Smart Doorbell and Home Camera Hacking: How to Lock Down Your Connected Devices
Key Takeaways
Your doorbell camera is supposed to make you feel safer. But a security researcher sitting nearly 3,000 miles away recently pulled live images from a journalist's own backyard camera, without her knowing, thanks to a flaw in the doorbell's firmware. She set it up herself. She thought she was protected.
That's the quiet problem with smart doorbells and home cameras: they're marketed as security devices, but when they're not properly configured, they can become the vulnerability. And it's not just one rogue brand. Budget doorbells sold on Amazon, Walmart, and Temu have been caught transmitting Wi-Fi passwords in plain text, skipping basic encryption, and using default credentials that anyone can guess.
This guide breaks down exactly how these attacks happen, which devices are most exposed, and what you can do right now to close the gaps.
How do hackers get into smart doorbells and home cameras?
Most successful attacks on home cameras don't look like the hacking scenes in movies. There's no one cracking code in the dark. The reality is far more ordinary, and fixable.
Weak or default passwords are the most common entry point. Many budget smart doorbells ship with the same default username and password across every unit. If you never change them, anyone who knows that device's default credentials, information that's often publicly listed, can log in. It takes minutes.
Unencrypted data transmission is the second big problem. Consumer watchdog Which? tested 11 smart doorbell models and found that some sent home network names and passwords to remote servers without any encryption, including a best-selling model on Amazon UK at the time. BBC News reported that two of the devices tested could be manipulated to steal network credentials and then attack other devices on the same home network.
Flawed firmware from no-name brands is where things get especially concerning. A Consumer Reports investigation found that multiple doorbell cameras sold under different brand names (Eken, Tuck, Fishbot, Rakeblue) were all controlled through the same mobile app and shared the same critical vulnerabilities. A researcher hacked into one from nearly 3,000 miles away and retrieved real images from a colleague's home.
Credential stuffing is a tactic where attackers use usernames and passwords leaked from other data breaches to try to access your camera account. If you use the same password across multiple accounts, one breach anywhere can open up your doorbell feed everywhere.
Which devices are most at risk?
The honest answer: the cheapest ones.
Established brands like Ring, Google Nest, and Arlo have security teams, regular firmware updates, and support for two-factor authentication. That doesn't make them bulletproof, but it puts them in a very different category from the flood of budget devices manufactured under multiple brand aliases and sold through third-party marketplace listings.
Consumer Reports found at least 10 seemingly identical doorbell cameras sold under different brand names, all sharing the same vulnerable app, the same weak security architecture, and the same manufacturer. The FCC later proposed a $734,872 fine against Eken, one of the manufacturers behind these devices.
The broader pattern holds across all IoT devices. According to the NETGEAR and Bitdefender 2024 IoT Security Landscape Report, home network devices now face an average of 10 attacks per day. The report analyzed 50 million IoT devices across 3.8 million homes worldwide. Smart devices that rarely receive firmware updates, and budget doorbells are notorious for this, stay exposed long after manufacturers patch known flaws in newer models.
IoT cyberattacks jumped 124% in 2024, according to SonicWall's 2025 Annual Cyber Threat Report via CNET, with SonicWall stopping more than 17 million attacks on IP cameras in that year alone.
What can attackers actually do if they get in?
Access to your doorbell camera is access to your life's rhythms.
An attacker who controls your front camera knows when you leave the house, when you come home, when you have visitors, and when the house is empty. For people facing threats from a stalker or an abusive ex-partner, that level of visibility is genuinely dangerous. Consumer Reports specifically flagged this risk in their investigation, a compromised camera can tell a dangerous person everything they need to plan and act.
Beyond surveillance, a hacked doorbell that shares your home network can become a launchpad. If the device can be used to capture your Wi-Fi credentials, attackers can potentially reach other devices on the same network: laptops, phones, smart locks, baby monitors.
How to lock down your smart doorbell and home cameras
The good news: the steps that actually work aren't complicated. Most people skip them because setup flows don't emphasize security, but none of these take more than a few minutes.
Change the default password immediately. Never leave the factory default in place. Use a password that's unique to this device, not something you use for email or any other account. A random string of 16 or more characters is better than any memorable phrase.
Turn on two-factor authentication (2FA). Ring, Google Nest, and most reputable camera brands support 2FA. When it's on, someone who has your password still can't get in without a second verification step. Ring's support pages walk through setup directly in the app. Make this the first thing you do after changing your password.
Keep firmware updated. Firmware updates fix known vulnerabilities. Budget brands often stop issuing them entirely after a few months. Check your camera's app regularly for update prompts, and if a device hasn't received an update in over a year, treat that as a warning sign.
Put your cameras on a separate Wi-Fi network. Most modern routers let you create a guest network or a dedicated IoT network. Putting your doorbell and cameras there means that even if one device is compromised, the attacker can't easily reach your laptop, phone, or other sensitive devices on the main network.
Buy from established brands with active security support. The price difference between a $25 no-name doorbell and a $100 Ring or Nest isn't just about build quality. It's about whether someone is patching vulnerabilities when researchers find them. The FCC fine against Eken underlines what happens when no one is.
Review who has account access. Doorbell camera apps often let you share access with family members. Check which accounts have active access and remove anyone who shouldn't still have it. Former roommates, ex-partners, or anyone you shared access with during a different chapter of your life can retain live camera access until you revoke it manually.
Check your router's settings. Disable UPnP (Universal Plug and Play) on your router if you don't need it. UPnP lets devices on your network open ports automatically, which can expose your camera to the internet without your knowledge.
A quick security checklist
Before you close this article, run through these:
- Default password changed to something unique
- Two-factor authentication turned on in the camera app
- Firmware updated to the latest version
- Camera connected to a separate IoT or guest Wi-Fi network
- Account access reviewed and unnecessary users removed
- UPnP disabled on your home router
If you can check all six, your doorbell camera is meaningfully more secure than the vast majority of devices out there.
Conclusion
Smart doorbells and home cameras are genuinely useful. They let you see who's at your door, check on your property remotely, and keep a record of what happens outside your home. None of that value disappears because of security risks, it just means the setup stage matters more than the packaging suggests.
The cameras that get hacked aren't usually the victims of sophisticated attacks. They're the ones still running default passwords, skipping firmware updates, and sitting on the same network as everything else in the house. A few minutes of configuration changes that matter significantly.

FAQs
Can smart doorbells be hacked?
Yes, smart doorbells can be hacked, particularly budget models with weak password policies, no encryption, and outdated firmware. A Consumer Reports investigation found that several doorbell cameras sold on Amazon could be accessed remotely by unauthorized users due to serious firmware flaws. Reputable brands like Ring and Google Nest are harder targets when two-factor authentication is enabled and firmware is kept current.
How do I know if my doorbell camera has been hacked?
Signs that your doorbell camera may have been accessed without your permission include unusual activity in the camera app's access log, the camera moving or changing angle on its own, unfamiliar devices listed under account sharing, and unexpected changes to your settings. If you notice any of these, change your password immediately, enable two-factor authentication, and check the app for recent login history.
What is the most important thing I can do to secure my smart doorbell?
Enabling two-factor authentication (2FA) is the single most effective step to secure a smart doorbell. Even if someone obtains your password through a data breach or credential stuffing, they can't access your camera feed without the second verification step. Changing your default password to something unique and never reusing it across other accounts is an equally essential baseline.
Are Ring and Nest cameras safe from hacking?
Ring and Google Nest cameras are significantly more secure than most budget alternatives, thanks to regular firmware updates, active security teams, and support for two-factor authentication. They are not immune to hacking, but the risk drops sharply when you use a strong unique password and enable 2FA. Reusing passwords from other accounts remains the most common way even reputable-brand cameras get compromised.
Can a hacked doorbell camera give attackers access to my home network?
Yes, in some cases a hacked doorbell camera can expose your home network. Research has shown that certain vulnerable doorbell cameras can capture Wi-Fi credentials, which attackers can then use to reach other devices on the same network, including laptops, phones, and smart locks. Connecting your cameras to a separate IoT or guest Wi-Fi network significantly limits this risk by isolating them from your main devices.
What should I look for when buying a smart doorbell to avoid security risks?
Choose a smart doorbell brand with an active firmware update history, published security policies, and support for two-factor authentication. Avoid budget devices sold under multiple brand names with no clear manufacturer, especially those controlled by a single shared app from an unknown company. Checking Consumer Reports' ratings before purchase is a practical way to filter out devices with known vulnerabilities.
