What does time-lapse recording mean on a dash cam?
2 Answers
Time-lapse recording on a dash cam refers to converting a slow-motion long video into a fast-motion short video, similar to fast-forward playback in movies. Here are some related details about time-lapse recording on dash cams: 1. Introduction: It transforms slow-motion long videos into fast-motion short videos, akin to fast-forward playback in movies. The dash cam offers compression ratio settings like 30x, 60x, and 120x. For example, selecting 30x means that after enabling this function, a 30-minute recording will be presented as a 1-minute video. 2. Benefits: It ensures the completeness of the recorded content while significantly saving memory space. Typically, recording for 24 hours only requires about 5GB of memory space, enabling all-day vehicle monitoring and protection to some extent.
I have been driving for many years, and the time-lapse recording feature of my dash cam has been a great help. It means the camera records video in slow motion, capturing a frame every few seconds or minutes instead of continuous recording. This allows for long-term monitoring of the surroundings when the vehicle is parked, preventing theft or minor collisions while significantly saving memory space and battery life. The advantage is that it can record for longer periods without frequent memory card changes, but the downside is that moving images may appear blurry, potentially missing crucial details. I recommend enabling this mode in parking lots or quiet areas, combined with motion detection for better results, ensuring both safety and practicality in recording.
