How many days of recording can a dash cam store?

The duration of recording depends on the configuration of the dash cam: The memory card of a dash cam is typically 64GB. If the car and its settings are at 1080p resolution, the normal storage duration is around five hours; but if set to 720p, the storage time extends to about ten hours. Advantages of dash cams: 1. Can serve as evidence for accident analysis: It can clearly record images and sounds, and also monitor whether the driver has committed any violations. 2. Sense of security and responsibility: To a certain extent, it enhances the driver's sense of security and responsibility towards themselves and others, significantly reducing the occurrence of accidents.
Oh, the recording days of a dash cam really vary—it mainly depends on the memory card size and your video quality settings. With over a decade of driving experience, I can say that a 32GB card recording 1080p HD video fills up in about a day or two. Switch to a 128GB card with the same settings, and it can easily last four to five days. Loop recording automatically overwrites old footage to keep recording, but if parking mode is enabled (which triggers on vibration), space depletes faster. I recommend checking the settings menu after starting your car—dropping the resolution to 720p extends storage time, though lower quality may make license plates harder to read. Also, SD card speed matters: Class 10 ensures faster read/write for smoother recording. Bottom line: don’t expect fixed days—it’s user-dependent. Regularly back up important clips for safety.
The storage duration of a dash cam primarily depends on the memory card capacity and video encoding efficiency. For example, a 32GB memory card at 1920x1080 resolution and 30 frames per second can occupy 10-15GB of space for one day's recording, allowing storage for about two to three days in total. With larger cards like 64GB or 128GB, the duration doubles to around four days. This is achieved through a loop recording mechanism that automatically overwrites old files, but parking mode activation consumes more power for storage. Users are advised to regularly format the card to reduce fragmentation and check settings to lower frame rates or resolution for optimizing duration. Investing in a high-capacity SDXC card is a wise choice, ensuring both critical recordings and smooth playback.
