Now take the Main-stream(Sub-stream is used for uploading
)
table for example.
It is an approximate data for
one camera in one hour
, eg.
720P
, if the
Quality is 1
(best), from the table,
we know it will take up
1800MB /hour
.
Take ME41-04 for example, suppose it has
4
cameras, and work
10
hours everyday in one month (
30
days).
Total
= 1800MB*
4
(cameras)*
10
(hours)*
30
(days)=2160000MB ≈ 2109GB. And you need a 2TB HDD at
least.
