The resolutions of video surveillance images include CIF, D1,720P, and 1080P. These resolutions have typical bit rates such as 512Kbps, 1Mbit/s, 2 Mbit/s, 4 Mbit/s, and 8 Mbit/s. In fact, regardless of the analogimage or digital image, the video storage space is calculated based on the bitrate.
The storage capacity is calculated based on the bit rate. The formula for calculating the storage capacity is as follows:
1 hour storage capacity of a camera with the bit rate of n (unit: Mbit/s)=[(n/8) *3600]/1024 GB
Formula parsing:
n Mbps/8 Conversion unit: n MBps
n MBps*3600 Calculate the storage capacity in one hour (unit: MB).
n *3600/1024 The unit is GB.
