Picture Style

Some fascinating accessible attributes are a long exposure, to get excellent nighttime pictures. Manual settings comprise White Balance, EV Exposure Worth correction, ISO (detector sensitivity) and metering. Not all action cams offer such many different settings.

Video Style

A number of the settings I’d like to emphasize are FOV (field of view) which you are able to narrow, movement detection, which begins recording when a movement is found within the picture. Loop record is accessible which saves videos in shorter files and overwrites the earliest. That’s valuable when you use it as a dashboard cam. For that goal, you can even switch on Car DV and Delay away, or so the camera begins when plugged into a power source and turns off when disconnected. Similar to picture style the manual settings comprise White Balance, EV Exposure Value correction, ISO (detector sensitivity) and metering.
