Dash Cam Installation in Australia
There are four ways to power a dash cam in an Australian vehicle — and only three of them give you parking mode. This guide shows you exactly which one suits your car, your budget and your skill level, so you buy the right kit the first time.
The short answer
If you only want to record while driving: use the supplied 12V cigarette lighter cable. It is genuinely plug and play, takes about 15 minutes, and costs you nothing extra.
If you want parking mode (recording while the car is parked): you need constant power. That means an OBD-II power cable (plug and play, DIY-friendly), a hardwire kit into the fuse box (auto electrician recommended), or a dash cam battery pack (the safest option for your car battery, and the only realistic option for many EVs).
If you drive an EV, hybrid or a European car with a sensitive battery management system: a battery pack is almost always the right answer. Here's why.
The four ways to power a dash cam
Every dash cam is mounted the same way — high and central on the windscreen. The only real decision is where the power comes from. That decision determines whether you get parking mode, how long the install takes, and whether you need a professional.
1. Cigarette lighter (12V)
Plug the supplied cable into your 12V socket. The camera turns on and off with the ignition. No tools, no wiring, nothing permanent.
- Parking modeNo
- DifficultyBeginner
- Time15 min
- Extra cost$0 — included
Best for: leased and novated-lease cars, company cars, anyone who only drives and parks in a garage.
2. OBD-II power cable
Plugs straight into your car's OBD-II diagnostic port under the dash. Delivers constant power for parking mode with no fuse box work at all.
- Parking modeYes
- DifficultyBeginner
- Time20–30 min
- Extra cost$79–$89
Best for: most cars built from 1996 onwards where you want parking mode without an auto electrician.
3. Hardwire kit (fuse box)
Taps a constant circuit and an ignition-switched circuit in the fuse box using add-a-fuses, plus an earth to a chassis bolt. The cleanest, most permanent install.
- Parking modeYes
- DifficultyAdvanced
- Time45–90 min
- Extra costOften included
Best for: conventional petrol and diesel vehicles with an accessible fuse box, where you want the tidiest possible result.
4. Dash cam battery pack
A dedicated LiFePO4 battery that charges while you drive and powers the camera while you're parked. Your car battery is never drained.
- Parking modeYes (longest)
- DifficultyBeginner+
- Time20–60 min
- Extra cost$299–$468
Best for: EVs and hybrids, European and prestige cars, low-kilometre drivers, and anyone parking on the street overnight.
Installation methods compared
The honest version — including the downsides we'd tell you about over the phone.
| Method | Parking mode | DIY friendly | Drains car battery? | Typical parked recording time | The catch |
|---|---|---|---|---|---|
| Cigarette lighter (12V) | No | Yes | No | None — camera powers off with the car | You have zero protection while parked, which is when a lot of damage happens. |
| OBD-II power cable | Yes | Yes | Yes — with a low-voltage cut-off | Roughly 10–15 hours, depending on your battery's health | Brand-specific (a FineVu cable won't run a BlackVue). Some hybrids and EVs don't expose a usable OBD-II port. |
| Hardwire kit | Yes | Only if you're confident with auto electrics | Yes — with a low-voltage cut-off | Roughly 10–15 hours, depending on your battery's health | Choosing the wrong fuse circuit can disable car functions. Many modern EVs have no practical fuse box to tap. |
| Battery pack | Yes (longest) | Yes (via 12V socket) | No — completely isolated | Typically 24–30+ hours on a 1-channel camera | Highest upfront cost, and it needs somewhere to live (under a seat or in the boot). |
Still deciding between an OBD-II cable, a hardwire kit and a battery pack? This walks through the trade-offs of each.
Parking mode runtimes are indicative only. Actual time varies significantly with the camera model, resolution, whether you use motion detection or time-lapse, Wi-Fi and cloud settings, ambient temperature, and the age and health of your vehicle's battery.
What do you drive?
The right install method depends more on your car than on your camera.
Petrol or diesel, 2010–now
You have the most options. An OBD-II cable is the easiest route to parking mode; a hardwire kit gives the tidiest result if you're using an installer.
Our pick: OBD-II cable for DIY, hardwire kit if a professional is doing it. Add a battery pack if you park on the street overnight.
EV or hybrid
Many EVs have no owner-accessible fuse box, and the 12V auxiliary battery generally isn't being topped up while the car sits parked and asleep.
Our pick: a battery pack, every time. It removes the vehicle's 12V system from the equation entirely. Full EV section below.
Tesla
Tesla is the hardest car in Australia to hardwire. Model 3 and Model Y have no conventional owner-accessible fuse panel, and there's no standard plug-and-play OBD-II port.
Our pick: a battery pack charged from a 12V socket. Give us a call before you buy — Tesla builds vary by year.
European & prestige
BMW, Mercedes, Audi, Volvo and Land Rover often use expensive AGM batteries and intelligent battery sensors that don't appreciate a parasitic draw overnight.
Our pick: a battery pack. It's cheaper than replacing a European battery once.
4WD, ute or caravan tow vehicle
If you already run a dual-battery or DC-DC setup, you may have a clean auxiliary circuit to work from. Corrugations also mean cable routing and mount security matter more than usual.
Our pick: hardwire to the auxiliary system, or a battery pack for remote camping where the vehicle sits for days.
Fleet, van or truck
24V systems, multiple drivers and long parked periods change the maths. Most of our fleet cameras support 12V and 24V, and cloud-connected models let you pull footage remotely.
Dash cam installation in EVs and hybrids
Electric vehicles have quietly broken the standard dash cam install. Here's what's actually different — and what to do about it.
Every EV still has a 12V battery
This surprises a lot of people. Your EV's big high-voltage traction battery drives the wheels, but the lights, infotainment, locks, computers — and your dash cam — all run off a small conventional 12V auxiliary battery, exactly like a petrol car. On many newer EVs that 12V battery is lithium rather than lead-acid.
The difference is how it gets charged. A petrol car has an alternator that charges whenever the engine runs. An EV uses a DC-DC converter to trickle power from the traction battery down to the 12V battery — and that converter generally isn't running continuously while the car is parked and asleep. It wakes periodically, not constantly.
Why that matters for parking mode
If you hardwire a dash cam into an EV and leave it recording overnight, you're drawing from a small 12V battery that isn't being reliably replenished. Flatten it and you don't just lose the dash cam — on many EVs a dead 12V battery means the car won't wake up at all, and you're calling roadside assistance to get into your own vehicle.
Lithium 12V batteries add a second problem: discharge them too deeply and they can drop into a protection state that a workshop has to reset.
And often there's nothing to hardwire to
Several popular EVs simply don't give you a conventional owner-accessible fuse panel with a clean ignition-switched circuit. Tesla Model 3 and Model Y are the well-known example — power distribution is electronically switched rather than fused in a panel you can tap, and there's no standard plug-and-play OBD-II port either. Other brands vary: some EVs and hybrids built on more conventional platforms do retain a normal fuse box.
Before you buy
EV electrical layouts change between model years, and even between builds of the same model. If you drive an EV or hybrid, call us on (03) 9350 2605 before you order and tell us the exact make, model and build year. It takes two minutes and it's the difference between a camera that works and a box you have to send back.
The EV answer: a battery pack
A dash cam battery pack sidesteps every one of these problems at once:
- It charges while you drive and runs the camera while you're parked, so your EV's 12V battery is never the thing being drained.
- It doesn't need a fuse box, so it works in cars that have no practical one.
- It gives you far more parked recording time than the vehicle's 12V system realistically would.
- It can be installed by plugging into a 12V accessory socket — no auto electrician required.
Tesla owners — one more thing
Sentry Mode is good, but it isn't a dash cam replacement. It uses the car's exterior cameras only — there's no cabin camera and no audio, and footage quality and retention are on Tesla's terms, not yours.
An aftermarket dash cam gives you an interior-facing option, audio, your own memory card, and a system that keeps working independently of the car's software.
Dash cam battery packs explained
A dash cam without parking mode only protects you for the small fraction of the time you're actually driving. A battery pack is what makes 24/7 protection practical without gambling your car battery.
It charges while you drive
Connected to an ignition-switched supply — either through a 12V socket or hardwired — the pack tops itself up whenever the vehicle is running. Most short daily commutes are enough to keep it charged.
It powers the camera while parked
When you switch off, the pack takes over and runs parking mode from its own cells. Your vehicle's battery is completely out of the loop, so there's no parasitic drain and no low-voltage cut-off cutting your recording short.
It uses LiFePO4, not power-bank cells
Purpose-built dash cam packs use lithium iron phosphate chemistry, which handles far more charge/discharge cycles than the lithium-ion in a standard USB power bank and is more thermally stable — which matters in a car parked in the Australian sun.
Don't use a USB power bank
We get asked this a lot. A phone power bank is not designed for hundreds of deep charge/discharge cycles, isn't built to sit in a 60°C parked car through an Australian summer, and generally can't deliver stable enough current for a dual-channel dash cam. It's a fire risk and a false economy. Use a purpose-built LiFePO4 dash cam battery pack.

Should you DIY it?
Do it yourself if:
- You're using a cigarette lighter cable, an OBD-II cable, or a battery pack via the 12V socket
- You're comfortable tucking a cable into weather stripping and roof lining
- You're happy to take your time and test before tidying up
Get a professional if:
- You're hardwiring into the fuse box and aren't confident identifying circuits
- The job needs cable run behind the A-pillar (side curtain airbags live there)
- You drive an EV, hybrid or prestige vehicle and want it hardwired
- Your car is under warranty and you want the install documented
If you'd rather have it done for you, use a qualified auto electrician with dash cam installation experience — and ask them specifically whether they've done your make and model before. Not sure what your install actually involves? Give us a call on (03) 9350 2605 and we'll talk you through your options.
Where to mount a dash cam in Australia
The adhesive pad is a one-shot deal on most cameras. Dry-fit before you peel.
The rules that apply
There is no dash-cam-specific national law in Australia. Mounting is governed by the general road rule requiring a driver to have a clear view of the road and proper control of the vehicle, which every state and territory has adopted (Rule 297 of the Australian Road Rules), plus the usual vehicle standards about aftermarket fittings being securely mounted.
Victoria publishes the clearest official guidance we're aware of — Vehicle Standards Information 29, covering equipment fitted within the driver's field of view. Its practical advice is the same advice a good installer gives anywhere in Australia:
- Mount it behind the rear-view mirror, or up in the tinted band at the top of the windscreen, so it isn't taking up any of your actual road view
- Keep it out of the airbag deployment path
- Don't let it obscure the instrument cluster or your view of the road ahead
- Mount it securely — a camera that falls off in a crash is a projectile
This is general information, not legal advice. Requirements are set by each state and territory road authority and can change — check with yours if you're unsure. If you're in Victoria, VSI 29 is published by the Department of Transport and Planning.
Practical placement tips
- As high and central as it will go. Tucked behind the mirror is ideal — it's out of your eyeline and it's the best field of view.
- Can't fit behind the mirror? Go to the passenger side of the mirror, not the driver's side. Many newer cars have a driver-assist camera housing there that leaves no room anyway.
- Watch the ceramic dots. Mount too high and the black dotted band at the top of the windscreen will creep into the top of your footage.
- Check the wiper sweep. Sit the lens inside the area the wipers actually clear, or your rainy-day footage is useless.
- Clean the glass properly. Alcohol wipe, fully dry, before the pad goes on.
- Cold morning? Warm the adhesive pad in front of a heater vent first. Adhesive loses grip in the cold and that's the number one cause of a camera dropping off a week later.
Five mistakes we see every week
Pulling the A-pillar trim off
Side curtain airbags run down the A-pillar. You do not want a cable interfering with one. Tuck the wire into the rubber weather strip instead — it's easier and it's safer. If the cable genuinely has to go behind the pillar, pay someone qualified.
Buying the wrong OBD-II cable
These are brand-specific. A FineVu OBD-II cable will not power a BlackVue and vice versa. Check the camera brand before you order, or ask us.
Assuming the 12V socket stays live
Some cars keep the cigarette lighter socket powered with the ignition off, some don't. If yours does, a camera left plugged in will quietly drain the battery. Test it before you rely on it.
Peeling the adhesive before dry-fitting
Hold the camera up, check the angle on the screen or in the app, check the wiper sweep, then peel. Replacement adhesive pads are cheap but the afternoon you lose isn't.
Tidying the wiring before testing
Run it loose, start the car, confirm the camera powers up and parking mode arms, then tuck everything away. Everyone who skips this ends up pulling it apart again.

Dash cam installation FAQs
Can I install a dash cam myself?
Yes — for most people, most of the time. Mounting the camera and routing the cable to a 12V socket or an OBD-II port is genuinely straightforward and takes 15–30 minutes with no tools beyond a plastic trim tool or an old credit card. The only part we'd steer a novice away from is hardwiring into the fuse box, and removing A-pillar trim where the side curtain airbags sit.
Do I need parking mode?
Ask yourself where your car spends most of its life. If it's in a locked garage, probably not. If it's on a street, in a shopping centre car park, or in an unsecured work car park, then yes — a large share of the incidents our customers actually claim on happen while the car is parked and the driver isn't there. Hit-and-runs in car parks, trolley damage, keying, attempted break-ins. Without parking mode your dash cam is switched off for all of it.
Will a dash cam drain my car battery?
Not while you're driving. While parked, it depends on how you've powered it. OBD-II cables and hardwire kits draw from the car battery and rely on a low-voltage cut-off to shut the camera down before the battery gets too low to start the car — set that cut-off correctly for your battery type and it's generally fine on a healthy battery in a car driven regularly. If your battery is old, your car sits for days at a time, or you drive an EV, hybrid or European car, use a battery pack instead. It draws nothing from the vehicle while parked.
What's the difference between an OBD-II cable and a hardwire kit?
Both deliver constant power for parking mode. The OBD-II cable plugs into the diagnostic port under your dash — no tools, no fuse box, roughly 20–30 minutes, and it's completely reversible. A hardwire kit taps circuits inside the fuse box with add-a-fuses and needs an earth point; it's tidier and more permanent, but it's a job for someone who knows what they're doing. OBD-II cables are brand-specific and typically cost $79–$89; hardwire kits are usually included in the box.
Can I install a dash cam in a Tesla?
Yes, but not the conventional way. Tesla Model 3 and Model Y don't give owners an accessible fuse panel to hardwire into, and there's no standard plug-and-play OBD-II port. The practical approach in Australia is a dash cam battery pack charged from a 12V accessory socket, which gives you parking mode without touching the car's electrical architecture. Tesla builds change between model years, so call us on (03) 9350 2605 with your exact year and model before ordering.
Is Sentry Mode enough, or do I still need a dash cam?
Sentry Mode is a genuinely useful feature, but it isn't the same thing. It records from the car's exterior cameras only — there's no cabin camera and no audio recording. A dedicated dash cam adds an interior-facing option, audio, footage stored on your own memory card in a format you control, and a system that keeps recording independently of the car's software and settings. Plenty of Tesla owners run both.
How long will a dash cam record while parked?
Powered from the car's own battery via OBD-II or a hardwire kit, expect roughly 10–15 hours before the low-voltage cut-off shuts the camera down — less on an older battery. With a dedicated battery pack you're typically looking at well over 24 hours on a single-channel camera, and meaningfully less on a dual-channel setup because the second camera runs continuously too. Resolution, Wi-Fi and cloud features, motion detection versus time-lapse, and cold weather all move that number.
Where is it legal to mount a dash cam in Australia?
There's no dash-cam-specific law. Mounting is covered by the general requirement that a driver has a clear view of the road and proper control of the vehicle (Rule 297 of the Australian Road Rules, adopted in every state and territory), plus vehicle standards requiring aftermarket fittings to be securely mounted. In practice: mount it behind the rear-view mirror or in the tinted band at the top of the windscreen, keep it clear of airbag deployment paths, and make sure it doesn't obscure your view or your instruments. Victoria's Vehicle Standards Information 29 sets this out clearly and is a good reference wherever you live. Check with your state road authority if you're unsure.
Do I need a front and rear (2-channel) camera?
Rear-end collisions are one of the most common crash types in Australia and a front-only camera captures none of it. A 2-channel setup also covers you for tailgating, road rage from behind, and rear damage while parked. The rear camera doesn't need its own power source — it's fed power and data by the front camera through a single connecting cable, so the install is barely more involved. Most of what we sell is 2-channel for exactly this reason.
Can I move the dash cam to my next car?
Yes. You'll need a replacement adhesive mount (they're inexpensive), and if you hardwired it you'll need it removed and reinstalled. This is one of the underrated advantages of an OBD-II cable or a battery pack — both unplug and move across in minutes.
