How Long Does a Dash Camera Store Data?

by Terry Hu on May 24, 2022

A dashcam is a recording device that continuously records footage and as the name suggests it is placed on the dashboard of a car to record in case any accidents happen so you have evidence.

For this piece of technology to be effective, it needs to be constantly recorded for you to be fully sure that if any accidents happen that you are going to get it on camera. This type of car recording device is popular among car owners and is available with a wide range of features. If you are wondering how long a dash camera stores recorded data, you are not alone.  Here, we'll discuss recording resolution, frame rate, and memory. For more detailed information, you can consult with us if you bought a dash cam from Mercylion, we are here to help. A dash camera's recording time depends on several factors, including frame rate, recording resolution, and memory.

 

Memory Options

When it comes to purchasing a dash camera, you'll have several different memory options. SD cards, Micro SD cards,etc.

SD stands for Secure Digital card, which is used to stored files, music, pictures and any other data. SD cards come in different sizes, with capacities ranging from 4GB to 400GB. SDHC and SDXC are two different types of the SD card. They have smaller capacities, and a typical 8GB card is only around 7.4 GB in real-world size. In real-world terms, one minute of 1080P video footage takes up around 100MB, and a 32GB card is enough for a commuter.

While SD cards are the most common memory cards, MicroSD cards are a better choice. MicroSD cards are smaller and more flexible than SD cards. Most dash cams feature a MicroSD card slot. However, full-sized SD cards will not fit into a MicroSD card slot. MicroSD cards have the advantage of being more portable and allowing you to use them with other devices. Also, a dash camera with a MicroSD card slot is compatible with more types of devices than just dash cams.

If you purchase a microSD card for your dashcam, make sure you purchase a card with the right file system that gets one with FAT32. If not, you'll likely have to reformat the memory card. To format an SD card, Windows gives you the option to use three different file systems: NTFS, FAT32, and exFAT. Most micro SD cards come pre-formatted with FAT32, but more advanced models will let you format the memory card yourself. This means you can save your photos and videos to a larger memory. FAT32 is an older file system that’s not as efficient as NTFS and doesn’t support as big a feature set, but does offer greater compatibility with other operating systems. exFAT is a modern replacement for FAT32—and more devices and operating systems support it than NTFS—but it’s not nearly as widespread as FAT32.

Another option for you to consider is buying a second micro SD card. You can purchase a decent one about 15usd-40usd, and if your memory card fails, you'll still have footage. You also don't have to worry about losing footage if you forget to remove the memory card. You can always get a new one later if needed. And don't forget to always remove the memory card from your dash cam after an accident or incident.

If you're looking for a dash cam to improve the security of your vehicle, you can purchase a 32GB micro SD card, it is great for value for those who use their dash cams for driving recording. These cards can record a full day's worth of 1080P video, which is more than enough for most drivers. If you're interested in 4K video, you can get 64GB or 128GB cards. Some dash cams only support a maximum card size of 64GB, so make sure to get the right one for your needs.

For example, Mercylion A10 Dash Camera for Mercedes-Benz SD Card Storage Data Reference

 

Photo Resolution 4G 8G 16G 32G
1920x1080(30fps) 34 min 68 min 136 min 272 min
1280x720(30fps) 40 min 80 min 160 min 320 min

 

SD cards are available in different speed classes. Generally, a dash camera with two channels will write about 16GB/hr, while a dash cam with a single channel will write about 8GB/h. While you can save money by buying a higher-speed card, it will not increase the video quality. You'll have to choose between speed and durability before purchasing a dash camera.

 

Memory Recording Speed

If you're considering purchasing a dash cam, you should consider how fast it records. The speed of recording depends on the memory card it uses and its bit rate. The memory card is where all the footage is stored as data instead of being stored in an in-built storage system like you would find in computers for example.

While most dash cams have a limited amount of memory, a good one will not shut off recording when the memory card is full. Quality dash cams also feature continuous loop recording, meaning that any footage is recorded over the oldest footage. This allows for almost endless video storage. Just make sure to use a high-capacity SD memory card, since recording time in a dash cam is limited, and you'll need more space than you may think!

The bit rate is the amount of footage that a camera is able to record per second. The bit rate is measured in megabits per second. A 25 Megabit camera can record over 500 megabytes per second, but it won't be as fast as a 1 Gigabyte dash cam. The bit rate is also dependent on how high of a resolution that a camera can record, for example, dashboard cameras that can record in 4K resolution will most likely have a much higher bit rate than a dashboard camera that has a maximum resolution quality of 1080p.

The bit rate can also be configured in cameras by tweaking the footage quality when you lower the quality of the footage the bit rate will drop and when you increase the quality the bit rate will also end up increasing.

The speed of dashcams can be inaccurate because of varying distances and obstructions on the road. The distance between your car and the satellite can also cause some errors in the recording. Also, your dashcam's signal needs to be stable. This is because of possible obstructions or other errors in the transmission. If you're concerned about the accuracy of your dashcam's recording, it's a good idea to check the speed before you use it in a court of law.
