the background. You can change its position or color when this
happens;
4) Image size is the format used when recording. Remote image size is
the format used when these images are transmitted to client sides;
5) Remote Frame Rate, Remote image size and Remote Quality are the
parameters of the client side.
①
When the serve
r’s image size is set as
“704*576(12fps)”, the three items are no effect, and client’s
parameters will be the same with server.
②
When the server’s resolution
is set as others (except
“704*576(12fps)”), if Remote image size is set
as “Same as Rec”, Remote frame rate (fps) and Remote Quality are
no effects, the client’s parameters will be the same with server;
6) Variable digital rate table:
Image quality
record environment
occupied disk space (com/hour)
Poorest
Low action, indoor
about 45Mb
high action, road
about 95Mb
medium
Low action, indoor
about 70Mb
high action, road
about 180Mb
best
Low action, indoor
about 160Mb
high action, road
about 320Mb
Invariable digital rate can’t improve image quality but it is helpful for
calculating disk space. Variable digital rate recording is recommended.
