How to choose the perfect alarm system for your home or business

Alarm Systems

Customisation, supply and Installation

Since the beginning of time, there has always been a need to protect your loved ones and belongings from outside threat. In our modern world, this is more important than ever. We now have laptops, phones, jewellery and other important belongings, often with significant price tags, irreplaceable data and/or high sentimental value.

Few of us work at home and most of us are absent for long and predictable periods. Our homes are left unattended and unprotected. By using modern communication technology like a wireless alarm system, you can be alerted almost instantly of a perimeter breach, allowing you or a monitored service to take swift and decisive action. Your home or business is worth protecting, and you can do this in a simple and cost-effective way by installing a security alarm.

Whether it’s a residential or a commercial alarm needed, Symetrix is here to assist you in finding the right monitored alarm system for you. We have a selection of alarm packages available and are here to assist with alarm installation Sydney wide as well as the Central Coast, NSW.

The components of your alarm system

A correctly operating alarm monitoring service and system fosters trust. When an alarm is triggered, you know an actual breach has very-likely occurred. And so do your neighbours!


Reed switches

Reed switches are a two(2) part device that is secured to your door or window. They are triggered when the window or door is opened by as little as 2cm, making it likely that the offender will abort the break in immediately.


Emergency help monitoring

Your system can be designed to include emergency help points, information lines and after hours access points. These emergency help points can be configured to call dedicated operators, or after hours contacts depending on your particular needs.


Sirens and strobes

External sirens are 120db, low pitch and designed to alert neighbours and passers by. Internal sirens however are higher pitched, making it uncomfortable for anyone to remain in your home or in the immediate vicinity.


Motion sensors

A simpler home alarm system may use motion sensors to detect moving bodies of heat within a room.


Core alarm system

The brains of the system are housed in the main-board (or panel). A back-up battery kicks in if power is cut and typically lasts up to 24 hours.



We offer a 5 inch colour touch screen as standard. These attractive keypads are stylish and easy to use, and give the user smartphone like power over their alarm system.

Customised alarm systems

Alarm systems can be as simple, or as elaborate as you want.

A simple solution could include:
  • A panel and keypad,
  • Motion sensors,
  • Siren, and
  • A strobe alert-light on your building’s front.
A more comprehensive approach might include:
  • Reed switches on your doors and windows,
  • The ability to arm selected sections of your home, even when you or your loved ones are in the home,
  • Remote arming and disarming via your smartphone, and
  • Critical-Incident-Connectivity: if your alarm is tripped, our server automatically responds as pre-arranged with you, providing push notifications, SMS alerts, emails and/or phone calls.

Alarm installation

Our consultants in Sydney will help you design a best-fit system for your unique needs because effective and efficient system design is critical to ensuring your system actually does what you want it to do.

A customised alarm solution for the security  of your business.

If you own a business, one of the best ways to protect it is with business alarms. We take into account your individual priorities when designing a tailored alarm system for your business.

If you feel that you and your family would prefer to stay within an armed detection area, for example, while you are all asleep, then door and window contacts would suit your needs.

If however, your key concern is what happens when you are away from home, then motion detectors alone may suit your needs. You might want to consider a back to base alarm or wireless alarm to protect your property.

Our consultants will design a specific solution to meet your needs and address your particular concerns.
