How To Choose The Best Micro SD Card For Your Eufy Camera?

If you have a Eufy camera or plan to purchase one for your home security, you’ll need an SD card to store video footage. The Eufy cameras support micro-SD cards with up to 128GB of storage, which means there are many options to choose from. 

However, there are certain features regarding micro-SD cards that you must consider before buying one for your security camera. This article will cover those features and details to help you choose the best micro-SD card based on your unique needs.

Best Micro SD Card For Your Eufy Camera: Buying Guide

Make your buying decision based on the following features if you want to choose the best Micro SD card for your Eufy camera.

Storage Space

Micro-SD cards come in different sizes in terms of storage space. Like most surveillance cameras, you can use micro-SD cards with up to 128GB of storage space with your Eufy Camera. However, it’s advisable to double-check the specifications of your device to determine the right storage size.

Choosing the largest compatible size will allow your camera to record videos for far longer, and you won’t need to switch micro-SD cards frequently. It’s especially true if your Eufy camera can record high-definition videos continuously. But if you have a security camera that records videos in clips by detecting the motion in the frame, you can go with a micro-SD card with smaller storage space.

Read and Write Speed

The write speed of a micro-SD card means how fast it can save video files. On the other hand, the read speed refers to your card’s time to open or transfer camera footage to a connected laptop or computer.

Your surveillance camera footage can be multiple hours long, making your video file very large. In addition, if you have a slow micro-SD card, it’ll take a lot of time to write and read the footage.

Currently, the UHS-2 micro-SD cards are the fastest ones available in the market, but they’re quite expensive. They’re based on high-speed data transmission protocol. You can purchase an SD card with UHS-2 specifications if your budget allows.

The second option is UHS-1, which is more suitable and budget-friendly. It’s also based on the high-speed data transmission format, but it is more affordable than UHS-2.

Note: UHS-1 offers speeds up to 104 MB per second, and USH-1 offers up to 312 MB per second.


The brand and model of a micro-SD card do matter. We recommend you purchase an SD card offered by a reputable brand because such products usually come with a long-term warranty. These products protect your investment, but they also provide better architecture and quality support.

All the brands and products mentioned in this article are well-known. But, better yet, Eufy also recommends its customer buy SD cards offered by the manufacturers we have selected.
