Apartment intercom systems in Perth control who enters a building, how residents communicate with visitors and whether access is granted remotely or at the door. For strata buildings, body corporates and multi-unit complexes, the intercom setup is the first layer of access security for every resident in the building.
What Is an Apartment Intercom System?
An apartment intercom system connects a door station at the building entrance to individual units inside, allowing residents to see or speak with a visitor before releasing the door lock. Modern systems support audio-only, audio and video, or full app-based access where residents can answer the door remotely through a smartphone app. The door station at the entry typically pairs with an electronic lock release, which can be triggered by the resident or, in newer systems, by a PIN code or proximity card.
Types of Intercom Systems for Perth Buildings
The right system depends on the building’s construction, the number of units and whether cabling from a previous system is still usable.
Wired video intercoms are the most common choice for new apartment builds and medium to large complexes in Perth. They deliver consistent performance, clear video and reliable audio without dependence on a Wi-Fi network. For buildings currently being constructed or undergoing significant renovation, wired systems allow cabling to be run cleanly before walls are finished. This is particularly relevant for heritage apartment conversions in areas like Fremantle, where older building stock often needs cabling planned around existing structural constraints.
Wireless intercoms suit retrofits where running new cables through finished walls is impractical. They are often used in smaller apartment complexes, townhouse groups and established Perth properties where the existing cabling is outdated or missing. App-based handsets replace traditional wall panels, reducing installation disruption and allowing residents to manage access from their phones.
Video intercom upgrades are among the most common requests for existing apartment buildings. Older audio-only systems that have been in service for many years can be replaced with a video door station and updated handsets without replacing the full wiring run in most cases.
Strata and Body Corporate Installations
Intercom installations in strata-managed buildings involve more than just the technical side. Access decisions in multi-unit buildings typically require body corporate approval, and the system needs to work consistently for all residents rather than being adjusted for one unit.
Coast to Coast Alarms works directly with apartment complexes, strata managers and body corporates across Perth, handling site assessments, system design, quotations and installation with minimal disruption to residents. For larger complexes with shared commercial areas such as basement car parks or common facilities, this often overlaps with broader commercial security system planning rather than residential intercom work alone. Work is scheduled to avoid peak access times, and handover includes a walkthrough so residents understand how the new system operates before the installer leaves.
Intercom Repairs and System Failures
Intercom faults in apartment buildings tend to affect all residents simultaneously, which makes a prompt response more important than in a standalone home. Common fault types include failed door release mechanisms, damaged foyer stations after weather or vandalism, wiring faults in older buildings and handset failures in individual units.
Coast to Coast Alarms services most major intercom brands, including systems not originally installed by the company. For buildings with an intercom that is no longer manufactured, replacement components or a full system swap can be assessed during a site visit.
Integrating Intercoms With Access Control
Many Perth apartment buildings now combine intercoms with access control, allowing the door station to also manage proximity card access, keypad entry and visitor management logs. When integrated, a resident can be granted after-hours access via their card while a visitor rings through the video intercom for separate verification.
For Perth properties looking to upgrade both systems at once, Coast to Coast Alarms assesses the existing infrastructure and recommends configurations that avoid unnecessary duplication. Buildings that already run a residential alarm system in common areas can often integrate intercom access events into the same monitoring setup.

Frequently Asked Questions
What is the difference between a wired and wireless apartment intercom?
Wired intercoms use physical cables between the door station and unit handsets, offering reliable performance independent of Wi-Fi. Wireless intercoms use a network connection and suit retrofits where running new cables is impractical.
Can an existing apartment intercom be upgraded rather than fully replaced?
In most cases, yes. Existing wiring can often support a new door station and updated handsets, avoiding the cost of a full cable replacement. A site inspection determines whether the current infrastructure is usable.
How does strata approval work for an intercom upgrade?
Intercom upgrades in strata buildings typically require body corporate approval before installation proceeds. The installer can assist with a scope of works document to support the approval process.
Can residents open the door from their smartphone?
Yes. Modern video intercom systems include app-based access, allowing residents to see, speak with and remotely release the door for a visitor from anywhere with a mobile connection.
Does Coast to Coast service intercoms they did not originally install?
Yes. Coast to Coast Alarms (licence SA 05514) services most major intercom brands across Perth, including systems installed by other companies, and can advise on repairs versus replacement where components are no longer available.
