What It Is & How It Works

The Alarm Wireless Home Security System  is a complete, DIY smart alarm solution that protects your entire home – doors, windows, and rooms – against intruders. Control everything remotely via the Smart Life app: arm/disarm, check sensor status, or trigger the SOS button from anywhere.

Who is it for?

  • Homeowners & renters who want affordable, contract‑free security

  • Small business owners (shops, studios, offices)

  • Families needing an easy‑to‑use system with 24/7 optional monitoring

When to use it?

  • At night or when you’re at home → Home Mode (interior sensors inactive, perimeter active)

  • When you leave the house → Away Mode (all sensors armed)

  • In an emergency → SOS button sounds the siren and alerts you instantly

See It in Action (Images Explained)

Whole‑Home Security, Easy Install, No Contracts: The system is fully customizable and expandable – add as many sensors as you need.

Powerful Base Station: The 120dB siren scares off intruders. Works with Alexa & Google Home – say “Arm my system” or “Check home status” hands‑free.

Motion Sensor: Covers a full 120° area, perfect for living rooms or hallways. When triggered, you’ll get an instant push notification (as shown on the phone screen).

SOS Function: One‑tap emergency button on the keypad or in the app – ideal for medical emergencies or break‑ins while you’re home.

Three Modes Explained:

  • Home Mode – Occupants inside, only door/window sensors active.

  • Away Mode – No one home, all sensors armed.

  • Disarmed Mode – Everything off (only environment detection).

  • SOS – Instant help at your fingertips.

ey Advantages

✅ No long‑term contracts – pay month‑to‑month if you want pro monitoring, or use it as a standalone DIY alarm.

✅ 120dB siren – loud enough to scare intruders and alert neighbors (Image 5).

✅ Voice control – arm/disarm with Alexa or Google Home without touching your phone.

✅ SOS button – peace of mind for emergencies at home (elderly, children, medical needs).

✅ Expandable – start with the base kit and add sensors for every window, door, and room (Image 4).

✅ Remote access – check live status, get alerts, and control everything from the Smart Life app (Image 2).

✅ Easy DIY installation – no wiring, follow the user manual (Image 1).

Application Areas

  • Homes & apartments – full coverage for doors, windows, living rooms

  • Small offices – protect workstations and storage rooms

  • Garages & sheds – motion sensor triggers siren if someone enters after hours

  • Rental properties – give tenants a no‑contract security option

  • Parent & elderly care – use SOS button and app alerts for added safety

Frequently Asked Questions (FAQ)

1. Do I need a monthly subscription?
No. The system works fully as a standalone local alarm. You only pay if you choose optional 24/7 professional monitoring – and there’s no long‑term contract.

2. Can I use it without Wi‑Fi?
The base station and sensors work locally (siren, sensors). However, remote app control and push notifications require Wi‑Fi. The SOS button still triggers the siren even offline.

3. How many sensors can I add?
The system is expandable to dozens of sensors (door/window, motion, etc.). See Image 4 “Customizable & Expandable”.

4. What’s the difference between Home and Away mode?

  • Home Mode: Only perimeter sensors (doors/windows) are active – you can move freely inside without triggering the alarm.

  • Away Mode: Every sensor (including motion) is armed. Any movement triggers the siren.

5. How do I set it up?
Plug in the base station, download the Smart Life app, add devices by following the in‑app instructions, and stick sensors to doors/windows. The user manual (Image 1) shows step‑by‑step.

6. Does it work with Alexa and Google Home?
Yes. You can say “Alexa, arm my alarm” or “Hey Google, set the system to home mode” – demonstrated on Image 5.
