4K + 2K + 2K + 2K recording
T340 4CH Dash cam with 4K + 2K + 2K + 2K HDR recording, built-in IR cabin camera, 4x optical zoom telephoto camera, Sony STARVIS 2, Wi-Fi 6 and GPS.
The T340 4CH records four perspectives at the same time: true 4K ahead, 2K telephoto for distant detail, 2K infrared inside the cabin and 2K behind. Wide context and close-range evidence, captured together.
The wide 4K front view captures the scene. A separate 4× telephoto camera gets closer to distant detail. Cabin and rear cameras complete the record, while STARVIS 2 and HDR help when the light gets difficult.
Tap each camera to see why the T340 uses a dedicated lens for each part of the drive.
The front camera records the full road scene in 4K at 30 fps with HDR, capturing the context around an incident as well as fine detail within the frame.
The T340 is unusual because it records both at once. The front camera keeps the full road scene in frame, while the telephoto camera concentrates on the part that is usually too far away.
The front camera builds the scene: lanes, positioning, traffic flow and the wider context around an incident. The telephoto lens narrows the field of view and applies genuine optical zoom, so distant number plates and vehicles appear larger in frame without relying on a digital crop.
The front camera handles the main road view and captures the broad context of the drive ahead.
Three Sony STARVIS 2 sensors are paired with HDR across multiple channels to manage high-contrast scenes. Headlights, backlighting and dark roads are handled with more balanced exposure, helping number plates and surrounding detail remain easier to read.
The dedicated 2K telephoto camera concentrates on a narrower 35° field of view. Its optical zoom makes distant vehicles and number plates larger in frame without digitally enlarging the image, while the 4K front camera keeps the wider scene.
The 2K cabin camera covers far more than the front seats. Its 210° fisheye view reaches across the cabin and side windows, while four infrared LEDs support recording when the interior is dark.
Scroll through the sequence. As each step comes into view, the visual on the left updates to show the part of the system doing the work.
The 4K front camera establishes the full scene ahead.
When an event happens, context matters first. The main front camera records the road ahead in true 4K and keeps the whole situation readable.
The telephoto camera does not replace the front camera. It adds a second, more focused record for the parts of the road that are too far away for a wide lens to show well enough.
For rideshare, family driving or any situation where the inside of the car matters, the cabin camera extends the record beyond the windscreen.
Rear-end incidents and tailgating are captured on their own channel, making the T340 a genuinely four-direction system rather than just a front camera with add-ons.
Dual-band 2.4 GHz and 5 GHz Wi-Fi 6 makes live view, settings changes and video transfers in the VIOFO app faster and more stable.
Supported voice commands let you lock footage or take a snapshot without reaching for the camera. Spoken alerts can also flag key status changes and errors.
GPS, BeiDou, Galileo and GLONASS record location, speed and timestamps alongside footage, adding useful context when a clip needs to be reviewed.
Combine two, three or four camera feeds into one file for quicker multi-angle review, export and sharing without editing the feeds together first.
Watch the official T340 overview for a closer look at the four-camera setup, image quality and the features that make the system different from a conventional front-and-rear dash cam.
Hybrid Parking Recording can begin in time-lapse, low-bitrate or event-detection mode, then switch to low-power impact detection after a set time or voltage threshold. Smart geofencing can keep parking mode off at trusted locations.
Pair the T340 with a compatible VIOFO BP100 or BP60 battery pack, sold separately, and parking recording can run from the battery pack instead of the vehicle battery. Supported Bluetooth features can display battery information in the app and on recorded footage.
Slim cabling, secure covers and practical controls help keep the finished installation tidy and easy to live with.
Alongside automatic G-sensor locking, the side button lets you manually secure an important clip before normal loop recording can overwrite it.
Ultra-slim coaxial cabling is easier to route behind trim, while the tamper-resistant cover helps protect key connections from accidental or unwanted disconnection.
The magnetic front CPL is included to reduce windscreen reflections. Optional CPL filters and the Bluetooth remote let you tailor the rest of the installation.

It is a four-camera, three-piece system. The main unit contains the 4K front camera and built-in 2K infrared cabin camera. A separate 2K telephoto camera with 4× optical zoom and a separate 2K rear camera complete the system.
The front camera records at 4K 30fps, while the cabin, telephoto and rear cameras record at 2K 30fps. During recording, HDR can be enabled on the front camera and one additional camera channel at the same time.
The T340 supports Hybrid Parking Recording, Low Power Impact Detection, Auto Event Detection, Time-lapse Recording and Low Bitrate Recording. Hybrid Parking can begin in time-lapse, low-bitrate or event-detection mode before switching to low-power impact detection after the selected time or battery-voltage threshold is reached.
Not for normal driving. The included car charger is sufficient while the vehicle is running. The HK6-F hardwire kit is required if you want the camera to use the vehicle's fuse box for parking mode and battery-voltage cut-off protection. Alternatively, a compatible VIOFO BP100 or BP60 battery pack can power parking recording without drawing from the vehicle battery.
Built-in Wi-Fi 6 supports both 2.4GHz and 5GHz connections for use with the VIOFO app.
The T340 supports microSD cards up to 512GB. The card is sold separately. For continuous dash-cam recording, VIOFO recommends a high-endurance card designed for sustained video recording.
The front camera includes a magnetic CPL-700. An optional CPL-600 can be fitted to the telephoto and rear cameras; the built-in cabin camera does not require one. Bluetooth is built in, so the optional BTR200 remote can be added for one-press footage locking and configurable shortcut controls.
