What SD card do I need for this dash cam?

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.

Does this dash cam record while the car is parked?

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.

Do I need to hardwire the dash cam?

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.

Will the footage be accepted by my insurer or the police?

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.

Front only or front and rear - which should I choose?

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.

What cameras are included with the T340TW?

The main unit (front and built-in infrared cabin cameras), a telephoto camera and a waterproof rear camera, with their cables, a car charger and a front camera CPL.

Is the T340TW rear camera waterproof?

Yes. The rear camera has a waterproof housing and records in 2K HDR, so it can be mounted outside the vehicle.

What does the telephoto camera do?

It records in 2K with a 4x optical zoom and a 35° field of view, so it captures distant number plates and road events in more detail than the wide-angle front camera.

4K clarity and detail

The front camera records in 4K at 30 fps with HDR. Distant number plates and fast-moving vehicles are captured clearly, providing reliable footage when you need it most.

Cabin and side windows in view

The built-in cabin camera records in 2K with a 210° ultra-wide lens and built-in IR LEDs for day and night coverage. It captures the full cabin and side windows simultaneously — well suited to rideshare drivers and families alike.

Distant details, easily identified

The 2K telephoto camera combines a 4× optical zoom with the ultra-wide front camera to bring distant number plates and road events into clear, usable evidence. A Viofo 512 GB endurance microSD card is recommended to handle the high-bitrate output from all four channels.

All-weather rear protection

The waterproof rear camera records in 2K HDR and is designed for external mounting. Its weatherproof housing handles harsh conditions, ensuring solid evidence against tailgating and rear-end incidents regardless of the weather.
