Buying Guide
Storage Capacity and Endurance
Security cameras generate continuous video streams. A 128GB card can store days of footage at 1080p, while 256GB offers more buffer for high-motion areas. Both cards support Full HD video recording, which is standard for most home security cameras. Look for cards with a V10 rating, ensuring sustained write speeds for smooth recording.
Higher capacity cards reduce the need for frequent overwrites, extending the card’s lifespan. If your camera supports it, 256GB provides a comfortable margin for extended recording without manual deletion. For portable storage alternatives, see our review of the Sandisk 2TB Extreme Portable SSD.
Read and Write Speeds
Fast read speeds, up to 195MB/s on these cards, matter when you need to review footage quickly. With the right reader, you can offload hours of video in minutes. Write speeds must be consistent to avoid dropped frames. The U1 and C10 classes guarantee minimum write speeds of 10MB/s, suitable for Full HD recording.
For cameras with higher resolution or multiple streams, consider cards with higher write speeds. Both models here meet the baseline, but the 256GB version offers slightly better headroom. Explore our top external SSDs on Amazon for even faster data transfer.
Video Class and App Performance
The V10 rating ensures the card can handle Full HD video recording without interruptions. These cards also feature A1 or A5 ratings, which optimize app loading and performance if your camera has smart features. A higher app class means quicker access to recorded clips and smoother live view.
For cameras that double as smart hubs, this performance boost is noticeable. Always match the card’s class to your camera’s requirements. For more electronics recommendations, visit our Electronics category page.
Final Thoughts
For most home security setups, the SANDISK 128GB Ultra microSD UHS-I Card offers a reliable balance of capacity and cost, handling days of Full HD footage with ease. If you need extra storage for high-traffic areas or longer retention periods, the SANDISK 256GB Ultra microSD UHS-I Card provides the headroom to record continuously without worry. Both cards deliver the speed and durability your security camera demands.

Frequently Asked Questions
Can I use any microSD card in a security camera?
Not all microSD cards are suitable. Security cameras require cards with a Video Speed Class (V10 or higher) to handle continuous recording. The Sandisk Ultra cards reviewed here meet that standard. For car-related storage, see our top tire pressure gauges.
How much storage do I need for a security camera in 2026?
A 128GB card stores roughly 7 to 10 days of continuous 1080p footage. A 256GB card doubles that, offering up to three weeks. Choose based on your recording needs and how often you review footage.
Will a faster microSD card improve my camera’s performance?
Faster read speeds help when transferring footage to a computer, but write speeds matter most for recording. The Sandisk Ultra cards provide sufficient write speeds for Full HD. For emergency gear, check our best emergency flashlights for your car.
Can I use a microSD card in an outdoor security camera?
Yes, as long as the camera is rated for outdoor use. The microSD card itself is housed inside the camera, so it is protected from weather. Always check your camera’s operating temperature range.
