Smart home devices make life easier. You can turn off lights with your voice, check who’s at the door from your phone, or adjust the thermostat without getting up. But there’s a catch. Many of these devices collect data about you and your family. Sometimes, they even listen or watch when you don’t expect it. If you care about privacy, you need to know which smart home devices could be spying on your family.
Here are nine common smart home devices that might be collecting more information than you realize—and what you can do about it.
1. Smart Speakers
Smart speakers like Amazon Echo and Google Nest are always listening for their wake word. But they don’t just listen when you say “Alexa” or “Hey Google.” Sometimes, they record by mistake. These recordings can be stored on company servers. Employees or contractors may review them to improve the service. If you want to limit this, check your device settings. You can delete voice recordings and turn off “improve voice recognition” features.
2. Smart TVs
Smart TVs do more than stream your favorite shows. Many models track what you watch, when you watch it, and even what you say if they have voice controls. Some TVs use Automatic Content Recognition (ACR) to scan what’s on your screen and send that data to advertisers. If your TV has a camera or microphone, it could be recording you. Go into your TV’s privacy settings. Turn off ACR and voice recognition if you don’t use them. Cover the camera when you’re not using it.
3. Video Doorbells
Video doorbells like Ring and Nest Hello record video and audio outside your home. They can also pick up conversations on the sidewalk or street. Some models store footage in the cloud, where it could be accessed by company staff or even law enforcement. If you want more control, use local storage if possible. Adjust the motion detection range so it doesn’t record the whole neighborhood. Check your sharing settings to see who can access your videos.
4. Security Cameras
Indoor and outdoor security cameras help you feel safe. But they can also be a privacy risk. Some cameras upload footage to the cloud by default. Hackers have accessed live feeds in the past. Even if you trust the company, employees might review footage for “quality control.” Use strong passwords and enable two-factor authentication. If your camera supports local storage, use it. Turn off cameras when you’re home if you don’t need them running.
5. Smart Baby Monitors
Modern baby monitors connect to Wi-Fi and let you check on your child from anywhere. But this convenience comes with risks. Hackers have broken into baby monitors and spoken to children or spied on families. Some monitors record audio and video, storing it online. Always change the default password. Update the firmware regularly. If possible, use a monitor that doesn’t connect to the internet.
6. Smart Thermostats
Smart thermostats like Nest and Ecobee learn your habits. They track when you’re home, when you leave, and what temperature you like. This data can reveal your daily routine. Some companies use this information for marketing or share it with third parties. Check your privacy settings. Limit data sharing and disable unused features. If you’re concerned, consider a programmable thermostat that doesn’t connect to the internet.
7. Smart Plugs and Lights
Smart plugs and lights seem harmless. But they track when you turn devices on and off. Over time, this data can show when you’re home or away. Some brands collect this information and use it for targeted ads. Review the privacy policy before buying. Use devices that work locally, not just through the cloud. Turn off remote access if you don’t need it.
8. Smart Appliances
Refrigerators, ovens, and washing machines are getting smarter. Many now connect to Wi-Fi and collect data about how you use them. Some even have microphones or cameras for voice controls or internal monitoring. This data can be shared with manufacturers or third parties. Check what data your appliance collects. Disable features you don’t use. If you don’t need your fridge connected to the internet, don’t connect it.
9. Smart Home Hubs
Smart home hubs connect all your devices. They can see everything that happens in your home network. If the hub is compromised, hackers could control your devices or access your data. Always update your hub’s firmware. Use a strong, unique password. Limit the number of devices connected to your hub.
Protecting Your Family’s Privacy Starts at Home
Smart home devices offer real benefits, but they also come with risks. Every device you connect is another way your family’s privacy could be exposed. Take time to review the privacy settings on each device. Turn off features you don’t use. Use strong passwords and keep your devices updated. If a device doesn’t need to be online, disconnect it. Your home should be a safe place, both physically and digitally.
