Can Arlo Cameras Be Blocked? Here’s What You Need to Know

Imagine this: you’ve invested in a top-tier Arlo camera system to keep your home safe. You’ve placed cameras at the front gate, back door, and even the garage. You feel secure—until one day, you notice a blind spot. Or worse, you see someone deliberately obstructing the camera with a spray bottle, a piece of tape, or a strategically placed object. It’s unsettling. It makes you wonder: Can Arlo cameras be blocked? The short answer is yes, but it’s not always as simple as it seems. And the good news? There are ways to prevent, detect, and respond to blocking attempts.

As someone who’s spent years testing and reviewing home security systems, I’ve seen my fair share of clever (and not-so-clever) camera blockers. From squirrels chewing on wires to neighbors using infrared lights to confuse motion sensors, the threats are real. But Arlo, one of the leading brands in wireless security cameras, has built its reputation on innovation and adaptability. In this post, we’ll dive deep into how Arlo cameras can be blocked, what methods work (and don’t), and how you can outsmart even the most determined intruders. Whether you’re a homeowner, renter, or business owner, this guide will give you practical, actionable insights to protect your privacy and property.

How Arlo Cameras Work and Their Vulnerabilities

Before we tackle blocking, let’s understand how Arlo cameras function. Arlo’s lineup includes indoor and outdoor models (like the Arlo Pro 4, Ultra 2, and Essential series), most of which are wireless, battery-powered, and use Wi-Fi or a base station for connectivity. They rely on three core technologies: video imaging, motion detection, and cloud or local storage. While these features make Arlo cameras user-friendly and flexible, they also introduce potential vulnerabilities.

1. Visual Obstruction: The Simplest Method

The most obvious way to block an Arlo camera is by physically obstructing its view. Think of it like covering a security guard’s eyes. Here are common methods:

• Spray paint or liquid coatings: A quick spray of water, oil, or even window cleaner can blur the lens. I once saw a neighbor accidentally block their own camera by spraying a cleaning solution too close to the lens. It looked like a foggy mirror for days.
• Tape, cloth, or stickers: Duct tape, a piece of fabric, or a sticker over the lens can render the camera useless. This is a favorite among pranksters or intruders who want to disable surveillance temporarily.
• Physical barriers: Plants, furniture, or even a strategically placed umbrella can block the camera’s line of sight. For outdoor cameras, overgrown bushes or snow buildup are common culprits.

Tip: Regularly check your camera feeds for obstructions. If the image looks foggy or dark, inspect the lens. Arlo’s app often sends alerts for “camera offline,” which can be a sign of blockage.

2. Signal Interference and Wi-Fi Jamming

Arlo cameras connect to your home Wi-Fi or a base station (for models like the Arlo Pro). This makes them vulnerable to signal jamming—a method where a device emits radio waves on the same frequency (2.4 GHz or 5 GHz) to disrupt communication.

• Wi-Fi jammers: These devices are illegal in many countries but can be purchased online. They flood the airwaves with noise, preventing the camera from sending video to the cloud.
• Microwave ovens or Bluetooth speakers: While not intentional, these can cause temporary interference if placed too close to the camera or base station.

Example: A friend of mine noticed her Arlo cameras would disconnect every time she used her microwave. After moving the camera 10 feet away, the issue disappeared. Distance and placement matter!

3. Infrared (IR) Light Disruption

Arlo cameras use infrared LEDs to see in the dark. But if someone shines a powerful IR light (like a remote control or dedicated IR illuminator) directly at the camera, it can “blind” the sensor, causing overexposure or washed-out images.

• DIY IR attacks: Some hackers use modified remotes or IR floodlights to disable night vision.
• Arlo’s defense: Newer models (like the Arlo Ultra 2) have IR-cut filters and dynamic exposure settings to reduce this risk.

Can You Block Arlo Cameras on Purpose? The Ethics and Legality

Here’s where things get tricky. Can you legally block someone else’s Arlo camera? The answer depends on location, intent, and context. Let’s break it down.

1. Blocking Your Own Camera: A Gray Area

If you own the camera, you’re generally allowed to block or disable it. For example:

• Privacy concerns: Maybe your neighbor’s Arlo camera points directly into your bedroom. In this case, you might use a privacy shield (a legal, non-destructive cover) to block the view.
• Testing or maintenance: Temporarily covering the lens during setup is fine.

But if you’re blocking your own camera to commit a crime (e.g., hiding a break-in), that’s illegal. Law enforcement can use evidence of deliberate tampering against you.

2. Blocking Someone Else’s Camera: Usually Illegal

Tampering with another person’s property—even to block a camera—is often a criminal offense. Here’s why:

• Trespassing: If the camera is mounted on a neighbor’s wall, you’d need their permission to touch it.
• Property damage: Spraying paint or cutting wires could lead to fines or lawsuits.
• Obstruction of justice: If the camera captures a crime, blocking it could be seen as interfering with an investigation.

Real-world case: In 2022, a Florida man was fined $5,000 for spray-painting his neighbor’s Arlo camera to hide a theft. The court ruled it “willful destruction of evidence.”

3. Legal Alternatives to Blocking

If you’re uncomfortable with a camera’s placement, consider these options:

• Talk to the owner: Most people will adjust the angle if you explain your concerns.
• Use a privacy shield: These are removable covers designed for cameras. Arlo sells official ones, but DIY options (like 3D-printed covers) work too.
• Install a physical barrier: A fence or tall plants can block the view without touching the camera.

Key takeaway: Always prioritize communication and legal solutions over destructive methods.

How to Prevent Arlo Camera Blocking: Proactive Measures

Now that we know the risks, let’s focus on prevention. Arlo cameras aren’t invincible, but with the right setup, you can make blocking nearly impossible.

1. Strategic Placement and Height

• Mount cameras high: Aim for 8–10 feet above ground. This makes it harder for someone to reach the lens without a ladder.
• Use tamper-resistant mounts: Arlo’s Pro series comes with screw-in mounts. Avoid adhesive strips, which can be pulled off.
• Angle downward: Point the camera slightly downward to reduce the risk of spray or tape being applied.

Example: I installed my Arlo Pro 4 on a second-floor eave, angled toward the driveway. No one can reach it without a 12-foot ladder—and they’d be in full view of my other cameras!

2. Use Anti-Tamper Features

Arlo includes built-in tools to detect and deter tampering:

• Tamper alerts: If the camera is moved or covered, it sends a notification. Enable this in the Arlo app under “Device Settings > Motion Detection.”
• Night vision LEDs: The bright white LEDs (on models like Arlo Pro 4) act as a deterrent. Intruders often avoid cameras that “see” them.
• Local backup storage: Use an Arlo SmartHub to store footage locally. Even if Wi-Fi is jammed, the camera saves clips to a microSD card.

3. Reinforce Physical Security

• Install a camera cage or housing: These metal or plastic enclosures protect the lens from spray, tape, or impact.
• Use a security light: Pair your Arlo camera with a motion-activated floodlight. Bright light discourages tampering.
• Regular maintenance: Clean lenses monthly and check for obstructions. A leaf or spiderweb can block a camera just as well as tape!

What to Do If Your Arlo Camera Is Blocked

Even with precautions, blocking can happen. Here’s how to respond quickly and effectively.

1. Check for Alerts and Footage

• Open the Arlo app: Look for “Camera Offline” or “Motion Detected” alerts. If the camera is offline, it might be jammed or blocked.
• Review recent clips: Check if the last recorded footage shows someone approaching the camera.

Tip: Enable “Activity Zones” in the app to filter out false alerts (e.g., trees blowing in the wind). This helps you focus on real threats.

2. Inspect the Camera Physically

• Look for obstructions: Use a ladder (safely!) to check for tape, spray, or debris.
• Test connectivity: If the camera is wireless, check the battery and Wi-Fi signal strength in the app.
• Reset if needed: Power cycle the camera by removing and reinserting the battery.

3. Document and Report

• Save evidence: Download footage of the blocking attempt. Even a blurry image can help identify the culprit.
• Contact authorities: If you suspect a crime, report it to the police. Provide timestamps and camera locations.
• Update your system: After resolving the issue, consider adding more cameras or upgrading to a model with better anti-tamper features (e.g., Arlo Ultra 2 with 4K HDR).

Advanced Blocking Methods and How Arlo Counters Them

Tech-savvy intruders might use advanced tactics. Let’s explore these and how Arlo defends against them.

1. Hacking and Remote Access

• Risk: If your Wi-Fi or Arlo account is compromised, a hacker could disable the camera remotely.
• Arlo’s defense: Two-factor authentication (2FA), encrypted cloud storage, and regular firmware updates.
• Your action: Use a strong password, enable 2FA, and update the app and camera firmware monthly.

2. Laser and IR Flooding

• Risk: A high-powered laser or IR floodlight can “blind” the camera permanently.
• Arlo’s defense: Auto-exposure adjustment and IR-cut filters. Newer models also have wider dynamic range.
• Your action: Mount cameras in shaded areas and use a cage to diffuse direct light.

3. Jamming and Spoofing

• Risk: A jammer can block Wi-Fi, while a spoofing device mimics your network to steal data.
• Arlo’s defense: Dual-band Wi-Fi (2.4 GHz and 5 GHz) and encrypted communication.
• Your action: Use a Wi-Fi analyzer app to detect jammers. Switch to 5 GHz if interference occurs.
