How long can a 32GB dash cam record?

This depends on the device specifications, not just the memory card size. Dash cams have a loop recording feature. With 32GB storage, it can record about 6 hours for 1080P front and rear recording. An 8GB card can record approximately 2 hours at 720P resolution, while 32GB can store 7-8 hours of 720P footage. For single-lens dash cams, it can record around 12 hours. Usage precautions: 1. In winter when temperatures drop, dash cams are designed to work in normal temperature environments. Excessively low temperatures may cause electronic components to operate abnormally and potentially damage them, so avoid recording in extremely cold conditions. For installation position, mount it near the interior rearview mirror for optimal field of view. Ensure the lens is within wiper cleaning range for clear rainy-day recording, and the installation shouldn't interfere with airbag deployment zones.
I previously used a 32GB dash cam and found that recording duration varies significantly, primarily depending on video quality and settings. For instance, in 1080p HD mode, each GB typically stores 1 to 1.5 hours of footage, so 32GB lasts just over 30 hours. However, switching to 720p standard mode extends it to around 40 hours with slightly reduced image quality. The loop recording feature automatically overwrites old files, preventing the card from filling up too quickly, though enabling night vision or motion detection consumes extra storage. For beginners choosing a dash cam, I recommend not just focusing on card capacity but also exploring settings menus to find the optimal balance—longer recording time is convenient, but image quality shouldn’t be overly compromised. Regularly back up critical footage to avoid losing evidence accidentally. In summary, 32GB suffices for daily use, but carrying a spare card is advisable for long trips.
