Status LED 

After powering up, the Network Camera performs a self-diagnostic to detect any 

hardware defects. The following table lists the LED patterns in general. In case of any 

fatal error, the LED will blink in a pattern other than those below.

Reset and restore 

There is a button in the back of the Network Camera. It is used to 

reset the system or restore the factory default settings. 

Sometimes resetting the system sets the system back to normal 

state. If the system problems remain after reset, restore the 

factory settings and install again. 

RESET:    

Click on the button. 

RESTORE:    1. Press on the button continuously. 

2. Wait for self-diagnostic to run twice. 

3. Free the button as soon as the second self-diagnostic starts.

  Restoring the factory defaults will erase any previous settings. Reset or restore the 

system after power on.
