AXIS 221 - System Options
Network - SOCKS
SOCKS is a network proxy protocol. The camera can be configured to use a SOCKS server
to reach networks on the other side of a firewall/proxy server. This functionality is useful
if the camera is located on a local network behind a firewall, but notifications, uploads,
alarms, etc., need to be sent to a destination outside the local network (e.g. to the Internet).
Network - SMTP (email)
Enter the host names or addresses for your primary and secondary mail servers in the
fields provided, to enable the sending of event and error email messages from the camera
to predefined addresses via SMTP.
Network - SNMP
The Simple Network Management Protocol (SNMP) allows the remote management of
network devices. Select the version of SNMP to use, depending on the level of security
required. HTTPS should be enabled when setting the password for SNMPv3.
Network - UPnP
The camera includes support for UPnP, which is enabled by default. If also enabled on your
computer, the camera will automatically be detected and a new icon will be added to “My
Network Places.”
Note: UPnP must also be enabled on your Windows XP or ME computer. To do this, open the Control Panel from
the Start Menu and select Add/Remove Programs. Select Add/Remove Windows Components and open
the Networking Services section. Click Details and then select UPnP as the service to add.
Network - RTP (multicast)
Multicast must be enabled for these settings to take effect. The settings are only valid when
MPEG-4 is used as the video format. Multicast is automatically configured and should
normally not be changed. Enter the IP address and the port number to use for the video
stream in the required fields.
Only IP addresses within certain ranges can be used for multicasting. The camera has been
pre-configured with an address from these ranges, and this does not normally need to be
changed. Please contact your network administrator if you have special requirements.
Notes: •The viewers do not need to know this IP address or port number, only the main IP address or host name
used for accessing the camera.
•Setting the video port number to 0 means a random port number will be used.
If IP packets (i.e. data) fail to be delivered to their destination within a reasonable length of
time the number entered in the Time to live field tells the network routers when to discard
the packet. The value is usually measured in 'hops', i.e. the number of network routers that
can be passed before the packet arrives at its destination or is dropped.
