How much does a home security system cost?

Having a home security system is integral in protecting your family and belongings, but they’re not cheap. Costs generally range from $300 to $4000 depending on the size of your home, and the complexity of the system. On average, installing a hardwired system in a 130 square-metre home costs between $1,800 and $2,900.

Components & cost of a home security system

Home security systems are typically made of some or all of the following components:

Control panel activation and installation

Control panels allow you to access, connect, and control elements of your home security system, like enabling and disabling sensors and alarms. Activation and installation typically range from $700 to $1,900, while monitoring averages $15 to $60 on a monthly plan. Companies may include a fee with installation, or an ongoing maintenance plan.

Home security cameras & surveillance

Home security or CCTV cameras offer visuals of your home, which can be installed outdoors and indoors to give a comprehensive idea of all that happens inside and outside your home. Traditional security cameras record footage when motion is detected, while newer and more expensive wireless cameras can be viewed and controlled via your smartphone.

Expensive and wireless CCTV cameras will often cost more in installation. A low-end camera (without installation costs) averages around $250, and an additional $30 per month in surveillance costs. In comparison, a high-end CCTV camera can cost upwards of $1,200, without installation or monthly surveillance costs.

Door and window sensors

Motion sensors can utilise infrared, heat, or ultrasonic technology to detect movement within or outside your home. Sensors can cost between $15 to $60 each, depending on if they are hardwired or wireless. While hardwired sensors can be cost-effective, they’re much more time consuming and labour-intensive to install. In comparison, wireless sensors are easy to install and upgrade but can prove expensive if the software is new.


Fire, smoke, and burglar alarm costs vary depending on the type and quantity of the alarm. Generally, alarms range from $30 to $50 per alarm, not including installation costs.

Security screens

To be sold, these physical barriers must conform to Australian safety standards. These include AS 5049 for security, AS 5040 for installation, and AS 5041 for testing. Guaranteeing they withstand various tests in impact, leverage, and cutting ensures their durability and ability to withstand force from an intruder. Costs range from $600 to $1,400, with installation varying depending on the door size, type, and material.

Getting an accurate estimate for your home security system

Do you know the size of your home and the areas you want to be covered? How many doors and windows do you want to be secured? The price often increases with a greater surface area and more units that need installing.

Additionally, check your home insurance policy as you may be able to get discounts on installation.
