Shooting wildlife with a trail camera is struggling until you see clear photos and videos. But a compatible and standard-sized SD card is required to store high-quality images and videos. So, what size SD card is needed for a trail camera, and how to find a compatible match?

The SD card size needed for a trail camera depends on the resolution of the camera and the number of pictures/ videos you take. And in many cases, a large SD card size (i.e.,128 GB) is required to store maximum images and movies. Similarly, if you have a certain number of images or video clips, then a 2 GB, 4 GB, or 8 GB SD card would be enough (depending on your needs).

If you are interested in knowing more about the different sizes of SD cards best for trail cameras, keep reading until the end!

Different Sizes of SD Card For Trail Cameras:

For your trail cameras, you can try out the various SD card sizes listed in this section:

2GB to 4GB: These are the smallest SD card size and are suitable for trail cameras that capture a small number of low-resolution pictures and videos.

8GB: This one is considered to be a medium-sized storage device. It pairs well with trail cameras as well. The photo or video Pixels Per Image (PPI) range between low and medium.

16GB to 64 GB: If you’re looking for a larger storage capacity, a 16-64 GB SD card would be the right call. You can click images with all PPI or resolution with this much capacity.

128GB: This is the largest SD card size, and is an optimum pick for the best resolution, speed, and storage without any trouble whatsoever.

Which SD Card Should You Purchase?

Generally, a trail camera uses a 2GB to 32GB SD card to function correctly and store contents. However, some trail cameras are different and are compatible with other SD cards.

For example, if your target is not to focus on image quality or you plan to store fewer images, a 2GB to 16GB SD card would be enough. A 32GB or 64GB SD card would be a good option for higher resolution and keeping a lot of pictures and videos.

The built-in memory storage of a few trail cameras can also affect the size of the SD card. This is because if your trail camera has much more memory storage, you might not require a big SD card.

Hence, it is important to check your trail camera’s storage capacity before purchasing it.
