Re: store system w 4-8 cameras ?

["Roland Moore" <roland@xxxxxxxxxxxx>]

I think you need to educate yourself a little more. Here are a few basics.
Some of the information you're getting here on this newsgroup is probably
confusing. Video uses the term CIF.  1 CIF, 2 CIF and 4 CIF are common
recording quality settings (1 lower and 4 higher). The FPS issue is also
confusing. The human eye (and brain) will see 7.5 FPS as real time (don't
argue, go actually try it and suprise yourself). Higher frame rates are only
required to detect slight of hand motions (like in a casino). Total frame
rates are a function of the robustness of a video capture card and the
system it is on. How you parse those FPS out to the individual channels can
be something to pay attention to.You need to know what you need to see, in
what detail, and for how long the images need to be stored. If there is a
cash register involved you need to understand what POS systems is being used
and if you want the data inserted as text only overlay, or made part of the
searchable events database. Once you answer those questions properly a
better recommendation can be made. There are many more video features for
image analytics that might not apply to your situation and budget.
