13.3 Sub-Stream Recording Parameters
The following table is valid for both the MDR-404xx-500 using all 4 channels and MDR-408xx-1000 using all 8 channels. It illustrates
approximate SD recording times in hours at CIF resolution and different frame rates. Ranges of frame rates are controlled by the sub-stream
bandwidth. Refer to section 4.1.5 Sub-Stream Settings.

video loss record video loss information 1.vloss channel 1 vloss; Record how many channels lost video
It is considered power cut off
when the voltage value falls
under 7V. 2.vloss electricity was cut off; MDR Powers off when circuit protection
kicks in
3.vloss electricity was cut off stop
record fail; Power is cut off, and MDR processing
video.
4.vloss power was supply; Voltage was pulled up to normal level
and MDR stops using internal
capacitance.
