Smart Alarm Systems

Buy smart alarm systems

With smart alarm systems, you add an active security layer to your Smart Home: you detect events (such as a door opening or motion inside the house), you receive an instant alert, and you can manage the system easily. Unlike “just a camera,” an alarm system is designed to detect and deter—for example with a siren and clear warnings. This makes it a logical choice if you don’t just want to monitor your home, but also want visible, active protection.

This category is part of Smart Security and consists of products within the Smartlife Domotica ecosystem.

What’s included in a smart alarm system?

A good alarm system is built around a few core components that strengthen each other. You typically have a central control unit (often with a display), sensors that detect what’s happening, and a siren for an audible warning. In this category you’ll find alarm systems supplied with door/window contacts and PIR motion sensors, so you can secure both entry points (door/window) and routes inside the home (hallway/corridor).

Door contacts and PIR sensors: the foundation of reliable detection

The combination of door contacts and PIR is effective in real life because it covers two types of triggers: someone entering (door/window) and someone moving through the home (PIR). For extra coverage, you can extend PIR detection with additional PIR motion sensors in strategic areas such as a landing, back door, or garage (depending on your home layout and the zones you want to protect).

4G notifications and app control: extra certainty when WiFi isn’t enough

A key difference between alarm systems is how alerts are sent. In this range you’ll find systems with 4G notification and variants with 4G + app control. This matters if you want extra reliability—for example if you don’t want to depend solely on internet/WiFi for alerts and management.

You’ll also see sets positioned as wireless and “ready to use,” which makes it easier to get started quickly and expand later with additional components.

Choosing a siren: volume, connectivity, and power

The siren is your deterrent and your immediate warning signal. On this page you’ll find, for example, a 90 dB smart siren with Zigbee connectivity and power via USB-C or 2× CR123A. There’s also a wireless 85 dB siren with a strobe light, explicitly marked as compatible with only the brand’s own alarm system.

Practical tip: don’t choose sirens based on dB alone. Also consider placement (indoors/hallway), power (mains vs battery), and ecosystem compatibility. A siren that only works within one specific alarm system is best when you choose that system as your fixed base and plan to expand within it.

Build a complete security setup (without separate “islands”)

An alarm system works best when it’s part of a complete security approach. Many people combine an alarm kit with visual control around the home and extra visibility at the front door. This creates a logical security flow: detection (sensor) → warning (siren/alert) → verification (video). Combine smartly with:

• Smart cameras for live video and verification.
• Smart doorbells for door alerts and motion at the entrance.
• Smart Home to manage everything centrally and automate where possible.

Buying a smart alarm system: what to look for

Want the right match for your home from the start? Focus on (1) how alerts are delivered (e.g. 4G), (2) which sensors are included in the kit (door contacts and PIR), and (3) how your siren(s) connect (Zigbee or only within the system’s own ecosystem). This category offers a compact, focused assortment (4 products) to help you choose quickly: complete alarm kits with sensors and control, plus separate sirens to expand your setup.
