Solved Question(s) about security camera systems

Specs: several
Can anyone tell me how security camera systems with a
large number of high-resolution cameras is able to record
the video from al those cameras simultaneously? We are
going to have 24 cameras in this building, and wonder how
that many feeds can be recorded simultaneously. Are the
disk drives specially made? Are there a large number of
drives? Does a single drive record on multiple tracks
simultaneously? Or are all those video feeds compressed
into a single, ludicrously high-speed data stream that can
be recorded by a single head in the disk drive? Or what?

The cameras will be 30 fps and might be anywhere from
2-9 megapixels each.

morning,

western digital makes special hard drives build to be constanlty written to i think its WD purple, should be a video on youtube explaining the colors.

we actually had a company build a 16 camera setup for us about 12 years ago, 30fps 720p or so.
all i remember was that you could watch all 16 feeds back simultainiously or seperately, you could also watch them individually or all at once on the TV.

and i think we had up to 2 weeks recorded, before the data would be overwritten.

we did get robbed, while we were at home... we must have been studied for months.

We have a dogg now, big ass berner sennen :)
