For stable use,it is recommended to format the micro SD card regularly. Recommend: Once a
month.

29

Q: Why is every video recording so short?
A: We set the recording interval of each video to 1min/2min/3min.This is for the convenience
of finding the locked video later.The main function of the recorder is to record, especially to
record emergency video. If each video is too long and the G-Sensor triggers emergency
recording when a collision occurs, the video will be locked and cannot be covered by the loop
recording, and customers will be difficult to find the video in the subsequent search. You need
slide the longer progress bar to find this locked video.And the capacity of the Micro SD card is
limited, if the locked video is too long, the normal video capacity that can be stored will
decrease.
(Avaliable after correctly installing the hardwire kit)
Movie Clip Time: 1minutes/2minutes/3minutes
Parking Monitor

turn on and record 30 seconds locked video after a collision is detected.
Lapse rate: 1FPS/2FPS/5FPS
Record a frame every 1/3/5 second.
Lapse time: Off/12Hours/24Hours
After setting the time and rate, the dash cam will turn off the screen but keep recording
time-lapse videos for the next 12/24 Hours.
NOTE:
In the time-lapse recording mode, the car will not trigger the G-Sensor when it is vibrated,
and the emergency recording video will not appear in the locked folder.
31

Principle
When the hardwire kit is correctly connected and the Parking mode lapse Recording mode is
turned on, the acc is out of power when the car is turned off (bat is always charged), and the
dash cam detects that the acc is out of power and will stop normal recording and enter the
"Lapse Recording mode". When the engine is started and the acc is powered, the machine will
boot into the normal recording mode.In the normal recording state, it can record 30FPS, and
time-lapse recording can choose 1FPS, 2FPS, and 5FPS.
Advantage
1. Save electricity, will not drain the car battery.
2. Save the SD card space, which is 1/30 of the normal recording.
