What does time-lapse recording mean in a dash cam?
2 Answers
Time-lapse photography, also known as interval photography or time-lapse recording, is a shooting technique that compresses time. Here is some relevant information about time-lapse photography: 1. Function: A dash cam with time-lapse recording function will adopt a one-frame-per-second recording method during parking surveillance. Every 30 minutes of footage is compressed into 1 minute for storage. This not only ensures the integrity of the recorded content but also significantly saves memory space. Generally, recording for 24 hours only requires about 5GB of memory space, enabling all-day vehicle monitoring protection to a certain extent. 2. Definition: Time-lapse photography, also called interval photography or time-lapse recording, is a photographic technique where the frame capture rate is set much lower than the frequency required for normal continuous viewing. When played back at normal speed, it creates a sense of time passing quickly, producing a feeling of time elapse.
Time-lapse recording in a dash cam is a special low-speed recording mode. Having driven many cars, I find it extremely practical. Primarily used when parked, it captures a frame every few seconds instead of the usual 30 frames per second in normal recording. The benefits are obvious: it saves memory card space—a small card can record a whole day's events, like overnight parking surveillance; it conserves battery, especially for dash cams relying on built-in batteries, extending usage by half a day; and it's highly practical—compressed footage is concise and easy to review for parking lot incidents, like scratches or theft attempts. I often use it during commutes, paired with motion detection, for greater efficiency. Setting it up is simple, just a one-touch option in the menu. Once, it helped a friend record an entire accident, proving this feature is worth keeping on.
