What makes the Boundary Alarm different?

Intruder alarms have been around for decades, so you might be wondering what makes Boundary different.

Our aim is to take proven alarm technology and modernise it. With the Boundary alarm, you get tried and tested burglar detection methods combined with Internet of Things (IoT) capabilities.

With four monthly plans, you can choose the features to suit your needs, all the way up to professional monitoring with a police response. In fact, we’ll be the first smart alarm in the UK to offer this.

Here is a breakdown of some of the most exciting things the Boundary alarm will offer:


Conforms to UK and European Standards

You may have noticed that almost all intruder alarms use contact sensors and motion sensors to protect your home. You’ve probably also noticed that we’re all priced differently. One of the main reasons for this is the quality of the components.

We’re building our alarm to meet UK and European standards (EN50131) in alarm reliability and robustness. Passing these tests is a big deal, and requires a lot of investment.

For example, our motion sensors will be independently tested against dry heat, extreme cold, power cuts, mechanical shock, vibration and impact attacks. All types of human movement will be checked: slow to fast moving, intermittent, close-up. We’ve added anti-tampering technology too, so intruders can’t defeat our alarm by removing or destroying the Hub.

These standards are recognised by insurers, alarm companies and the police. In fact, an alarm company can’t offer a police response without your alarm conforming to them. Read more about graded vs ungraded alarms

Professional monitoring and police response

An alarm that conforms to UK and European standards offers the possibility of a police response. The alarm must be professionally installed, but it’s worth it. If you have a lot of valuables or you’re away from home a lot, a police response gives complete peace of mind. Boundary’s Complete plan comes with 24/7 and a police response when a break-in has been confirmed. Read more about the police response here.

Pet-friendly PIR Motion Sensors

To a PIR sensor living things are simply moving blocks of infra-red heat. Generally, sensors will not discriminate between the size and location of the movement, meaning it’ll react to both humans and pets.

Fortunately, techniques have been developed to avoid this. To recognise and discount pets a PIR sensor can be programmed to ignore movement based on weight – the Boundary sensor will ignore pets below 35kg. Read more about Boundary PIR sensors here.


To understand geofencing, imagine an invisible fence around the perimeter of your home as a 360 circle. Should you leave the fenced area without setting your alarm you’ll get reminded to set it.

From research, we know that many don’t set their alarm because they forget or they only remember when they’re halfway to work. With Geofencing and the Boundary alarm, you’ll receive a push notification, select it to open the phone app and set your alarm. Easy! 

Geofencing can detect you coming home too, so we’re looking at future ways to use this.

Home Automation

With home automation you can use Boundary’s sensors to turn on / off smart appliances and make your life easier and safer.

When you’re out at night or on holiday, the Boundary alarm can simulate you being home by randomly turning Philips Hue lights on and off in different rooms.

When you arrive home, Boundary motion sensors can detect you entering and turn on smart lights to welcome you. It can also detect you moving from room-to-room and turn on smart lights.

IFTTT (If this, then that)

IFTTT is a free way to get all your apps and devices talking to each other. Not every smart home device plays nice, so IFTTT acts as a middle-man.

For example, you’ll be able to IFTTT between Boundary and Philips Hue, so that if Boundary alarm detects an intruder the lights will start flashing.

You can use existing commands, made by other users, create your own or request that we build one. Read more about IFTTT here.

Integration with Alexa, Google Home, Smart Things and more!

Boundary will be directly integrated with Nest Home Hub (formerly Google Home Hub) and Amazon Alexa. We also plan to extend this to Apple Homekit in the first half of 2021.

To use Voice command assistants you give a command like “Alexa … disarm boundary with code” then say your passcode – a different passcode you’d input using the Central Hub’s keypad*.

*Not compatible with police response, on the Complete plan

Cellular backup

Cellular backup means your alarm can still message you and request a police response* even if the Wi-Fi stops working. Instead of the internet, the Central Hub uses 4G to send a message to you or the alarm monitoring centre (depending on your monthly plan). This means that your home is still protected if the burglar cuts your telephone cable.

As Cellular Backup requires a SIM card, with a phone contract, Boundary charges a small monthly fee for the service. The Hub will also need to be upgraded.

*subscription required

12-hour backup battery in Central Hub

The Central Hub will be mains powered with a battery backup. This conforms to Grade 2 requirements and means the Boundary alarm will continue working even in the event of a power-cut.

Minimum 12-month battery life in sensors

While Boundary’s sensors will have 12 months of battery life guaranteed, we expect this to be closer to 36 months of real world use. A lot of this depends how you use them, for instance in a busy shop, you might want to consider disabling the LED on the door contact to save battery life.


The Central Hub and sensors will have all sorts of tamper-proofing technology. If the Central Hub or sensors are disturbed in any way while the alarm is active, you’ll be notified.

Some attacks are designed to exploit alarms without tamper-proofing, like the crash and smash. This is where the burglar breaks into the home via the front door and destroys the Central Hub before it can activate the alarm. The burglar exploits the 30-second countdown that the owner gets to disarm the alarm.

To be effective, a combination of tamper-proofing and cellular backup is recommended, as the burglar could disconnect the internet before destroying the Central Hub.

Boundary Phone App

Zone setting

Where a specific section of the home is armed e.g. all downstairs sensors or all window sensors. Useful in case you’re the only one at home or if your dog is heavier than 35kg.

Nightly reminders

The Boundary alarm will remind you to set the alarm when you’re going to bed. Useful considering around half of burglaries occur when the owner is at home!

Z-Wave 700

To provide the strongest signal, and allow the Central Hub reach every corner of the home, we’re using Z-Wave 700. Released in December 2018 this version of Z-Wave offers improved energy efficiency, better reliability and 250%  longer range capabilities.

Sealed optics

A PIR sensor with sealed optics works effectively to protect against insects crawling into the sensor and setting off false alarms.

Choice of notifications

With the Boundary alarm you’ll be able to choose how you get notified. You can choose from push notifications or phone calls. You can also nominate keyholders, who will get these notifications.

Transparent and affordable pricing

For many alarm companies you often have to request a quote before you see any pricing. The sales-person may use tactics like discounts or extras to persuade you to buy, often starting from a high price point to make it seem like you’re getting a good deal.

Boundary is taking a different approach. We’ll be making our pricing totally transparent and available on our website. We’ll offer a range of affordable subscriptions for all sorts of homes, so that you can choose a plan to suit your needs.

Our monthly plans will be some of the most affordable in the UK, particularly if you want monitoring. If you want monitoring with a police response, you’ll be hard pressed to find a monthly plan costing less than our Complete plan!
