Appendix B Calculate Recording Capacity
Users can calculate the size of hard disk according to the saving time and DVR recording settings. The DVR uses fixed video bit rate. The below are the
details at different settings.
Resolution Frame Rate Totally (FPS) Video Quality Bit Rate (kbps) Used Space (MB/h)
720P
or
1080p
25 (PAL) / 30 (NTSC)
12 (PAL) / 15(NTSC)
Highest 6144 2700
Higher 5420 2250
Medium 4096 1800
Low 3072 1350
Lower 2048 900
Lowest 1024 450
The calculation format is: Total Recording capacity = Used space per hour (MB/h) (coverage rate of hard disk) × recording time (hour) × channel
numbers
For instance, one customer uses NTSC cameras, set resolution to 720P, video quality to Lowest, frame rate to 30 fps for enabling total 4 channels. He wants
the unit to record continuously in a month. Below is the calculation:
Total Recoding capacity = 450 (mb/h) × 24(hours/day) × 30(days) × 4(channels) = 1296000 (MB) ≈ 1266(GB)
Therefore, you need to install one 2 TB SATA HDD for recording in one month.
