Smart Home Without Dumb Risk

The smart home crept up on most of us. Nobody sat down and decided to install fourteen internet connected devices. You got a video doorbell because packages were disappearing. Then a speaker, because it plays music and sets timers. Then a plug for the Christmas lights that never came back down. Then a camera for the garage, a thermostat, a robot vacuum, and a lock so the dog walker could get in.

None of that is a mistake. These things are genuinely useful and we use them ourselves. But every one is a small computer sitting on your home network, made by a company you did not research, running software you cannot see. The good news is that the sensible version of a smart home is not complicated and does not require giving anything up. It is mostly five decisions, made once, that keep the convenience and remove the parts you would not have agreed to if anyone had asked.

Put the gadgets in their own lane

This is the single highest value thing on the list, and almost nobody does it. Your laptop, your phone, and your tax documents should not share a network with a twenty dollar plug from a brand you have never heard of. If the plug is ever compromised, it should find itself in an empty room, not in the same room as everything you own.

The Cybersecurity and Infrastructure Security Agency’s Project Upskill guidance on securing home Wi-Fi recommends exactly this, advising readers to “connect any smart home and other IOT devices to your Guest Wi-Fi if internet access is the only thing they require.” Most home routers made in the last several years can do this in a few taps.

Use the guest network your router already has. Look in the wireless section of your router’s app or admin page for a guest or secondary network option. Turn it on and give it its own password.
Give it a different password than your main network. CISA recommends making it long, random, and unique. Reusing your main Wi-Fi password defeats the purpose entirely.
Watch for the one exception. Some devices need to see your phone or a hub on the same network to set up. Those either belong on the main network or need a router that supports letting specific devices talk across the divide.
Do it once, at setup. Moving thirty devices later is a Saturday. Putting each new one in the right lane as you unbox it costs nothing.

The settings worth changing on day one

Every smart device ships in a configuration designed to make setup effortless, which is not the same as safe. There are usually only three or four things worth touching, and they take about two minutes per device.

Change anything the factory set. The Federal Trade Commission’s guidance on securing internet connected devices at home says to “Change the default administrative username, password, and network name to something unique.” Default credentials for popular devices are not secret, and they are the first thing anyone tries.
Protect the account, not just the device. A camera is only as secure as the app account that controls it. Turn on multi-factor authentication in the manufacturer’s app and use a password you have not used anywhere else. We wrote about the strongest version of this in our piece on what a security key actually is.
Turn off what you will not use. The FTC is direct here: “Disable features you won’t use. If you won’t use remote management, it’s best to disable it.” Remote access, cloud clip storage, microphones on devices you only want as cameras. Each one you switch off is one less thing to worry about.
Turn automatic updates on. Firmware is the software inside the device. If the manufacturer offers automatic updates, enable them, because manual firmware updates are a chore nobody actually performs twice.

Buy from companies that still ship updates

Here is the part of the smart home story that almost never comes up at the point of sale. Every one of these devices depends on the manufacturer continuing to publish security updates, and there is usually no way to find out how long that will last.

The Federal Trade Commission published a staff report on November 26, 2024 that surveyed 184 smart products and found that 161 of them, nearly 89 percent, did not disclose on their websites how long they would receive software updates. Samuel Levine, then Director of the FTC’s Bureau of Consumer Protection, said in the accompanying announcement that “Consumers stand to lose a lot of money if their smart products stop delivering the features they want.”

You cannot solve that as a shopper, but you can shop smarter. Before buying, spend two minutes searching for the brand’s support page and see whether they publish an end of support date at all. Companies that state one tend to honor it. Companies that say nothing are telling you something.

Cameras, placement, and the people who live there

Cameras are where smart home technology stops being a technical topic and becomes a household one. The right question is not whether a camera is secure. It is who is in frame, who can watch, and whether everyone in the house knows.

Point them at entrances, not at living. Doors, driveways, the side gate, the garage. Not the living room where your family actually relaxes, and not bedrooms or bathrooms, ever.
Mind what the doorbell catches. A doorbell camera often sees a good deal of the sidewalk and a neighbor’s front yard. Most models let you mask out zones. It is a neighborly thing to do.
Tell the household. Kids, roommates, guests staying the week, cleaners. A camera nobody was told about is the thing that damages trust, not the camera itself.
Check who has access. Shared accounts accumulate people. An ex-partner, a former roommate, a contractor you gave temporary access to two summers ago. Review the list of users in the app and remove anyone who no longer belongs.
Look at the logs. The FTC recommends that you “check the camera’s access logs regularly for unauthorized access,” watching for addresses you do not recognize or sign ins at odd hours.

Know what you have, and retire what you do not

Ask most people how many connected devices are in their house and the guess is off by half. That matters, because you cannot secure or update a thing you have forgotten about. Open your router’s app and look at the list of connected devices. It usually takes five minutes and it is almost always educational.

Then deal with the leftovers. Old devices do not stop being on the network just because you stopped using them, and abandoned gadgets are the ones running the oldest software. The FTC advises that you “disconnect older devices you no longer use from the network. Their security may be out of date, creating a weak point.” The tablet in the drawer, the smart speaker in the garage, the camera you replaced but never unplugged: unplug them, factory reset them before you sell or donate them, and remove them from the app.

The bottom line

A smart home is a good thing. It just deserves ten minutes of thought at setup rather than none. Put the gadgets on a separate network from your computers and phones. Change the factory passwords and protect the app accounts. Buy from companies that will still be pushing updates in a few years. Point cameras at doors, tell the people you live with, and check who has access. Once a year, look at the device list and unplug what you no longer use.

That is the entire list, and it holds up regardless of which brand you bought. If you get stuck on the guest network step, or you look at your device list and see something you cannot identify, we are happy to talk it through with you. Contact us today.
