How Many Days Can a Dash Cam Store Footage?
2 Answers
Dash cams can store footage for up to a week. The number of days a dash cam can retain recordings depends on the capacity of the memory card chosen by the user and the set recording resolution. A dash cam is a device that records images, sounds, and other relevant information during vehicle operation. Once installed, it captures the entire driving process in video and audio, which can serve as evidence in traffic accidents. Dash cams consist of components such as a microprocessor, data storage, real-time clock, display, lens module, operation keys, printer, and data communication interface. They are primarily categorized into portable dash cams and aftermarket in-dash DVD dash cams.
How many days a dash cam can store footage is uncertain—it depends on the size of your memory card and the video quality settings. My car has a 128GB card with 1080P HD recording, which stores about three to four days of footage. If set to 720P standard quality, it can last an extra two days. A crucial point: dash cams now use loop recording, meaning new footage overwrites the oldest, so don’t assume it’ll save forever. Once, I scraped a guardrail at my neighborhood gate and quickly saved that clip to my phone—three days later, the dash cam had already overwritten it. Also, parking surveillance consumes a lot of space; I usually keep it off unless parking in unfamiliar areas. I recommend at least a 64GB card, preferably a high-speed one to avoid missed recordings.
