Intercom Systems Perth: Complete Buyer's Guide

An intercom system does one thing that no other security device does: it lets you see and speak with whoever is at your door before you decide to let them in. For Perth homes, strata buildings, and commercial properties, the right intercom system gives you control over who enters without compromising convenience. This guide covers everything you need to choose the right system — including how wiring affects your options, which brands are worth specifying, and how intercoms work alongside CCTV and access control.

What Is an Intercom System?

An intercom system connects an outdoor entry station — typically mounted at a front door, gate, or building entry — with an indoor monitor or handset inside the property. When a visitor presses the call button, the indoor unit rings and the occupant can speak with them, see them (on a video intercom), and remotely release a door lock if required.

Modern intercom systems for Perth homes and businesses have evolved significantly from the old analogue buzzers. Today's IP video intercom systems offer HD cameras, two-way video, smartphone apps, and direct integration with electric locks and access control platforms. The older analogue systems are gradually being replaced as Perth property owners upgrade.

Types of Intercom Systems: 2-Wire, 4-Wire, and IP

The most important decision when choosing an intercom isn't the brand — it's the wiring technology. Your existing infrastructure often determines which systems are practical without a full rewire.

2-Wire Intercom Systems

2-wire intercoms carry audio, video (on compatible systems), and power over a single pair of wires. They're popular in Perth residential properties because they're compatible with much of the older cabling that already exists in homes — if you're upgrading an ageing audio-only intercom, there's a good chance 2-wire video intercom hardware will work on your existing cable run without any additional wiring.

Best for: Residential upgrades where 2-wire cabling is already in place. Also common in strata and apartment buildings.

4-Wire Intercom Systems

4-wire systems use separate wire pairs for audio, video, and power. They were the standard for video intercoms before IP became prevalent, and many Perth properties installed in the 2000s–2010s have 4-wire infrastructure. Most modern video intercom hardware from major brands supports 4-wire installations.

Best for: Properties with existing 4-wire cabling where the owner wants a reliable, straightforward upgrade path.

IP-Based Intercom Systems

IP intercoms connect over your local network via Cat5e/Cat6 Ethernet or Wi-Fi. They offer the most functionality: HD video, two-way audio, smartphone app access so you can answer the door from anywhere, and deep integration with CCTV and access control systems. Most new residential and commercial intercom installations in Perth are now IP-based.

Best for: New builds, full system upgrades, commercial properties, strata, and anywhere integration with access control or CCTV is required.

Intercom Brands: What We Install and Why

After more than 30 years installing security systems across Perth, our technicians have worked with every major intercom brand. Here's how the leading options compare for different property types:

Aiphone — Residential and Strata

Aiphone is our most frequently specified brand for Perth homes and strata buildings. Their GT series (2-wire video) and IX series (IP) are reliable, well-supported, and backed by a strong Australian distribution network. For residential properties with existing 2-wire cabling, the Aiphone GT series is often the cleanest upgrade path — HD video over existing wire, no rewiring required. For strata buildings with multiple apartments, the IX series handles multi-tenant configurations well.

2N — Commercial and High-End

2N (pronounced "two-and") is the benchmark for commercial IP intercoms. Their Helios IP range is specified on commercial buildings, office entries, and high-security sites across Perth. 2N units integrate natively with most major access control platforms, support video management systems (VMS), and handle multi-tenant configurations for strata and multi-tenancy buildings. Build quality is excellent — stainless steel vandal-resistant housings designed for high-traffic entries.

Jacques — Residential, Strata, and Commercial

Jacques Technologies is an Australian brand that covers residential, strata, and commercial applications. Well-regarded for reliability and local support, Jacques systems are a practical choice for Perth properties where Australian-made and serviced equipment is preferred. Their range covers 2-wire, 4-wire, and IP technologies.

Dahua — Good Value IP Video

Dahua's IP video intercom range offers solid performance at a more accessible price point. For Perth residential and light commercial properties where budget is a factor but IP video functionality is required, Dahua is a practical option. Their VTH (indoor monitor) and VTO (outdoor station) range is widely installed and well-supported locally.

DoorBird — Premium Residential

DoorBird is the high-end residential choice. German-engineered, with premium materials, a polished app, and deep smart home integration (works with Apple HomeKit, Google Home, Amazon Alexa, and most smart home platforms). DoorBird is priced accordingly — it's the right choice for high-value Perth homes where aesthetics and smart home integration matter more than cost. Excellent build quality and a strong track record in the Perth luxury residential market.

Axis — Commercial and Enterprise

Axis intercoms are specified on commercial sites where integration with their wider CCTV and access control ecosystem is the priority. For Perth properties already running Axis cameras and access control, the Axis A8207-VE network video door station is a natural fit — it integrates directly with Axis Camera Station and major VMS platforms.

Ajax Doorbells

Ajax Systems — best known in Perth for their wireless alarm platform — also offer a video doorbell that integrates with the Ajax ecosystem. For properties already running Ajax alarms, the Ajax DoorBell connects directly to the Ajax app alongside alarm zones and sensors, with indoor monitoring on a Samsung tablet running the Ajax app. A convenient option if you're already on the Ajax platform and want unified control from one interface.

House Intercom Systems: What Perth Homeowners Need to Know

For a standard Perth house, the intercom decision usually comes down to three questions:

1. Do you have existing wiring? If there's already a 2-wire or 4-wire intercom run to your front gate or door, you can often upgrade the hardware without any new cabling. If there's no existing cabling, you'll need a new cable run or a Wi-Fi based system.
2. Do you need a door release? If you want to unlock a gate or door remotely from the indoor monitor, you'll need an electric strike or magnetic lock installed — this is a more involved job than a simple audio intercom, but gives you full remote access control.
3. Do you want smartphone access? Most modern IP video intercoms let you answer the door from your phone when you're not home. Useful for deliveries, tradespeople, and general visibility. If this is important, make sure the system you choose has reliable app connectivity — DoorBird, Aiphone IX series, and 2N all have well-regarded apps.

Strata and Multi-Tenancy Intercom Systems Perth

Strata and apartment buildings have more complex intercom requirements than single-dwelling properties. A multi-tenant intercom system needs to:

• Allow a visitor to call a specific apartment from the building entry
• Support multiple indoor monitors across different apartments
• Give building management master access to all units
• Handle tenant turnover — adding and removing residents without a technician visit, ideally
• Integrate with the building's gate or lobby door access control

Aiphone IX series, 2N Helios, and Jacques are the three brands most commonly specified for Perth strata intercom systems. All three support multi-tenant configurations and integrate with electric strike locks at building entries. For larger buildings with 20+ apartments, 2N and Aiphone IX offer the most scalable management platforms.

Intercom Integration with Access Control and CCTV

A standalone intercom — call, speak, press a button — is a simple and effective tool. But IP-based intercom systems can go much further when integrated with your wider security setup:

• Access control integration: The intercom door release can activate an electromagnetic lock or electric strike connected to your access control system, giving you a full audit trail of every visitor entry event.
• CCTV integration: When the intercom is triggered, your CCTV system can automatically begin recording the entry camera, or flag the event in your video management system. For commercial sites with after-hours visitor access, this is particularly valuable.
• Alarm integration: On properties with monitored alarm systems, intercom events can be linked to alarm disarm schedules — so a verified visitor entry doesn't trigger an alert to your monitoring centre.

For Perth properties where integration is a priority, we recommend looking at your access control platform first, then choosing an intercom that natively supports it. See our guide to access control systems in Perth for a full overview of how access control and intercom work together.

Upgrading an Existing Intercom System

Many Perth homes and commercial properties have ageing audio-only or low-resolution analogue video intercoms. Upgrading is usually straightforward — the main variable is your existing wiring:

Intercom Installation in Perth: Licensing and What to Expect

In Western Australia, intercom systems that integrate with electric locks, access control, or monitored alarm systems fall under the Security and Related Activities (Control) Act 1996. Any installer connecting an intercom to an electromagnetic lock, electric strike, or alarm system must hold a current WA security licence.

A standard residential intercom installation typically involves:

1. Site assessment — confirming existing wiring, entry point locations, and door hardware requirements
2. Hardware selection — outdoor station, indoor monitor(s), and lock hardware if required
3. Cabling — using existing runs where viable, or running new Cat6 or 2-wire
4. Lock installation — electric strike or magnetic lock if door release is required
5. System commissioning — programming, app setup, and user handover

Commercial and strata installations follow the same process but add multi-tenant programming, access control integration, and often a more involved commissioning phase to configure apartment directories and building management access levels.
