For a driveway gate on a luxury home, choose video. An audio intercom lets you hear who is at the gate. A video intercom lets you see them, check them against what they say, and keep a record. Audio still has a place on low-traffic, low-risk entries, but on a gate that protects a high-value property it is the weaker choice, and the gap in cost is small next to the cost of the gate itself.
This guide is written for Melbourne homeowners, builders, developers and architects specifying an entry. It covers what each system does, where audio is still enough, how wiring and gate automation change the decision, and the privacy and installation traps that catch people out.
TL;DR
- Video adds visual confirmation before you open the gate. ASIAL describes audio-only intercoms as increasingly obsolete for building security.
- Audio-only can suit a low-traffic, low-security entry, such as a secondary pedestrian gate on a rural block.
- On a heritage or finished home, a 2-wire digital video system can avoid running new network cable through the walls.
- A camera aimed at a neighbor's door or a shared path can cause a legal problem. Set the field of view before you fix the unit.
- The intercom must release the gate through a proper relay, and the gate needs its own safety sensors. Plan both with the gate, not after it.

What actually separates video from audio
Both systems do the same basic job. A visitor presses a button at the gate pillar, a station inside the home rings, you talk, and you press a button to release the gate or door. ASIAL's fact sheet describes an intercom as a two-way communication system connected to door locks, and sometimes lift levels, that lets a visitor call and be let in.
The differences are these:
| Feature | Audio intercom | Video intercom |
|---|---|---|
| Hears the visitor | Yes | Yes |
| Sees the visitor | No | Yes, usually in color on a screen or phone |
| Verifies identity | Voice only, easy to bluff | Face, vehicle, parcel, uniform |
| Event record | Rarely | Image memory or log on most models |
| CCTV integration | Limited | Possible on IP systems |
| Phone answering | Some models | Common on current models |
| Upfront cost | Lower | Higher |
| Privacy exposure | Low | Higher, needs a considered camera angle |
The security gap is the key point. With audio alone, the only thing standing between a stranger and your driveway is a voice that you may not recognize. A courier, a tradesperson you have not met and someone with bad intentions all sound plausible through a speaker. Video removes the guesswork.
When audio is still enough
We do not dismiss audio. ASIAL's guidance frames the video-or-audio choice as a question of security risk appetite, and describes audio as acceptable for low-traffic or low-security areas. A few situations fit that description:
- A secondary gate that is rarely used, such as a side access to a service yard, where a second camera adds little.
- A property with a staffed or monitored front entry, where someone else has already verified the visitor.
- An existing audio system in good condition that you are extending, where the budget is better spent on the gate and automation.
- Extreme privacy sensitivity, where a camera would look onto a shared laneway you do not want to record.
For your main driveway gate on a boutique home, a development entrance or a commercial frontage, those exceptions rarely apply. A gate is the first line of defense. It is also the most visible element of the property, and the intercom lives on it permanently.
Why video is the default for luxury entries
Three practical benefits matter more than any feature list.
You verify before you release. Seeing the person, and the vehicle behind them, is the single biggest improvement over audio. If you are not home, a smartphone app lets you do the same from anywhere. ASIAL notes that modern video intercoms give one-way visual confirmation before a door or lift is released remotely.
You get a record. Many video units store an image of each call. If a delivery goes missing or someone tampers with the gate, you have a time-stamped picture, and on IP systems the footage can sit alongside wider CCTV. Integration guidance from an access control guide for apartment buildings makes the same point: access control on its own logs entries but gives no visual context, and pairing it with intercom and CCTV fills that gap.
It matches what buyers expect. Phone-enabled intercoms that let residents see visitors and release gates remotely are now the benchmark for high-end residential projects in Australia, according to the same ASIAL material. A premium gate with a dated voice box on the pillar undercuts the design.
Wiring: the choice that drives cost and finish
Most people compare video and audio by screen and price. In practice the cable run often decides the project, especially for a retrofit.
2-wire digital systems
Many people assume video intercoms always need network cable. They do not. ASIAL notes that 2-wire digital systems are often the preferred choice for retrofitting luxury homes and heritage properties, because they carry high-definition video and audio over existing two-core cabling. If your home already has an old audio intercom cable between the gate and the house, there is a good chance it can be reused. That avoids chasing new cable through finished walls, gardens and paving, and it protects the finish you paid for.
IP and app-based systems
IP systems run over your network, which gives you phone answering, multiple stations and integration with other security. They are powerful, and they also depend on infrastructure. ASIAL cautions that these systems need robust internet connectivity and professional IT management to stay secure, while traditional hard-wired systems do not need an internet connection and are inherently more resilient to cyber attack. If you choose IP, someone has to own the updates, passwords and network segmentation. If that is not you, ask your installer who it will be.
Manufacturers publish both types. Aiphone's JO Series is a 7-inch touch-button video intercom with an app and Wi-Fi for residential use, which shows the sort of phone-linked residential unit now available in Australia.
Wireless units
Wireless video intercoms are easy to fit, and they can suit a temporary arrangement or a rental. On a bespoke gate, we generally prefer a cabled connection to the pillar: it avoids dropouts at the point where reliability matters, and it keeps the design clean.
How intercom and gate automation fit together
The intercom does not open the gate by itself. It sends a release signal to the gate controller, and the controller runs the motor. Getting that handoff right is installation work, not a product choice.
One mistake is common and expensive. Intercom stations often provide only a dry contact. If an installer tries to power an electric strike or magnetic lock directly through the intercom's internal terminals, the main board can be damaged. Aiphone's product documentation points to using a dedicated isolation relay, and gives the RY-18L as an example, so the intercom switches the relay and the relay switches the load. Repairs after that kind of failure are typically not covered by warranty.
Two more points belong in the same conversation:
- Safety sensors. Whatever opens the gate, the gate must also stop when something is in its path. Our guide to mounting gate safety sensors at 600 mm explains the detail installers check.
- Standards. ASIAL points to AS/NZS IEC 60839.11.1:2019 as the standard defining security grades and performance requirements for electronic access components. It is listed with ASIAL's electronic security standards. Ask your installer which grade their components meet.
If you are adding access control to an existing gate, our checklist for retrofitting gate access to Australian standards walks through the options in more depth.
Privacy: the problem nobody puts in the brochure
A video intercom is a camera. In Melbourne, that matters most on narrow streets, shared driveways and townhouse developments, where a gate pillar can sit a few meters from a neighbor's front door.
The legal picture varies by state. In Victoria, the Surveillance Devices Act 1999 governs optical surveillance. A Victorian electrical firm's summary of the Act is not something we link to as our reference, so for a firm answer, ask a lawyer or check with the Victorian regulator about your specific camera. What we can say with confidence is how the issue plays out in practice. A Mallen Services article on NSW tribunal scrutiny of strata doorbell cameras reports that these devices are being examined closely when they capture a neighbor's door or common corridors, and that forced removal is possible. That article concerns New South Wales law, so do not treat it as the Victorian position, but the principle carries over: the problem is where the camera looks, not how much it cost.
Practical steps:
- Choose a unit with an adjustable or narrow field of view.
- Aim it at the visitor's position at the gate, not the street or the neighbor's boundary.
- Use privacy masking if the unit offers it.
- If the gate sits in an owners corporation, check the rules before you buy.
- Ask whether the unit records audio. Recording private conversations can raise separate issues from video.
Lifespan and total cost
Price tags mislead here. ASIAL reports that high-quality systems typically last 12 to 20 years, while lower-tier systems often fail between 5 and 12 years. For a gate you plan to keep, a cheaper audio unit replaced twice can cost more than one good video system installed once.
What drives the final figure on a gate project:
- Hardware grade, including weather rating, vandal resistance and screen quality.
- Cable condition: reusing a 2-wire run is cheaper than new cable through finished landscaping.
- Number of indoor stations and whether phones are included.
- Integration with the gate controller, door locks and CCTV.
- Commissioning and testing time.
We do not publish fixed prices because each gate and entry is different. We scope the intercom as part of the whole entry, so you see one number for the project.
A short decision guide
- Is this your main gate, or does it protect a high-value property? Choose video.
- Is there existing 2-core cable you can reuse? Look at a 2-wire digital video system first.
- Do you want to answer from your phone? Choose a system with an app, and plan who manages the network.
- Does the camera risk looking at a neighbor? Fix the angle and masking before installation.
- Is the access secondary and low risk? Audio may be enough, but ask whether upgrading later would mean new cable.
Our perspective
We build gates, so we see the intercom from the pillar out. The most common regret we hear is not that someone chose video over audio. It is that the intercom was chosen last, after the gate was designed, and the pillar had no room for it, no conduit and no clean route for cable.
Our view is that the intercom is part of the entry design. The unit should sit at the right height for a driver, within reach from a car, and in the correct material and finish for the pillar. The wiring should be planned before the pillar is built. The release should go through a proper relay to the gate controller. And the camera should look at the visitor, not at the street.
We lean toward video on every main entry, because a luxury gate with a voice-only speaker asks the owner to trust what they hear. Where a client wants elegance without bulky hardware, we choose flush or slimline units and integrate access control into the architecture. For retrofit work on heritage homes, we look for reusable cabling first.

Planning your entry with Gatecon
If you are commissioning a driveway gate in Melbourne, we design the gate, automation and access control together so the intercom suits the architecture rather than being bolted on. See our architectural gates and the matching designer fencing, or look at the suburbs we serve and tell us about your project. For more on app control, read our guide to smart home gate control and safety.
One more point from ASIAL: for complex, high-value installations, it recommends engaging qualified ASIAL Member security companies. Ask any installer about licensing and membership before you sign, and ask who will commission the door release.
FAQ
Is a video intercom worth the extra cost over audio?
On a main driveway gate, yes. You see who is there before you open, you can answer from your phone on many models, and you get a visual record. The extra cost is small beside the gate, and ASIAL treats audio-only as increasingly obsolete for building security.
Can I upgrade from audio to video later?
Sometimes. If the existing cable is two-core and in good condition, a 2-wire digital video system may reuse it. If not, you may need new cable, which is why we recommend deciding before the pillars and paving are finished.
Does a video intercom need internet?
Not always. Hard-wired systems work without an internet connection. App-based and IP systems need a reliable connection and proper network management, which is the trade-off for phone answering.
Can my intercom camera get me into trouble with neighbors?
It can if it captures a neighbor's door, window or a shared space. Tribunals have scrutinized this in strata settings. Aim the camera at the visitor, use masking where available, and seek legal advice if your gate sits close to a neighbor.
