The Viofo T340 4CH records four views at once: 4K ahead, the cabin in infrared, distant plates through a 4x optical zoom lens, and the road behind. The front and cabin cameras share one screenless main unit behind your mirror, so four channels take up about the same windshield space as one camera.
Who it's for
Rideshare and taxi drivers who need the cabin on record, and anyone who has watched dash cam footage where the plate that mattered was just too far away to read. The telephoto camera exists for that second problem: a narrow 35° view with 4x optical zoom, recording alongside the wide front camera rather than instead of it.
The four cameras
-
Front — 4K @ 30fps, Sony STARVIS 2 IMX678, 140°.
-
Cabin — 2K @ 30fps, built into the main unit, 210° fisheye covering the cabin and side windows, with four infrared LEDs for night recording. Uses an OmniVision OS04J10 sensor.
-
Telephoto — 2K @ 30fps, Sony STARVIS 2 IMX675, 4x optical zoom, 35°. Mounts on the windshield beside the main unit.
-
Rear — 2K @ 30fps, Sony STARVIS 2 IMX675, 160°, on a mount that swivels 360°.
Worth knowing
-
HDR runs on two channels at a time — the front camera plus one other of your choice (cabin, telephoto or rear).
-
No screen — set-up and playback are through the Viofo app over Wi-Fi 6.
-
Multiplex video can merge all four views into one synchronized file, which is the easiest thing to hand an insurer.
-
Supercapacitor, no battery, and a tamper-resistant cover over the ports and memory card.
Parking mode: what you need
The T340 needs the Viofo HK6-F hardwire kit for parking mode — not the HK6, which is for the A329S. It enables Hybrid Parking Recording and a voltage cut-off that protects your car battery. With four cameras drawing power, a Viofo BP100 battery pack is also worth considering if the car sits for long stretches.

Frequently asked questions
How is the T340 different from the T330?
The T340's cabin camera is built into the main unit, so there's no separate interior camera to mount. The T330 3CH uses a separate fisheye cabin camera instead.
Does the cabin camera work at night?
Yes. Four infrared LEDs light the cabin without visible light, so passengers are recorded clearly in the dark.
Why record with a telephoto as well as a 4K front camera?
A wide lens covers the whole road but makes distant plates small. The telephoto magnifies a narrow area ahead, so a plate that is unreadable on the front camera can be read on the telephoto.
