VIOFO T340 4CH 4K+2K+2K+2K HDR Telephoto Dash Cam - 4x Zoom, IR Cabin, STARVIS 2

See Four Angles at Once, and Still Read the Plate Three Cars Ahead. The VIOFO T340 4CH is a four-channel dash cam with a 4x optical zoom telephoto camera

Here is the catch with every wide-angle dash cam. The lens that captures the whole scene is the same lens that shrinks a number plate to a smudge. At twenty metres a 140 degree front camera has spread that plate across a handful of pixels, so you finish up with clear footage of an incident and nothing that identifies the car which caused it. Bolting on more wide-angle cameras does not fix that. A different lens does.

Trusted AU store: We're an authorised Australian reseller, shipping from Melbourne within 24 hours^*. You get an 18-month warranty with no product registration required, local technical support, and our 30-Day No-Worries returns.

Who This Isn't For: If you never carry passengers, you are paying for an interior channel you will end up switching off. A three-channel setup covers the road ahead, the road behind and the zoom lens without it. The T340 4CH earns its place for rideshare and taxi drivers, and for anyone who wants the cabin on record as well as the road.

Check Before You Order

• The telephoto cable is 1 metre. That camera mounts on the windscreen close to the main unit. It is not a camera you can run to the back of the vehicle.
• Parking mode needs a hardwire kit. The VIOFO HK6-F is the kit built for the T330 and T340 series, and it is bought separately.
• No memory card is included. Four channels recording at 4K and 2K need a card, and a large one.
• There is no screen. Setup and playback happen in the VIOFO app over Wi-Fi.
• The rear camera is not waterproof. It mounts inside the vehicle on the rear glass.

DCG Highlights

What We Love

• A 4x optical zoom telephoto camera on a Sony STARVIS 2 IMX675 sensor, so a number plate several cars ahead stays readable instead of dissolving into the wide shot
• Three Sony STARVIS 2 sensors with HDR running on all four channels, which holds detail when oncoming headlights hit the lens at night
• A 210 degree fisheye cabin camera with four infrared LEDs built into the main unit, so the interior and both side windows are recorded in the dark without a visible light in anyone's face
• Wi-Fi 6 across both 2.4 GHz and 5 GHz, which pulls a 4K clip onto your phone in a fraction of the time an older camera takes
• Five parking modes including hybrid recording, so you decide where the line sits between coverage and battery draw
• All four channels merge into a single video file, which means an insurer receives one attachment rather than four clips to line up
• A screenless body with a tamper-resistant cover over the ports, so there is nothing glowing in your eyeline and nothing that unplugs with a tug
• Quad-mode satellite positioning across GPS, BeiDou, Galileo and GLONASS, stamping speed and location onto every clip

Good to Know

• Parking mode of any kind needs the VIOFO HK6-F hardwire kit, bought separately. Cut-off voltage protection and Bluetooth battery monitoring come from that kit as well.
• No microSD card ships in the box. The camera accepts a card up to 512 GB.
• Voice control recognises English, Mandarin, Russian and Japanese only.
• The front camera records 4K at 30 fps. If you want 4K at 60 fps from a VIOFO, that is the A329S family rather than this one.

Why a Telephoto Channel Reads Plates a Wide Lens Cannot

A dash cam lens is a compromise you make once, at the moment you choose the camera. A 140 degree front lens takes in four lanes and both verges, which is exactly what you want when something happens beside you rather than directly ahead. The cost of that width is resolution per degree. Spread 8 megapixels across 140 degrees and a number plate at twenty metres lands on too few pixels to resolve, however good the sensor behind it happens to be. The telephoto channel removes that compromise by refusing to share the lens. Its 35 degree field of view puts a similar class of sensor on a much narrower slice of road, so the pixels land where the plate is. You are not zooming into footage afterwards, which never recovers detail that was never recorded. You are capturing a second, tighter view at the same moment. The trade-off is honest enough: the telephoto camera sees a narrow corridor and nothing either side of it, which is precisely why it runs alongside the wide front camera instead of replacing it.

How the T340 4CH Compares to the Three-Channel Models

The T340 4CH is the only one of the three that records the zoom lens and the cabin at the same time. If you need a waterproof rear camera for a ute tray or a canopy, the waterproof models are the better fit and the cabin channel is what you give up.

Top Benefits

• Plates you can actually read: the 4x optical zoom telephoto camera holds a number plate at distance that the wide front lens loses.
• Evidence after dark: three Sony STARVIS 2 sensors with HDR on every channel keep detail when the light is working against you.
• Passengers on record: the 210 degree infrared cabin camera covers the full interior and both side windows without a visible light.
• One file, one upload: all four channels merge into a single video, so a claim goes off as one attachment.
• Quicker than pulling the card: Wi-Fi 6 on 5 GHz moves 4K clips to your phone without touching the memory card.
• Parked cover you control: five parking modes let you trade recording detail against battery draw instead of accepting one fixed setting.
• Nothing in your eyeline: the screenless body sits behind the mirror and the tamper cover keeps the plugs where you put them.

How It Installs

1. Mount the main unit on the windscreen behind the rear-view mirror, using the supplied static sticker and adhesive bracket. The built-in cabin camera aims into the interior from here, so position decides the cabin view as well as the road view.
2. Mount the telephoto camera on the windscreen within 1 metre of the main unit, since that is the cable length supplied, and aim it down the centre of the road ahead.
3. Run the 6 metre rear cable along the headlining and down the pillar to the rear glass. This is where trim removal comes in, and the supplied trim tool is for exactly that.
4. Power the camera from the supplied 3.5 metre car charger, or fit the VIOFO HK6-F hardwire kit to the fuse box if you want parking mode.
5. Connect to the camera in the VIOFO app over Wi-Fi to set resolution, parking mode and the GPS zones.

Budget two to three hours for a tidy first install with the cables hidden. We do not install cameras ourselves, but you can find someone local in our directory of independent installers. They are independent businesses, so you book and contract directly with them.

Precise Tracking, Powerful Evidence. From city drives to cross-country trips, the T340 keeps every mile documented. Quad-mode satellite coverage (GPS, BeiDou, Galileo, and GLONASS) provides clear, reliable records of your speed, location, and timestamps on every video playback.

Parking Mode: 24/7 Peace of Mind

Note: to use parking mode, a VIOFO HK6-F hardwire kit is required and sold separately. Cut-off voltage is only available with the VIOFO HK6-F hardwire kit.

• Capture More, Consume Less. Hybrid parking starts in time-lapse, low-bitrate or event-detection recording, then switches to impact detection once your set cut-off time or battery voltage is reached.
• Ultra-Low Draw, Instant Guard. Very low power draw makes this mode ideal for long parking sessions. The T340 waits in standby with impact detection always on, waking within 2 seconds to record a one-minute clip.
• Time-lapse Recording. Capture footage without audio at optional frame rates of 1 / 2 / 3 / 5 / 10 fps to conserve storage space and power. With Super Night Vision, the time-lapse footage is brighter and clearer, even in near-total darkness.
• Low Bitrate Recording. Records continuously at a reduced bitrate to extend recording time and save storage while parked.
• Auto Event Detection. Detects motion and impacts around your parked car, automatically saving the moments before and after each event.

Set Zones, Save Power. Define trusted locations, your home garage or workplace, and the T340 shuts down there instead of entering parking mode. Enable Low Power Impact Recording to keep impact detection on inside those zones.

If voltage ever drops below the level set on the hardwire kit's cutoff switch, power is cut entirely to protect the battery. With removable input and output cables and simple plug-in connections, installation, maintenance, and future upgrades are easier than ever.

Check your car battery's real-time voltage in the VIOFO Dashcam App via Bluetooth, anytime.

Longer Parking, Zero Battery Drain

Pair with the VIOFO BP100 or BP60 battery pack (sold separately) and parking mode runs on the battery pack's own power, for hours longer, with your vehicle battery untouched. Smart Bluetooth features keep the battery level in view: in the app and on the footage itself.

Connected to the battery pack, the dash cam reads its level wirelessly and ends parking recording at the reserve you choose (5% / 8% / 10% / 15%). The reserve keeps impact detection armed, so the camera can still wake and record if the car is hit.

Check the battery pack level on the app home screen, even while the dash cam is off. The dashboard adds charging status, temperature, input and output readings, and the estimated remaining runtime.

Enable the Battery Pack Capacity stamp and every clip records the remaining battery level at the moment of recording, useful context when reviewing a parking incident days later.

Press It, Protect It

One touch is all it takes. Alongside automatic G-sensor impact locking, the side button lets you instantly secure key moments whenever you want. Footage of road incidents, hit-and-runs, or close calls won't be overwritten easily.

Cleaner Installation, Better Protection

Anti-Tamper Design. Protect your dash cam from unauthorized access. The tamper-resistant cover prevents unauthorized tampering or accidental disconnections while maintaining a clean, professional install.

Slim Design, Neat Installation. Easily tuck the ultra-slim coaxial cables behind car panels for a clean, hidden install. Get high-speed and interference-free performance that keeps your electronics running smoothly.

Two Ports, Double Convenience. Charge two devices at once. Featuring a 30W Type-C fast-charging port and a 15W dash cam port, this car charger includes a soft-glow ring for quick, easy plugging at night. Do NOT connect your dash cam to the orange port. It will not power your dash cam.

No Glare, No Reflections. Cut through glare with ease. The snap-on magnetic front and optional telephoto and rear CPL filters reduce windshield reflections and road glare, delivering clear and natural-looking footage.

One Press, Safety Access. Stick the Bluetooth remote anywhere convenient to secure critical footage in one press and configure the side buttons to access your favorite features instantly. Control range: up to 5 meters.

Built to Record, Made to Last. Don't risk dropped frames or missing evidence. Built for constant dash cam recording, VIOFO industrial-grade microSD cards ensure smooth, error-free storage on every journey. For optimal performance, we recommend using a VIOFO microSD card.
