A 4K dash cam is a windscreen-mounted camera which records a driver’s journey in ultra HD. The Nextbase 612GW 4K dash cam is the first of its kind to offer Ultra HD 4K resolution, recording at a resolution of 3840 x 2160.

What are the benefits of a 4K dash cam?

In comparison to other HD models, a 4K dash cam can capture higher quality images and clear-cut recordings of vehicle license plates. This is especially useful when providing recordings as evidence in the event of a road incident of accident.

Other benefits include:

  • Improved contrast and colour range
  • Clearly zoom on road signs and number plates further away
  • Greater ability to record passenger & driver details, especially useful if you’re involved in an accident with a driver using a mobile phone

How long can a 4K dash cam record?

The maximum recording time on a 4K dash cam is 200 minutes. This time is based on an MP4 recording using a 64GB+ U3 class SD Card. You could use for a 128GB SD card which will provide 400 minutes of recording. The maximum recording loop time when using a 64GB U3 class MircoSD is 4 hours, but then you needn’t worry as the dash cam will continue to record all the time and automatically “lock” any incident files.

A Nextbase 612GW 4K Dash Cam requires a minimum 64GB U3 class MircoSD card due to the large data rate generated by 4K recordings.

What’s the battery life of a 4K dash cam?

Whilst the dash cams are designed to be powered in the car there is an internal battery. The 612GW 4K dash cam runs for approximately 15-20 minutes without 12V power. The battery design allows the ‘Auto Power Off’ feature to function in event of power loss within the vehicle.
