Fitting a Dash Cam to an electric or hybrid vehicle

Nextbase Dash Cams can be fitted to most electric or hybrid vehicles if a suitable power supply is available. Each camera includes a 12V cable that plugs into the vehicle’s 12V socket. A Hardwire Kit can be used if the vehicle has an accessible fuse box. Alternatively, an OBD Hardwire Kit plugs into the OBD II port for constant power and Smart Parking. The camera uses minimal power and the hardwire kit cuts power if battery voltage drops below 11.6V. Consult your vehicle manufacturer if unsure.

What is file protection and how does it work?

File protection locks a dash cam recording so it cannot be overwritten when the SD card fills during loop recording. Files can be protected automatically by the G-sensor, by pressing the protect button on the camera, or through apps like MyNextbase Connect or Cam Viewer on Wi-Fi models. Important recordings should be backed up to another device. Some dash cams may overwrite the oldest protected files if the protected folder reaches its storage limit.
