When the dash cam is in working mode, when a collision is detected (such as a sudden braking or collision of a vehicle), it will generate an emergency photo and an emergency-related video, and store them separately. These files will not get deleted by loop cycle function.
● Setting Camera Sensitivity
The higher the sensitivity of the dash cam, the easier it is to trigger photographing; The lower the sensitivity of the dash cam, the less likely it is to trigger photographing.
The default collision sensitivity of the dash cam is "Medium", and it supports the selection of collision sensitivity in seven levels: "High", "Medium-high", "Medium", "Medium-low", "Low", "Off" and "Custom".
