[IPsec] Setting IPsec5-275 Setting PageAg [SA ESP 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 theSA, be careful not to specify an inbound SPI whosevalue is already used in the SPI for other ESP.z If [Security Protocol] was set to [AH] or [ESP and AH]] in5, Ah [SA AH Authentication Algorithm] to Sq [SA AHSPI (inbound)] must be set.Ah [SA AH Authentication Algorithm]Set the AH authentication algorithm to[HMAC_SHA1_96] or [HMAC_MD5_96] according tothe authentication algorithm supported by the device toconnect to.Aj [SA AH Authentication Key (outbound)]Set the SA authentication key for outbound. If[HMAC_SHA1_96] or [HMAC_MD5_96] was selectedin Ah, set a 160-bit or 128-bit hexadecimal,respectively.Ak [SA AH SPI (outbound)]Set the SA SPI value for outbound.Set a desired value in the range of 256 to 4294967295.Al [SA AH Authentication Key (inbound)]Set the SA authentication key for inbound. If[HMAC_SHA1_96] or [HMAC_MD5_96] was selectedin Ah, set a 160-bit or 128-bit hexadecimal,respectively.Sq [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 theSA, be careful not to specify an inbound SPI whosevalue is already used in the SPI for another 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.• 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. 5-32).
