How do you calculate video recording?

Simply divide the horizontal pixels of the camera resolution by the Field Of View in feet (FOV) of the observed scene . For example, a 4-megapixel camera with 2,688 horizontal pixels used to cover a loading dock with a 100-foot FOV, pixel density would be approximately 27 PPF.

However, as a rule of thumb, at the recommended resolution (1080p), recommended frame rate (6fps) and recommended normal 24/7 recording if 500GB is allowed for each camera 24 days of footage will be stored .

Depending on the number of cameras you have connected to the DVR and the recording resolution of those cameras, generally: 500 GB = up to 6 months of recording 1 TB = up to 12 months of recording 2 TB = up to 24 months of recording The more cameras you have connected to the DVR, the shorter this time frame.

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.
