Can a Dash Cam Work Without a Memory Card?

[MacStephen]

A dash cam cannot function without a memory card because the memory card is essential for storing video recordings. Without it, the device cannot record videos. Therefore, if you find that your dash cam is missing a memory card, it is crucial to reinsert one promptly. After all, in the event of a collision or traffic accident, the recorded footage can serve as critical evidence. When purchasing a dash cam, the first thing to consider is its video quality. Most dash cams on the market offer 720p or 1080p resolution. Note that 1080p video files occupy nearly twice the storage space of 720p files. So, if your dash cam records in 1080p, you should opt for a larger memory card. Otherwise, a 4GB card may only store about an hour of footage, which is insufficient—aim for at least two hours of recording time. Generally, an 8GB card is ideal for 1080p recording, while a 4GB card suffices for 720p. In practice, a smaller memory card may suffice for daily use because dash cams typically operate in loop recording mode. This means newer recordings overwrite the oldest footage, freeing up storage space and alleviating concerns about insufficient capacity. If you're worried about important footage being overwritten, you can lock it directly within the dash cam.
