Why is G840S dash cam every video recording so short?

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.
