Setting the Administrator Password, LAN, IPv6, DNS, etc. (Network)
DNS
(1) [Name Server Address 1], [Name Server Address 2]
Enter each name server address you want to register. If only one address is registered,
keep the [Name Server Address 2] field blank.
(2) [Host Name Registration with DDNS]
Select [Enable] and enter the host name. The host name can be registered in the name
server.
You can use up to 63 (single-byte) characters including A to Z, a to z, 0 to 9, "-" (hyphen),
"_" (underber) and "." (period).
Tip
For added convenience, register the host name if the camera is use by [Auto (DHCP)]
( P. 1-8). Certain items must be set beforehand for registration in the DNS server. For
the DNS server settings, contact your System Administrator.
If [Name Server Address 1] cannot be used, [Name Server Address 2] will be accessed.
However, [Name Server Address 2] must be already set.
SNMP
(1) [SNMP]
Select whether to use SNMP from [Disable] or [Enable]. When [Enable] is selected, the SNMP
Manager can reference information set in the camera.
(2) [Community Name]
Set a community name for SNMP. It is recommended that you change the default community
name to ensure security of the system.
(3) [Administrator Contact Information]
Set contact information (e-mail address, etc.) for the Administrator of the camera. The set
details can be referenced by the SNMP Manager.
