About the Viofo T340WW 4CH
From our tech experts at CEN
The T340WW runs the 4K front camera, an infrared cabin camera and two waterproof external cameras on the T340 platform.
Who it suits
Larger commercial vehicles needing two external views plus the cab: box vans, tippers, HGVs and anything where reversing and side visibility both matter.
Our tech experts advise
Four channels need 512GB high-endurance as a sensible minimum. Add the HK6 USB-C hardwire kit for parking mode. We fit multi-channel systems at our Beeston workshop from £120, with cabling hidden and parking mode configured before you collect. See dash cam installation.

Frequently Asked Questions
Q: What SD card do I need for this dash cam?
A: Use a high-endurance microSD card designed for continuous recording. Standard cards wear out quickly in dash cams. CEN stocks suitable high-endurance cards, and the maximum supported capacity is listed in the Specification tab.
Q: Does this dash cam record while the car is parked?
A: Parking mode is listed in the Specification tab. Where supported, it requires constant power from either a hardwire kit or a dedicated dash cam battery pack, both of which CEN stocks.
Q: Do I need to hardwire the dash cam?
A: Not necessarily. All dash cams work from the 12V socket for drive recording. Hardwiring hides the cabling and enables parking mode, and CEN offers professional hardwire installation from our Nottingham premises.
Q: Will the footage be accepted by my insurer or the police?
A: Dash cam footage is widely used in insurance claims and can be submitted to most UK police forces through their online portals. Recording quality matters, so check the resolution in the Specification tab.
Q: Front only or front and rear - which should I choose?
A: A front camera covers the most common claim scenarios. A two-channel system adds rear coverage for rear-end collisions and tailgating evidence, which is where many disputed claims arise. Three-channel systems add an interior view, suited to taxi and fleet use.
