A139 Pro 4K Dashcam – 1 Channel – Front

Viofo cameras require an SD card to store video footage. It's crucial to use a High Endurance micro SD card suitable for dashcams. We recommend Viofo cards. The card size depends on the desired video storage length. Viofo cameras loop record, overwriting the oldest footage when the card is full. Our most popular size is 128GB.

This wireless button can be located in the cockpit of your vehicle. One press will automatically lock the current image/video clip. This file will be located in a protected file and not be overwritten when the camera loop records.

All Viofo Dashcams are provided with a good length USB cable to power your dash camera. However, you may wish to completely hardwire your camera to your vehicle so that the parking mode feature is fully functional. Viofo have 3 variations of Hardwire kit for the different cameras, but select this via the bundle option below and the correct version will be provided for the selected camera.

These are used to connect the hardwire kit to your vehicle via a fuse board. If you are having your camera professionally installed your installer will generally provide these. Viofo provide 4 different types, your car manufacturer or garage will be able to confirm the connection type. If in doubt we do provide a combination pack including all 4 variations.
