Keep your home safe without the false alarms from your four-legged friends

Discover the home security system that lets your cats and dogs rest easy without a false alarm. Manage your sensors in the Boundary App for additional peace of mind.

How do our pet-friendly alarm systems work?

Our alarm systems are designed with your pets in mind. We use pet-friendly PIR sensors that can be calibrated to ignore your pets. Before you worry this could open up your house to intruders, let us explain how our PIR detectors differentiate between a would-be burglar and your furry friends:

Enable pet sensitivity and your PIR sensor to disregard weights under 35kg (the weight of an average labrador).

That’s it, it’s really that simple.

Create a pet tolerant zone for your cat or dog

If this isn’t the solution for you though, If you have a larger pet or multiple pets, why not create a pet-friendly area using Partial Set. Simply select the sensors you want to activate when you Partial Set, leaving out any areas where your pets can play safe from the sensors. 

Isolating zones like this is incredibly simple with the Boundary Hub control panel or the Boundary app.

You can set your burglar alarm’s PIR motion sensors to ignore anything under 35kg, which rules out most dogs and all cats.

For dogs that weigh more than 35kg you can set up a pet-friendly zone. To do this you just need to nominate spaces to remain deactivated that your big dogs can play to their heart’s content in.

How to partially set your alarm

There’s no guarantee that you’ll stop getting false alarms, but with your sensors calibrated effectively you should be able to rule out pet movement. If your alarm is triggered, you’ll get an alert immediately and you’ll be able to see which sensors have been triggered and whether it’s likely to be your pet.
