HDD Capacity Calculation
Appendix 2
For the first time to install HDD, make sure whether the HDD is already installed. To install IDE
HDD, pay attention to the jumper of the HDD.
HDD capacity calculation formula:
Total capacity (M) = Channel number × Demand time length (hour) × HDD capacity occupied
per hour (M/hour)
Recording time calculation formula:
Recording time (hour) =
HDD total capacity (M)
HDD capacity occupied per hour (M/hour) × Channel number
The video recorder adopts MPEG4/H.264 compression technology, which fluctuates greatly.
Therefore, when calculating HDD capacity, you should accord to the bit rate to calculate the file
size generated per hour from each channel.
