IP Security (IPsec)
Configured in [TCP/IP]
IPsec is a set of standards for encrypted communication over the
Internet. It provides effective security for both wireless and wired LANs.
To use this function, you must enable IPsec in the network settings of
your computer. When IPsec is employed, only transport mode is
supported, and 3DES or AES encryption and SHA1 authentication are
used. Note that the IP address of the computer for communication with
the camera must be entered in [Destination address] on the settings
screen.
