The Arlo Dilemma: Do These Cameras Slow Down Your WiFi?

Imagine this: You’re finally relaxing after a long day, streaming your favorite show, and—bam!—the screen freezes. You check your phone, and the WiFi icon shows full bars. But your smart home devices seem sluggish. Sound familiar? If you’ve got Arlo cameras, you might be wondering if they’re the culprit behind your lagging connection.

Arlo cameras are popular for good reason—they’re sleek, wireless, and offer excellent home security. But with more devices on your network, it’s natural to ask: do Arlo cameras slow down WiFi? I’ve been there. After installing four Arlo Pro 3 cameras in my house, I noticed my video calls stuttering and downloads crawling. So, I dug deep into the tech, tested different setups, and even chatted with network experts. Here’s what I found—no fluff, just real answers to help you decide if Arlo fits your home without turning your internet into a snail’s race.

How Arlo Cameras Use Your WiFi (And Why It Matters)

The Basics: Arlo’s Wireless Design

Arlo cameras are designed to be wireless, which is great for installation flexibility. But that also means they rely heavily on your home WiFi network. Unlike traditional wired security systems, Arlo cameras transmit data—live video, motion alerts, and recordings—over WiFi to the cloud. This is convenient, but it also means your network has to handle extra traffic.

For example, if you have two Arlo Pro 3 cameras recording 1080p video at 15 frames per second, each camera might use about 1.5 to 2 Mbps of bandwidth. That’s not massive on its own, but it adds up—especially if you’re streaming Netflix, gaming, or working from home simultaneously. Think of it like cars on a highway: one or two Arlo cameras are like sedans—they cruise along fine. But add a few more (plus your smart TV, laptop, and phone), and suddenly you’re in rush-hour traffic.

WiFi Frequency Bands: 2.4 GHz vs. 5 GHz

Arlo cameras typically connect to your router using the 2.4 GHz band. This band has a longer range and better wall penetration, which is why it’s ideal for devices spread across a house. However, it’s also more crowded and prone to interference from microwaves, baby monitors, and other devices. The 5 GHz band, while faster, has a shorter range and struggles with walls.

Here’s a practical tip: If your router supports dual-band (most do), make sure your non-Arlo devices—like your laptop or phone—connect to the 5 GHz band for faster speeds. Keep Arlo cameras on the 2.4 GHz band. This way, your high-bandwidth activities (like streaming) aren’t competing with your cameras for the same airspace.

For instance, in my setup, I moved my work laptop to 5 GHz and left the Arlo base station on 2.4 GHz. The result? My Zoom calls stopped dropping, and my camera alerts stayed prompt. It’s a simple tweak, but it made a big difference.

When Arlo Cameras Might Actually Slow Down Your WiFi

Too Many Cameras on One Network

Let’s say you have six Arlo cameras running 24/7. Even if each uses only 2 Mbps, that’s 12 Mbps total—just for cameras. Add in your TV (5 Mbps for HD streaming), a gaming console (10 Mbps), and a few phones, and you’re looking at 30+ Mbps of constant demand. If your internet plan is 50 Mbps or less, you’ll start feeling the strain.

I learned this the hard way. When I added a fifth Arlo camera, my internet felt sluggish during peak hours. My ISP’s speed test showed I was getting 45 Mbps, but real-world performance (like loading websites or streaming) felt like 20 Mbps. Why? Because my router was struggling to manage all the devices efficiently.

Low-Quality or Outdated Routers

Not all routers are built equal. Older models (think pre-2018) often lack the processing power or advanced traffic management (QoS) to handle multiple smart devices. If your router is more than three years old, it might not prioritize traffic well, causing Arlo cameras to hog bandwidth.

For example, my old Netgear router couldn’t distinguish between a camera upload and a video call. So, when my cameras uploaded footage, my Zoom call would freeze. Upgrading to a modern router with QoS (Quality of Service) settings fixed this. I set my camera traffic to “low priority” and my work calls to “high priority.” Problem solved.

Interference and Network Congestion

WiFi interference isn’t just about other devices—it’s also about physical obstacles. Thick walls, metal objects, and even large appliances can weaken signals. If your Arlo cameras are far from the router or in a “dead zone,” they’ll struggle to maintain a stable connection. To compensate, they might retransmit data, creating a feedback loop of slow speeds.

One user in a Facebook smart home group shared a relatable story: Their Arlo cameras worked fine until they added a new microwave oven. Every time they used it, the cameras dropped offline. The fix? Moving the router closer to the kitchen and using a WiFi extender for the cameras.

How to Prevent Arlo from Slowing Down Your WiFi

Upgrade Your Router (If Needed)

If your router is old or basic, consider upgrading to a modern mesh system. These systems use multiple nodes to blanket your home in WiFi, reducing dead zones and improving stability. Brands like Eero, Google Nest WiFi, and TP-Link Deco are excellent choices.

For example, after switching to an Eero Pro 6 mesh system, my Arlo cameras connected seamlessly across three floors. The system automatically balanced traffic, so my cameras didn’t interfere with my work or entertainment devices. It cost a bit upfront ($200–$300), but the peace of mind was worth it.

Use a Dedicated Network for Arlo Cameras

Most modern routers let you create a separate network (often called a “guest network” or “IoT network”) for smart devices. This isolates your Arlo cameras from your primary devices, reducing congestion.

Here’s how to set it up:

• Log into your router’s admin panel (usually via 192.168.1.1 or 192.168.0.1).
• Look for “Network Settings” or “Guest Network.”
• Create a new network (e.g., “HomeCameras”) on the 2.4 GHz band.
• Connect all Arlo devices to this network.

This way, your cameras won’t compete with your laptop or TV for bandwidth. I did this with my Arlo setup, and the difference was night and day. No more buffering during video calls!

Adjust Arlo Camera Settings for Efficiency

You don’t need your cameras recording in 4K 24/7. Lowering the resolution, frame rate, or motion detection sensitivity can significantly reduce bandwidth usage.

For example:

• Resolution: Drop from 4K to 1080p—saves ~1 Mbps per camera.
• Frame rate: Reduce from 30 fps to 15 fps—cuts bandwidth by half.
• Motion zones: Set narrow zones to avoid false alerts (and unnecessary uploads).

I tested this with my front-yard camera. By switching to 1080p at 15 fps, its bandwidth dropped from 2.5 Mbps to 1.2 Mbps. That’s a 52% reduction—and the video quality is still crisp for security purposes.

Real-World Data: Arlo Bandwidth Usage Compared

To give you a clear picture, here’s a breakdown of average bandwidth usage for different Arlo models. These numbers are based on Arlo’s official specs and real-world tests from users (including my own setup):

Arlo Model	Resolution	Bandwidth (Mbps)	Best For
Arlo Essential	1080p	1.0–1.5	Small homes, budget setups
Arlo Pro 3	2K	1.5–2.5	Medium to large homes
Arlo Ultra	4K	2.5–4.0	High-security needs (e.g., large properties)
Arlo Wire-Free (older models)	720p	0.8–1.2	Basic monitoring

Note: Bandwidth varies based on motion activity, WiFi quality, and cloud upload settings.

For context, here’s how Arlo compares to other smart devices:

• Streaming (Netflix HD): 5 Mbps
• Video call (Zoom): 3–5 Mbps
• Gaming (online): 10–15 Mbps

So, if you have three Arlo Pro 3 cameras (7.5 Mbps total), they’ll use less bandwidth than one HD stream but more than a Zoom call. This means they’re not inherently “slow,” but they can contribute to congestion in busy networks.

Myth Busting: Common Misconceptions About Arlo and WiFi

Myth #1: “Arlo Cameras Always Use WiFi”

Not true! Many Arlo models (like the Pro 3 and Ultra) use a base station that connects to your router via Ethernet. The cameras then connect to the base station using a private, low-interference radio frequency (not WiFi). This offloads traffic from your main network.

In my setup, the base station is wired to my router in the basement. The cameras connect wirelessly to the base station, not my WiFi. This means they don’t directly compete with my other devices—a huge win for network stability.

Myth #2: “More Cameras = Always Slower WiFi”

It depends on your network. A well-configured, modern router can handle 10+ smart devices without breaking a sweat. The real issue is how you set up your network—not just the number of devices.

For example, a friend with eight Arlo cameras and a 300 Mbps fiber connection has zero WiFi issues. Why? Their mesh router and QoS settings keep traffic balanced. Meanwhile, my old setup with five cameras and a 50 Mbps plan felt sluggish. The takeaway? Your router and internet plan matter more than the camera count.

Myth #3: “You Need a Gigabit Connection for Arlo”

Unless you’re running a dozen 4K cameras, a 100–200 Mbps plan is more than enough. Even with four Arlo Pro 3 cameras, my 100 Mbps connection handles everything smoothly—thanks to smart network management.

Final Thoughts: Should You Worry About Arlo Slowing Down Your WiFi?

So, do Arlo cameras slow down WiFi? The short answer: They can, but they don’t have to. Like any smart device, Arlo cameras add demand to your network—but with the right setup, they won’t ruin your internet experience.

Here’s what I’d recommend:

• Audit your current network: Run a speed test (try Speedtest.net) to see if your connection is already struggling.
• Upgrade if needed: A modern mesh router or a plan with more bandwidth can work wonders.
• Optimize your setup: Use a dedicated network, adjust camera settings, and position devices strategically.
• Start small: Add one or two cameras first, then monitor performance before scaling up.

For most homes, Arlo is a fantastic choice—especially if you value wireless convenience and reliable security. But if you’re on a tight budget or have an older router, it’s worth addressing those issues first. At the end of the day, your WiFi speed depends on your entire ecosystem, not just one device.

I still love my Arlo cameras. They’ve given me peace of mind, and with a few tweaks, they coexist perfectly with my other devices. The key is to treat your network like a team: Every device has a role, and with smart management, they can all work together—without slowing each other down.
