Disk Capacity Calculation
In the first installation of the HDD, check 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 Recorder adopts MPEG4/H.264 compression technology, which features a large dynamic range.
Therefore, when calculating HDD capacity, you should accord to the bit rate to evaluate the file size
generated per hour from each channel.
