Yale IA-320 Sync Smart Home Alarm 6 Piece Kit review
Households wanting a self-monitored, no-subscription smart alarm that also covers a shed, garage or side access via its 200m wireless range.

A solid entry-level layer of security: wire-free to fit, no monthly fee, and loud enough to matter as a deterrent. It's self-monitored though, so treat it as an alert system for you, not a substitute for a professionally monitored alarm.

We may earn a commission when you buy, or a fee when you request a quote, through our links — it never affects what we recommend.

Prices and stock can change at any time, so always check the retailer's price before you buy.
- No subscription or monthly fee for core alerts (app, SMS, email) — but no cellular backup, so a broadband or power outage stops remote push alerts (sirens still sound locally)
- Works with Alexa and Google Assistant; expandable to ~40 devices for larger homes
- 200m wireless range covers outbuildings, not just the main house
- Base kit ships with only 2 PIR sensors and 1 door/window contact — most homes need extra sensors for full coverage
- Self-monitored only — no professional monitoring/response option, and no insurance discount should be expected
Who shouldn't buy this
Skip it if you want a professionally monitored system with 24/7 call-centre response or an insurer-recognised grade — this alerts you directly, it doesn't dispatch anyone.
