But then, the thought hits you—can I just leave this thing plugged in all the time? No more swapping batteries every few weeks? No more worrying about dead cameras during a storm or a break-in? That sounds like a dream, right?

If you’ve ever found yourself staring at your Arlo Pro, wondering whether it’s okay to keep it powered 24/7, you’re not alone. A lot of people ask this question, especially those who’ve grown tired of the constant battery changes. The good news? It’s definitely possible. But—and there’s always a “but”—there are a few things you should know before you go all-in on permanent power. From battery health to performance, power supply quirks, and even weatherproofing, there’s more to this than just plugging it in and forgetting it.

So, let’s break it down. In this post, we’ll explore whether keeping your Arlo Pro camera permanently plugged in is safe, smart, and sustainable. We’ll look at the pros, the cons, the technical details, and even share some real-life tips from users who’ve done it. Whether you’re a new Arlo owner or a long-time user looking to streamline your setup, this guide is for you. And hey, if you’ve already been running your camera plugged in for months (or years), we’ll help you figure out if you’re doing it right—or if it’s time for a change.

How the Arlo Pro Camera Is Designed: Battery vs. Wired Power

The Original Intent: Battery-Powered Freedom

The Arlo Pro line—including the Arlo Pro, Pro 2, Pro 3, and Pro 4—was originally designed with battery-powered operation as its core feature. This means the cameras come with rechargeable batteries that last anywhere from 3 to 6 months, depending on usage, motion sensitivity, and environmental factors. The idea was to offer a truly wireless experience: no drilling, no wires, no power outlets needed. You could install the camera anywhere—on a tree, under an eave, even on a fence—and it would just work.

But here’s the catch: that convenience comes with trade-offs. Batteries degrade over time. Cold weather drains them faster. And if you forget to swap them, you’re left with a blind spot. That’s where the option to plug in comes in.

The Hidden Power Option: AC Adapter Support

Even though Arlo Pro cameras are marketed as battery-powered, they do support continuous power via an AC adapter. Arlo sells a weather-resistant power adapter (sold separately for most models) that connects directly to the camera. This adapter plugs into a standard wall outlet and provides a steady 5V DC power supply. It’s not just a charging dock—it’s a full-time power source.

For example, the Arlo Pro 3 and Pro 4 come with a built-in magnetic charging port on the back. You can attach the adapter cable, plug it in, and the camera will run indefinitely—no battery swaps required. The Pro and Pro 2 require a slightly different setup (using a charging cradle), but the concept is the same: continuous power is possible.

What Arlo Says About Permanent Power

Arlo doesn’t discourage permanent power use. In fact, their official support pages confirm that you can keep the camera plugged in 24/7. They even recommend it for high-traffic areas or critical monitoring spots where you can’t afford downtime. However, they do include a few caveats—like making sure the power adapter is weatherproof and installed correctly.

So yes, the design allows it. But that doesn’t mean it’s risk-free. Let’s talk about what happens when you keep the battery in the camera while it’s constantly powered.

What Happens to the Battery When You Keep the Arlo Pro Plugged In?

Charging Cycles and Battery Health

Here’s a common misconception: if you leave your Arlo Pro plugged in, the battery will overcharge and explode. Spoiler: that’s not how it works. Modern lithium-ion batteries (like the one in your Arlo) have built-in protection circuits that prevent overcharging. Once the battery reaches 100%, the system switches to trickle charging or simply stops drawing power from the battery—using the wall outlet instead.

But there’s a catch: heat. When a lithium-ion battery is kept at 100% charge for long periods—especially in warm environments—it can degrade faster. Think of it like a phone that’s always plugged in overnight. Over time, the battery’s maximum capacity drops. For Arlo Pro users, this means:

• The battery may hold less charge over time (e.g., from 6 months to 4 months).
• Eventually, you might need to replace the battery even if you’re not using it much.
• In extreme cases, the battery can swell or fail prematurely.

Real-World Battery Longevity: User Experiences

We’ve heard from users who’ve kept their Arlo Pro 3 plugged in for over two years. Some report no issues—their battery still holds a charge when unplugged. Others noticed a 20–30% reduction in battery life after 18 months. One user in Arizona (where temps regularly hit 100°F+) said his battery swelled after 14 months of continuous power.

So, the takeaway? It depends on your environment and usage. Cooler climates, proper ventilation, and lower ambient temperatures help. But if you live in a hot garage or under direct sun, heat buildup can accelerate battery wear.

Pro Tip: Remove the Battery (But Only If You Want To)

If you’re committed to permanent power, consider removing the battery entirely. Arlo designed the Pro 3 and Pro 4 to run without a battery when connected to continuous power. This eliminates the risk of overcharging and heat damage. Just plug in the adapter, and the camera draws power directly from the wall.

But—and this is important—if you remove the battery, you lose backup power. If the electricity goes out, your camera shuts down. For many, that’s a dealbreaker. For others (like those with generators or uninterruptible power supplies), it’s a smart move to extend battery lifespan.

Power Supply and Installation: What You Need to Know

Choosing the Right Power Adapter

Not all power adapters are created equal. Arlo’s official adapter is rated for outdoor use (IP65 weather resistance) and delivers a stable 5V/2A output. Third-party adapters might work, but they come with risks:

• Voltage fluctuations can damage the camera.
• Cheap cables can overheat or short-circuit.
• Non-weatherproof adapters can fail in rain or snow.

Stick with Arlo’s branded adapter or a certified third-party alternative (look for IP65 or IP67 ratings and 5V/2A output). Don’t use a phone charger—it’s not designed for continuous outdoor use.

Running Power Safely: Wiring and Weatherproofing

Running a power cable from your wall outlet to your camera? You’ll need to think about:

• Cable length: The Arlo adapter cable is 10 feet long. If your camera is farther, use a weatherproof extension cord (rated for outdoor use).
• Cable management: Use conduit, cable clips, or raceways to protect the wire from UV damage, pests, and physical wear.
• Weatherproof connections: Use silicone sealant or waterproof tape on joints. Consider a weatherproof junction box if you’re splicing wires.
• Grounding: If you’re running a long extension, ensure it’s grounded to prevent surges.

One user shared a great tip: run the cable through PVC conduit painted to match your house. It looks clean, protects the wire, and lasts years.

Power Outages and Backup Options

Remember: if you remove the battery, your camera dies when the power goes out. Solutions?

• Use a battery backup (UPS) for the outlet. Even a small UPS can keep your camera running for 2–4 hours.
• Keep a spare battery on hand and reinsert it during outages (if you removed it).
• Use a generator or solar-powered outlet for critical areas.

For example, one homeowner in Florida uses a solar-powered outlet for his Arlo Pro at the back gate. No grid power needed—and it works during hurricanes.

Performance and Features: Does Plugged-In Power Change Anything?

Video Quality and Streaming

Good news: plugged-in power doesn’t affect video quality. Whether you’re using battery or AC, the camera records in the same resolution (e.g., 2K for Pro 3, 1080p for Pro 2). Frame rates, HDR, and night vision all work the same.

But here’s a subtle difference: when the camera is plugged in, it can record continuously (if you have an Arlo Smart subscription). Battery-powered cameras typically use event-based recording (only when motion is detected) to save power. With constant power, you can enable 24/7 recording—great for high-traffic areas like driveways or front doors.

Motion Detection and Alerts

Motion detection works the same, but plugged-in cameras can process more data without worrying about battery drain. This means:

• Faster response times to motion events.
• More reliable AI detection (e.g., person, package, vehicle).
• Less chance of missed alerts due to low battery.

One user noticed that his Arlo Pro 3 (plugged in) detected a package delivery 3 seconds faster than his battery-only camera. Not a huge difference, but noticeable when you’re waiting for a delivery.

Audio and Two-Way Talk

The built-in speaker and microphone perform the same. However, continuous power means the camera stays in a “ready” state, so two-way talk is more responsive. No lag when you press the talk button.

Bonus: some users report better audio quality when plugged in, possibly because the camera isn’t conserving power during audio transmission.

Pros and Cons of Keeping Your Arlo Pro Permanently Plugged In

The Pros: Why You Should Consider It

• No battery swaps: Set it and forget it. No more climbing ladders every few months.
• Continuous recording: With a subscription, you get full 24/7 video history.

Final Thoughts: Is Permanent Power Right for Your Arlo Pro?

So, can you keep the Arlo Pro camera permanently plugged in? Absolutely—and many people do it successfully. It’s a great option if you want reliability, continuous recording, and less maintenance. But it’s not a one-size-fits-all solution.

If you’re installing your camera in a high-traffic area—like a front porch, garage, or backyard—permanent power is a smart move. You’ll get better performance, fewer headaches, and peace of mind knowing your camera won’t die when you need it most. Just make sure to:

• Use the official Arlo adapter or a high-quality alternative.
• Weatherproof all connections.
• Consider removing the battery (if you have backup power).
• Monitor battery health if you keep it in.

On the other hand, if you’re renting, have limited access to power outlets, or live in an area with frequent outages, sticking with battery power might be better. Or, you could use a hybrid approach: plug in the most critical cameras, and keep the rest on battery.

At the end of the day, it’s about your needs, your setup, and your peace of mind. The Arlo Pro is flexible enough to handle both options. And now that you know the ins and outs of permanent power, you can make an informed choice—no more guessing, no more worrying about dead batteries.

So go ahead. Plug it in. Set it up right. And enjoy the freedom of a camera that’s always ready to watch over your home. After all, security shouldn’t be a chore. It should just work.
