62identifying the SA, be careful not to specify aninbound SPI whose value is already used in the SPI forother ESP.z If [Security Protocol] was set to [AH] or [ESP and AH] in(5), (16) [SA AH Authentication Algorithm] to (20) [SAAH SPI (inbound)] must be set.(16)[SA AH Authentication Algorithm]Set the AH authentication algorithm to[HMAC_SHA1_96] or [HMAC_MD5_96] according tothe authentication algorithm supported by the deviceto connect to.(17)[SA AH Authentication Key (outbound)]Set the SA authentication key for outbound. If[HMAC_SHA1_96] or [HMAC_MD5_96] was selectedin (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 to4294967295.(19)[SA AH Authentication Key (inbound)]Set the SA authentication key for inbound. If[HMAC_SHA1_96] or [HMAC_MD5_96] was selectedin (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 to4294967295. Since this setting is used as an ID foridentifying the SA, be careful not to specify aninbound SPI whose value is already used in the SPI foranother AH.NoteIf IPsec is used, video transmission performance drops.Important• To run this camera with IPsec, the communicating devicesand network must be set beforehand. Contact your SystemAdministrator for these settings.• When connecting with IPsec, set the camera IP addressmanually.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 cameramay become inaccessible from the active web browser.Check beforehand the precautions in “Important” in “[RebootItem] Setting Items Requiring Rebooting” (p. 70).
