OTE The storage capacity for the same image will be different. Image per byte is ratio to the image dimensions
(horizontal x vertical), thus 720×240/288(2CIF) is twice the size of 352×240/288(CIF), and
720×480/576(D1) takes about 4 times the storage capacity. Therefore, when high resolution is selected
for the same period, the storage capacity taken up will be larger, and the storage period will be shorter on
the same Hard disk capacity.
N
OTE For the same resolution, frame per byte size will vary according to various reasons such as the recorded
picture quality setting, movement, complexity of the image, and noise. Therefore, the total recording
period will differ hugely according to the specific image conditions.
