8 [IKE Pre-Shared Key]
Enter the pre-shared key for IKE (auto key exchange)
(up to 127 characters).
Note
If auto key exchange is used, it will take approximately 5 to 10
seconds before communication with the camera starts.
IPsec Set (Manual)
IPsec Sets 1 to 5 are available, and you can specify IPsec
settings for one communication device for each IPsec Set.
1 [IPsec Set]
Set IPsec Set to [Disable], [Enable in IPv4] or [Enable
in IPv6].
2 [IPsec Mode]
Set IPsec mode to [Tunnel Mode] or [Transport Mode].
3 [Destination IPv4 Address], [Destination IPv6 Address]
Enter the IP address of the connection destination.
4 [Source IPv4 Address], [Source IPv6 Address]
Enter the IP address of the source.
5 [Security Protocol]
Set the IPsec protocol to [ESP], [AH] or [ESP and AH].
If [ESP] is selected, enter only the setting items relating
to ESP.
If [AH] is selected, enter only the setting items relating
to AH.
If [ESP and AH] is selected, enter all setting items.
6 [Security Gateway IPv4 Address], [Security Gateway
IPv6 Address]
If IPsec mode is set to [Tunnel Mode] in 2, set the IP
address of the security gateway.
7 [Destination Subnet Mask Length (IPv4)], [Destination
Prefix Length (IPv6)]
This setting is required only if [IPsec Mode] is set to
[Tunnel Mode] in 2.
If IPv6 is used, enter a desired prefix length for the
connection destination in the range of 16 to 128.
If IPv4 is used, enter a desired length in the range of 1
to 32.
• If [Security Protocol] is set to [ESP] or [ESP and AH] in
5 , 8 [SA ESP Encryption Algorithm] to A g [SA ESP
SPI (inbound)] must be set.
8 [SA ESP Encryption Algorithm]
Set the ESP encryption algorithm to [AES], [3DES],
[DES] or [NULL] according to the encryption algorithm
supported by the device to connect to.
Normally [AES] or [3DES] is recommended.
9 [SA ESP Authentication Algorithm]
Set the ESP authentication algorithm to
[HMAC_SHA1_96], [HMAC_MD5_96] or [No
Authentication] according to the authentication
algorithm supported by the device to connect to.
If [ESP] is used alone, [No Authentication] cannot be
selected.
A q [SA ESP Encryption Key (outbound)]
Set the SA encryption key for outbound. If [AES],
[3DES] or [DES] was selected in 8, set a 128-bit,
192-bit or 64-bit hexadecimal, respectively. This item
need not be set if [NULL] was selected.
A a [SA ESP Authentication Key (outbound)]
Set the SA authentication key for outbound. If
[HMAC_SHA1_96] or [HMAC_MD5_96] was selected
in 9, set a 160-bit or 128-bit hexadecimal,
respectively. This item need not be set if [No
Authentication] was selected.
A s [SA ESP SPI (outbound)]
Set the SA SPI value for outbound.
Set a desired value in the range of 256 to 4294967295.
A d [SA ESP Encryption Key (inbound)]
Set the SA encryption key for inbound.
If [AES], [3DES] or [DES] was selected in 8, set a
128-bit, 192-bit or 64-bit hexadecimal, respectively.
This item need not be set if [NULL] was selected.
A f [SA ESP Authentication Key (inbound)]
Set the SA authentication key for inbound.
If [HMAC_SHA1_96] or [HMAC_MD5_96] was selected
in 9, set a 160-bit or 128-bit hexadecimal,
respectively. This item need not be set if [No
Authentication] was selected.
Important
If the camera is rebooted during auto key exchange
communication, a connection error may result after rebooting.
In this case, connect again.
