Built for the Unexpected (mobile)

Built for the Unexpected

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

SmashSafe

An intruder can damage the keypad. Doesn't matter. We still alert the police. Sorry, bad guys.

Twice Secured

Built-in WiFi. Built-in cellular too. One connection down? The other’s still up. That means your home is always secure.

Built for the Unexpected

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

Disaster Ready

We have numerous monitoring centers spread across the country.

Power Outage Protection

The power fails. We don’t. In a blackout, a back-up battery kicks in and can protect you up to 24 hours.

Confirmed Alerts

Alert confirmation is big. It means that we send an alarm signal until the monitoring center confirms they got it. It’s how you can be absolutely sure help is there when you need it.

Deep Encryption

From sensor to Base Station to monitoring centers and back, your signals are encrypted.

Light's up keypad

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.

Detects Intruders, not pets.

Alarms that cry wolf? No thanks. We precision-engineered our motion sensors to detect the unique heat signature of humans. Not pets.

"This is one I'm hearing a lot about now. You don't have to drill anything. No wiring needed."
