Are Arlo HD and Arlo Pro Cameras Compatible? Everything You Need to Know

So you’ve been eyeing the Arlo HD and Arlo Pro cameras, maybe even picked up a couple already, and now you’re wondering: “Can I use them together?” Maybe you started with the Arlo HD, loved the idea of wireless home security, and now you’re considering upgrading to the Arlo Pro for better features. Or perhaps you’re building a system from scratch and want to mix and match based on your needs. Either way, you’re not alone in asking: Are Arlo HD and Arlo Pro cameras compatible?

Let’s cut to the chase: Yes, Arlo HD and Arlo Pro cameras are compatible—but with a few important caveats. It’s not as simple as “plug and play” across all features, and there are nuances that can trip up even seasoned smart home users. Think of it like using different generations of iPhones with the same iCloud account: they can coexist, but some apps or features might not work the same way. In this guide, we’ll walk through everything you need to know—from hardware and software compatibility to real-world setups, troubleshooting tips, and what to watch out for when mixing these two popular camera lines. Whether you’re a first-time buyer or a long-time Arlo user, this is your go-to resource.

Understanding the Arlo HD and Arlo Pro: Key Differences

Before we dive into compatibility, it’s essential to understand what sets the Arlo HD and Arlo Pro apart. Both are part of Netgear’s Arlo smart security ecosystem, but they were released years apart and target slightly different user needs. Knowing their differences helps explain why compatibility isn’t always seamless.

Release Timeline and Design Philosophy

The Arlo HD (often referred to as the original Arlo) launched in 2014 and was a game-changer for wireless, battery-powered security cameras. It offered 720p HD video, weather resistance, and easy DIY installation. At the time, it was revolutionary—no wires, no hubs, just cameras and a base station.

Fast forward to 2017: Netgear released the Arlo Pro, aiming to fix some of the HD’s limitations. The Pro introduced 1080p HD video, improved night vision (with color in some models), a built-in siren, better battery life, and a more robust base station (the Arlo SmartHub). The design was sleeker, and the mounting system was more flexible.

So, the Arlo Pro isn’t just a “newer” version—it’s an evolution with better hardware, firmware, and features. This generational gap is the root of many compatibility quirks.

Video Quality and Night Vision

• Arlo HD: 720p HD resolution. Night vision is black-and-white, using standard infrared LEDs.
• Arlo Pro: 1080p Full HD. Some models (like the Arlo Pro 2 and later) offer color night vision with a spotlight, giving you richer, more detailed footage in low light.

This difference means that while both cameras can stream to the same app, the Pro will deliver sharper, more vibrant footage—especially in darkness. If you’re mixing them, your viewing experience won’t be uniform, which might matter if you’re picky about image consistency.

Battery and Charging

Both use rechargeable lithium-ion batteries, but the Pro’s battery is larger and lasts longer (typically 4–6 months vs. 3–4 for the HD). The Arlo Pro also supports quick charging and optional solar panels, giving it a clear edge in long-term usability.

Here’s a real-life example: Sarah, a homeowner in Seattle, started with two Arlo HD cameras in 2016. When one died in 2019, she replaced it with an Arlo Pro. “I didn’t think much about compatibility,” she told me. “But I noticed the Pro lasted almost twice as long between charges. I ended up switching my other HD to a Pro too—just for peace of mind.”

Base Stations and Hubs: The Compatibility Engine

The base station (or SmartHub) is the heart of your Arlo system. It connects your cameras to your Wi-Fi network, stores footage (if you have a local backup), and manages communication. This is where compatibility gets interesting—and sometimes complicated.

Can You Use the Same Base Station for Both?

Yes, with limitations. The Arlo SmartHub (introduced with the Arlo Pro) can support both Arlo HD and Arlo Pro cameras. But the original Arlo base station (the white box from 2014–2016) cannot connect to Arlo Pro cameras.

• ✅ Arlo SmartHub: Compatible with Arlo HD, Arlo Pro, Arlo Pro 2, Arlo Pro 3, and Arlo Ultra.

<

• ❌ Original Arlo Base Station: Only supports Arlo HD and early Arlo Q models. No Arlo Pro support.

This is a crucial distinction. If you’re upgrading from HD to Pro, you’ll likely need to replace your old base station with the SmartHub. The good news? The SmartHub is backward compatible, so your existing HD cameras won’t become e-waste.

Setup Example: Mixing HD and Pro with a SmartHub

Let’s say you have:

• 2 Arlo HD cameras (original, 720p)
• 1 Arlo Pro (1080p with spotlight)
• 1 Arlo SmartHub (purchased separately)

Here’s how to set it up:

1. Plug in the SmartHub and connect it to your Wi-Fi using the Arlo app.
2. In the app, tap “Add Camera” and follow the on-screen instructions.
3. For each Arlo HD, press the sync button on the camera, then on the hub. Wait for the blue light to blink.
4. Repeat for the Arlo Pro. The app will recognize it as a newer model and enable its advanced features (like siren, 1080p, etc.).
5. Once all are added, you’ll see them in one unified view in the app.

Pro tip: Name your cameras clearly (e.g., “Front Door – HD,” “Backyard – Pro”) so you know which is which when reviewing footage.

What Happens If You Don’t Upgrade the Hub?

If you try to pair an Arlo Pro with the original base station, it simply won’t connect. The app will show an error like “Camera not supported.” You’ll need to either:

• Upgrade to the SmartHub (recommended), or
• Use the Arlo Pro with its own standalone SmartHub (if you bought one).

Some users try to avoid the cost of a new hub, but trust me—it’s worth it. The SmartHub improves signal range, reduces Wi-Fi interference, and enables local storage (a privacy win).

Software and App Integration: One Ecosystem, Multiple Devices

The Arlo app is where your cameras come to life. Whether you’re using Arlo HD or Arlo Pro, they both connect to the Arlo Secure app (formerly Arlo app), which unifies your entire system. But “unified” doesn’t always mean “equal.”

Unified Dashboard and Alerts

Once both camera types are added to the same account, they appear in one dashboard. You can:

• View live feeds from all cameras on one screen.
• Receive motion alerts for any camera (customizable by zone and sensitivity).
• Review recorded clips in the timeline or event history.

For example, Mark in Austin uses one Arlo HD for his porch and two Arlo Pro 2s for his backyard. “I get a single notification when motion is detected anywhere,” he said. “The app shows me which camera triggered it, so I can respond fast.”

Feature Gaps and Limitations

Here’s where things get tricky. While the app supports both, not all features are available on both models. For instance:

• Arlo Pro can use the built-in siren, two-way audio, and 1080p streaming—all accessible in the app.
• Arlo HD lacks the siren and only streams 720p. Two-way audio is available, but the mic quality is weaker.

Also, newer features like AI-powered object detection (e.g., “Person,” “Vehicle,” “Animal”) are only available on Arlo Pro and later models. Your Arlo HD will still detect motion, but it can’t distinguish between a squirrel and a stranger.

This means your alerts might be less precise with HD cameras. You’ll get more false positives (like leaves blowing), which can be annoying if you’re relying on smart notifications.

Firmware Updates and Support

Arlo rolls out firmware updates through the app. Both HD and Pro cameras receive updates, but the HD line is nearing “end of life” in terms of major feature additions. You’ll still get security patches, but don’t expect new AI features or performance boosts.

Tip: Check your camera’s firmware regularly. In the app, go to Settings > Camera Info > Firmware Version. If it’s outdated, tap “Update.” Keeping both models updated ensures compatibility and security.

Storage, Cloud Plans, and Local Options

How you store and access your footage depends on your Arlo plan—and here, compatibility is mostly seamless, but with some nuances.

Cloud Storage: Arlo Secure Plans

Arlo offers cloud plans that work across all camera types. For example:

• Arlo Secure (Essential): 30-day video history, 24/7 emergency response, AI detection (on compatible cameras).
• Arlo Secure Plus: All features + 24/7 professional monitoring.

The key point: You can mix HD and Pro cameras under the same plan. However, AI detection (person/vehicle alerts) only works on Pro and newer models. Your HD cameras will still record to the cloud, but you won’t get smart alerts from them unless you’re on a plan that includes it—and even then, the HD won’t support it.

Example: You have a $10/month plan for 3 cameras (2 Pro, 1 HD). You’ll get AI detection on the Pro cameras, but the HD will only have basic motion alerts.

Local Storage with the SmartHub

The SmartHub supports microSD card storage (up to 2TB). This is a huge privacy and cost-saving feature—no cloud fees, no data in the cloud.

• Both Arlo HD and Arlo Pro can record to the same microSD card.
• Footage is stored locally and can be accessed via the app or by removing the card.
• You can set recording rules (e.g., “Only record when motion is detected”).

But there’s a catch: The SmartHub prioritizes newer cameras for AI features. If you have both HD and Pro on local storage, the Pro will use AI to filter clips (e.g., “Show me only person alerts”), while the HD will only use basic motion detection. This can make local playback less efficient if you have many HD clips.

Cost Comparison: Cloud vs. Local

Storage Option	Cost (3 Cameras)	AI Detection	Best For
Cloud (Arlo Secure)	$9.99–$19.99/month	Pro only	Users who want smart alerts and off-site backup
Local (SmartHub + microSD)	One-time: ~$50–$100 (hub + card)	Pro only	Users who want privacy and no monthly fees
Cloud + Local (Hybrid)	Cloud fee + one-time hardware	Pro only	Best of both worlds: local backup + cloud access

For most users, the hybrid approach (cloud + local) is ideal. You get AI-powered alerts and off-site access, plus local storage as a backup.

Real-World Tips for Mixing Arlo HD and Arlo Pro

Now that we’ve covered the technical side, let’s talk about practical advice. Mixing these cameras isn’t just possible—it can be a smart strategy if done right.

When It Makes Sense to Mix

Here are a few scenarios where combining HD and Pro works well:

• Gradual upgrades: You’re not ready to replace all cameras at once. Keep your HD for less critical areas (like a side yard) and use Pro for high-traffic zones (front door, garage).
• Budget constraints: Arlo Pro costs more. Use HD for basic monitoring and Pro where you need better image quality or AI.
• Legacy systems: You have working HD cameras and don’t want to waste them.

Example: Emily in Denver kept her two Arlo HDs for the driveway and backyard shed. She added an Arlo Pro 3 for her front porch. “The Pro is way better for seeing faces at night,” she said. “But the HDs are still fine for checking if the dog got out.”

Common Pitfalls and How to Avoid Them

• Pitfall: Using the old base station with a Pro camera.
  Solution: Always use the SmartHub for mixed setups.
• Pitfall: Expecting AI alerts from HD cameras.
  Solution: Use Pro cameras for zones where smart detection matters (e.g., front door).
• Pitfall: Inconsistent battery life.
  Solution: Check battery levels weekly in the app. Replace HD batteries more often.
• Pitfall: Confusing camera feeds in the app.
  Solution: Rename cameras with location + model (e.g., “Kitchen – Pro”).

Pro Tips for Better Performance

• Place the SmartHub centrally to ensure strong signal for all cameras, especially if they’re far apart.
• Use the “Activity Zones” feature in the app to reduce false alerts. HD cameras benefit from this too, even without AI.
• Consider a Wi-Fi extender if you have cameras in a detached garage or far corner of the yard.
• Label your batteries so you know which are for HD vs. Pro (they’re not interchangeable).

Final Thoughts: Is Mixing Arlo HD and Arlo Pro Worth It?

So, are Arlo HD and Arlo Pro cameras compatible? Absolutely—but with a smart strategy. They can live together in the same system, share the same app, and even the same SmartHub. But compatibility isn’t a free pass to ignore their differences.

The Arlo Pro is objectively better: higher resolution, longer battery life, AI detection, and a siren. The Arlo HD is still functional, especially for basic monitoring, but it’s showing its age. Mixing them is like using a flip phone and a smartphone on the same plan—they work, but one does a lot more.

For most users, the best approach is:

• Use the Arlo SmartHub as your base.
• Keep HD cameras in low-priority areas (e.g., side yards, sheds).
• Use Pro cameras in high-priority zones (front door, garage, backyard).
• Choose a storage plan that matches your privacy and budget needs.

And remember: Arlo’s ecosystem is designed to evolve. If you started with HD, you’re not locked in. You can upgrade one camera at a time, keep your investment, and still enjoy the benefits of modern smart home tech.

At the end of the day, compatibility isn’t just about hardware—it’s about how you use it. Whether you’re mixing HD and Pro or planning a full Pro upgrade, the goal is the same: peace of mind, better security, and a system that works for you. So go ahead—build your hybrid setup. Just do it with your eyes open, and you’ll get the best of both worlds.
