Video doorbells are designed and marketed around North American wiring. Over there, a low-voltage transformer feeding a mechanical chime is standard in most houses. In Australia, what sits behind your doorbell button could be an 8V AC plug pack in the hallway cupboard or a transformer mounted in the meter box. It could also be a battery-powered wireless chime, or nothing at all beyond two thin wires that stopped working in 2009.
Getting this right matters, because the failure modes are unglamorous: a doorbell that boots, rings once and browns out; a mechanical chime that hums continuously; or a transformer that runs hot because it is undersized.
Start by identifying what you actually have
Before you buy anything, spend twenty minutes tracing the existing system. There are four common scenarios in Australian homes.
Battery chime, wireless button. Very common in homes built or renovated in the last 20 years. There is no wiring at the door at all. A wired video doorbell is not a drop-in here.
Plug-pack transformer. A small unit plugged into a Type I socket in a cupboard, laundry or roof space, with bell wire running to the door. Look for a label: it should show the output voltage, whether the output is AC or DC, and a VA or amp rating. Older chime plug packs vary widely, so read the label rather than assuming.
Meter-box or switchboard transformer. A DIN-rail or surface-mounted transformer hard-wired to 240V. This is fixed electrical work — see below.
Dead wires. Two conductors at the door with nothing energised behind them. Worth testing with a multimeter on AC volts before you assume anything.
Photograph the transformer label and the chime unit's terminals. Those two photos answer most compatibility questions.
Why the voltage specs on the box rarely match
Most mains-powered video doorbells specify something in the range of 8-24V AC, and many draw meaningfully more than an old mechanical bell button ever did. Ring's wired models and Nest's wired doorbell both publish minimum VA ratings as well as voltage ranges. Ring's Australian support site lists 8-24V AC at 8-40VA for the Ring Video Doorbell Wired and 16-24V AC at 10-40VA for its Pro and wired-variant models (Ring AU). Google asks for a transformer rated 16-24V AC, 10-40VA for the Nest Doorbell (wired, 2nd and 3rd gen) (Google Nest Help). The VA figure is the one people ignore, and it is usually what causes reboot loops. These specs change between generations, so check the page for your exact model before buying.
Three Australian-specific traps:
AC versus DC. Plenty of local plug packs are DC. Several video doorbells will only accept AC, and connecting DC to an AC-only input can damage the unit. Check the doorbell's manual, not a forum post.
Undersized transformers. An 8V AC plug pack rated at 5VA might have happily run a ding-dong chime for 30 years. A camera with night vision, a speaker and a Wi-Fi radio is a different load entirely.
Imported transformers. A 16V AC transformer bought from a US seller will have the wrong plug and may not carry Australian approvals. Under the national Electrical Equipment Safety System, in-scope electrical equipment must not be sold in Australia unless it carries the RCM (EESS). Ask the seller to confirm that a plug pack is RCM-marked before you buy, and don't treat a travel adaptor as a permanent fix.
If you are running a plug-pack transformer from a socket in a cupboard, a smart plug on that socket gives you remote power cycling. That is genuinely useful when the doorbell locks up while you're away and you'd otherwise be asking a neighbour to unplug something.

Don't automate it on a schedule, though. A doorbell that's off between 11pm and 6am is a security device that isn't.
What you can do yourself, and what needs a licensed electrician
This is the part worth being blunt about. Anything connected to 240V mains is a licensed electrician's job. That includes installing or replacing a transformer that is hard-wired into a meter box or switchboard, running new mains cabling, or altering an existing hard-wired chime circuit. Do not do it yourself, regardless of what a YouTube tutorial from Ohio shows. The detail of what counts as licensed electrical work, and the penalties, differ between states and territories, so check with your state's electrical safety regulator.
The extra-low voltage side — the bell wire between the transformer output and the door button, typically 8-24V — is where the rules get less clear-cut. How extra-low-voltage work is treated differs by state, and manufacturers set their own conditions. Ring's Australian support page says installation and wiring of its video doorbells must be performed by a licensed electrician in Australia and New Zealand (Ring AU). Check your state's electrical safety regulator and your doorbell's install guide before touching the bell wire yourself, and if the wiring shares a cavity or enclosure with mains cabling you should not be in there.
The safe, boring, defensible path for most people:
- Use a plug-in transformer supplied with, or approved for, your doorbell, plugged into an existing socket.
- Have an electrician install anything that connects to the switchboard, and ask for the certificate of electrical safety or equivalent paperwork for your state.
- Isolate at the switchboard before touching a transformer, even a low-voltage one, because you cannot be certain what's behind it.
Renters have an extra layer. In Victoria, Consumer Affairs Victoria lists a wireless doorbell among the changes renters can make without consent. But security cameras only qualify if they are easily removable and not hard-wired, and fixing hardware to exposed brick needs consent (Consumer Affairs Victoria). In NSW, you can make changes only if your lease allows it or your landlord gives written permission (NSW Government). Rules differ in other states, so check with your state tenancy authority before drilling anything.
Making the existing chime behave
Assuming power is sorted, the chime is the next hurdle.
Mechanical chimes (the hammer-and-bar type) generally work with wired doorbells, but the doorbell needs to pass enough current through the chime coil without holding it energised. Symptoms of a mismatch are a constant hum or a weak single note.
Electronic chimes (a speaker playing a tone) usually need a bypass module or diode kit. Ring says its Wired Doorbell Plus and Pro must be used with its Pro Power Kit. The kit fits inside the existing chime and can also be wired to bypass it (Ring). Other brands have their own adaptors. What's in the box changes between generations. Ring notes the Wired Doorbell Plus originally came with a Pro Power Cable and now ships with the Pro Power Kit v2 (Ring). So check the box contents listed for your exact model.
Long, thin bell wire is the third culprit. Older Australian bell wire is often very fine gauge and may run 15 metres or more from a cupboard to the front door. Voltage drop across that run can push a 12V supply below the doorbell's minimum under load. If the doorbell reboots when the motion light kicks in, suspect the cable before you blame the Wi-Fi.
There is also a legitimate option to skip the chime entirely: bypass it, mount the doorbell, and let smart speakers announce visitors. A speaker in the kitchen and another in the back room covers a typical house better than one chime in the hallway ever did, and you can adjust volume per room. If you want visitor alerts out on the patio, choose weatherproof outdoor speakers built for Australian conditions so they survive the summer heat and rain.

Check ecosystem compatibility first — announcement support depends on which doorbell brand and which assistant you're using, and some pairings are limited to app notifications only.
When wire-free is simply the better answer
If your investigation turns up a battery chime, no wiring, a switchboard-mounted transformer you'd need an electrician to replace, or a rental you can't modify, a battery camera or doorbell avoids the entire problem. You trade recharging every few months for zero electrical work.
The same logic applies to front-yard coverage more broadly. A doorbell watches the doormat; it doesn't watch the driveway or the side gate, and stretching a doorbell to do both usually disappoints.
Arlo Ultra 2 4K Spotlight Camera
Best for: Households already running an Arlo SmartHub or base station who want a wire-free 4K outdoor camera with a built-in spotlight
What we like
- Arlo lists a 4K lens with a 180-degree field of view, and the Australian listing adds 4K HDR and colour night vision
- Integrated spotlight that Arlo says can be switched on manually or triggered by motion or sound, plus a siren on the built-in speaker
- Wire-free and battery powered, with a magnetic charging cable; the Australian listing claims up to six months per charge
- Arlo's VMB5000 SmartHub has a microSD slot, giving a local storage option alongside the cloud
Worth knowing
- Sold as an add-on camera, so it needs a compatible Arlo SmartHub or base station (VMB5000, VMB4540, VMB4500 or VMB4000)
- Cloud recording sits behind a paid Arlo Secure plan
- At least one Australian retailer lists the Ultra 2 system as discontinued, with the Ultra 3 as its replacement
- Battery-life figures are a brand claim and depend on how often the camera records
Specification-wise, a wire-free spotlight camera covers the wider approach that a doorbell's narrow, vertically-oriented field of view can't. Note that ongoing cloud subscription costs apply to most brands, and battery life claims are typically stated for moderate activity — a camera facing a busy footpath will do considerably worse.
A short pre-purchase checklist
- Photograph the transformer label and chime terminals.
- Confirm AC or DC, voltage and VA against the doorbell's published requirements.
- Measure the bell wire run and note whether it looks like fine-gauge figure-8.
- Decide whether the chime is mechanical or electronic.
- Confirm 2.4GHz Wi-Fi signal strength at the door position, not at the router.
- If anything touches the switchboard, book a licensed electrician before you buy hardware.
Get those six answers first and the install is a 45-minute job. Skip them and it's a weekend, a return, and a second trip to Bunnings.
