How much space does network IP camera video file occupy?
The the bit rate of network IP camera can be adjusted. It means the video file for recording also can be adjusted.
Take the CIF video compressed by MPEG4 format for example. Its biggest bit rate is 400Kbps (“b” is bit here).
One second it needs: 400/8=50KBps (“B” is byte here. Hard disk storage is calculated by Byte)
One minute it needs: 50KBpsx60s=3000KByte=3MByte
One hour it needs: 3MBytex60m=180MByte
One day it needs: 180MBytex24h=4320MByte=4.22GByte (1G=1024M)
