Loop recording is a feature that makes successive recording possible without having to delete the files by a user. It is a useful feature because a device can automatically replace files by themselves. It works as replacing the oldest files with the new ones. This is why a dash camera can still be able to record even though the memory of a medium has all been used up but the length of the time that a file could stay on a memory is limited and the time varies in accordance with capacity of memory, type of video codec and size of a video file. So, if a user wants to see a specific video on a specific time period, a user should take a conservation time of a file into their consideration because a user might be trying to find a file that’s already has been gone and lost. but most of the dash cam nowadays can conserve files quite a long time, it isn’t a problem as far as a person tries to search for months old files. but it is inevitable that a file will be deleted, so it is wise to know your dash cam’s file conserving time for how long. Let’s find out factors that effects conservation time of a file in a dash camera in just little bit more of details.

 

 

1. Memory Capacity

Memory Capacity is an important piece in terms of preservation of video files in a dash cam. As Memory capacity gets larger the more video a user can save. Typically, in the market dash cam is sold with SD Cards that ranges from 16GB to 512GB. Unlike others, GNET System supports SSD card case in which a user can adapt to enlarge memory capacity up to 1TB. SSD card is sold separately.

 

 

2. Codec

Video Codec also hugely effects recording time. Just 5 years back, most of the dash cam used H.264 but nowadays the trend is changing to adapting H.265. H.265 codec can comprise files twice as much as H.264. Therefore, it saves twice as much videos. So, we recommend to purchase a dash cam with H.265.

 

 

3. Resolution

The higher the resolution bigger the file size is indefinite. In resolution, there are typically categorized into 4 types: HD, FHD, QHD, 4K. HD is 1280*720p, FHD has twice as many pixels as that of HD, QHD has twice as many pixels than FHD and QHD has pixels 4 times as many pixels of QHD. You could say that the clarity of resolution increases as there are more pixels as more colors can be shown.

 

 

4. FPS

FPS is a unit stands for Frames Per Second which directly translated to how many pictures can be captured in a second. 30FPS is generally used and 60FPS is a comparably new technology is slowly taking up its share in the market. As FPS increases, motion captures run smoother but as FPS gets higher, the size of the file gets bigger so in return it effects time of file conservation in a dash cam.

 

Conclusion

In order to maximize the use a user has to take resolution, FPS, memory size, codec into an account. Let’s avoid situation where a user tries to find desired files after it is already gone by knowing conservation time of files.
