How many days can a dash cam record be stored?

Dash cam recordings can typically be stored for about 3 days to a week. When purchasing a dash cam, pay attention to: 1. The stability of the dash cam is very important. Make sure to avoid purchasing a dash cam that may cause unstable footage due to quality issues; 2. Pixel quality. If the pixel is low, the recorded images may be unclear, making it difficult to identify traffic situations even if they are recorded. A dash cam is an instrument that records images, sounds, and related information during vehicle travel. After installation, it can record the entire driving process in video and audio, providing evidence for traffic accidents.
I'm an experienced driver who has used several dash cams, and the storage duration mainly depends on a few factors. The larger the memory card capacity, the longer the storage days naturally. For example, a 32GB card can store about one and a half to two days of footage at medium resolution; upgrading to 64GB extends it to two to three days. You also need to consider recording quality and the loop recording feature, which automatically overwrites old files to prevent the card from filling up. I recommend regularly checking the card’s status, buying a reliable brand instead of going for cheap options, and upgrading the capacity or backing up important clips when needed—safety comes first.
After driving for so many years, the storage of the dashcam has been a concern for me. A typical 16GB card for home use can only store half a day to a day's worth of footage, and accident videos can easily be overwritten if not careful. I use an APP to monitor the remaining space and usually set it to low-power mode to extend the storage duration. For long trips, I switch to a 64GB card, which can store up to three more days of footage without issues. The key is to develop a habit of clearing the card every two weeks to ensure the system's automatic overwrite mechanism functions properly, so I don't find the recordings missing when I need them.
As a newbie in the car enthusiast world, I've found that storage days are limited by the memory card size. A standard 32GB card stores footage for 1-2 days under normal settings, but drops to half a day with HD recording. I recommend purchasing a dash cam with loop recording—its overwrite mechanism effectively extends usage time. I always keep dual cards for switching. Small-capacity cards with good cost-performance aren't expensive, but larger ones like 128GB save frequent swaps—just monitor file occupancy rate and regular cleanup frequency.
