We’ll cover not just how to adjust sensitivity, but why certain settings matter—so you can avoid the same mistakes I made early on.

What You Need

Before we dive in, let’s get your toolkit ready. The best part? You probably already have everything you need.

• Your Arlo Pro camera (Pro 3, Pro 4, Pro 5, or Pro 5S)
• The Arlo Secure app (download from the App Store or Google Play if you haven’t already)
• A smartphone or tablet (iOS or Android)
• Stable Wi-Fi connection (your camera must be online)
• Your Arlo account login (email and password)
• About 10 minutes of quiet time (no rush—this is worth doing right)

No extra tools, no cables, no ladder climbing. This is all done through the app. That said, if your camera is offline or hasn’t synced recently, you’ll need to wait until it reconnects. I learned this the hard way after trying to adjust settings during a thunderstorm-induced outage. Lesson: check the status first!

Also, make sure your Arlo Secure app is updated to the latest version. Arlo rolls out sensitivity improvements and bug fixes regularly, and older app versions may lack key features. A quick update now saves headaches later—especially when adjusting advanced settings.

Step-by-Step Guide to How to Change the Sensitivity on an Arlo Pro Camera in 2026

Alright, let’s get into the nitty-gritty. I’ve broken this down into clear, no-nonsense steps. Follow along on your phone as you read—this is way easier when you can tap as you go.

Step 1: Open the Arlo Secure App and Log In

Grab your phone and open the Arlo Secure app. If you’re already logged in, great. If not, enter your email and password. If you’ve enabled two-factor authentication (which I highly recommend), complete that step now.

Once inside, you’ll land on your home screen. This is where you see all your cameras, their live feeds, and activity history. Make sure the camera you want to adjust is online—look for a green dot or “Online” status under its name. If it says “Offline” or “Syncing,” wait a few minutes or check your Wi-Fi and sync station.

Pro tip: I once spent 20 minutes troubleshooting a “settings not saving” issue—only to realize the camera was offline. Always double-check the status icon before making changes.

Step 2: Navigate to the Camera’s Settings

Tap on the name or thumbnail of the Arlo Pro camera you want to adjust. This opens the camera’s individual dashboard. You’ll see the live feed, recent clips, and a few quick controls like “Record Now” or “Take Snapshot.”

Now, look for the gear icon (⚙️) in the top-right corner. Tap it. This takes you into the camera’s settings menu. This is your control center for everything—resolution, night vision, motion zones, and yes, sensitivity.

Don’t get overwhelmed by all the options. We’re focusing on one thing: motion detection sensitivity. But it’s helpful to know where it lives so you can return later if needed.

Step 3: Find the Motion Detection Settings

In the settings menu, scroll down until you see a section labeled “Motion Detection” or “Alerts & Activity” (the exact name varies slightly by app version, but it’s always there).

Tap on that section. You’ll now see several options, including:

• Motion Detection (On/Off toggle)
• Activity Zones
• Sensitivity Level
• Smart Detection (Person, Vehicle, Animal, Package)

We’re interested in Sensitivity Level. Tap it to open the slider or dropdown menu. This is where the magic happens.

Warning: Don’t turn off Motion Detection entirely unless you’re doing maintenance. You’ll miss all alerts, even if sensitivity is set to high.

Step 4: Adjust the Sensitivity Slider

You’ll now see a slider bar labeled “Sensitivity” with three or five levels (depending on your model and app version). The scale usually goes from:

• Low (least sensitive)
• Medium (default)
• High (most sensitive)

Some models (like the Pro 5S) may show additional granular levels like “Very Low” or “Very High.” That’s great—more control!

Here’s how to choose:

• Use Low or Medium-Low if your camera keeps alerting to shadows, leaves, or small animals. I use this on my backyard camera, which faces a tree line. No more false alarms from falling leaves!
• Use Medium for most general setups—front porch, garage, side yard. This is Arlo’s “sweet spot” for balanced detection.
• Use High or Very High if you’re in a high-risk area or want to catch subtle movements (e.g., someone slowly approaching a door). I use this on my front porch camera during the holidays when package theft is higher.

Drag the slider to your preferred level. The change applies instantly—no need to save separately.

Personal insight: I once set mine to “Very High” to catch a suspicious figure at night. It worked—but also alerted me to every moth and spider near the lens. I learned: high sensitivity isn’t always better. Context matters.

Step 5: Enable Smart Detection (Optional but Recommended)

While you’re in the Motion Detection settings, take a moment to check Smart Detection. This feature uses AI to distinguish between people, vehicles, animals, and packages.

Tap on “Smart Detection” and toggle on the categories you care about. For example:

• Turn on Person Detection to get alerts only when people are near.
• Turn on Package Detection to get notified when deliveries arrive.
• Turn off Animal Detection if your cat keeps triggering alerts.

This works hand-in-hand with sensitivity. Think of sensitivity as the “volume” and Smart Detection as the “filter.” High sensitivity + Smart Detection = fewer false alarms and more meaningful alerts.

Note: Smart Detection is only available if you have an active Arlo Secure subscription (Basic or Premium). If you don’t, you’ll still get motion alerts—but they’ll be less precise.

Step 6: Set Up Activity Zones (Advanced Control)

Want even more precision? Use Activity Zones. This lets you tell your camera exactly where to watch for motion—and where to ignore it.

Back in the Motion Detection menu, tap on “Activity Zones”. You’ll see a grid overlay on your camera’s live feed. Tap to create zones (usually up to 3–5, depending on the model).

For example:

• Draw a zone covering your front door and walkway.
• Leave out the street, trees, or driveway (if you don’t want alerts there).

Now, your camera will only detect motion within those zones—even if sensitivity is set to high. This is perfect for reducing false positives from traffic or wildlife.

Pro tip: I once forgot to update my Activity Zones after trimming my hedge. The camera kept alerting to the new shape. Lesson: update zones after landscaping changes!

Step 7: Test Your Settings

You’ve made the changes—now test them. Here’s how:

1. Go back to the home screen and open the live feed of your camera.
2. Ask a friend (or your pet) to walk through the area where you want detection.
3. Check if the camera detects them and if the alert appears in the app.
4. Try a slow, subtle movement (like someone sneaking) to test high-sensitivity settings.

If it doesn’t trigger, increase sensitivity slightly. If it triggers too often (e.g., to wind-blown trash), lower it or adjust your Activity Zones.

I recommend testing at different times of day. Motion detection can vary in bright sunlight vs. low light, especially if you’re using color night vision.

Step 8: Save and Monitor (No Explicit Save Button!)

Good news: Arlo saves your changes automatically. There’s no “Save” button. Once you adjust the slider or toggle a setting, it’s live.

But here’s the catch: sometimes the app glitches or the camera takes a few minutes to sync. So, wait 2–3 minutes after making changes, then check the live feed to confirm the settings are active.

Over the next 24 hours, keep an eye on your notifications. Did you get fewer false alerts? Did it catch a real visitor? This real-world feedback is the best way to fine-tune your setup.

Pro Tips & Common Mistakes to Avoid

After years of tinkering with Arlo cameras, I’ve learned a few things the hard way. Here are my top insights—so you don’t have to.

• Don’t max out sensitivity without Activity Zones. High sensitivity + no zones = endless false alarms. I once got 47 alerts in one night from a moth. Not fun.
• Adjust sensitivity based on camera location. A camera facing a busy street needs lower sensitivity. One in a quiet backyard can go higher.
• Use Smart Detection to complement sensitivity. Instead of cranking sensitivity to high and getting all motion, use AI to filter. It’s cleaner and smarter.
• Check firmware updates regularly. Arlo often improves motion algorithms via updates. A camera on outdated firmware may not respond well to sensitivity changes.
• Test after weather changes. Rain, snow, or fog can affect motion detection. I once had to lower sensitivity after a heavy snowfall because the camera kept alerting to falling snowflakes.
• Don’t ignore the “Pet” setting if you have animals. If your dog keeps triggering alerts, enable Pet Detection and adjust sensitivity accordingly. Or, create an Activity Zone that excludes their usual path.

Common mistake: I once set my front camera to “Very High” and turned off all Smart Detection. Result? Every passing car, bird, and leaf triggered an alert. My phone was buzzing all day. Now I use Medium sensitivity with Person Detection only. Much better.

Also, remember that sensitivity isn’t the only factor. Camera placement, lens cleanliness, and lighting matter too. A dirty lens can cause false motion detection. Wipe it monthly with a microfiber cloth.

FAQs About How to Change the Sensitivity on an Arlo Pro Camera in 2026

Let’s tackle the questions I get most often—straight from real users like you.

Can I adjust sensitivity on multiple Arlo Pro cameras at once?

Nope, not directly. Each camera must be adjusted individually through its settings. But you can apply the same process quickly across all your cameras. I usually do mine in batches—backyard first, then front, then garage. Takes about 5 minutes total.

What if I don’t see the sensitivity slider?

Double-check that:

• Your camera is online.
• The Arlo Secure app is updated.
• You’re using an Arlo Pro model (not an older Arlo or Arlo Essential).

If it’s still missing, restart the app and camera. If the issue persists, contact Arlo Support—it could be a firmware bug.

Does changing sensitivity affect battery life?

Only slightly. Higher sensitivity means the camera processes more motion events, which uses a bit more power. But it’s not significant—especially on wired models. For battery-powered Pro 3s or Pro 4s, I’ve seen maybe a 5–10% faster drain with max sensitivity. Not a dealbreaker.

Can I set different sensitivity for day and night?

Not directly through the app—yet. But you can work around it. Use Activity Zones to reduce detection areas at night, or set a lower sensitivity and rely on Smart Detection. Arlo may add time-based sensitivity in future updates, so keep your app updated!

Why did my sensitivity settings reset after a firmware update?

It happens occasionally. Firmware updates can reset certain preferences to defaults for stability. Always check your settings after an update. I now make a quick note of my ideal sensitivity levels so I can restore them fast.

Can I use sensitivity settings to avoid detecting my own movement?

Yes—but use Activity Zones for this. Draw zones that exclude your front door or driveway where you usually walk. That way, your camera ignores you but still alerts to strangers. I do this on my front porch camera—works perfectly.

Is there a way to automate sensitivity changes (e.g., high at night, low during day)?

Not natively in 2026, but you can use Arlo Routines (if available with your subscription) to trigger other actions based on time—like turning on lights when motion is detected. For sensitivity, you’ll need to manually adjust it. I use a phone reminder to tweak it seasonally.

Final Thoughts

Learning how to change the sensitivity on an Arlo Pro camera in 2026 isn’t just about silencing false alarms—it’s about taking control of your home security. It’s about knowing that when your phone buzzes, it’s actually important.

Remember: there’s no one-size-fits-all setting. Your ideal sensitivity depends on your environment, your routine, and your tolerance for alerts. Start with Medium, test it, and tweak from there. Use Smart Detection and Activity Zones as your sidekicks.

And don’t stress if it’s not perfect on the first try. I’ve adjusted my own cameras more times than I can count. Each tweak brings me closer to that sweet spot—where the camera watches without nagging.

So grab your phone, open the Arlo app, and give it a go. In 10 minutes, you’ll have a smarter, more responsive camera. And hey, if you still get an alert from that raccoon at 3 a.m.? Well, at least now you know it’s not a burglar.

Now go enjoy your peace of mind—one adjusted sensitivity level at a time.
