Do You Have to Scan Arlo Cameras for Setup and Security

Let’s be honest—setting up a new security system can feel like trying to assemble furniture without the instruction manual. You’ve got all these parts, a vague idea of how they *should* work, and a growing sense of dread as you stare at your phone screen. If you’ve recently bought an Arlo camera—whether it’s the sleek Arlo Pro 5S, the budget-friendly Arlo Essential, or even the floodlight version—you might be wondering: Do you have to scan Arlo cameras during setup? And why does it matter for your home’s security?

When I first unboxed my Arlo Pro 4, I was excited. I’d read the reviews, watched the setup videos, and even cleared space on my Wi-Fi network. But when the app prompted me to “scan the QR code,” I paused. Was this just a formality? Could I skip it and pair the camera manually? Spoiler: I tried skipping it. It didn’t end well. My camera blinked red, the app froze, and I spent 20 minutes troubleshooting before I finally scanned the code. That moment taught me something important: scanning isn’t just a box to check—it’s the backbone of a secure, reliable setup. In this guide, we’ll break down exactly why scanning Arlo cameras matters, how it works, and what happens if you don’t do it. Whether you’re a tech newbie or a seasoned DIYer, this is the real talk you need before your next install.

Why Scanning Arlo Cameras Is a Critical First Step

The Science Behind QR Code Pairing

You’ve probably scanned QR codes at coffee shops, concert tickets, or even to pay a friend. But Arlo’s QR code isn’t just a shortcut—it’s a security handshake. Each Arlo camera has a unique QR code printed on the device (usually on the back or under the battery cover) or on its packaging. When you scan it with the Arlo app, you’re not just telling the app “this is my camera.” You’re transferring a bundle of encrypted data: the camera’s serial number, firmware version, and a one-time authentication token.

Here’s how it works in plain terms: Think of the QR code as a digital key. The app “unlocks” the camera’s identity, verifies it matches Arlo’s database, and then establishes a secure, encrypted link between your phone, the camera, and Arlo’s cloud servers. This prevents someone from intercepting your setup or pairing a stolen camera to your account. Without this scan, the camera remains “anonymous”—like a guest at a party with no name tag. It can’t join your network, and worse, it’s vulnerable to tampering.

What Happens If You Skip the Scan?

Let’s say you try to pair your Arlo camera manually (yes, the app lets you do this in some cases). You enter the serial number, select your Wi-Fi, and hit “connect.” Sounds easy, right? But here’s the catch: manual pairing bypasses critical security checks. For example:

• No firmware validation: The app can’t verify if the camera’s software is up-to-date. Outdated firmware is a hacker’s dream—it might have unpatched vulnerabilities.
• No anti-spoofing: Scanning confirms the camera is genuine. Manual entry could let a counterfeit or compromised device into your network.
• Wi-Fi connection issues: The QR code often includes Wi-Fi credentials (if saved during setup). Without it, you’re more likely to mistype your password or select the wrong network band (2.4GHz vs. 5GHz).

I learned this the hard way when my neighbor’s kid tried to “help” by manually pairing his old Arlo camera to my account. The camera connected, but it had outdated firmware and started spamming my phone with false motion alerts. Scanning would’ve flagged the issue instantly.

Step-by-Step: How to Scan Arlo Cameras Correctly

Preparing Your Camera and App

Before you scan, make sure you’re set up for success. Here’s what I do every time:

• Charge the camera fully: A low battery can interrupt the pairing process. I always charge mine to 100% before setup.
• Update the Arlo app: Open your app store and check for updates. An outdated app might not recognize newer camera models.
• Enable camera permissions: Go to your phone’s settings and grant the Arlo app access to your camera. (Yes, you need to let the app take a photo of the QR code.)
• Clear your workspace: Remove glare from lights or windows. I once spent 10 minutes scanning a QR code on my kitchen counter—until I realized the overhead light was creating a reflection.

Scanning the QR Code: A Visual Guide

The actual scan is simple, but a few hiccups are common. Here’s how to avoid them:

1. Open the Arlo app and tap “Add Device.” Select your camera model (e.g., “Arlo Pro 5S”).
2. Tap “Scan QR Code.” The app will activate your phone’s camera.
3. Hold your phone 6–12 inches from the QR code. Angle it slightly if needed. If the app doesn’t recognize it, try:
   • Adjusting the distance (too close or too far can confuse the scanner).
   • Moving to a brighter area (but avoid direct sunlight).
   • Wiping the QR code with a microfiber cloth (dust or smudges can block the scan).
4. Wait for the confirmation tone. The app will beep and show a checkmark. If it fails, tap “Try Again” or “Enter Serial Number Manually” (but see the risks above).

Pro Tip: If you’re setting up multiple cameras, scan them one at a time. The app can get confused if multiple QR codes are in view.

Troubleshooting Failed Scans

Even with perfect conditions, scans fail. Here are fixes I’ve used:

• “QR Code Not Recognized” error: The code might be damaged. Check the camera body—sometimes the print is smudged. If it’s on the packaging, try scanning the box instead.
• App crashes during scan: Force-close the app, restart your phone, and try again. I once had this happen after a software update—rebooting fixed it.
• “Camera Already Registered” message: The camera might have been used before. Contact Arlo support to “reset” it to factory settings.

Scanning vs. Manual Setup: Security and Performance Trade-Offs

Security: Why Scanning Is Non-Negotiable

Arlo’s QR code system is designed to prevent a type of attack called “device spoofing.” Imagine a hacker buys a used Arlo camera, wipes it, and tries to pair it to your account by guessing the serial number. Without scanning, they could succeed. But with scanning, the app checks the QR code’s embedded data against Arlo’s database. If the camera was reported lost/stolen or has a mismatched firmware signature, pairing fails.

Arlo also uses the scan to activate two-factor authentication (2FA) for your account. When you scan, the app sends a one-time code to your phone and email. This stops someone from accessing your account even if they steal your password. Manual setup skips this step—making your system less secure.

Performance: Faster, Fewer Headaches

Scanning isn’t just about security—it’s about efficiency. Here’s what I’ve noticed:

• Faster Wi-Fi pairing: The QR code often includes your Wi-Fi password (if saved). Manual setup requires typing it in—risking typos.
• Automatic firmware updates: Scanned cameras get the latest software during setup. Manual setup might leave you with an outdated camera.
• Better cloud sync: Scanned cameras connect directly to Arlo’s servers. Manual setup can create sync delays, especially if your internet is slow.

For example, my Arlo Essential Spotlight took 2 minutes to set up with scanning. When I tried manual setup on a friend’s camera, it took 15 minutes—and they still had to re-enter their Wi-Fi password three times.

Advanced Scenarios: When Scanning Isn’t Straightforward

Setting Up Multiple Cameras or a Base Station

Got a multi-camera system? The process changes slightly:

• With a base station (e.g., Arlo Pro 3 with SmartHub): Scan the base station’s QR code first. Then, pair each camera to the base station via the app (no QR code needed for cameras).
• Without a base station (wireless cameras): Scan each camera’s QR code individually. The app will guide you through naming them (e.g., “Front Door,” “Backyard”).

Pro Tip: Label your cameras with masking tape before scanning. It’ll save you from renaming them later. (I once named all my cameras “Camera 1,” “Camera 2,” etc.—and spent weeks fixing it.)

Replacing or Resetting a Camera

If you’re swapping a broken camera or resetting one to factory settings, scanning is still required—but the steps differ:

1. Reset the old camera: Press and hold the sync button for 10 seconds until the LED flashes amber.
2. Remove it from your account: In the app, go to Settings > My Devices > select the camera > Remove Device.
3. Scan the new camera’s QR code: The app will treat it as a fresh device.

Note: If you’re replacing a camera under warranty, Arlo support can sometimes transfer the old camera’s settings to the new one—but scanning is still mandatory.

Using Arlo with Third-Party Integrations

Want to connect Arlo to Google Home, Alexa, or HomeKit? Scanning is the first step. After pairing your camera via QR code, go to the app’s Integrations tab. For example:

• Alexa: Link your Arlo account in the Alexa app. The scanned cameras will appear as “Arlo devices.”
• HomeKit: Use the Arlo Secure app (not the standard Arlo app). Scanning is still required, but you’ll also need to enter a HomeKit code (found on the camera or packaging).
