Types of Intercom Systems We Install in Sydney

IP Intercom Systems

IP (Internet Protocol) intercoms are the most advanced intercom systems we install. They run over CAT5 or CAT6 cabling, deliver true HD video and full-duplex audio, and integrate with cloud platforms, mobile apps and building management systems. An IP intercom is the strongest choice for new builds, larger homes and commercial sites that want every device on one network, and it makes future intercom installation and upgrades simple.

2-Wire Intercom Systems

2-wire intercoms are built for upgrading older Sydney apartment buildings without replacing existing cabling. Many strata buildings from 20–30 years ago already have 2-wire infrastructure running between units and the entrance panel. A 2-wire intercom system lets you move from an old audio handset to a modern video intercom while reusing those runs – a big saving in cost and disruption for a body corporate.

Wireless Intercom Systems

Wireless intercom systems transmit audio and video over WiFi or a dedicated wireless link, so there’s no need to run new cables through walls or ceilings. Wireless intercoms suit heritage homes, rental properties, granny flats and any property where cabling is impractical. We assess signal strength on site before any wireless intercom installation, so you don’t get wireless dropouts after we leave.

Video Intercom

Video Intercom Systems

Our video intercom systems let you see exactly who’s at the door before you unlock it. The door station camera streams to your indoor monitor and your smartphone, so whether you’re inside or away from the property, you can verify the visitor, talk to them, and grant or deny gate access with one tap.

Audio Intercom Systems

A simple audio intercom is still a solid fit where video isn’t needed – basic warehouse gates, internal door entry, or older apartment buildings on a tight budget. Audio intercom systems are the most affordable to install and maintain, and they still cover core entry security.

Our Intercom Security System Installation Services in Sydney

IP Intercom Systems

We install IP intercom systems that use internet protocols to deliver clear audio and video signals and communication. Perfect for residential and commercial properties, these IP intercom systems can integrate seamlessly with your smart home or business network.

2-Wire Intercom Systems

For buildings with existing wiring, our 2-wire intercom systems offer a cost-effective upgrade. Using just two wires for power and communication, they deliver reliable audio and video without extensive rewiring—ideal for older properties.

Wireless Intercom Security Systems

If running cables isn’t practical, we install wireless intercom systems that offer flexible, hassle-free communication across your property. These wireless systems are quick to set up and can include gate release controls, giving you remote access convenience.

Video Intercom

Video Intercom Systems

Our video intercoms let you see and speak to visitors before granting access, adding an important layer of security. Features include video messaging and visual verification, reducing unauthorised entry and improving overall safety.

Wireless Video Intercom System

We offer wireless video intercoms combining video surveillance with wireless networking. These provide high-quality video feeds accessible from anywhere on your property or via your mobile device, offering both convenience and security.

What is an Intercom System and How Does It Work?

An intercom system is two-way communication hardware that lets you speak with – and, on video systems, see – whoever is at your entry without opening the door. A typical intercom setup has three parts: a door station (the outdoor panel with a call button, microphone and camera), one or more indoor monitors inside the property, and the cabling plus power supply that connect them.

When a visitor presses the button on the outdoor panel, your indoor monitor rings. You answer the panel, see and speak to the visitor, and release the door or gate remotely. On a modern intercom system, that same call also reaches your phone, so you’re never tied to a wall-mounted panel.

The intercom can also tie into your access control systems, so fobs, keypads and the intercom all work together as one security setup. Understanding how each intercom system works is why a proper intercom installation matters – the hardware is only as good as the installation behind it.

Answer Your Door From Anywhere: Smartphone & Video Intercoms

The biggest shift in modern intercom installation is mobile answering. With a connected video intercom system, a call at your door or gate rings your phone, not just an indoor monitor. You see who’s there on video, speak to them, and handle remote unlocking – whether you’re in the backyard, at work, or away for the weekend.

That means you can let a courier leave a parcel, buzz in a tradesperson, or check a late-night visitor without ever opening the door. It’s genuinely useful for shift workers, families and anyone who travels. We’re honest at the site visit about which intercom systems support reliable mobile answering and which don’t, so you know exactly what your intercom installation includes before we start.

Next-Level Security and Communication with IP Technology

We recommend IP (Internet Protocol) video intercom systems because they offer great communication and security. These systems give you the ability to see and talk to anyone at your door, no matter where you are. The inside monitor of an IP system is often a modern touchscreen that allows two-way communication. You’ll need a stable internet connection to enjoy remote viewing so you can check visitors even when you’re not at home.

What to Look for in Your Ideal Intercom System

Choosing the right intercom system comes down to three things, and we’ll talk you through all of them before any intercom installation.

Here’s what to consider:

Size of Your Property

A small home or single unit needs one door station and one or two indoor monitors. A larger home might want indoor monitors in the living area and master bedroom, while an apartment block or commercial site needs a multi-unit panel and an intercom system designed for many users. We size every intercom installation to the property so you’re not over- or under-spending.

Features You Need

The features worth weighing up are mobile app integration so you can answer and unlock from your phone, access control systems integration so the intercom, fobs and keypads work as one, wide-angle cameras for a full view of the entry, WiFi and RFID connectivity, and cloud-based management for remote control and updates.

Budget

Audio intercoms are the most cost-effective; HD video and IP intercom systems cost more but deliver far more capability. The other cost factors in any intercom installation are the number of indoor monitors, whether we can reuse existing cabling, and the type of entry – a front door is simpler than a driveway gate that needs to tie into a gate motor.

Intercom Systems for Strata Buildings & Apartment Blocks in Sydney

Sydney has thousands of strata buildings still running 20 or 30-year-old buzzer intercoms that no longer meet resident expectations. Calls drop. Door release fails. Speakers buzz. Residents lose FOBs and need locks changed. We specialise in upgrading these older buildings to modern HD video intercom systems with smartphone integration, without ripping out the existing cabling or disrupting residents.

Here are some key benefits:

Better Security

A video intercom system helps you keep an eye on the front door. It allows you to talk to visitors and decide if you want to let them in. Many modern systems come with HD cameras that let you see, even at night, thanks to infrared capabilities.

Keep an Eye on Family

If you have young kids or elderly relatives, you can use your intercom to check on them from the comfort of your home. This is especially handy if they’re outside or in another part of the house.

Convenience

With features like remote access and the ability to unlock doors or gates, an intercom makes your home more secure and easier to manage, especially for those with limited mobility.

Track Deliveries

Worried about stolen packages? With a video intercom, you can talk to delivery drivers and make sure your parcels are left in a safe spot. Plus, you can review footage later if a package is stolen.

Intercom Repairs, Upgrades & Maintenance in Sydney

Not every job is a brand-new installation. We also repair and upgrade existing intercom systems across Sydney homes and businesses. If your intercom has stopped working, has a faulty panel, a dead power supply or wiring issues, our team can repair it and get your home security working again – often without a full replacement.

Upgrades are just as common as a new installation. Many homeowners want to move an old audio handset up to a video intercom, and most strata buildings want to modernise an ageing entrance panel. We assess what can be reused, recommend the right upgrade path, and carry out the installation with minimal disruption.

Regular maintenance services keep your intercom system reliable year after year, so small signal issues are fixed before they leave you locked out of your home.

Tailored Security Solutions for Every Industry

We understand that large industrial and warehouse sites need robust communication and secure access management. Our wired intercom systems connect key entry points, helping your team coordinate effectively in challenging environments while maintaining tight security.

In commercial offices, our intercom systems improve visitor management and internal communication. They help your staff quickly connect with reception or security, while controlling access to sensitive areas to keep your business safe.

How We Install Intercom Systems

Initial Consultation and Assessment

We start by understanding your security and communication requirements, then inspect your property to identify the best intercom setup.

Based on your needs, we create a tailored plan outlining device locations, features, and integration points.

Our licensed technicians install and configure all components with minimal disruption, ensuring seamless operation.

We rigorously test your new system and provide hands-on training so you can use it with confidence.

What an Intercom System Can Do for Your Property

An intercom system is more than just a convenience—it’s a powerful tool to increase your property’s security. It lets you talk to visitors before you let them in, which is especially helpful for families, elderly individuals, or anyone who needs extra protection.

Benefits of an Intercom System:

Restricted Access

Use video or audio to verify visitors before granting them entry, keeping your home safe from unwanted guests.

Simplified Communication

No need to physically answer the door. You can chat with visitors without leaving your room.

Evidence for Security

Recorded footage of interactions can help you if you ever need evidence for an insurance claim or to report suspicious activity.

Insurance Discounts

Many insurance companies offer lower premiums for homes with intercom systems, which can save you money in the long run.

Our Other Security System Installation in Sydney

Alarm systems enhance safety by identifying unauthorised access and immediately notifying you. Equipped with motion detectors, door/window sensors, and panic buttons, our monitored systems provide real-time alerts and 24/7 monitoring for comprehensive security.

Intercom systems are essential in managing entry and increasing communication in the building. Be it for strata buildings, offices, or gated communities, our intercom systems allow you to easily verify the visitor and then give him access or deny him from wherever you are.

Just had two fine gentlemen from Sydneywide Security over today for a 4 camera (2 PTZ + 2 Turret) 24/7 PoE NVR system I bought from a major retailer! No worries, no fuss at all, even when I changed my mind about placement for one of the PTZ! Courteous, knowledgeable and respectful, they did the hard yards, cleaned up after themselves, even cheerfully moved their service vans for the Mrs. when she had get to her doctor's appointment!

I spent about a month looking for certified installers in the Sydney area, most offered system + install (but mine was BYO), some didn't even get back to me (which is likely a good thing!). I even asked my friends and colleagues - none had any recent dealings with professional installers - well I KNOW who I will recommend to them now!

Professional, trustworthy and attentive, Sydneywide Security made this experience stress-free! Thanks guys!

⭐⭐⭐⭐⭐

Moe recently visited my property to conduct repairs and servicing on our home security, and the experience was outstanding from start to finish. He was professional, punctual, and extremely knowledgeable.

The repair process was seamless, with no unnecessary disruptions and he had no issues coming out a second time to address my concerns.

We are a 179 apartment complex made up of 12 residential blocks (in 5 towers) ranging from 3 to 5 stories; Sydneywide Security were chosen to look after the upgrade of our CCTV and did an excellent job.

We then tasked them with upgrading our Intercom and Access Control systems, a major investment not only in terms of funds but also resources as accessing all units over a 4 week period was never going to be an easy task.

Under Chris’s leadership his installation team of Moe and Chris 2.0 did a stellar job assisting in wrangling access to all the apartments despite the language barriers due to the large number of non English speaking residents in our complex; including juggling the changing access needs that tenants imposed.

The systems were installed professionally, any issues were promptly sorted out and the project ran 100% to budget and timelines. We had zero complaints from owners and residents about the workmanship or workers on site which was very pleasing.

Overall as chairman of the OC I was very pleased with the outcome and would highly recommend Chris and his team to other apartment complexes for the installation and maintenance of intercom, access control and CCTV systems.

A single word of caution, and this is not directed to Chris or his team as it’s completely outside of their control or remit, these types of upgrades do require a significant time investment by the Owners Corporation, be mindful of this when budgeting and allow for additional schedule B costs from your strata manager.

Frequently Asked
Questions

Basic audio intercoms start from $695 installed. Wireless video intercoms for a home typically run $1,200 to $2,500. HD video intercoms with smartphone integration sit between $1,800 and $3,500. Strata IP system upgrades for a 10 to 50-unit building usually fall between $8,000 and $35,000, depending on brand and existing cabling. Every quote is fixed and itemised with no hidden costs.

Yes. Almost every modern intercom system we install includes a free smartphone app for iOS and Android. When someone presses the door station, the call rings on your phone wherever you are. You see live HD video, talk to the visitor, and unlock the door remotely with one tap. This works whether you are in another room, at work, or overseas, as long as your phone has internet.

Yes. Strata is one of our specialty areas. We work directly with strata committees, building managers and owners’ corporations to upgrade outdated buzzer systems to modern HD video platforms. We can usually reuse existing 2-wire cabling, which means full building upgrades can be completed in 3 to 5 working days with minimal disruption to residents.
We coordinate AGM presentations, write itemised quotes for committee approval, and handle resident communication.

A single home intercom is typically installed in half a day. A small business with one or two door stations takes a full day. A 10 to 30 unit strata building upgrade is usually 3 to 5 working days. Larger commercial sites and multi-building strata complexes are scheduled across 1 to 2 weeks. We confirm the exact timeline in writing before starting work.

In most cases, yes. Many older Sydney buildings have 2-wire cabling that can be reused with modern 2-wire intercom systems. We can also use wireless intercoms in heritage properties or buildings where running new cable is not practical. During the free site assessment, we test your existing infrastructure and tell you exactly what can be reused and what needs replacing.

Yes. Modern IP and 2-wire intercoms integrate with most major CCTV brands (Hikvision, Dahua, Bosch), alarm panels (Bosch, Inner Range, Paradox), and access control platforms (Paxton, Inner Range, HID). When a visitor presses the door station, the system can trigger your CCTV to record, send a mobile alert, and log the event. We assess your current setup during the site visit and recommend what works best.

With modern FOB-based intercom systems, you simply log into the management dashboard or call us, and we deactivate the lost FOB in seconds. The credential immediately stops working at the door. You then issue a replacement FOB. Unlike traditional metal keys, there is no need to change locks across the building. This is one of the biggest practical advantages of upgrading from older keyed entry systems.

Most professional intercom systems we install include backup battery options that keep the system running for 4 to 24 hours during a power outage, depending on the model. For strata buildings and commercial sites where continuous operation is critical, we recommend battery backup or UPS integration. We discuss the right backup option during the site assessment.

For single dwellings and small commercial sites, yes. Modern wireless intercoms use dedicated frequencies or your home WiFi and deliver clear HD video and audio. For large strata buildings, hospitals, schools and industrial sites, we still recommend wired or 2-wire systems because they are more resilient against interference and signal drop. Our technician will recommend the right type for your property during the assessment.

Yes. We provide on-site repairs, scheduled maintenance and emergency call-outs across Sydney. If your existing intercom is buzzing, dropping calls, failing to release the door, or showing video issues, we can usually diagnose and fix on the same visit. We service all the major brands, including Aiphone, BPT, Comelit, Hikvision, Dahua, Akuvox, Fermax and Urmet. Annual maintenance plans are available for strata buildings and commercial sites.

If the intercom is part of a security system or controls access to a building, yes. NSW requires installers to hold a current Security Licence (Class 2). Sydneywide Security holds a Master License NSW 000105739, is fully insured, and our technicians are trained on every major intercom brand. Using a licensed installer also matters for insurance purposes and for strata compliance.

Yes. Most modern intercoms support multiple indoor monitors and unlimited smartphone connections. Common setups include a main monitor in the kitchen or living room, a second monitor in the master bedroom, plus the smartphone app for every household member. For larger homes and multi-storey properties, we can place monitors on each floor.

For homes, a modern HD video intercom with smartphone integration is now expected by buyers in many Sydney areas, particularly for properties over $1.5M and any property marketed as smart-enabled.

For strata buildings, upgrading from a 20-year-old buzzer to a modern IP system improves resident satisfaction and is increasingly raised at AGMs as a quality of life issue. The exact value uplift depends on the property, but the resale and rental appeal is consistently positive.
