For IPsec communications, the device to connect must be compatible with IPsec.
Depending on the device, communications may not be possible or the communication speed may be slow.
On this camera, IPsec operates in transport mode only and uses IKEv2.
The algorithm is AES with 128-bit keys in CBC mode/Diffie-Hellman 3072-bit modp group/PRF-HMAC-SHA-256/HMAC-SHA-
384-192.
The authentication expires after 24 hours.
Encrypted communications can only be made with devices that are configured correctly. Communications with other devices are
not encrypted.
For details on the IPsec configuration, consult the administrator of the network for your device.
