For most home security cams, a 64GB microSDXC, UHS‑I card with Class 10 performance is a practical fit. To help with smooth recording and fewer dropped frames, look for:

• Type: microSDHC/microSDXC, UHS‑I (common across cameras).
• Speed: Class 10 with U1 or U3; a V30 video rating can add headroom for higher bitrates.
• Capacity: Confirm the camera’s maximum; 64GB offers a good balance of retention and reliability for many setups.
• Endurance: Cards marketed for continuous or “high endurance” use can handle frequent overwrites.
• Setup: Format the card in‑camera (FAT32/exFAT as supported) and enable loop recording if available.

You can filter 64GB memory cards by speed class and form factor on this page, then choose pickup or delivery for convenience.

Recording time on a 64GB card depends on resolution, bitrate, compression, and whether audio is included. These ballpark examples assume continuous video:

• 1080p at ~4 Mbps: about 35 hours.
• 1080p at ~8 Mbps: about 18 hours.
• 2K at ~12 Mbps: roughly 12 hours.
• 4K at ~60 Mbps: around 2–2.5 hours.

Actual results vary by device and settings. Many cameras use loop recording, which overwrites the oldest footage when the card fills. For heavy 24/7 use, considering an endurance‑rated card can help manage constant writes. If you’d like more retention, you can add cloud or network storage when your device supports it, and keep a spare 64GB card on hand for quick swaps.

For a 2K indoor pan/tilt camera like the one you mentioned, aim for a 64GB microSDXC, UHS‑I card with solid video performance. A quick checklist:

• Speed class: Class 10 with U1 is typically sufficient for 2K; U3 or a V30 rating can offer extra margin.
• Endurance: An endurance‑rated card can be helpful for continuous or motion‑heavy recording.
• Compatibility: Verify the maximum supported capacity and file system in your camera’s manual.
• Setup tips: Format in the camera, update firmware, and set recording bitrate to balance quality and retention.

If you mainly save motion events, a 64GB card can store many days of short clips; with 24/7 recording, retention usually spans hours to a few days depending on bitrate and frame rate.

It varies with megapixels, file type, and compression. Here’s a rough guide for a 64GB card (actual counts depend on your camera’s settings):

• 12 MP JPEG (3–6 MB): about 10,000–20,000 photos.
• 20 MP JPEG (5–10 MB): about 6,000–12,000 photos.
• 24 MP JPEG (6–12 MB): about 5,000–10,000 photos.
• RAW files (20–50 MB): roughly 1,200–3,000 images.

If you shoot bursts or HDR, file sizes can increase. For trips, some photographers prefer multiple 64GB cards instead of one larger card to spread risk. Use filters on this page to find 64GB cards with the speed class your camera supports, and choose delivery or pickup for convenience.

UHS refers to the card’s bus interface speed. Both UHS‑I and UHS‑II exist at 64GB, and the right pick depends on your device and workflow:

• Device support: Many consumer devices have UHS‑I slots; pro gear may support UHS‑II.
• Recording needs: For 4K/2K capture, prioritize Video Class (e.g., V30) and U1/U3 ratings; these indicate sustained write performance.
• Compatibility: UHS‑II cards are backward‑compatible and will operate at UHS‑I speeds in UHS‑I slots.
• Transfers: If you move large files often and have a UHS‑II reader, UHS‑II can accelerate offloads.

Check your device manual to confirm slot type. On this page, you can filter by speed class to quickly narrow down 64GB cards that match your needs.
