How Far Back Can a Dash Cam Review Recordings?

Dash Cam Review Recordings_58 Auto The duration of recordings a dash cam can review depends on the storage card capacity and recording format. Below are details about dash cams and their operational duration: Introduction to Dash Cams: Utilizing the vehicle's engine for operation, dash cams record the external surroundings using high-definition cameras. Operational Duration of Dash Cams: Typically, a 32GB storage card can continuously record for about 8 hours in HD mode. Dash cam SD cards usually come in capacities ranging from 2GB, 4GB, 8GB, 16GB, to 32GB. For larger video storage needs, mobile digital hard drives with capacities of 250GB, 500GB, or even 1000GB can be used. However, most dash cams operate on a loop recording system, where the oldest recordings are automatically deleted once the storage is full to continue recording. Therefore, there is no fixed number of days for how far back a dash cam can review recordings. For example, if within an 8GB memory, the dash cam contains recordings from 10 days ago, then those can be reviewed. But if daily recordings are extensive, footage from 10 days prior might be overwritten.
How long a dash cam can store video mainly depends on the size of your memory card and video settings. For example, my car uses a 128G card set at 1080p resolution, which can store about 10 hours of footage. A 32G card can only record around 3 hours. Remember to use a high-speed card, otherwise, recording in 4K may lag. The key is to enable loop recording, which automatically overwrites the oldest footage when the memory is full. If important footage is overwritten, the dash cam will automatically lock that segment during emergencies to prevent deletion, but for regular recordings, you can only search in reverse chronological order, making it difficult to find footage from a week ago. It's safest to export important recordings monthly for backup.
