Auto Key Exchange Settings
[IPsec SA Encryption Algorithm]
Select the IPsec SA encryption algorithm.
The specified algorithm will be checked for an applicable encryption algorithm starting from the left.
[IPsec SA Authentication Algorithm]
Select the IPsec SA authentication algorithm.
The specified algorithm will be checked for an applicable authentication algorithm starting from the left.
[IPsec SA Validity Period (min)]
Enter the duration of validity for IPsec SA.
[ISAKMP SA Encryption Algorithm]
Select the SA encryption algorithm for use with auto key exchange protocol IKE.
[ISAKMP SA Authentication Algorithm]
Select the SA authentication algorithm for use with auto key exchange protocol IKE.
[DH Group]
Select the key generation information that will be used in the DH algorithm for key exchange via auto key exchange protocol
IKE. The higher the group number, the stronger security will be.
[ISAKMP SA Validity Period (min)]
Enter the duration of validity for ISAKMP SA.
IPsec Set 1 to 5
IP security can be specified through auto key exchange or manual setting with up to five communicating devices.
Auto Key Exchange
Note
If auto key exchange is used, it will take approximately 5 to 10 seconds before communication with the camera starts.
[IPsec Set]
Select which IPsec sets the camera will use; IPv4, IPv6, or neither.
[IPsec Mode]
Select the IPsec mode.
[Destination IPv4 Address], [Destination IPv6 Address]
Enter the IP address of the connection destination.
[Source IPv4 Address], [Source IPv6 Address]
Enter the IP address of the source.
[IPsec Protocol]
Select the IPsec protocol.
If you select [ESP], enter only the setting items relating to ESP.
If you select [AH], enter only the setting items relating to AH.
If you select [ESP and AH], enter all setting items.
[Security Gateway IPv4 Address], [Security Gateway IPv6 Address]
Enter the IP address of the security gateway if [IPsec Mode] is set to [Tunnel Mode].
[Destination Subnet Mask Length], [Destination Prefix Length]
Enter the subnet mask (IPv4) or prefix length (IPv6) when [IPsec Mode] is set to [Tunnel Mode].
Important
If the camera is rebooted during auto key exchange communication, a connection error may result after rebooting. If this occurs,
connect again.
