What size memory card is generally used for a dash cam?

Generally, a 64GB memory card is used for a dash cam. The required memory capacity depends on the duration of each drive, the maximum memory capacity supported by the dash cam, and the resolution of the recorded video. Longer driving times require larger memory, and similarly, higher resolution videos occupy more memory space. A dash cam is an instrument that records images, sounds, and related information during vehicle travel. After installation, it can capture the entire driving process in video and audio, providing evidence in case of traffic accidents. It can also serve as a parking monitor. The video footage from a dash cam should not be edited, as tampering with the data may render it useless in proving liability during accidents. This also helps prevent unavoidable fraudulent claims prevalent in society today. Different dash cam models may vary in appearance, but they generally consist of essential components: a main unit, a speed sensor, data analysis software, and an infrared camera, which is crucial for night vision functionality.
The size of the dash cam memory card really depends on personal needs. Having used various capacities for years, here's my take: 32GB is the bare minimum, storing 4-6 hours of 1080P footage - perfect for short commutes. For frequent highway drivers like me, 64GB is ideal, offering 10-12 hours of recording with longer incident backtracking. 4K dash cam users should start with 128GB - high-resolution videos eat space fast. Pro tip: avoid low-speed cards. My colleague cheaped out on a standard card and missed crucial footage - now he only uses U3-grade cards. Honestly, with today's affordable high-capacity cards, going straight for 64GB is the worry-free choice.
