Loop-recording dash cams record continuous, 24/7 footage. This means older footage gets rewritten when the SD card becomes full, allowing the dash cam to continue recording new footage without any interruptions. While this can be a benefit if you’re on top of checking and retrieving your recordings periodically, it can also be a pretty major downside if the dash cam constantly overwrites footage before you have a chance to get to it. The very purpose of a dash cam, in this case, is lost if important footage that can serve as evidence in your favor is overwritten, and you’re left with nothing except videos that you have no use for.
One way around this is by purchasing a loop-recording dash cam that automatically backs up footage to the cloud. This way, the recorded footage is always available for you to check and retrieve in the event of an incident. Alternatively, you can also purchase a dash cam that shares real-time emergency or incident alerts. When you receive an alert, you can immediately lock the recorded footage, which will then keep the dash cam from recording over it.
