Loop recording on a Dash Cam allows for continuous recording, even if the SD memory card is full. This means older files are overwritten automatically, and then there's space for a new file once the SD card gets out of storage. The Dash Cam will be recording on a continuous loop and stores the video files in shorter fragments, usually, 3-5 mins when powered on. So it will always be recording and confirms that the latest trips are always stored on the SD card.
What's Its Working Principle
As it captures the footage and saves it in many small clips （ typically, you can set it to 1, 3, or 5 minutes), the camera instantly overwrites the earlier recorded flips and then the latest clips get the space.
For example, if you set up the camera to a 5-minute loop recording mode. The camera will store the entire captured video recording into a series of 5-minute video clips with the respective file name. And the latest clip will replace the earliest clip automatically when the cam runs out of storage. Definitely, it will operate loop by loop if there's continuous recording.
Why Loop Recording?
Firstly, Loop recording effectively solves the problem of recording suspension due to limited storage space. The loop recording feature ensures that your limited memory space gets reused by replacing the old files with new ones.
Secondly, as it sorts the file into well-organized and manageable clips instead of one large file, Loop Recording makes the file easy to review, download and transfer.
Overall, the Loop recording mode feature is a solution to the limited memory room. That allows you to have the newest recordings of the last several hours without bothering about storage capacity.
Emergency Mode Of Dash Cam Loop Recording
Many people are also worried that loop recording will overwrite the video of the accident, so it is impossible to use it for evidence.
Exactly, the Loop Recording feature does not damage or overwrite any critical files, like event videos detected by G-Sensor activation or manually locked by the user – the files will be protected separately and safely.
What do you need to do?
As the recording time will be shortened with accumulated protected files, regular SD card formatting is essential. It is generally recommended to format the memory card regularly to avoid problems such as excessive memory card files and card aging that affect the normal loop recording. By formatting the SD card, you can easily delete all files, including any protected files.
