Can Rain and Thunderstorm Affect My Arlo Cameras Performance

Yes, rain and thunderstorms can temporarily affect your Arlo camera’s performance, especially if water accumulates on the lens or the device isn’t fully weatherproof. Heavy downpours or electrical interference from lightning may disrupt Wi-Fi signals, cause false motion alerts, or blur footage—but most Arlo models are designed to withstand typical weather conditions when properly installed.

Key Takeaways

• Rain can disrupt signals: Heavy downpours may weaken Wi-Fi connectivity for outdoor Arlo cameras.
• Use weatherproof models: Opt for Arlo’s IP65+ rated cameras for reliable storm resistance.
• Position cameras wisely: Install under eaves or covers to minimize direct rain exposure.
• Check power sources: Ensure battery-powered units are charged; storms can drain power faster.
• Night vision may suffer: Heavy rain or fog can reduce infrared visibility—test post-storm.
• Firmware updates help: Keep cameras updated to fix weather-related performance bugs.

Can Rain and Thunderstorm Affect My Arlo Cameras Performance

It’s a quiet Tuesday evening. You’ve just settled on the couch with a warm cup of tea, ready to unwind. The sky outside is still clear, but a quick glance at the weather app shows a thunderstorm rolling in. You glance at your Arlo camera’s live feed—everything looks good. But then the rain starts. Heavy drops patter against the window, and the sky flashes with lightning. You notice something odd: the camera feed flickers, then goes blurry. A few minutes later, the app notifies you that the camera is offline. Sound familiar?

You’re not alone. Many Arlo camera owners have experienced similar hiccups during storms. Whether you’re using the Arlo Pro 4, Arlo Ultra, or even the older Arlo Pro 2, weather—especially rain and thunderstorms—can impact performance. But how much? Is it a temporary glitch or a sign of deeper issues? And more importantly, what can you do to protect your investment and keep your home secure, no matter the weather? In this post, we’ll dive into the real-world effects of rain and thunderstorms on Arlo cameras, backed by user experiences, technical insights, and practical solutions.

How Rain Affects Arlo Camera Performance

Rain is more than just a nuisance. It can directly and indirectly influence how your Arlo cameras function. While Arlo markets its outdoor cameras as “weather-resistant” or “weatherproof,” there’s a fine line between resistance and immunity. Let’s break down the ways rain can impact your system.

1. Water Intrusion and Moisture Buildup

Even with an IP65 or IP66 rating, which means protection against dust and low-pressure water jets, prolonged exposure to heavy rain can cause issues. Think of it like a tent in a downpour: the outer layer might repel water, but if it’s wind-driven rain at a 45-degree angle, moisture can seep in through tiny gaps or seals.

• Example: A user in Seattle reported that after a week of constant rain, their Arlo Pro 4 developed a foggy lens. The moisture wasn’t from a cracked housing but from condensation inside the lens due to temperature shifts.
• Tip: Regularly inspect the camera housing for cracks, warping, or loose seals. Use a soft, dry cloth to wipe down the lens after heavy rain to prevent water spots and fogging.

Moisture inside the lens can blur footage, trigger false motion alerts (due to water droplets moving in the field of view), or even damage internal circuitry over time.

2. Reduced Night Vision and IR Performance

Raindrops on the lens scatter infrared light, which is used for night vision. This creates “ghost spots” or a hazy effect in dark footage. In heavy rain, the IR beams bounce off water droplets, reducing the effective range of night vision from 30 feet to just 10–15 feet.

• Tip: Install a small overhang or awning above the camera to shield it from direct rain. Even a 6-inch extension can make a big difference. Alternatively, use a third-party rain shield (many are Arlo-compatible).
• Pro Insight: Arlo’s SmartHub or Arlo Base Station can help stabilize the connection during weather events, but it won’t fix lens fogging.

3. Signal Interference from Wet Surfaces

Water is a natural conductor of electricity. When rain soaks the ground or accumulates on surfaces, it can subtly alter the electromagnetic environment. This may cause Wi-Fi signal degradation, especially if your camera relies on a 2.4 GHz band (which is more prone to interference than 5 GHz).

• Example: A user in Florida noticed their Arlo camera dropped from “Excellent” to “Fair” signal strength during a storm, even though the router was indoors and only 30 feet away.
• Tip: Use a Wi-Fi analyzer app (like NetSpot or WiFi Analyzer) to check signal strength during and after rain. If drops occur, consider relocating the base station or adding a Wi-Fi extender.

Thunderstorms and Electrical Risks: Lightning, Power Surges, and More

Thunderstorms bring more than just rain. They introduce a suite of electrical dangers that can compromise your Arlo system. Here’s what you need to know.

1. Lightning Strikes and Power Surges

Even if lightning doesn’t hit your camera directly, it can induce voltage surges in nearby power lines, Ethernet cables, or even Wi-Fi signals. Arlo’s outdoor cameras are battery-powered, but if you’re using a wired power adapter (like the Arlo Solar Panel or AC adapter), that creates a direct path for surges.

• Real Story: A homeowner in Texas lost two Arlo Pro 4 cameras during a storm. The cause? A lightning strike 500 feet away sent a surge through the outdoor outlet where the solar panel was plugged in. The base station, connected via Ethernet, also failed.
• Tip: Always use a surge protector for any wired Arlo accessories. A $20 surge protector can save you hundreds in replacement costs. For solar panels, unplug during severe storms.

2. Electromagnetic Interference (EMI)

Thunderstorms generate intense electromagnetic fields. These can disrupt wireless communication, causing:

• Camera disconnections
• Delayed motion alerts
• Corrupted video uploads

While Arlo uses 2.4 GHz and 5 GHz bands (with 5 GHz being more stable), EMI from lightning can still overwhelm receivers temporarily.

• Tip: During storms, switch to a 5 GHz connection if your camera supports it (Arlo Pro 4, Ultra 2). Keep the base station away from metal objects or appliances that amplify EMI.
• Note: Battery-powered Arlo cameras are less vulnerable to EMI than wired ones, but signal strength still drops during storms.

3. Wind-Driven Rain and Physical Damage

Thunderstorms often come with high winds. Rain blown sideways can hit the camera at angles that bypass standard seals. Over time, this can erode gaskets or loosen mounts.

• Example: A user in Oklahoma found their Arlo camera dangling by one screw after a tornado warning. The wind had loosened the mounting bracket, and the camera swung like a pendulum, damaging the housing.
• Tip: Use stainless steel screws and check mounts monthly. For high-wind areas, consider a recessed mount or protective housing.

How Arlo Cameras Are Designed for Weather (And Where They Fall Short)

Arlo doesn’t make its cameras weatherproof by accident. Let’s explore the design choices—and their limitations.

1. IP Ratings Explained

Most Arlo outdoor cameras have an IP65 or IP66 rating:

• IP65: Dust-tight, protected against low-pressure water jets (e.g., garden hose)
• IP66: Dust-tight, protected against high-pressure water jets (e.g., heavy rain)

But these tests are done in controlled labs. Real-world conditions (like wind-driven rain or temperature swings) aren’t replicated.

• Limitation: IP ratings don’t account for prolonged exposure. A camera might pass a 3-minute water jet test but fail after a 6-hour storm.
• User Feedback: 32% of surveyed Arlo users reported moisture issues after 3+ days of rain, according to a 2023 community poll on Reddit’s r/Arlo.

2. Battery and Charging in Wet Conditions

Arlo’s battery-powered design is a double-edged sword. On one hand, no wires mean no surge risk. On the other, cold and wet conditions drain batteries faster.

• Data: Arlo states batteries last 3–6 months. In real-world tests, users in rainy climates report 2–3 months, especially in winter.
• Tip: Use lithium batteries (not alkaline) for better cold-weather performance. Charge batteries indoors during storms to avoid condensation.

3. The Role of the Base Station/SmartHub

The base station acts as a Wi-Fi bridge and local storage hub. During storms, it’s often more stable than individual cameras.

• Advantage: Even if a camera disconnects, the base station can store footage locally (if you have a USB drive).
• Weakness: If the base station loses power (e.g., power outage), all connected cameras go offline. Use a UPS (uninterruptible power supply) for critical setups.

Practical Tips to Protect Your Arlo Cameras in Rain and Thunderstorms

Now that we’ve covered the risks, here’s how to bulletproof your system. These tips are based on user reports, expert advice, and real-world testing.

1. Optimize Camera Placement

• Under Eaves: Mount cameras under roof overhangs or awnings. This reduces direct rain exposure.
• Angle Downward: Tilt the camera slightly downward (10–15 degrees). This helps rain run off the lens and reduces pooling.
• Use Rain Shields: Third-party shields (like the Arlo Rain Guard) cost $15–$25 and extend the camera’s lifespan.

2. Strengthen Your Wi-Fi Network

• Upgrade to 5 GHz: If your camera supports it, use 5 GHz for less interference.
• Use Wi-Fi Extenders: Place extenders outdoors (in weatherproof enclosures) to maintain signal strength.
• Test Signal Regularly: Use a free app like WiFi Analyzer to spot weak spots.

3. Prepare for Power Outages and Surges

• Surge Protectors: Use for base stations, solar panels, or wired cameras.
• UPS for Base Station: A $50 UPS can keep your base station running for 1–2 hours during outages.
• Solar Panel Backup: If you use solar, ensure the panel is angled to shed rain and debris.

4. Maintain Your Cameras

• Monthly Checkups: Inspect seals, lenses, and mounts. Clean with a microfiber cloth.
• Firmware Updates: Arlo often releases updates to improve weather resistance. Enable auto-updates.
• Battery Care: Store spare batteries in a dry, cool place. Rotate them every 3 months.

5. Monitor and Adapt

• Use Weather Alerts: Link your Arlo app to weather apps (like AccuWeather) to get storm warnings.
• Review Footage After Storms: Check for blurry or missing clips. This helps identify weak spots.
• Community Forums: Join r/Arlo or Arlo’s official forum to learn from other users’ experiences.
