RECORDING TIME CALCULATION
Please confirm the HDD has been installed when install GVR3550/GVR3552 the first time.
HDD Capacity formula is:
Total HDD Space (M) = the amount of cameras * required time (Hour) * the HDD space occupied per
hour（M/H）
From the formula above we could conclude the recording time formula:
Recording Time (hour ) = Total HDD Space (M)/the HDD space occupied per hour（M/H）*the amount
of cameras
GVR3550/GVR3552 is equipped with MPEG4/H.264 compression technique, its dynamic range is quite
large thus the HDD capacity calculation based on assessing the video file size each camera recorded per
hour.
e.g.:
The video one single camera records per hour takes up 200M/H in HDD, use GVR3550 to record
synchronously with 12 cameras.
Record Time (hour) = 2*4*1024*1024/200（M/H）*12=3495.25（Hour）»145.6（Day）
