A security control room
in your pocket

Packed with Smart features, the Boundary app lets you customise and control your smart alarm system from anywhere.

  • Receive push notifications when your alarm is triggered, giving you a real-time notice of activity in your home that you can then monitor and control via the Boundary mobile app.

  • Create personal activity alerts and get notified of any activity or inactivity detected in your home while your alarm system is disarmed.

  • Your Boundary system will detect when you’ve left the house and not armed your alarm. You’ll receive a handy notification asking if you’d like to quickly arm the system from your phone.

  • Arm specific rooms or sensors instead of arming the entire alarm system, e.g. the entire ground floor at night.

Boundary can speak to your favourite smart assistant

Have fun creating arrival and exit automations for lights and speakers with the satisfaction of knowing it's all built on a seriously secure smart alarm system.

  • An alarm’s grade comes from the UK and European Standards on intruder alarms. It relates to alarm’s ability to recognise genuine break-ins and avoid false burglar alarms. Choosing a graded alarm will protect you against low quality or poorly performing products.

  • Burglar alarms don’t need a permit, which instantly makes them a simpler option to a CCTV system. Keeping a CCTV in line with local laws is a continuous task, they are not alarms, and therefore they can’t alert you should something go wrong at your home.

  • We are in the process of developing an advanced AI-powered camera that will detect suspicious activity and challenge it before a crime is even committed!
