Why This Matters / Understanding the Problem

Ever checked your Arlo camera feed only to see a blurry, fogged-up lens? You’re not alone. It’s frustrating when your security camera—meant to give you peace of mind—ends up giving you a foggy mess instead.

Fogging happens when moisture builds up inside the camera housing, usually due to temperature changes, humidity, or poor sealing. In 2026, with more people relying on outdoor Arlo cameras for 24/7 security, knowing how to keep Arlo cameras from fogging up in 2026 is more important than ever.

Think about it: You install a sleek Arlo Ultra 2 or a trusty Arlo Pro 5, and after a rainy night or a cold morning, the lens is covered in condensation. That’s not just annoying—it can compromise your home’s security. You might miss a delivery, a visitor, or worse, a suspicious person.

But here’s the good news: Fogging is preventable. And it doesn’t require fancy gear or technical wizardry. With a few smart habits and simple fixes, you can keep your Arlo camera’s lens crystal clear, rain or shine.

Whether you’re dealing with morning dew, coastal humidity, or sudden winter chills, this guide will walk you through how to keep Arlo cameras from fogging up in 2026—step by step, with real-world tips from someone who’s been there.

What You Need

Before we dive into the steps, let’s talk about what you’ll need. The beauty of this fix? Most of it uses stuff you already have or can grab for under $20.

• Silica gel packets (the kind that come in shoeboxes or electronics packaging)
• Waterproof silicone sealant (like GE Silicone II)
• Microfiber cloth (for cleaning the lens)
• Isopropyl alcohol (70% or higher) and cotton swabs
• Small zip-top plastic bag (optional, for temporary storage)
• Heat gun or hairdryer (for drying out moisture)
• Arlo camera housing tool (or a small flathead screwdriver, if needed)
• Desiccant packs or reusable silica gel canisters (optional, but helpful)

You don’t need to be a DIY expert. Most of these items are household staples. And if you’ve ever opened a new pair of headphones or a phone case, you’ve probably got a silica gel packet lying around.

The key is being proactive. Once fogging starts, it’s harder to fix. So let’s get ahead of it.

Step-by-Step Guide to How to Keep Arlo Cameras from Fogging Up in 2026

Step 1: Check the Camera Housing for Gaps or Cracks

Start by giving your Arlo camera a close inspection. Look at the seams, the lens bezel, and the charging port cover. Even a tiny crack or loose seal can let in moisture.

If you see any gaps, especially around the lens or battery compartment, that’s likely the entry point. Arlo cameras are designed to be weather-resistant (IP65 or IP66 rated), but over time, seals can degrade—especially if the camera’s been exposed to extreme heat or cold.

Use a flashlight to check for hairline cracks. If you find any, don’t panic. We’ll fix them in Step 3. For now, just note the location.

Personal tip: I once had a camera fog up every morning in my backyard. Turns out, the charging port cover wasn’t fully snapped in. A quick press fixed it. Always check the little things!

Step 2: Clean the Lens and Housing Thoroughly

Before sealing anything, make sure the inside of the camera is dry and clean. Use a microfiber cloth to wipe the lens gently. Then, use a cotton swab dipped in isopropyl alcohol to clean the edges and seals.

This removes any dust, grime, or residue that could trap moisture. Alcohol evaporates quickly, so it won’t leave behind water spots.

If your camera has visible moisture inside, don’t skip this step. You need to dry it out completely before sealing.

To dry it:

• Remove the battery (if possible).
• Place the camera in a warm, dry spot (like near a dehumidifier or in a sunny window).
• Leave it for 24–48 hours. Avoid direct heat—no ovens or microwaves!

For faster drying, use a hairdryer on the cool setting. Hold it at least 12 inches away and move it around to avoid overheating the plastic.

Step 3: Add a Desiccant Inside the Camera Housing

This is where the magic happens. Desiccants absorb moisture and help maintain a dry interior. Silica gel packets are perfect for this.

Here’s how to do it:

1. Open the camera housing (follow Arlo’s official guide for your model).
2. Place 2–3 silica gel packets inside the housing, away from the lens and electronics. Don’t let them touch any circuitry.
3. Reassemble the camera carefully.

Pro tip: Use reusable silica gel canisters (like DampRid) if you want something more durable. They change color when saturated, so you know when to recharge them in the oven.

For extra protection, you can also place a small desiccant pack inside the charging port cover or near the battery compartment.

Warning: Never use rice! It’s a myth. Rice absorbs moisture slowly and can leave starch residue, which is worse than the fog. Stick to silica gel.

Step 4: Seal the Housing with Waterproof Silicone

Now, let’s make sure no new moisture gets in. Use a small bead of waterproof silicone sealant around the edges of the camera housing, especially:

• The lens bezel
• The battery compartment
• The charging port cover
• Any seams or joints

Apply a thin, even line—don’t glob it on. You want a watertight seal, not a mess. Use a toothpick or cotton swab to smooth it out.

Let the silicone cure for 24 hours before exposing the camera to rain or moisture. Most silicone sealants are rain-ready after 2–4 hours, but full cure takes a day.

This step is crucial for how to keep Arlo cameras from fogging up in 2026, especially if you live in a humid or rainy climate.

Step 5: Install the Camera in a Dry, Sheltered Location

Even the best-sealed camera can fog up if it’s constantly exposed to rain, snow, or direct sun. Position your Arlo camera under an eave, porch, or awning.

Avoid:

• Direct rainfall (like on a post or tree branch)
• Sprinkler spray
• South-facing walls (they get the most sun and heat)
• Low-lying areas where water pools

Instead, aim for:

• Under a roof overhang
• Inside a covered entryway
• Near a wall with a slight angle (to shed water)

If you can’t avoid exposure, consider a weatherproof camera housing or a 3D-printed rain shield (available on Etsy or Thingiverse).

Step 6: Use a Heated Camera Mount (Optional but Effective)

In cold climates, temperature swings cause condensation. A heated camera mount can prevent this by keeping the camera at a stable temperature.

These mounts plug into a nearby outlet and gently warm the camera housing. They’re especially useful in winter or in areas with frequent frost.

Arlo doesn’t make one, but third-party options like the CamGuard Pro or Outdoor Heated Camera Cover work well with Arlo models.

Just make sure the mount is compatible with your Arlo camera and doesn’t block the lens or motion sensor.

Step 7: Monitor and Maintain Every 3–6 Months

Fogging isn’t a “set it and forget it” problem. Check your cameras every few months, especially after extreme weather.

What to do during maintenance:

• Inspect seals for cracks or wear
• Replace silica gel packets (or recharge them)
• Clean the lens with a microfiber cloth
• Check for condensation inside the housing

If you notice fogging starting again, repeat Steps 1–4. Prevention is always easier than fixing a fogged-up camera.

This routine care is a big part of how to keep Arlo cameras from fogging up in 2026—and beyond.

Pro Tips & Common Mistakes to Avoid

Pro Tip #1: Use the “Two-Pack” Silica Gel Trick

Instead of one large packet, use two smaller ones. This spreads the desiccant more evenly and reduces the risk of one blocking airflow.

I learned this the hard way. I once used one big packet, and it got stuck near the lens. Two small ones? No problem.

Pro Tip #2: Recharge Silica Gel Packets in the Oven

Don’t throw them away when they’re saturated. Spread the beads on a baking sheet and bake at 200°F (93°C) for 2–3 hours. They’ll turn blue (or clear) and be ready to use again.

Save money and reduce waste—win-win.

Pro Tip #3: Avoid Over-Sealing

While sealing is good, don’t cover the lens or vents. Arlo cameras need some airflow to regulate temperature. Blocking vents can actually increase condensation.

Only seal the seams and housing edges. Leave the lens and any labeled vents untouched.

Common Mistake #1: Ignoring the Charging Port

The charging port is a prime entry point for moisture. Make sure the cover is fully closed and sealed. A dab of silicone around the edge helps, but don’t glue it shut!

I once saw a friend’s camera fog up because the charging port cover was loose. A 5-second fix saved his camera.

Common Mistake #2: Using the Wrong Sealant

Not all silicones are created equal. Use a waterproof, non-corrosive silicone like GE Silicone II. Avoid construction-grade sealants—they can damage plastic and electronics.

Common Mistake #3: Skipping the Dry-Out Step

If your camera is already fogged, you must dry it out before sealing. Sealing a wet camera traps the moisture inside, making the problem worse.

Patience pays off. Wait the full 24–48 hours. Your future self will thank you.

FAQs About How to Keep Arlo Cameras from Fogging Up in 2026

Q: Can I use rice to dry out my fogged Arlo camera?

No, please don’t. Rice is a myth. It absorbs moisture slowly and can leave starch residue, which attracts more moisture. Use silica gel or a desiccant pack instead. They’re faster, safer, and more effective.

Q: Why does my Arlo camera fog up only in the morning?

That’s a classic sign of temperature shock. Overnight, the camera cools down, and when the sun hits it in the morning, the warm, moist air condenses on the cold lens. This is common in humid climates. A desiccant inside the housing and a sheltered location help prevent it.

Q: Are Arlo cameras waterproof?

Arlo cameras are weather-resistant (IP65 or IP66 rated), not fully waterproof. That means they can handle rain and splashes, but not submersion or constant high-pressure water. Proper sealing and placement are key to long-term performance.

Q: Can I open my Arlo camera without voiding the warranty?

It depends. Arlo’s warranty covers defects, not user modifications. If you open the housing and damage something, it might void the warranty. But if you’re careful (and don’t break anything), you’re probably okay. Just document your steps and keep the original seals.

For newer models like the Arlo Pro 5 or Ultra 2, consider using external solutions (like a rain shield) instead of opening the housing.

Q: How often should I replace silica gel packets?

It depends on humidity. In dry climates, every 6–12 months. In humid or rainy areas, every 3–6 months. If the packets feel warm or clump, replace them sooner. Or, use reusable canisters that you can recharge.

Q: What if my camera still fogs up after all these steps?

It’s rare, but possible. Check for:

• Internal damage (like a cracked lens)
• Faulty seals from the factory
• Extreme conditions (like a hurricane)

If everything looks fine, contact Arlo support. They may replace the unit under warranty.

Q: Can I use a hairdryer to dry my camera?

Yes, but only on the cool setting. High heat can warp the plastic or damage electronics. Hold it at least 12 inches away and move it constantly. Never use a heat gun or oven.
