I installed my first smart doorbell because my building’s intercom broke and my landlord took three weeks to fix it. I chose a budget camera from a brand I had never heard of, set it up using the default password, and felt proud of myself for ten minutes. Then a friend who works in cybersecurity visited, laughed at my setup, and spent the next hour showing me everything I had done wrong. Here is what I learned — and what I changed that same weekend.
Your Wi-Fi Router Is the Front Door
Every smart device in your home connects through your router. If that is weak, everything downstream is vulnerable. I had never changed my router’s default admin password. I did not know what WPA3 encryption was. My network name was the default one that advertised my internet provider to anyone scanning nearby signals.
I fixed all three in under thirty minutes. I logged into my router settings, changed the admin password to a unique passphrase I do not use anywhere else, enabled WPA3 (or WPA2 if your router is older), and renamed my network to something generic. Then I created a separate guest network for visitors and for low-trust devices like cheap smart plugs and random gadgets I test for this site.
The guest network isolates those devices from my main network. If a $15 smart bulb gets compromised, it cannot access my laptop, my phone, or my security cameras. That separation costs nothing and adds a layer of protection I did not know I needed.
Smart Cameras: What I Check Before Buying
After my first cheap camera, I set minimum standards. Any camera I install must offer encrypted video, two-factor authentication on the app, and the ability to disable cloud storage if I prefer local recording. I also check whether the company has a history of data breaches or questionable privacy practices.
I point cameras at entry points — my front door, the hallway outside my apartment, and the window that faces the fire escape. I do not point them at spaces where I expect privacy, like my bedroom or bathroom. I also tell guests when cameras are present. It is basic courtesy and, in some places, legally required.
What I use now: A mid-range video doorbell with local storage and a single indoor camera for the main living area. I skipped the full multi-camera system because my apartment is small and two devices cover every angle that matters. For context on how I arrange my small space, see my guide to home lighting, where placement and visibility matter just as much.
Smart Locks: Convenience vs. Control
I considered a smart lock for six months before installing one. My hesitation was simple: I rent, and my lease prohibits changing the deadbolt. Instead, I found a retrofit option that attaches to the inside of my existing lock without replacing the exterior hardware. It took ten minutes to install and leaves no trace when I move out.
I create temporary access codes for dog walkers and visiting friends instead of sharing my main code. I delete those codes immediately after they are no longer needed. The app logs every entry, which means I know exactly when someone came and went. That history has been useful twice: once when a package was marked delivered but was not there (the camera confirmed the delivery time), and once when I could not remember if I locked the door before leaving for the weekend.
The Habits That Matter More Than the Devices
Devices help, but habits protect you. I update firmware monthly — I have a recurring phone reminder on the first Sunday of each month. I review app permissions quarterly and remove any device I no longer use. I keep a written list of all my smart devices, their brands, and which app controls them, in case I need to change passwords quickly or disconnect something.
I also maintain basic physical security. My smart lock supplements a standard deadbolt, not replaces it. My cameras supplement good lighting and visible door numbers, not replace them. Technology fails. Batteries die. Wi-Fi goes down. The goal is layered security, not total dependence on any single device.
What I Skip
I do not buy smart home devices that require subscriptions for basic features. If a camera stores video locally or on an SD card, that is sufficient for my needs. I do not need cloud backup for every motion alert.
I also skip devices from brands with no customer support contact or no public security policy. A cheap gadget is not a bargain if the company disappears next year and stops releasing security updates.
Smart home security is about managing risk, not eliminating it. Start with your router. Add devices one at a time. Verify each one before trusting it. And never let convenience outrank control.

Sofia Yaman has been figuring out how to make small spaces work since 2019 — first in a 280 sq ft studio in Brooklyn with a cat and too many books, now in a slightly larger rental where she still tests every storage hack and smart gadget before recommending it. She believes organized should never mean boring.
