How to choose smart home and security devices
Pick the platform first: Alexa, Google Home, Apple Home or SmartThings. Use the one you already have on your phone and speakers, and check that each new device supports it. See Alexa vs. Google vs. Matter.
- Power: battery cameras and doorbells mount anywhere but need recharging; wired models need doorbell wiring or an outlet. Thermostats often need a C-wire.
- Subscriptions: video history and smart alerts often require a monthly plan. Check what works without one.
- Storage: cloud keeps clips if a camera is stolen; local microSD storage avoids fees.
