Why Buy?
Peace of Mind, Without the Hassle of Wiring
If you want a louder, smarter layer of protection for your home without calling in an electrician, this outdoor siren delivers exactly that — simple to set up, serious when it counts.
When something triggers your Eufy security system, this siren kicks off a 105-decibel alarm that's hard to ignore — loud enough to alert neighbours and deter anyone who shouldn't be there. At the same time, you'll get an instant notification on your phone, so you're always in the loop no matter where you are. It connects reliably to your existing Eufy HomeBase, meaning it works seamlessly as part of your wider security setup rather than as a standalone add-on.
Because it runs on battery, there's no messy wiring involved — just mount it outside and you're done. The two-year battery life means you're not constantly swapping batteries or second-guessing whether it's still working. It all ties back into the Eufy Security app, giving you one place to manage your home's protection without juggling multiple systems.
Buy This If…
- You want a visible, audible deterrent outside your home
- You already use Eufy security products and want to expand your setup
- You'd rather avoid wiring or professional installation
- You want instant phone alerts when an alarm sounds
- You need a low-maintenance outdoor security solution
