3Put back the cover of HDD case, screw up the 4 screws.
3.5. Memory occupancy calculation
When you install the 4ch HDD/SD card mobile DVR for the first time,please check if any hard
disk/SD Card is installed. And check the write protect switch(if with SD card),Otherwise,the video
files can not be recorded into the SD Card properly.
Maximum capacity of the memory storage devices HDD/SD Card supported:
4CH mobile DVR X7 series support SATA HDD up to 4TB and high capacity SD Card up to
128GB. Users can choose the appropriate memory storage as their request:
How to choose HDD/SD Card`s capacity?
Formula for Storage space occupation:
Total storage capacity（M）= numbers of channels（CH）* required time（H）* occupied capacity
per hour（M/H）
Formula for recording time:
Recording time（H）= Total storage capacity（M）/【numbers of channels（CH）* occupied capacity
per hour（M/H）】
Please notes:X7 series MDVR adopt H.264 compression technology,with comparatively wide
dynamic range,and different video input devices will affect the bit stream statistics obviously. So
when users calculate the parameters above,please refer to all channels bit stream info in menu,to
make sure the calculation as accurate as possible. It will assist users to choose more appropriate
storage devices.
For instance:
The user uses a standard hard disk of 1TB/SATAII,and set 4 ch recording at 720P/25FPS(high
quality recording).Each single channel needs around 2GB capacity per hour,the recording time of
4ch real time high quality recording will be:1TB/(2GB×4CH)≈128hours(8hrs/day×16 working days
or 24 hrs/day×5 working days).
3.6. Main frame installation
