    If someone tries to break in, your
    Base Station alerts our monitoring
    centre, then sounds a loud 95dB siren.


    It doesn’t need to be plugged in, so
    you can place it anywhere you like.
    We recommend by the front door.


    We use the entry sensors to guard the
    front and back door, plus two large and
    easily accessed ground floor windows.


    SimpliCam is calibrated to detect the unique
    heat signature of humans. That, along with
    night vision and a 120° field of view, means
    even the stealthiest thief doesn’t stand a chance.

Anyone can set up SimpliSafe in just a
few minutes. No drilling. No tools. Just
plug in the Base Station, place your
sensors, and start protecting your home.

Real home security prepares for
the worst. So we built backups.
And backups for those backups.

Lights up when the sun's down

The all new touch-to-wake keypad. Lights up when you need to see it. Goes dark when you don't. It doesn't need power, just a good place to put it.

Less markup.
More security.

A common misconception: the more you pay,
the more you get. But the truth is you’re
paying for more markup. Not more security.

You shouldn't have to pay more so we can do less.
We cut out the middlemen, so you get award-winning
protection at fair and honest prices.
