Domain name Enter the alphanumerical name of a domain into the Domain name field if
you want to block the access of computers within this domain. For example,
enter the domain name foobar.com to hinder the transfer of the images to all
the computers within the domain foobar.com.
Procedure NetCam sends a query to the nameserver to get the numerical IP address
belonging to the domain provided. You will receive a message, should the
query lead to an error. The provided domain will not be placed on the
Banned Clients list.
IP Address(es) You can provide a numerical IP address or an entire address range in the IP
adresse(s) group to exclude the computer in question.
From, to Enter the limit of the address range to be excluded in the from and to fields.
Image options In the Image Options tab you can set the quality of the transferred images
and thus influence the transfer rate.
Image quality Use the Image Quality slide control to control the compression of the imag-
es. Move the slide control to the right to maintain a high image quality. The
data amount of the transferred images increases, whereby the transfer rate
decreases. Move the slide control to the left to increase the compression.
The image quality decreases, whereby the transfer rate increases.
Image quality and data
transfer rate
A single image of ColorView III can have the size of up to 15 MByte. Images
of this size take a long time to transfer to a client even with a very fast net-
work connection; the live-image effect is thus lost. Therefore the images are
compressed for transfer. The used algorithm is equivalent to that used with
JPEG images. Thus, high compression rates are achieved with decreased
image quality.
The amount of compression achieved is based on the image type. Images
with large, unison colored areas can be compressed more than detailed im-
ages without these characteristics.
