A 32GB memory card for a dash cam can record for approximately nine hours. Here is some extended information about dash cams: 1. Introduction: A dash cam is a digital electronic recording device that records and stores information such as vehicle speed, time, mileage, and other driving-related statuses, and can output data through interfaces. 2. Main Components: The main unit, which includes a microprocessor, data storage, real-time clock, display, operation keys, printer, data communication interface, and other devices; speed sensor; data analysis software. 3. Main Functions: Self-check function; identity recognition function; recording and storage of driving time, speed, and mileage; overspeed alarm and recording function; fatigue driving reminder function; accident suspicious point recording and analysis function; data communication function.

I've driven for many years and used several dash cams. How long a 32GB memory card can record mainly depends on the video quality you set. If set to 1080p HD with a bitrate around 10Mbps, it takes about 75MB of space per minute. A 32GB card has 32768MB of space, so it can record for about 5 to 6 hours. But in reality, it lasts longer because different dash cams have varying compression efficiency; for example, some night modes take up more space, while daytime modes use less. It's advisable not to use the highest quality setting—choosing 720p can extend recording to around 10 hours, which is sufficient for daily commutes. Also, pay attention to the card's quality; opt for brands like Samsung or SanDisk to avoid read/write errors that could interrupt recording.

I drive for Didi every day, and the dash cam is my great assistant. I've used a 32G card, which can record about 4 to 5 hours at 1080p before it automatically overwrites—the loop recording feature is a big help, so I don't have to worry about running out of space. However, the duration is a bit short, especially on long trips, and you might find it insufficient to cover the entire journey. From my personal experience, reducing the resolution or turning off the parking monitoring feature can extend the recording time. Also, the card should be formatted to FAT32; otherwise, it's prone to issues. I recommend buying a high-speed card for faster read and write speeds to avoid missing crucial footage.

I have a 30-minute commute to work every day, and a 32GB card in the dashcam isn't a big issue. At 720p, it can record for over 10 hours, which is enough to cover the workday. The key is to lower the video quality in the settings, such as choosing a medium compression level, to save space. Loop recording automatically overwrites old files, ensuring no interruptions. From a practicality perspective, a 32GB card is cost-effective, but I don't recommend using low-quality branded cards as they are prone to failure. If you drive more at night, it will consume more space, so I suggest enabling power-saving mode during the day. Overall, with proper settings, it can be used efficiently.

As an experienced driver, safety is the top priority. A 32GB memory card recording for about 5 hours isn't considered long, but the dashcam's loop recording feature prevents it from stopping when full. In case of accidents or long journeys, the space might not cover the entire trip, increasing risks. It's recommended to lower the video quality or opt for a larger card like 64GB to extend recording time. Regularly clean the card and format it with the appropriate file system to avoid recording interruptions. From experience, investing in a good card is crucial to ensure recordings aren't lost in case of disputes.
