DIY alarm FAQs

It may feel like it goes without saying, however, you need to pick the right system for your property. Many DIY security systems offer something for every home. Key things to consider before opting for DIY alarm installation include:

  • The number of doors and entrances you have
  • How comfortable you are at with DIY. Can you drill holes and comfortably install sensors and sirens?
  • Do you want Level 1 police response monitoring? This is only available with professional installation.
  • Do you have the right equipment? You’ll need stepladders to start.
  • How good is your WiFi?
  • Do you have other smart home devices for it to integrate with?

Boundary has a system for designing your own alarm system, to help you work out whether you’re ready to install a system yourself.

Yes, of course. Boundary’s DIY security systems are simple and easy to install. All you need to do is think about where you need each motion detector to go. However, if you choose our police response services, you’ll need our pro installation.

You upgrade to a police response security system, but that does require pro installation to ensure proper implementation. Boundary’s monitored alarms give you ultimate protection against break-ins. If your alarm is triggered, the hub will notify the ARC immediately. ARC then assesses the situation and will call the police if necessary. Your keyholders will also be informed.

It depends on the size of your house and which rooms you want to monitor. Our pre-built bundles come with entry sensors and PIR motion sensors. Personalise your DIY systems by adding more sensors, key fobs or an outdoor siren.

Use our calculator to design your own alarm system.

There’s no need to worry about false alarms. Calibrate Boundary’s PIR motion sensors to ignore pets under 35kg. If this doesn’t work for you, create a pet-friendly zone in your house. Doing this won’t hinder your other motion detection sensors.

Our DIY home security systems use world-class wireless technology Z-Wave® to communicate. All data is encrypted, protecting communication between your hub, sensors and siren.

Wifi is only used to report to the Alarm Receiving Centre (ARC). If your internet connection drops, our hubs feature optional cellular backup for just £5 per month. Your smart hub will automatically switch to cellular data when required.

Yes, it will. Boundary hubs have a 12-hour backup battery and will remain operational if the power supply is interrupted. Don’t worry if an intruder cuts your phone lines. Your hub will use a mobile signal instead to communicate with the ARC if you’ve chosen the cellular backup option.

Personalise your smart security system with other smart home gadgets. Boundary systems work with:

  • Amazon Alexa
  • Google Home Assistant 
  • IFTTT (including Philips Hue)
  • Samsung SmartThings 

Apple HomeKit integration is also planned for late 2021/early 2022.
