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. We do this by taking tried and tested security tech and introducing 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:

Designed to meet UK and European Standards

You may have noticed that almost all intruder alarms use door and window contact sensors and motion sensors to protect your home. You’ve probably also noticed that we’re all priced differently. This is partly down to the quality of components.

We’re building our alarm to meet UK and European standards (EN50131) in alarm reliability and robustness. Meeting these standards 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.

Passing all these tests will help minimise false burglar alarms, this is important to stop you you losing confidence in the alarm system

Also worth noting, these standards are recognised by insurers, alarm companies and the police. Read more about graded vs ungraded alarms

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 PIR sensor will ignore pets below 35kg. 


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. You can then quickly 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. See our IFTTT Applets here.

Integration with Alexa, Google Home and more!

Boundary directly integrates with Nest Home Hub (formerly Google Home Hub) and Amazon Alexa.

*Not compatible with police response, on the Complete plan

We plan to integrate with SmartThings and Apple Homekit, but this will come later in 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*.

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 Alarm 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.

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

According to Which? bugs account for around 30% of false alarms in the UK. 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 automated phone call. You can also nominate keyholders, who will get a call notifications if you can’t respond.

Professional monitoring and police response (Coming late 2021)

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 monitoring and a police response when a break-in has been confirmed

UK-based customer support

As a customer of Boundary, you get an ongoing service from the day you become a customer.

We have UK-based customer service team who are always on-hand to solve any technical problems. They can be reached via chat, email or social media.

Similarly, our team of developers provide the ‘invisible’ service you receive. After you become a customer, you’ll benefit from new features, more smart home integrations and UX improvements. 

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.

We take a different approach. Our monthly plans are totally transparent and available on our website. We 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 are some of the most affordable in the UK, particularly if you want 24/7 monitoring. If you want monitoring with a police response, you’ll be hard pressed to find a monthly plan costing less than our Pro plan!
