A security alarm system for your home is a worthy investment for every homeowner. There are two main reasons families choose to invest in an alarm system. The main reason is to protect your home from theft from an intruder. The second and far more important reason than the first, is to provide a safe environment for you and your loved ones. This is why so many new homes being built in Sydney, now come with a security system installed as part of their standard home inclusion. There’s been many studies made confirming that statistically, having an alarm installed, far reduces the likelihood of being burgled. Hence why so many opt to have alarm systems installed.

Types of Alarm Systems

Residential burglar alarms can be classified into four main categories, being Local alarms, back to base alarms (Monitored or Unmonitored), Hard-wired and Wireless alarms. These alarm systems can be installed in many different ways to suit your needs.

Monitored and Unmonitored Home Security Alarm Systems

Back in the late 1970’s, early 80’s only 10% of all security systems installed were monitored back to base, meaning that if the alarm system was un-monitored and a break in occurred, the alarm would trigger the sirens and you would have to rely heavily on your neighbours’ to investigate. Nowadays, due to technological advancement and increase in number of violent crimes in Sydney, over 90% of all security systems we now install are monitored back to base. A monitored alarm system will communicate alarm signals to the control room notifying them of exactly which alarm zone was triggered. Not only will the control room be notified as to which room has been breached, but the alarm will also send signals indicating power outages, low battery signals, panic or duress alarms. Your alarm can even inform the control room if the alarm is turned on or off.

‘Wired’ and ‘Wireless’ Alarm Systems

Your alarm system for your home can be installed as a wired or wireless alarm system.

Wired systems use security cables (extra low-voltage wiring) to connect the alarm components back to a control panel. For most homes, there is usually no difficulty running in the required security cables to get your alarm system fully installed.

Wireless alarm systems have evolved significantly in the past few years. Wireless alarms are mostly installed for premises where cabling can’t be run in due to cabling difficulties such as a unit or town house. Wireless alarms use wireless movement detectors and wireless door sensors (reed switches) that transmit alarm signals back to the alarm control box and will even transmit low battery signals to let you know when batteries need replacing. It’s our belief that a hard wired security system is still superior to a wireless security system since a hard wired system will always require less maintenance than a wireless one.

There are many different types of alarm systems available. Often, we install systems that allow both hard wired and wireless movement detectors and sensors to be used. This easily allows you to protect the garden shed out the back with ease.

Smoke detectors.

By incorporating smoke detectors into your alarm system you will have a much greater chance of protecting your property and loved ones from the unthinkable. Many insurance companies will now stipulate that if you wish to insure your home and contents for more than $1.5M, then a monitored alarm with smoke detectors will be needed to be installed in order to be insured.


Having a home security system installed is a cost effective method of improving security for your home and loved ones. Don’t wait till you get burgled.
