A reliable SD card is crucial for effective camera trapping.

In this guide, we’ll cover how to select a card, maintain it, and fix common issues if they arise.

Choosing the Right Card

When selecting an SD card for your trail camera, consider both your specific needs & the card’s compatibility with your camera model.

First, ensure the card capacity matches your camera’s requirements. Different models support varying maximum sizes, ranging from 16GB to 512GB. To be sure, check the manufacturer’s manual or the product specifications listed on our website.

For most users, a 32GB or 64GB SD card will be enough, especially for watching wildlife in the garden. However, if you plan to leave the camera in a remote spot for a month or longer, a 64GB card would be ideal. For even longer periods, a 128GB card might be better.

Speed Class

The read & write speeds of SD cards can get confusing. These speeds are important because they determine how quickly data is read or written. The write speed is key for recording high-res videos or taking bursts of photos. The read speed affects how fast files transfer to other devices. SD cards are categorized by speed class: Class 2, 4, 6, & 10, with Class 10 offering a minimum write speed of 10 MB/s. For faster performance, UHS cards are available—UHS-I, UHS-II, or UHS-III—with speeds going up to 312 MB/s for UHS-II. There are also V-rated cards (Video Speed Class) designed for 4K & 8K video. Ratings like V30, V60, or V90 indicate minimum sustained write speeds in megabytes per second. The right SD card for your hunting camera depends on the resolution, frame rate, & data transfer requirements.

Maintaining Your SD Card

To keep your SD card working well, it’s important to format it regularly. Formatting essentially resets the card, clearing all files. It also ensures the camera & card are ‘synchronized’ & the files are stored in the correct format.

We recommend formatting your card in the camera itself, especially when using it for the first time or after it has been used in another device. Formatting in the trail camera is always better than doing it on a computer, which may alter the memory file system & cause problems.

Troubleshooting Card Issues

If your trail camera is acting up or seems to stop working, the SD card might be the issue. If you notice any of the following, it could be the card:

• ‘Card error’ messages
• Empty or unreadable files
• Camera freezing
• Failure to trigger

In these cases, try these simple fixes:

• Reformat the card: As mentioned earlier, this is the first step! Formatting often resolves many issues with trail cameras.
• Check the lock tab: Full-sized SD cards have a small switch on the left. If it’s slid down, the card is locked & no files can be saved or deleted. Slide it up to unlock.
• Try another SD card: Switching cards can help you quickly determine if the SD card is the problem or if something else is wrong.
• Check if your card is U3-rated: Some users have had issues with U3-rated cards (minimum 30MB/s write speed) when used with certain camera brands. Firmware updates for some models can fix these compatibility issues.

If the issue persists, you can contact the camera’s manufacturer for further support.
