identifying the SA, be careful not to specify an 
inbound SPI whose value is already used in the SPI for 
other ESP.

If [Security Protocol] was set to [AH] or [ESP and AH]] in 
(5), (16) [SA AH Authentication Algorithm] to (20) [SA 
AH SPI (inbound)] must be set. 
(16)[SA AH Authentication Algorithm] 
Set the AH authentication algorithm to 
[HMAC_SHA1_96] or [HMAC_MD5_96] according to 
the authentication algorithm supported by the device 
to connect to. 
(17)[SA AH Authentication Key (outbound)] 
Set the SA authentication key for outbound. If 
[HMAC_SHA1_96] or [HMAC_MD5_96] was selected 
in (16), set a 160-bit or 128-bit hexadecimal, 
respectively. 
(18)[SA AH SPI (outbound)] 
Set the SA SPI value for outbound. 
Set a desired value in the range of 256 to 
4294967295.
(19)[SA AH Authentication Key (inbound)] 
Set the SA authentication key for inbound. If 
[HMAC_SHA1_96] or [HMAC_MD5_96] was selected 
in (16), set a 160-bit or 128-bit hexadecimal, 
respectively. 
(20)[SA AH SPI (inbound)] 
Set the SA SPI value for inbound. 
Set a desired value in the range of 256 to 
4294967295. Since this setting is used as an ID for 
identifying the SA, be careful not to specify an 
inbound SPI whose value is already used in the SPI for 
another AH.

• To run this camera with IPsec, the communicating devices 
and network must be set beforehand. Contact your System 
Administrator for these settings. 
• When connecting with IPsec, set the camera IP address 
manually.
For IPv4 addresses, use addresses set with [Network] > 
[IPv4 Address Setting Method] > [Manual].
For IPv6 addresses, use addresses set with [Network] > 
[IPv6 Address (Manual)].
• If any setting is changed from the [IPsec] menu, the camera 
may become inaccessible from the active web browser.
