When setting up a dash cam, one of the most important decisions you’ll make is choosing the right memory card. Dash cams continuously record footage, and the size of the SD card directly affects how much video can be stored before old files are overwritten. A 32GB micro SD card for dash cam is a popular choice, but is it the right one for you? Let’s break it down.
32GB Micro SD Card for Dash Cam
Why Do Dash Cams Need a Micro SD Card?
Dash cams don’t usually come with built-in storage. Instead, they rely on micro SD cards to record and store video footage. These cards capture everything from short trips to long drives, including critical events like accidents.
The card you choose should handle constant recording, looping, and sometimes extreme temperatures inside a car. That’s why it’s important to pick the right micro SD card for dash cam use.
How Long Does a 32GB Micro SD Card Record in a Dash Cam?
The recording time depends on your dash cam’s resolution and settings:
- 1080p Full HD (standard): Around 4–6 hours of continuous recording.
- 1440p (2K): Around 3–4 hours of continuous recording.
- 2160p (4K): Around 2–3 hours of continuous recording.
Once the card is full, the dash cam will start overwriting old footage in a loop. For most daily drivers, a 32GB card is enough to cover a typical commute, but it may not hold multi-day road trip footage without overwriting.
Is 32GB Enough for a Dash Cam?
A 32GB micro SD card for dash cam can be enough if:
- You mainly drive short trips or commutes.
- You don’t need to save days of continuous footage.
- You regularly back up important clips.
However, if you often go on long drives, use 4K recording, or want to store multiple days of footage before overwriting, you may want to consider 64GB, 128GB, or even 256GB cards (if your dash cam supports them).
Best Types of 32GB Micro SD Cards for Dash Cams
Not all SD cards are built the same. Dash cams require high-endurance micro SD cards because of constant reading and writing. Look for:
- Class 10 or UHS-I/U3 rating for smooth video recording.
- High Endurance or Pro Endurance models designed for surveillance and dash cam use.
- Temperature resistance to handle hot summers and cold winters inside a car.
Popular brands include SanDisk High Endurance, Samsung PRO Endurance, Kingston Endurance, and Transcend High Endurance.
Tips to Make Your 32GB Micro SD Card Last Longer
- Format regularly (once a month) inside the dash cam.
- Avoid cheap, unbranded cards that may fail quickly.
- Check compatibility with your dash cam before purchase.
- Replace every 12–24 months, as micro SD cards wear out over time.
