Storage Capacity Calculation
Appendix 2
When the Device is installed for the first time, make sure the HDD (or SD card) is installed.
Capacity calculation formula:
Total capacity (M) = Channel quantity × Demand time length (hour) × storage capacity occupied
per hour (M/hour)
Recording time calculation formula:
Recording time (hour) = Total capacity (M)
Storage capacity occupied per hour (M/hour) × Channel quantity
The Device 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.
