| Resolution | Bitrate (25fps) | Hours | Days | Weeks | Months | 6 Months |
| 2560x1920 | 20Mbps | 8.8GB | 210.9GB | 1.44TB | 6.18TB | 37.08TB |
| QXGA(2048x1536) | 13Mbps | 5.7GB | 137GB | 960GB | 4TB | 24TB |
| QXGA(2048x1536) | 9Mbps | 4GB | 95GB | 665GB | 2.78TB | 16.68TB |
| QXGA(1600x1200) | 8Mbps | 3.5GB | 84.4GB | 591GB | 2.47TB | 14.82TB |
| 1080P(1920x1080) | 8Mbps | 3.5GB | 84.4GB | 591GB | 2.47TB | 14.82TB |
| 1.3MP(1280x960) | 4Mbps | 1.8GB | 43.2GB | 303GB | 1.21TB | 7.26TB |
| 720P(1280x720) | 2Mbps | 900MB | 21.09GB | 147.66GB | 632.8GB | 3.7TB |
| VGA(640x480) | 1536kbps | 675MB | 15.8GB | 110.6GB | 474GB | 2.78TB |
| 2CIF(704x288) | 1024kbps | 450MB | 10.5GB | 73.5GB | 315GB | 1.85TB |
Note: 1Mbps = 1024 kbps; 1024Mbps = 1GByte
Disclaim: only for reference, the an outcome calculated through software/table is based upon regular H.264 codec, after several years" improvement, we reckon that the H.264 video compression performance has been substantially improved, therefore data may not precise for today"s H.264 IP cameras and DVRs/NVRs.
