Cctv calculator

The following two metrics should provide a range: 80% of surveillance cameras use between 60GB to 600GB of storage . 99% of surveillance cameras use between 6GB and 6TB of storage.

First, calculate the raw storage capacity required by a single video every day. Calculate the raw storage capacity required by a single video for 30 days. Finally, calculate the raw storage capacity of 100 channels of videos in 30 days. [2Mb/s*3600s/h*24h]/8*30*100=63300GB/1024=61.8T.

CCTV Camera Storage Calculation Formula

If we take a camera capturing an image at D1 (DVD) resolution, viz. 720 x 480, and transmitting at 30 fps (frames per second); the relevant numbers add up as follows: Frame Size = (720*480)*24 = 829440 bits = ~ 830 Kbps (Kbits/sec) Bit Rate = 829440 *30 = 248832000 = ~ 250 Mbps (Mbits/sec)
