How Many Cameras Can an Arlo Base Station Support? The Real Answer

Imagine this: You’ve just installed your first Arlo security camera. It’s sleek, easy to set up, and gives you peace of mind knowing your front porch is under watch 24/7. But soon, your neighbor asks, “Why stop at one?” Suddenly, you’re eyeing backyard coverage, a side gate, and maybe even the garage. You start wondering: How many cameras can an Arlo base station support? Is there a hard limit, or can you keep adding more until your whole property is under surveillance?

You’re not alone. Whether you’re a homeowner building a DIY security network or a small business owner scaling up, knowing the camera capacity of your Arlo base station is crucial. It affects everything from signal strength to data management. And while Arlo markets its systems as flexible and scalable, the real-world answer isn’t always straightforward. In this guide, I’ll walk you through the exact limits, explain what affects performance, and share real-life setups that work—so you can make smart decisions without hitting a wall (or a buffering camera feed).

Understanding the Arlo Base Station: The Hub of Your Security Network

Before we dive into numbers, let’s clarify what the Arlo base station actually does. Think of it as the “brain” of your wireless camera system. It’s not just a power adapter or a Wi-Fi extender—it’s a central hub that connects your Arlo cameras to your home network, manages data transmission, and stores recordings (if you’re using local storage).

What Does the Base Station Do?

• Connects cameras wirelessly using a secure 2.4 GHz or 5 GHz band (depending on the model).
• Relays video data to the cloud or to a microSD card (for local storage models).
• Manages firmware updates and device pairing.
• Enables advanced features like AI detection, motion zones, and two-way talk.

Without a base station, most Arlo Pro and Arlo Ultra cameras can’t function. The base station acts as a bridge between your cameras and your router, ensuring stable communication even when Wi-Fi signals are weak.

Types of Arlo Base Stations

Not all base stations are created equal. Arlo has released several models over the years, and each has different capabilities:

• Arlo Pro 2/3/4 Base Station (Model: VMB4000) – Supports up to 5 cameras.
• Arlo SmartHub (Model: VMB5000) – Supports up to 15 cameras (used with Arlo Pro 3, Pro 4, Ultra, Essential, and newer models).
• Arlo Pro 3/4/Ultra Base Station (Model: VMB4540) – Supports up to 5 cameras.
• Arlo Ultra 2 Base Station (Model: VMB5000R2) – Supports up to 15 cameras (same as VMB5000, but with improved firmware).
• Arlo SmartHub with Local Storage (VMB4540 + microSD slot) – Supports up to 5 cameras with optional local backup.

So, the answer to “how many cameras can an Arlo base station support?” starts with: It depends on the model. But it’s not just about the number—it’s about how those cameras perform under load.

Official Camera Limits by Arlo Base Station Model

Let’s cut to the chase. Arlo publishes official camera limits for each base station, but these numbers aren’t just arbitrary. They’re based on bandwidth, processing power, and network stability. Here’s a breakdown of what each model officially supports:

Base Station Camera Capacity (Official Numbers)

Base Station Model	Max Cameras Supported	Best For	Local Storage
VMB4000 (Pro 2/3/4)	5	Small homes, apartments	No (cloud only)
VMB4540 (Pro 3/4/Ultra)	5	Small to medium homes	Yes (with microSD)
VMB5000 (SmartHub)	15	Large homes, small businesses	Yes (with microSD)
VMB5000R2 (Ultra 2)	15	High-resolution setups, AI-heavy use	Yes (with microSD)

As you can see, the VMB5000 SmartHub is the real powerhouse, supporting up to 15 cameras. That’s ideal if you’re covering a large property with multiple entry points, driveways, and outdoor areas. The older VMB4000 and VMB4540 models, while reliable, are limited to 5 cameras—great for a typical single-family home but restrictive if you want to scale.

Real-World Example: A Family with 7 Cameras

Take Sarah, a homeowner in Texas. She started with 3 Arlo Pro 4 cameras (front, back, garage). After a package theft, she added two more (side gate and backyard). Then, she installed two Arlo Essential indoor cams for the kids’ rooms. That’s 7 cameras total.

• She used a VMB4540 base station (5-camera limit).
• After the 5th camera, the 6th and 7th wouldn’t pair.
• She upgraded to a VMB5000 SmartHub—problem solved.

Her tip? “Always plan for future expansion. I wish I’d bought the SmartHub from the start.”

Beyond the Numbers: What Affects Camera Performance?

Here’s the truth: Just because your base station supports 15 cameras doesn’t mean you should run 15 at full performance. The number is a ceiling, not a guarantee of smooth operation. Several factors can degrade performance, even within the official limit.

Bandwidth and Network Load

Each Arlo camera streams video to the base station, which then sends it to the cloud (or stores it locally). The more cameras you add, the more bandwidth you consume.

• A single Arlo Pro 4 uses about 2–3 Mbps when streaming.
• 15 cameras = 30–45 Mbps of constant upload bandwidth.

Most home internet plans offer 10–25 Mbps upload speed. If you’re already using video calls, gaming, or smart home devices, you might experience lag, buffering, or dropped connections.

Tip: Run a speed test (upload speed) before scaling. Aim for at least 1.5x your total camera bandwidth needs. For 15 cameras, 60 Mbps upload is ideal.

Wi-Fi Signal and Camera Placement

Arlo cameras connect to the base station, not directly to your Wi-Fi router. But the base station still relies on a strong Wi-Fi signal to send data to the cloud.

• Cameras too far from the base station may lose connection.
• Walls, metal objects, and interference (microwaves, baby monitors) weaken signals.
• Outdoor cameras in sheds or detached garages often need range extenders.

Tip: Place the base station centrally. Use the Arlo app’s signal strength indicator to check each camera. If a camera shows “Poor” signal, move the base station or add an Arlo Chime or SmartHub as a repeater.

Camera Resolution and Frame Rate

Higher-resolution cameras (like Arlo Ultra 2, 4K) demand more bandwidth and processing power than 1080p models (like Arlo Pro 3).

• 15 x 4K cameras = heavy load on base station and internet.
• 15 x 1080p cameras = more manageable.

Tip: Use higher resolution only where needed (e.g., front door, license plates). Use 1080p for general coverage. Adjust frame rate to 15 FPS (instead of 30) to save bandwidth.

Motion Detection and AI Features

Features like “Person Detection” and “Vehicle Detection” require more processing. The base station handles this, but too many active AI alerts can slow down the system.

Tip: Use motion zones to limit detection to key areas (e.g., only the front porch, not the entire yard). Disable AI features on less critical cameras (e.g., backyard cam).

Can You Use Multiple Base Stations? Scaling Beyond the Limit

What if you need more than 15 cameras? Say you’re running a small office, a farm, or a multi-family home. Can you add a second base station?

Yes, But With Caveats

Arlo allows you to use multiple base stations under one account. Each base station acts as a separate network, but you manage them all in the same Arlo app.

• You can have a VMB5000 in the house and another in the barn.
• Each supports up to 15 cameras.
• They appear as separate “hubs” in the app.

This is a great workaround for large properties. But there are trade-offs:

• No cross-hub alerts: A motion event on Hub 1 won’t trigger lights on Hub 2 (unless you use third-party automation like IFTTT).
• Separate storage: Local recordings are tied to each base station’s microSD card.
• More management: You’ll need to check two hubs for firmware updates and battery levels.

Practical Example: A Small Business Setup

James runs a boutique in a two-story building. He uses:

• 8 Arlo Pro 4 cameras on the ground floor (connected to VMB5000 #1).
• 7 Arlo Essential cams on the second floor (connected to VMB5000 #2).

Each hub is placed on its respective floor. He uses motion zones to reduce false alerts and schedules recordings during business hours only. “It’s not perfect,” he says, “but it’s the best way to cover a large space without overloading one hub.”

Pro Tip: Use a Network Switch

If you’re using multiple base stations, connect them to a managed network switch with QoS (Quality of Service) settings. This prioritizes Arlo traffic, reducing lag and dropouts. It’s a small investment (under $50) that pays off in reliability.

Common Mistakes and How to Avoid Them

Even with the right hardware, users often hit snags. Here are the most common issues—and how to fix them.

1. Overloading the Base Station

You bought the VMB5000, added 15 cameras, and now some are “offline” or “buffering.”

• Why it happens: Too much data, weak Wi-Fi, or poor camera placement.
• Fix: Reduce resolution/frame rate, move base station, or add a Wi-Fi extender.

2. Ignoring Upload Speed

You have 15 Mbps upload speed and 12 cameras—everything works fine… until you start a Zoom call.

• Why it happens: Bandwidth competition.
• Fix: Upgrade your internet plan or use local storage (microSD) to reduce cloud uploads.

3. Using Old Base Stations with New Cameras

You have a VMB4000 (5-camera limit) but want to use Arlo Ultra 2 cameras.

• Why it fails: The old base station can’t handle the higher bandwidth and AI features.
• Fix: Upgrade to VMB5000 or VMB5000R2. Check compatibility on Arlo’s website.

4. Not Testing Signal Strength

You place a camera in the backyard, but it disconnects every few hours.

• Why it happens: Weak signal from base station.
• Fix: Use the Arlo app to check signal strength. Add a SmartHub or Chime as a repeater.

5. Forgetting About Firmware Updates

Your cameras stop working after a power outage.

• Why it happens: Outdated firmware causes compatibility issues.
• Fix: Enable auto-updates in the Arlo app. Check for updates monthly.

Final Thoughts: Choosing the Right Base Station for Your Needs

So, how many cameras can an Arlo base station support? The short answer: 5 to 15, depending on the model. But the real answer is more nuanced. It’s not just about hitting the max number—it’s about maintaining performance, reliability, and ease of use.

If you’re covering a small home, the VMB4540 (5-camera limit) is sufficient. But if you’re planning for growth, the VMB5000 SmartHub (15 cameras) is worth the extra cost. It gives you room to expand, better bandwidth handling, and local storage options.

And remember: You can use multiple base stations. This is the best way to scale beyond 15 cameras without sacrificing quality. Just make sure your internet, Wi-Fi, and placement are optimized.

Here’s my final advice: Think like a planner, not a shopper. Don’t just buy what you need today. Consider what you might need in 1–2 years. A few extra dollars now can save you from a frustrating upgrade later.

Whether you’re protecting your home, business, or loved ones, Arlo’s flexibility is a strength—but only if you use it wisely. With the right base station and setup, you can build a security network that’s as smart as it is scalable.

Now, go check your upload speed, map out your camera zones, and pick the base station that fits your future. Your peace of mind is worth it.
