Not always.
Smart bulbs, plugs, cameras, and video doorbells are often easy DIY installations, while full security systems may need professional setup.
Many devices still work manually or through local control.
You may lose remote app access, but locks, lights, and thermostats often continue basic functions.
Security depends on the device and setup.
Use strong passwords, trusted brands, firmware updates, and secure Wi-Fi for better protection. Privacy and unauthorized access are common concerns in smart homes.
