How Many Days of Footage Can a Dash Cam Store?
2 Answers
Dash cams operate in a loop recording mode. The number of days of footage a dash cam can store depends on the size of the memory card inside the dash cam. The specific durations are as follows: 1. 16G card: If recording 1080P content, the duration is approximately 100 minutes. 2. 32G card: If recording 1080P content, the duration is approximately 200 minutes. 3. 4G card: If recording 1080P content, the duration is approximately 400 minutes. Relevant information about dash cams is as follows: 1. Dash cam: An instrument that starts recording as soon as the engine is turned on, capturing images and sounds during the vehicle's journey. 2. Purpose: To record the entire process of the car's journey in video and audio, which can serve as evidence in traffic accidents, functioning similarly to a 'black box'.
I've been using a dash cam for several years and know that how many days of footage it can store mainly depends on your memory card size and settings. My car is equipped with a 64GB card, which can store about two days of footage when recording in 1080p, because the dash cam automatically loops and overwrites old files to free up space. If you lower the resolution or switch to 720p, the storage time can extend to over three days. I suggest beginners not skimp on this expense and directly opt for a high-capacity card like 128GB, so accident footage isn't overwritten too quickly. As a daily habit, I plug it into my computer every weekend to check and save important clips, just in case evidence is lost in an accident. A card with too little capacity fills up easily, which can affect safety recording at critical moments.
