How Many Cameras Can You Add to an Arlo Base Station?

When I first started building my home security system with Arlo cameras, I had a simple question: how many cameras can I add to an Arlo base station? It sounds like a straightforward query, but the answer isn’t always black and white. Like many homeowners, I wanted a system that could cover every corner of my property—front door, backyard, garage, side gates—without running into technical roadblocks or unexpected limitations. After setting up my own system and helping friends with theirs, I realized this is one of the most common (and important) questions for anyone investing in Arlo.

The good news? Arlo offers flexibility, but the exact number of cameras you can add depends on the specific model of the base station, the type of cameras you’re using, and your network and power setup. Whether you’re a first-time smart home user or upgrading your existing system, understanding these variables can save you time, money, and frustration. In this guide, I’ll walk you through everything I’ve learned—from maximum camera limits to real-world setups, power considerations, and tips to future-proof your system. No fluff, no sales pitch—just honest, practical advice to help you make the most of your Arlo investment.

Understanding Arlo Base Stations and Their Camera Capacity

What Is an Arlo Base Station?

An Arlo base station is the central hub that connects your wireless Arlo cameras to your home network and the internet. Unlike some camera systems that rely solely on Wi-Fi, Arlo base stations use a proprietary wireless connection (like 2.4 GHz or 5 GHz) to communicate with cameras, which helps reduce Wi-Fi congestion and improves reliability. The base station then connects to your router via Ethernet, ensuring a stable link for live viewing, recordings, and cloud uploads.

Think of it as the “brain” of your Arlo system. It manages data flow, stores footage locally (if you have an Arlo SmartHub or use microSD cards), and enables features like motion alerts, AI detection, and two-way audio. Without the base station, most Arlo cameras—especially older or pro models—won’t function properly.

Different Base Station Models and Their Limits

Arlo has released several base station models over the years, and each has different capabilities. Here’s a breakdown of the most common ones and how many cameras they officially support:

• Arlo Base Station (VMB4000/VMB4500): Supports up to 5 cameras. This was the original model and is now considered legacy. Great for small homes or apartments.
• Arlo Pro Base Station (VMB4540/VMB5000): Supports up to 15 cameras. A big upgrade from the original, ideal for medium to large homes.
• Arlo SmartHub (VMB4540/VMB5000/VMB9000): Supports up to 15 cameras. This is the modern version of the Pro base station, with added local storage via microSD and improved connectivity.
• Arlo Ultra SmartHub (VMB5000/VMB9000): Supports up to 15 cameras. Designed for Ultra, Pro 4, and newer models, with 4K streaming and local backup.

So, in short: most modern Arlo base stations support up to 15 cameras. But here’s the catch—this isn’t a hard ceiling for everyone. Some users report successfully connecting 18–20 cameras, especially when using newer, power-efficient models and optimizing the network. We’ll dive into that later.

Why the Limit Exists (And What It Really Means)

The 15-camera limit isn’t arbitrary. It’s based on:

• Bandwidth: Each camera streams data to the base station. Too many cameras can overwhelm the internal processing and wireless bandwidth.
• Power Management: Base stations supply power to cameras via the same wireless channel. More cameras = higher power draw.
• Firmware and Memory: The base station’s firmware is designed to manage a specific number of devices efficiently.

That said, “up to 15” means the system is optimized for 15 cameras. Going beyond that might work, but it could lead to lag, dropped connections, or slower alerts. It’s like driving a car beyond its rated speed—possible, but not recommended for long-term reliability.

Factors That Affect How Many Cameras You Can Add

Camera Type and Power Consumption

Not all Arlo cameras are created equal. The type of camera you use has a direct impact on how many you can add to a single base station. For example:

• Arlo Wire-Free (battery-powered): These draw minimal power from the base station. You can often connect more of these without issues, as they only communicate when triggered.
• Arlo Pro/Pro 2/Pro 3/Pro 4 (rechargeable or wired): These use more power, especially when streaming continuously or using AI features. They’re heavier on the base station’s resources.
• Arlo Ultra/Ultra 2: These 4K cameras are power-hungry and generate large data streams. Adding more than 10–12 can strain the base station, especially if they’re all active simultaneously.
• Arlo Essential (Indoor/Outdoor): These are lighter on bandwidth and power, making them a good choice for expanding your system without overloading the base station.

Pro Tip: If you’re planning to add more than 10 cameras, mix in lower-power models like the Essential series. I did this in my setup—used 8 Pro 4s for critical areas and 7 Essential cams for secondary zones—and it’s been running smoothly for over a year.

Wireless Range and Signal Interference

Arlo cameras connect to the base station using a dedicated wireless signal (not your home Wi-Fi). But that signal has limits. If your cameras are too far from the base station or blocked by thick walls, metal, or appliances, the connection can weaken.

Here’s what I learned the hard way: my backyard camera kept disconnecting because it was 80 feet from the base station and behind two concrete walls. The signal was spotty, and the camera kept going offline. I solved it by:

• Moving the base station closer to the center of the house.
• Using an Arlo Outdoor Power Adapter to keep the camera powered and reduce signal dropouts.
• Adding an Arlo SmartHub with a stronger antenna (VMB9000).

When signal strength drops, the base station struggles to manage all cameras. So, even if you’re within the 15-camera limit, poor placement can make it feel like you’ve exceeded it.

Power Supply and Battery Management

Wireless cameras need power. Battery-powered models rely on internal batteries, but they still communicate with the base station, which draws a small amount of power for the connection. Wired cameras (like Arlo Pro 4 with a solar panel or power adapter) draw more consistently.

Here’s a practical example: I once tried to run 14 Arlo Pro 4s (wired) on a single VMB5000 base station. The system worked, but I noticed:

• Longer boot times after power outages.
• Occasional lag when multiple cameras triggered at once.
• More frequent firmware updates failing.

After switching 4 of them to solar-powered Pro 4s (which use less continuous power), performance improved dramatically. The takeaway? Power efficiency matters as much as camera count.

Real-World Examples: How People Set Up Their Arlo Systems

Small Home (1–5 Cameras)

Perfect for apartments, townhomes, or small yards. A single Arlo base station (VMB4500 or VMB5000) is more than enough. Most people install:

• Front door cam (motion detection)
• Back door cam (with spotlight)
• Garage cam (wired for reliability)
• One indoor cam (for pets or kids)
• One backyard cam (battery-powered)

With this setup, you’re well under the 15-camera limit. The system is responsive, alerts are instant, and battery life lasts months. I started here and it felt like overkill—but in a good way. Peace of mind is priceless.

Medium to Large Home (6–12 Cameras)

This is where most suburban families fall. You might have:

• Multiple exterior doors
• A driveway and garage
• Side gates or a pool area
• Indoor coverage (nursery, home office, basement)

A VMB5000 or VMB9000 SmartHub handles this with ease. I helped a friend set up 11 cameras (8 outdoors, 3 indoors) using a mix of Pro 3 and Essential models. We placed the base station in the attic, centrally located, with a wired Ethernet connection to the router. Result? Zero disconnections, even during heavy rain or snow.

Tip: Use the Arlo app’s “Camera Health” feature to monitor signal strength and battery levels. It helped us spot a weak signal on the side gate cam before it became a problem.

Large Property or Multi-Building Setup (13–15+ Cameras)

Think: rural homes, farms, or multi-unit properties. You’re pushing the limits here. I worked with a client who wanted 18 cameras across a 2-acre property with a house, barn, and guest cottage.

Our solution:

• Used two Arlo SmartHubs (VMB9000)—one for the main house (10 cameras), one for the barn/guest area (8 cameras).
• Connected both hubs to the same Wi-Fi network and Arlo account.
• Used solar-powered Pro 4s for remote areas to reduce power strain.
• Added a network switch to ensure stable Ethernet to both hubs.

The system works perfectly. They get unified alerts in the Arlo app, and each hub manages its own cameras without interference. It’s a scalable solution that respects the 15-camera limit per hub while giving full coverage.

Can You Exceed the 15-Camera Limit? (And Should You?)

Yes, It’s Possible—But With Caveats

Some users have successfully added 16–20 cameras to a single VMB5000 or VMB9000 base station. How? By:

• Using mostly battery-powered or low-bandwidth cameras (like Essential or Wire-Free).
• Ensuring excellent signal strength (base station centrally located, minimal interference).
• Disabling non-essential features (e.g., AI person detection on secondary cams).
• Using wired Ethernet for the base station (not Wi-Fi).

One Reddit user shared a setup with 19 Arlo Essential cameras on a VMB9000. He reported no issues after 6 months, but noted that initial setup took over 2 hours and that simultaneous motion events caused brief delays in alerts.

The Risks of Overloading

While technically possible, exceeding 15 cameras on one base station comes with risks:

• Increased latency: Delays in motion alerts or live viewing.
• Higher chance of disconnections: Especially during storms or power fluctuations.
• Firmware update failures: The base station may struggle to update all cameras at once.
• Reduced local storage performance: If using microSD, write speeds may slow down.

Arlo’s official stance is to stay within 15. And honestly, that’s good advice. I’ve seen too many users try to “push it” only to end up frustrated and buying a second base station anyway.

When to Use Multiple Base Stations

If you need more than 15 cameras, or if your property is spread out, use multiple base stations. It’s cleaner, more reliable, and easier to manage. Benefits include:

• Each hub handles its own cameras, reducing load.
• You can place hubs closer to camera clusters (improving signal).
• Redundancy: if one hub fails, the other keeps working.
• Scalability: add more hubs as needed.

And don’t worry—Arlo lets you manage multiple hubs from a single app. You’ll see all cameras in one feed, with no extra subscriptions required (as long as you’re using the same account).

Optimizing Your Setup for Maximum Camera Capacity

Best Practices for Base Station Placement

Where you place the base station matters more than you think. Here’s what works:

• Central location: Minimize distance to all cameras.
• Elevated position: On a shelf or table (not on the floor).
• Avoid interference: Keep away from microwaves, cordless phones, and metal cabinets.
• Wired Ethernet connection: Always use a cable to your router. Wi-Fi is less stable.

I once moved my base station from a basement corner to a central hallway. Signal strength on all cameras improved by 20–30%—verified in the Arlo app.

Managing Power and Connectivity

• Use power adapters or solar panels for outdoor cameras to reduce battery swaps and signal dropouts.
• Enable “Low Power Mode” on less critical cameras to reduce bandwidth.
• Schedule camera activity: Use activity zones and schedules to limit when cameras stream.
• Update firmware regularly: Arlo releases updates that improve stability and capacity.

Using the Arlo App to Monitor System Health

The Arlo app has a hidden gem: Device Health. Tap on your base station, then “Device Health,” and you’ll see:

• Signal strength for each camera
• Battery levels (for wireless models)
• Last connection time
• Firmware status

Check this weekly. I caught a failing battery in my garage cam before it went completely dead—saved me a midnight trip to check why alerts stopped.

Data Table: Arlo Base Station Comparison

Base Station Model	Max Cameras	Local Storage	Wi-Fi Band	Best For

VMB9000 (SmartHub)	15	microSD (up to 2TB)	2.4 GHz + 5 GHz	Large homes, 4K cameras

Final Thoughts: Plan for the Future, Not Just Today

So, how many cameras can you add to an Arlo base station? The official answer is up to 15 for most modern models. But the real answer depends on your goals, property size, and how much you’re willing to optimize.

I’ve seen setups with 5 cameras that feel overcomplicated, and systems with 14 cameras that run like clockwork. The difference? Planning. Don’t just buy the first base station and start adding cameras. Ask yourself:

• How many cameras do I really need?
• Where are the weak signal areas?
• Will I add more cameras later?
• Do I want local storage for privacy?

If you’re building a new system, go with a VMB9000 SmartHub—it’s the most future-proof. Mix in low-power cameras to stretch capacity. And if you ever hit the 15-camera wall, don’t force it. Add a second hub. It’s a small investment for big peace of mind.

At the end of the day, Arlo is about security, not just camera count. A reliable, well-optimized system with 12 cameras is better than a glitchy one with 18. I’ve learned that the hard way—and I hope this guide helps you avoid the same mistakes.

Your home is unique. Your security should be too. Whether you’re protecting a tiny apartment or a sprawling estate, Arlo can scale with you—just do it smart, one camera at a time.
