Applies to Models: All Hanwha IP cameras

Summary:

Recording video to an SD card puts a heavy strain on the recording media. Due to those stresses, Hanwha only recommends certain types of micro SD cards for use in our cameras.

Explanation of Behavior:

• Using certain types and brands of micro SD media causes Hanwha cameras to act erratically or reboot constantly
• Recording medium fails at a very high rate, requiring frequent changes of micro SD cards

Resolution:

• Most off-the-shelf micro SD cards bought online or from a local retailer will be consumer-grade flash memory with an approximate maximum number of writes to each memory cell of about 3,000 to 5,000 writes before a permanent failure will occur in each cell.  The quicker the overwrite cycle is, the quicker the card will degrade.  Recording on events or at lower resolution/frame rate/bit rate will increase the life span of the card.
  
  • Triple Level Cell - Consumer-grade flash 3,000 to 5,000 write cycles maximum (Not Recommended)
  • Multi-Level Cell - MLC 8,000 to 10,000 write cycles maximum (Recommended)
  • SLC - Single-Level Cell 90,000 to 100,000 write cycles maximum
• The recommended type is MLC (Multi-Level Cell)
• The recommended capacity is listed in the manual for your camera, and older units may have a lower maximum capacity. The current capacity is from 16GB to 512GB

NOTE: Hanwha puts this information in every product manual, search
the manual PDF for "MLC", the manual will list the recommended type
and size and format of SD card.  

• Currently, two manufacturers' sub-brands that are recommended for use in Hanwha IP cameras for edge recording are: 
  
  • SanDisk Industrial
  • Transcend High Endurance
