Are Arlo Cameras IR? The Ultimate Night Vision Guide

Let’s be honest—when you’re setting up a home security system, the last thing you want is to realize your cameras can’t see at night. You’ve invested in Arlo for its sleek design, easy setup, and smart features, but the real test comes after sunset. Are Arlo cameras IR? Do they actually work in the dark? And more importantly, will they catch that raccoon digging through your trash or, worse, an intruder sneaking around your back door?

I’ve been there. I remember setting up my first Arlo Pro 4, excited to finally have 2K video and two-way audio. Then, I checked the app at 2 a.m. and saw nothing but darkness. Panic set in. Was it broken? Was the IR not working? Turns out, it was working—just not as I expected. That experience led me down a rabbit hole of understanding how Arlo’s night vision works, what IR really means, and how to get the most out of your cameras after the sun goes down. This guide is everything I wish I knew then. Whether you’re a first-time buyer or troubleshooting your current setup, we’ll cover how Arlo’s IR technology works, which models offer it, and how to optimize it for crystal-clear nighttime footage.

What Does “IR” Mean and Why It Matters for Security Cameras

Understanding Infrared (IR) Technology

IR stands for infrared, a type of invisible light that sits just beyond the red end of the visible spectrum. Unlike regular light, infrared isn’t visible to the human eye, but it can be detected by camera sensors. This is the secret behind night vision on security cameras. When ambient light drops—like at night—IR LEDs around the camera’s lens turn on and flood the area with infrared light. The camera then captures that reflected light, creating a black-and-white image in near-total darkness.

Think of it like night vision goggles used by soldiers or wildlife researchers. The IR illuminators act like silent flashlights that only the camera can see. No bright white light, no blinding neighbors—just stealthy, effective visibility.

Why IR Is Essential for Home Security

Without IR, your camera is blind after dark. Imagine this: a motion alert pops up at 3 a.m., but the video shows only a black screen. That’s not just frustrating—it’s a security risk. IR night vision ensures you get usable footage 24/7. Whether it’s a delivery driver at your front door, a pet wandering into a restricted zone, or someone trying to break in, IR helps you see what’s happening.

For example, I once caught a neighbor’s dog repeatedly entering my yard through a loose fence panel. Without IR, I would’ve assumed it was a raccoon and wasted time setting up traps. Instead, I saw the dog clearly, fixed the fence, and avoided a costly pest control call. That’s the power of IR.

How Arlo Uses IR Differently Than Other Brands

Not all IR is created equal. Some brands use visible white light for night vision (like floodlights), which can be disruptive. Arlo, however, focuses on infrared-only night vision in most of its models. This means no blinding lights—just discreet, silent monitoring.

Arlo also uses adaptive IR in newer models. The camera automatically adjusts IR intensity based on distance and ambient light. For instance, if someone walks up to your front door, the IR dims slightly to avoid overexposure. If they step back into the shadows, it brightens. This prevents “washed-out” faces up close and ensures clarity at longer ranges.

Which Arlo Cameras Offer IR Night Vision (And Which Don’t)

Full IR Support: The “Always-On” Night Vision Models

Most Arlo cameras are designed with IR night vision as a core feature. Here’s a quick breakdown:

• Arlo Pro 5S / Pro 4 / Pro 3: All use 850nm IR LEDs with a 25-foot (7.6m) range. These are the workhorses of Arlo’s lineup, offering crisp black-and-white footage in total darkness.
• Arlo Ultra 2 / Ultra: Upgraded to 940nm IR LEDs, which are slightly less visible to the human eye (a “stealthier” glow). Range: 30 feet (9.1m). Great for larger properties.
• Arlo Essential Series (Indoor/Outdoor, Spotlight, Doorbell): All include IR. The Essential Outdoor and Spotlight models have 20-foot (6m) IR range, perfect for entryways and porches.
• Arlo Pro 5 (2nd gen): Combines 850nm IR with color night vision (via a built-in spotlight). When motion is detected, the spotlight turns on, and the camera switches to color mode.

Partial or No IR: Exceptions to the Rule

Not every Arlo product relies on IR. Be cautious with these:

• Arlo Video Doorbell (Wired): Uses low-light sensor and a small LED for illumination, but no IR. Works best in areas with ambient light (e.g., porch lights). In total darkness, footage may be grainy.
• Arlo Go 2 (LTE Camera): Has IR, but the range is limited to 15 feet (4.6m) due to power constraints. Ideal for remote areas, not large yards.
• Arlo Baby Monitor: Uses IR for night vision, but it’s optimized for a nursery (soft glow, no harsh LEDs). Not for general home security.

Pro Tip: Check the Specs Before Buying

Always verify the IR range and wavelength in the product description. For example, if you’re monitoring a 40-foot-long driveway, a camera with a 20-foot IR range won’t cut it. Pair a long-range model (like Arlo Ultra 2) with a wide-angle lens to cover more ground.

How Arlo’s IR Night Vision Works: Behind the Scenes

The Role of IR Cut Filters

Ever notice how your Arlo footage switches from color to black-and-white at night? That’s thanks to the IR cut filter. During the day, this filter blocks infrared light, so your video stays true to real-world colors. At night, the filter retracts, allowing the camera to capture IR light for night vision.

Without this filter, your daytime footage would look weirdly red or washed out. Arlo’s seamless transition between modes ensures you get accurate visuals 24/7.

IR Intensity and Range: What Affects Performance?

Several factors influence how well your Arlo’s IR works:

• IR LED Count: More LEDs = brighter illumination. Arlo Pro 4 has 8 LEDs; Arlo Ultra 2 has 12.
• Wavelength (850nm vs. 940nm):
  • 850nm: Brighter, better for long ranges, but emits a faint red glow (visible in the dark).
  • 940nm: No visible glow, but shorter range and lower intensity. Best for discreet monitoring.
• Obstructions: Rain, fog, or glass can scatter IR light, reducing clarity. For example, mounting a camera behind a window may cause glare or reduced range.
• Power Source: Battery-powered Arlo cameras (like Pro 4) may reduce IR intensity to save power. Wired models (like Ultra 2) maintain full brightness.

Real-World Example: IR in Action

I tested my Arlo Pro 4 in my backyard, which has a 30-foot stretch of grass leading to the fence. At 10 p.m., I walked the path while recording. Here’s what happened:

• 0-15 feet: Crisp black-and-white footage. I could read a license plate on my car.
• 15-25 feet: Slightly grainy, but still clear. I could identify a person’s clothing and movements.
• 25-30 feet: Blurry, but motion was still detectable. A person’s silhouette was visible.

Conclusion: Arlo’s 25-foot IR range is accurate, but for full clarity, keep subjects within 20 feet.

Optimizing Arlo Cameras for the Best IR Performance

Positioning: Where to Place Your Camera

Even the best IR tech fails if the camera is poorly positioned. Follow these tips:

• Height: Mount 7-9 feet high. Too low, and IR light hits the ground, creating shadows. Too high, and faces become hard to see.
• Angle: Point the camera slightly downward (15-30 degrees). This ensures IR light hits the ground and reflects upward, illuminating faces and objects.
• Clear Line of Sight: Avoid placing cameras behind trees, bushes, or glass. IR light scatters through obstacles, reducing range.
• Distance: For optimal clarity, keep the area of interest within 80% of the camera’s IR range. For a 25-foot range, focus on the first 20 feet.

Adjusting Settings in the Arlo App

The Arlo app lets you fine-tune IR performance:

• Night Vision Mode: Choose between Auto (switches to IR at dusk), On (IR always on), or Off (for color night vision with spotlight).
• Motion Detection Sensitivity: Lower sensitivity in areas with lots of IR-reflective objects (e.g., white walls, shiny cars) to reduce false alerts.
• Activity Zones: Define zones where motion should trigger recording. Exclude areas like trees or roads to focus IR on high-risk spots.

Pro Tip: In the app, enable “Smart Alerts” (requires Arlo Secure subscription). This uses AI to distinguish between people, vehicles, and animals, reducing false alarms.

Boosting IR with Accessories

If your IR range feels limited, try these:

• Arlo Solar Panel: Keeps batteries charged, ensuring full IR brightness (no power-saving dimming).
• External IR Illuminators: Add standalone IR floodlights (like the Arlo IR Extender) to extend range. Mount them 10-15 feet from the camera.
• Reflective Surfaces: Place white stones or a light-colored mat near the camera. These reflect IR light, improving visibility in shadows.

Limitations and Workarounds for Arlo’s IR Night Vision

Common Challenges You Might Face

Even with great tech, IR has limitations:

• Glare from Glass: Mounting behind a window? IR light reflects off the glass, creating a bright spot. Solution: Mount the camera outside or use a camera with a wide-angle lens to avoid glass.
• Fog/Rain: Moisture scatters IR light, reducing clarity. Solution: Use a camera with a higher IR count (e.g., Ultra 2) or add a weather shield.
• Overexposure: If someone walks right up to the camera, their face may look “washed out.” Solution: Enable “Auto IR” in settings—it dims the LEDs up close.
• Battery Drain: IR uses power. A camera with low batteries may dim IR to save energy. Solution: Use solar panels or recharge frequently.

When to Use Color Night Vision Instead

Some Arlo models (like Pro 5 and Ultra 2) offer color night vision via a built-in spotlight. Use this when:

• You need to identify colors (e.g., a car, clothing, or a package).
• The area is already well-lit (e.g., a porch with a light).
• You’re okay with a visible light turning on (not ideal for stealth).

For example, I use color night vision for my front door camera. The spotlight activates when someone approaches, and I can see the color of their jacket or car. For my backyard, I stick with IR to avoid alerting intruders.

Final Thoughts: Are Arlo Cameras IR Worth It?

So, are Arlo cameras IR? Absolutely—and they do it well. From the budget-friendly Essential series to the high-end Ultra 2, Arlo’s IR night vision is reliable, adaptable, and designed for real-world use. The technology works quietly in the background, giving you peace of mind without blinding lights or complicated setups.

But here’s the thing: no security camera is perfect. IR has limits—range, weather, and positioning matter. The key is understanding your needs. If you have a small porch, an Essential Outdoor with 20-foot IR is plenty. For a sprawling backyard, invest in an Ultra 2 with 30-foot range and 940nm stealth IR. And if you want color footage, pair a Pro 5 with a spotlight for those critical moments.

My advice? Don’t just buy a camera—test it. Set it up, check the footage at night, and tweak the settings. Use the Arlo app to adjust sensitivity, activity zones, and IR modes. Add accessories like solar panels or external illuminators if needed. And remember: the best security system is one you understand and trust.

At the end of the day, Arlo’s IR technology isn’t about flashy specs—it’s about seeing what matters, when it matters. Whether it’s a raccoon, a delivery person, or an uninvited guest, you’ll be ready. Because when the sun goes down, your camera shouldn’t.
