Residential Alarm Systems

Home alarm systems from Castle Security provide peace of mind and protection for your home, family and valuables.

As Australia’s security alarm experts, we can help you protect the things that matter most with an affordable and reliable home alarm system designed just for you.

Why you need a home alarm system

Home alarm systems do more than alert the owners to a break-in.

  • Protect valuable and priceless items
  • Lower insurance premiums
  • Remote CCTV viewing
  • Intruder deterrence
  • 24/7 monitoring
  • Wireless alarm system integrated to access control device
  • Medical security for elderly and disabled people

Break-ins, fires, theft, property damage: these are all things we hope to never experience at home. And yet, unfortunately, tens of thousands of Australians every year are left to deal with these unthinkable situations. Avoid becoming a cautionary tale by installing a full home alarm system.

What to consider when choosing a home alarm system

There is no one-size-fits-all security system for Australian homes. That’s why every home alarm system designed by our team is driven by two questions:

  1. What, where and who needs to be protected?
  2. Where are the points most vulnerable to intrusion?

Not sure where to start with your home security system? Here are a few questions, tips and pointers to get started:

  • Can you afford the risk of not installing a home alarm system?
  • Do you want internal security, or full perimeter security?
  • Do you want your home security system to integrate with smart home devices?
  • Will you require security alarm monitoring if you travel or after a medical procedure?
  • Consider your home’s entry points, dark places nearby, and location of valuable items.
  • Our systems let you monitor alarm status and check in to CCTV at any time.
