Deter intruders before they get in – not after.
Your First Line of Defence
Starts at the Front Door.
An alarm that goes off at the right moment – and an intercom that lets you verify who’s there before you open the door – are two of the most effective deterrents available for any property. Mac-Tek Telecom designs and installs tailored alarm and intercom systems for homes and businesses across Sydney. Whether you need a basic monitored alarm for a residential property or a fully integrated intercom system for a multi-entry commercial building, we’ll recommend the right solution for your specific situation.
We install alarm and intercom systems across Western Sydney, including Penrith, Blacktown, Parramatta, Mount Druitt and St Marys, and in Nightcliff, NT. Every job starts with a free site assessment and is backed by a 12-month workmanship warranty.

Frequently Asked Questions
Should I choose a monitored or unmonitored alarm?
A monitored alarm alerts a control room that can dispatch a response. An unmonitored alarm notifies you directly and sounds a siren. We install both and will explain which suits your property and budget.
Can I answer my intercom from my phone?
Many of the video intercoms we install can be answered from a smartphone app as well as an indoor monitor. We will recommend a model that suits the way you use the property.
Do you install panic or duress buttons?
Yes. Fixed and wireless duress buttons are a common addition for retail counters, medical practices and sites with after-hours staff.
Can the alarm work with my cameras and access control?
Yes. Alarm, intercom, CCTV and access control can be integrated so an alarm event triggers camera recording and door lockdowns.
How long does installation take?
A typical office or home intercom and alarm installation is completed in a single day with minimal disruption. Larger sites are staged after a site assessment.
