How to Build a Home Security System Without a Monthly Subscription
Wired has compiled a list of smart home security devices that let users build a full security setup without recurring subscription fees, relying on local storage instead of the cloud. The trade-off is losing access to professional monitoring services.
Most smart home security systems from brands like Abode, SimpliSafe, ADT, and Vivint rely on subscription models — without a monthly fee, users typically lose access to reviewing video history, certain notification types, and professional monitoring, where a staff member can call police or fire services on your behalf. That live monitoring service is the one thing that can't be replicated with a DIY setup.
However, many devices now offer local storage instead of cloud storage, allowing users to skip subscription fees entirely. Among smart locks, the Aqara Smart Lock U50 stands out for working via Bluetooth, with optional Wi-Fi control through a separate hub, while the Level Lock Pro offers a discreet design but requires purchasing a separate Wi-Fi bridge and keypad.
For video doorbells, the Eufy Video Doorbell E340 includes 8GB of built-in storage expandable to 128GB via microSD, while the Reolink Video Doorbell requires a wired connection but offers person detection without a subscription. For outdoor cameras, the Eufy EufyCam S4 includes 32GB of built-in storage, while TP-Link's cheaper Tapo line supports microSD expansion up to 512GB for both indoor and outdoor use.
For motion sensors, the Letwesaf Radar Motion Alarm System suits large properties with a range of up to half a mile and needs no Wi-Fi or app, while the Kinisium Kini SafeAlert Wi-Fi Motion Sensor is designed to protect cabinets and valuables. Combining such devices lets users tailor a system to their own needs while paying only once for the hardware itself.
