microSD Card Compatibility for Tapo and Kasa Security Cameras

Adding a microSD card (sold separately) to your Tapo or Kasa security camera enables local storage for recordings, giving you a cost-effective alternative to cloud-based subscriptions. This page covers four key topics: a tested compatibility list, buying tips, how to identify fake cards, and estimated recording hours by card capacity.

Key Takeaways

• Generally, Tapo cameras and hubs support microSD cards up to 512GB; Kasa cameras support up to 256GB. Supported capacity may vary by model and hardware version. For detailed specifications, please refer to the product page on our official website.
• A minimum speed rating of Class 10 (U1/V10) or higher is required for reliable recording.
• High Endurance, Max Endurance, or Pro Endurance cards are strongly recommended for continuous recording.
• ADATA (A1, V10) and Samsung 256GB EVO Plus (U3, V30, A2, SDXC1) are confirmed incompatible with all Tapo and Kasa cameras.
• Always buy from an authorized seller. Counterfeit and low-quality cards are a common cause of recognition and formatting failures.

Compatibility List of microSD Cards We've Tested

The table below lists microSD cards that have been tested for compatibility with Tapo and Kasa cameras in our lab. Note that test results confirm compatibility, but actual stability depends on the individual card's quality.

Note:

• microSD cards use flash memory technology, which has a limited number of write cycles. Each write operation gradually wears down the flash chips. High Endurance cards are specifically designed for continuous recording and are the recommended choice for home security cameras.
• Based on lab testing, the ADATA (A1, V10) and Samsung (256GB, EVO Plus, U3, V30, A2, SDXC1) are not supported by any Tapo or Kasa cameras.

microSD Card Buying Tips

Choosing the right microSD card for your security camera makes a real difference in recording reliability. Here are the key specifications to look for.

Minimum recommended specs:

The minimum recommended speed class is Class 10 / U1 / V10. Cards below this threshold may not support continuous video recording reliably.

Additional tips:

• Choose High-Endurance, Max-Endurance, or Pro-Endurance microSD cards wherever possible. These are designed for continuous recording and re-recording and offer much greater stability than standard cards. Regular cards designed for digital cameras are not recommended for home security cameras or monitoring applications.
• Supported capacity varies by camera model and hardware version. Check your specific product page on the TP-Link website for confirmation.
• Always purchase from an authorized seller. Avoid cheap, used, or refurbished cards.
• Pay attention to the operating temperature range listed in the card's specifications.
• microSD cards have a limited lifespan for reading and writing. Plan to replace your card every few years to reduce the risk of failure.
• Due to the wide variation in card quality, TP-Link cannot guarantee 100% compatibility with every card purchased. Test your card immediately after purchase.

Verify Fake microSD Cards

Counterfeit microSD cards are a leading cause of issues such as unrecognized cards, formatting failures, or cameras unable to overwrite recordings. The most common type is a fake-capacity card, where a small-capacity card has been modified to appear larger. Since the camera formats and indexes the card's entire storage space, a card with falsified capacity will fail to format correctly and will not work with your camera.

For detailed steps on how to identify and test for a fake microSD card, see how to verify fake microSD cards. Testing immediately after purchase is strongly recommended.

Maximum Recording Hours

The table below shows estimated recording durations at various resolutions and card capacities. These figures are based on average video bitrate measured in lab conditions. Actual recording time will vary depending on scene complexity, the proportion of motion in the footage, frame rate settings, and the resolution supported by your specific camera model.

When Loop Recording is enabled, your camera will automatically overwrite the oldest footage once the card is full, so recording never stops. For help setting up continuous recordings, see how to view continuous recordings of Tapo and Kasa cameras on the Tapo app.
