Police Response Alarms

Limit false alarms from your four-legged friends

Don’t worry about your favorite pet tripping your alarm. Boundary’s sensors accurately ignore your pet based on their weight. If this isn’t right for you, simply set up a special zone for them to chill-out, without hindering your other sensors. Leave your favorite furball at home with complete peace of mind.

Pet-friendly alarm systems

The home security system that talks to your phone

Get the Boundary home security app on your smartphone and never miss an alert on the go. The Boundary app lets you alert the last person out, spot when batteries are running low, and, most importantly, alerts you to intruders. Have full control of your home security wherever you are.

Smartphone controlled alarm systems

Intelligent Security for your smart, or not so smart, home

Connect your Boundary security system to your other smart home devices and add your own customised security features. Want the lights to turn on when you get home? You can do that. Want a dog to bark when your sensors pick up a possible intruder? You can do that too. Our home security systems are completely wireless, using Z-Wave® technology, and don’t need a smart home hub to run.

The tech that makes up your new home security system

Your Boundary home security system is made up of a hub, sensors, fobs, sirens and intelligent software.

The Hub Control Panel

Tying together your home security system. The hub sits at the heart of all your devices.

Home Security Hub

Motion Sensors

Never miss a motion. Our sensors communicate instantly with your hub and the app.

PIR Sensors

Door & Window

Simple, tamper proof and do exactly what you expect. Keep your boundary safe. Any breaches and you’ll know.

Contact Sensor

Key Fob

Arm and disarm your home alarm systems with your own key fob.

Alarm Fobs

Outdoor Siren

We keep it simple where it matters. Our outdoor siren acts as a deterrent for intruders. Our burglar alarms have a 95 decibel siren when you need it.

Siren Alarms

If This Then That

Tailor your security for your own needs. If a siren isn’t for you, then you choose what happens instead. Play a dog barking or turn on the lights. Sync your alarm system with your smart home for custom features.
