Why Your Arlo Camera Might Be Too Sensitive (And Why That’s a Problem)

Let’s be honest—there’s nothing more frustrating than getting constant notifications from your Arlo camera every time a leaf blows by or your neighbor’s cat saunters past. You installed the camera for peace of mind, not to be bombarded with false alarms. I remember when I first set up my Arlo Pro 4. I was so excited to finally have a smart home security system, but within hours, my phone was buzzing nonstop. A shadow? Motion alert. A passing car? Motion alert. Even my own shadow walking by the window? You guessed it—motion alert. It felt like I was being watched… by my own camera!

If you’ve ever found yourself muttering, “How do I decrease the sensitivity on my Arlo camera?” you’re not alone. Many Arlo users face this issue, especially if their camera is placed in high-traffic outdoor areas or near trees, bushes, or busy sidewalks. The good news? It’s fixable. With a few simple adjustments, you can fine-tune your Arlo camera to ignore the noise and focus on real threats. In this post, I’ll walk you through everything you need to know—from understanding how sensitivity works to step-by-step instructions for adjusting it on different Arlo models.

Understanding Motion Sensitivity on Arlo Cameras

What Does “Sensitivity” Mean on an Arlo Camera?

When we talk about sensitivity on an Arlo camera, we’re referring to how easily the camera detects motion. Think of it like your ears in a quiet room versus a loud concert. In a quiet room, even a whisper is noticeable (high sensitivity). In a loud concert, only the loudest sounds stand out (low sensitivity). Arlo cameras use a combination of infrared (IR) motion sensors and video analytics to detect movement. The sensitivity setting determines how much motion—or how subtle a movement—triggers an alert.

High sensitivity means the camera picks up even the smallest movements, like a falling leaf or a passing bird. Low sensitivity means it only reacts to larger, more significant motion, like a person walking up to your door or a car pulling into your driveway. The goal is to find the sweet spot: sensitive enough to catch real threats, but not so sensitive that your phone becomes a notification nightmare.

Why Too Much Sensitivity Causes False Alarms

False alarms are the number one complaint among Arlo users, and sensitivity is often the culprit. Here’s why:

• Outdoor elements: Wind, rain, snow, and moving vegetation can trigger motion alerts. A swaying tree branch? That’s enough to set off a high-sensitivity camera.

<

• Light changes: Shadows, sunlight flickering through leaves, or headlights at night can mimic motion and trigger alerts.
• Small animals: Squirrels, raccoons, and even birds can trip the motion sensor, especially if they’re close to the camera.
• Reflections: Windows, shiny surfaces, or puddles can reflect movement, causing the camera to think something’s there.

For example, my Arlo camera was mounted under an overhang, right near a maple tree. Every time the wind blew, the leaves would dance, and boom—three or four alerts in a row. I felt like I was in a security surveillance movie, but instead of catching a thief, I was watching leaves twirl. That’s when I knew I had to learn how to decrease the sensitivity on my Arlo camera.

Step-by-Step Guide to Decreasing Sensitivity on Arlo Cameras

Adjusting Sensitivity via the Arlo App (All Models)

The easiest and most reliable way to reduce sensitivity is through the Arlo app. This method works for all Arlo models, including Arlo Pro, Ultra, Essential, and Q series. Here’s how to do it:

1. Open the Arlo app on your smartphone or tablet.
2. Tap on the camera you want to adjust.
3. Go to Settings (usually a gear icon).
4. Select Motion Detection or Activity Zones & Motion Sensitivity.
5. You’ll see a slider labeled Motion Sensitivity. Drag it to the left to decrease sensitivity (toward “Low”).
6. For finer control, tap on Activity Zones to define where motion should be detected (more on this later).
7. Tap Save or Done.

Pro tip: Start by reducing sensitivity to 50% and test it for 24 hours. If you’re still getting false alerts, reduce it further. If you’re missing real motion (like a delivery person), increase it slightly. It’s all about finding the right balance.

Using Activity Zones to Fine-Tune Detection

Activity zones are a game-changer. Instead of letting your camera detect motion across its entire field of view, you can draw zones where motion should (or shouldn’t) trigger alerts. This is perfect for ignoring trees, sidewalks, or busy streets while still monitoring your front door or driveway.

Here’s how to set up activity zones:

• In the Arlo app, go to the camera’s settings.
• Tap Activity Zones.
• Tap Add Zone and drag the corners to cover the area you want to monitor (e.g., your front porch).
• To ignore an area (like a tree), tap Add Zone and select Exclude. Draw the zone over the tree.
• You can have up to three zones per camera (on most models).

For example, I excluded the tree branch and the sidewalk in front of my house. Now, the camera only alerts me when someone walks up to my door. No more leaf alerts!

Adjusting Sensitivity for Arlo Doorbell and Indoor Cameras

Arlo doorbells and indoor cameras also have sensitivity settings, but the process is slightly different. For Arlo doorbells:

• Open the Arlo app.
• Tap the doorbell.
• Go to Settings > Video & Audio > Motion Detection Sensitivity.
• Adjust the slider to lower sensitivity.

For indoor cameras, the process is the same as outdoor models, but you may need to consider:

• Pet detection: If you have pets, enable Pet Detection (if available) to ignore small animals.
• Night vision: In low light, sensitivity can behave differently. Test adjustments during both day and night.

Advanced Tips to Reduce False Alarms (Beyond Sensitivity)

Optimize Camera Placement and Angle

Sometimes, the best way to reduce false alerts isn’t adjusting sensitivity—it’s changing where your camera points. Here are a few placement tips:

• Avoid pointing at moving objects: Don’t aim at trees, bushes, or busy streets. Even with low sensitivity, constant motion can still trigger alerts.
• Mount at a higher angle: A 7–10 foot mounting height reduces the chance of small animals or passing shadows triggering the sensor.
• Use a wall or eave mount: This helps stabilize the camera and reduces vibrations from wind or nearby movement.
• Avoid glass surfaces: If you’re using an indoor camera, don’t point it at a window. Reflections and glare can cause false alerts.

I once had an Arlo camera pointing straight at a bush. Even at 30% sensitivity, it was still alerting me every time a leaf moved. After repositioning it to focus only on my front walkway, the alerts dropped by 80%. It was a simple fix, but it made a huge difference.

Leverage Smart Alerts and AI Features

Newer Arlo models (like Arlo Pro 4, Ultra, and Essential) come with AI-powered features that can help reduce false alarms:

• Person Detection: Only alerts when a human is detected, ignoring animals, vehicles, or shadows.
• Vehicle Detection: Alerts only for cars, not people or animals.
• Package Detection: Alerts when a package is delivered (great for porch pirates).
• Custom Alerts: Set up rules like “Alert only between 9 PM and 6 AM” or “Only alert if motion lasts more than 5 seconds.”

To enable these, go to Settings > Smart Alerts and toggle on the features you want. For example, I enabled Person Detection and Vehicle Detection. Now, my camera ignores squirrels and passing cars but still alerts me when someone approaches my door.

Schedule Sensitivity Based on Time of Day

Different times of day call for different sensitivity levels. For example:

• Daytime: Lower sensitivity (to ignore wind-blown leaves and shadows).
• Nighttime: Higher sensitivity (to catch intruders, but use Person Detection to avoid false alerts from insects or headlights).

While Arlo doesn’t have built-in time-based sensitivity scheduling, you can simulate it using modes. Here’s how:

1. Create two modes: Day Mode (low sensitivity) and Night Mode (high sensitivity + Person Detection).
2. Set up a schedule in Settings > Modes & Rules to switch automatically at sunrise/sunset.

This way, your camera adapts to the environment without you lifting a finger.

Comparing Sensitivity Settings Across Arlo Models

Not all Arlo cameras handle sensitivity the same way. Here’s a quick comparison of how different models let you adjust sensitivity and manage false alerts:

Arlo Model	Sensitivity Range	Activity Zones	AI Features	Best For
Arlo Pro 4	1–100% (slider)	3 zones (include/exclude)	Person, Vehicle, Pet Detection	Outdoor security with minimal false alerts
Arlo Ultra	1–100% (slider)	3 zones (include/exclude)	Person, Vehicle, Package, Pet Detection	High-end outdoor monitoring with AI precision
Arlo Essential	1–100% (slider)	1 zone (include only)	Person Detection	Budget-friendly outdoor/indoor use
Arlo Q	1–100% (slider)	No activity zones	No AI features	Indoor monitoring (manual sensitivity only)
Arlo Doorbell	1–100% (slider)	No activity zones	Person Detection	Porch monitoring with reduced animal alerts

As you can see, newer models offer more advanced tools to fine-tune sensitivity. If you’re using an older model like the Arlo Q, you’ll rely more on manual adjustments and smart placement. But even with basic features, you can still significantly reduce false alerts with the right approach.

When to Contact Arlo Support (And What to Expect)

Signs Your Sensitivity Issue Might Be a Hardware Problem

Sometimes, no matter how much you adjust sensitivity, false alerts persist. This could indicate a hardware or firmware issue. Look for these red flags:

• Alerts with no visible motion: If the camera triggers alerts but you see nothing in the video, the sensor might be faulty.
• Consistent false alerts in one area: Even after excluding activity zones, the same spot keeps triggering.
• Camera overheating: Excessive heat can cause sensors to malfunction. Check if the camera is in direct sunlight for long periods.
• Firmware bugs: Older firmware versions may have known sensitivity bugs. Check for updates in the Arlo app.

How to Get Help from Arlo Support

If you’ve tried everything and still can’t reduce false alerts, it’s time to contact Arlo support. Here’s how:

• In-app chat: Go to Settings > Help & Support and start a chat with a support agent.
• Phone support: Call Arlo’s customer service (available in select regions).
• Community forums: The Arlo Community is full of users sharing tips and workarounds.

When you contact support, be ready to provide:

• Your camera model and firmware version.
• Screenshots of your sensitivity and activity zone settings.
