4Kvideo recording support

The UNIS TF Card high-speed series comes from UNIS Flash Memory in four capacities: 32, 64, 128 and 256 GB. The manufacturer's published figures are straightforward — C10 / U3 / A1 speed classes, read speed up to 100 MB/s, 4K video recording support, and a waterproof, shockproof, heat-resistant build. That makes it a solid general-purpose card for dashcams, home and entry-level surveillance, phones and drones. Two honest notes: the factory poster does not publish write speed, P/E endurance or operating-temperature figures — corporate buyers can request the original datasheet on WhatsApp; and for 7×24 continuous CCTV recording our default recommendation is still the UNV Red Card MT series — this UNIS card is the better fit for event-based recording and personal devices.

Is this the right card for you?

Plain-language guide — based only on what this product actually does.

DashcamsThe U3 class keeps high-bitrate loop recording steady, and the waterproof, heat-resistant build suits life on a hot windshield.

Home & entry-level camerasFor motion-triggered, event-based home cameras this is a sensible local-storage pick — for 7×24 recording, step up to the Red Card MT.

Phones & dronesUp to 100 MB/s reads and the A1 class keep photo libraries, offline media and 4K drone clips responsive.

Not the right pick if you need…

7×24 continuous CCTV recording — our default pick for that duty is the UNV Red Card MT series (3000 P/E, −25–85 °C); this UNIS card fits event recording and personal devices
Published write-speed, P/E endurance or operating-temperature figures — the factory poster does not list them; corporate buyers can request the original UNIS datasheet on WhatsApp before committing a project
Off-the-shelf 256 GB delivery — that capacity is made to order; confirm the production lead time on WhatsApp first

High-Speed TF Card FAQ — UNIS TF Card Series

Can the UNIS card record 4K video?

Yes, 4K video recording is supported. The cards carry C10, U3 and A1 ratings and reach up to 100 MB/s sequential read. The U3 class is the one that matters for 4K — it guarantees the sustained write performance that 4K capture requires, across all four capacities from 32 to 256 GB.

Which devices is it intended for?

The factory lists dashcams, home surveillance cameras, phones and drones as typical devices. Note the card types: 32 GB is microSDHC while 64, 128 and 256 GB are microSDXC, so confirm that older devices accept SDXC before you standardise on 64 GB and above.

What capacities are in regular stock?

32 GB, 64 GB and 128 GB are regular stock. The 256 GB card is made to order, so allow extra lead time if a project needs the largest capacity. All four capacities share the same C10/U3/A1 ratings and up-to-100 MB/s read speed.

What are the write speed and endurance figures?

The factory poster does not publish write speed, endurance or operating-temperature figures for this series, and we will not guess at numbers. The published specs are read speed up to 100 MB/s and C10/U3/A1 classes. Ask on WhatsApp and we will request the original UNIS datasheet for you.

How durable is it for outdoor use?

The cards are specified as waterproof, shockproof and heat-resistant, which suits dashcams parked in the sun and cameras or drones working outdoors. The exact operating-temperature range is not on the factory poster, so request the UNIS datasheet if your installation has a hard temperature requirement.

How is export shipping handled?

For small and mid-size orders we deliver directly to your designated freight forwarder's warehouse in China on EXW or FOB Guangzhou terms, so the international leg runs under your forwarder's rates and schedule. Send your capacity mix and quantities on WhatsApp and we will quote.
