1. SNMP host address / 2. SNMP host address
The NWC-0495 supports the SNMP (Simple Network Management Protocol) for
managing and monitoring network components, and can send SNMP messages
to IP addresses. It supports SNMP MIB II and its traps in their full functionality
in the unified code. If you wish to send SNMP traps, enter the IP addresses of
one or two required target devices here.
Multicasting
In addition to a 1:1 connection between an encoder and a single receiver
(unicast), the camera can enable multiple receivers to receive the video signal
from an encoder simultaneously. This is either done by duplicating the data
stream in the unit and then distributing it to multiple receivers (multi-unicast) or
by distributing an individual data stream in the network itself to multiple
receivers in a defined group (multicast). You can enter a dedicated multicast
address and port for each stream. You can switch between the streams by clicking
the associated tabs.
Note
The prerequisite for multicast operation is a multicast-capable network that
uses the UDP and IGMP protocols. Other group membership protocols
are not supported. The TCP protocol does not support multicast
connections.
A special IP address (class D address) must be configured for multicast operation
in a multicast-enabled network. The network must support group IP addresses
and the Internet Group Management Protocol (IGMP V2). The address range is
from 225.0.0.0 to 239.255.255.255. The multicast address can be the same for
multiple streams. However, it is then necessary to use a different port in each case
so that multiple data streams are not sent simultaneously using the same port and
multicast address.
