SQ8 Mini DV Camera is a really small and good dashcam. It weights just 25g and can record 1080p @ 15fps videos, and is as small as a coin.
An understandable video on youtube explains how this small camara works. Just google SQ8 manual. (https://youtu.be/vANF8SU6Ods)
To set the date right:
Connect camera to computer
Create a file TIMERSET.txt on the root-folder of the microsd card.
type 1 line with format YYYYMMDDHHMMSS ie. 20160629192500
Disconnect the camera from computer.
Turn it on.
The time is now set and the TIMERSET.txt file is deleted.
