3.3  Framework and Dimensions 

The following figures show the dimensions of the device in mm [in.]. These images are intended 

as a reference only. 

 

Figure 3-2 

3.4  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. 

 

3.5  Alarm Setup 

Certain devices support alarm inputs and outputs, check your specific device for alarm capability.  

Alarm Input 

Refer to Figure 3-3 for alarm input configuration. The device collects that status of the alarm input port 

when the input signal is idle or grounded. If the input signal is connected to the 3.3 V or it is idle then 

the device receives the alarm input signal. If input signal is grounded, then no alarm input signal is 

detected.
