Uncompromised Speed and Multi-Variant Scalability
The Hikvision HS-TF-L2 series provides essential storage flexibility across three distinct configurations: 128GB (50MB/s write), 256GB (55MB/s write), and 512GB (55MB/s write). Designed with advanced NAND controller technology, these MicroSDXC cards feature smart read/write optimization to withstand continuous cyclic overwrite operations typical of modern surveillance systems. Furthermore, its broad compatibility extends to standard digital cameras, mobile monitoring gear, and edge devices requiring reliable Class 10 speed standards.
Surveillance-Grade NAND Flash
Utilizes high-quality TLC NAND flash memory explicitly tuned for high-density continuous video streaming, ensuring long wear-life cycle endurance under 24/7 video recording conditions.
Optimized Edge Backup Reliability
Works in tandem with ANR (Automatic Network Replenishment) features on Hikvision IP cameras, maintaining video recording redundancy during network outages and syncing automatically upon reconnect.

Which capacity variant should I select for my IP camera?
Selection depends on your camera's resolution, bitrate, and retention requirements. A 128GB card typically holds several days of continuous 1080p stream recording, while 256GB and 512GB variants are ideal for higher bitrates (4K / 8MP resolution) or longer offline retention windows.
What are the key write speed differences across variants?
All variants share an identical maximum read speed of 95MB/s. The maximum write speed is 50MB/s for the 128GB model, and increases to 55MB/s for both the 256GB and 512GB models.
Is the Hikvision L2 series compatible with standard MicroSD slots?
Yes. The HS-TF-L2 card uses the standard MicroSDXC form factor and is compatible with all devices supporting MicroSDXC expansion, including IP security cameras, digital camcorders, dash cams, and card readers.
How does edge storage protect my footage during a network outage?
When installed in an IP camera, the L2 card acts as an emergency local buffer. If network connection to the NVR is lost, footage continues recording directly to the card and automatically backfills to the NVR when connectivity restores.
