Product Description
24-7 Surveillance TF Card for Continuous Write in IP NVR Security Cameras
A security camera never pauses recording, so the card inside it must treat continuous write as the normal case. This surveillance TF card is tuned for recorders that push several video streams to one card day and night: on this surveillance TF card a reserved block pool handles garbage collection, bad block management runs in the background without interrupting the stream, and card health is exposed to the host so the NVR can raise a warning before a card fails. Every surveillance TF card batch is validated on IP NVR platforms with a seven day continuous write test, and the firmware is locked so a camera update cannot change the write behaviour the recorder depends on.

- Stream tuned write cache — The cache is managed for an uninterrupted stream, so a surveillance TF card sustains multi channel recording without the stalls that appear when a general purpose card runs out of free blocks.
- Background bad block management — Defective blocks are retired in the background and replaced from the reserved pool, so the surveillance TF card keeps video flowing and protects the index file the NVR uses to locate footage.
- Health monitoring support — Wear level, spare block count and power cycle count are reported to the host, so a surveillance TF card can be swapped during a scheduled visit instead of after a recording gap.
- Power interruption recovery — The file table on the surveillance TF card is rebuilt after an unexpected shutdown, so recorded evidence is still listed and playable when site power returns.
- Low heat in sealed housings — A low power controller keeps die temperature down inside compact dome and bullet housings, the usual cause of early card loss on outdoor cameras.
- Recorder compatibility — Pre tested with mainstream NVR platforms on FAT32 and exFAT volumes, including loop overwrite and event snapshot modes.
This surveillance TF card suits sites that record without interruption:
- Retail shops using standalone IP cameras
- Warehouses and loading docks with 24 hour coverage
- Residential compounds and door station cameras
- Remote sites where a local card is the only recording layer
- Construction sites with temporary solar powered cameras
- Parking garages with wide temperature swings
A: With 64GB and a mainstream 4MP stream the loop overwrites every three to five days. Under that workload the card is specified for a multi year service window, and the health registers show when it is time to swap it.
A: Continuous write wears one region of the array first. This surveillance TF card rotates blocks, reserves spare capacity for garbage collection and keeps the index consistent, which a general purpose card does not do.
A: It follows SD6.0 and UHS-I, so it is recognised without a driver on the common NVR platforms. Tell us your camera model and we will confirm the tested combination.
A: Yes. Volume, cluster size and label can be set at production, and a printed site or asset number can be added for fleet deployments.
Production runs on our own automated lines with a seven day continuous write burn in for every batch, so failures are screened before packing. Samples ship in three to five working days, bulk orders in ten to fifteen days, and buffer stock of popular capacities is held for project orders.
