as a reference only.

Figure 3-3

3.5 Locally Storing Data

Certain cameras include a SDHC card slot for onboard storage that support a 128 GB Micro SD card.

Dahua recommends using a SanDisk Extreme Micro SD card (or an equivalent substitute) as these

cards have been fully tested without issue and the SanDisk Extreme line is better suited for constant

recording. Lower-grade SD cards meant for multimedia applications will, at times, have questionable

quality and reliability. 

Recording to the SD card is first in first out (FIFO). The camera deletes the oldest (first) entry as new

storage requirements arise. The camera does not signal nor make an indication when data is deleted.

Storage time is dependent on a variety of factors such as SD card size, image resolution and video

frames per second. 

SD Recording supports video only. Audio is not supported. 
