 Multicast – this connection type is efficient when multiple applications use the
cameras. This approach decreases the bandwidth usage. MPEG cameras allow sending
the images to multicast IP addresses. These addresses are reserved in the IP protocol
for multicast information distribution. To program a camera to send the images to a
multicast address, you have to configure it in the camera’s native software software.
Specify the IP address on the Connection Screen of the camera wizard.
Multicast IP addresses are in the range 224.0.0.0 through 239.255.255.255.

3.3.1.2.3 Live View
The Live View tab will appear differently depending on whether you are viewing Analogue or
IP cameras.
The following parameters can be set for an analogue camera:
 Image resolution – as a rule of thumb, the higher the quality of the image (higher
image resolution), the lower the frame rate you will have.
 Differential transmission – when differential transmission is enabled, only the
differences between subsequent images are sent over the network. This feature
drastically decreases the amount of transmitted video-data and is especially designed
to be used when viewing camera images over the Internet.
