Setting the SSL function — SSL Menu
50
Use a self-signed certificate (For test use): This mode
uses the certificate and private key pair generated by
“Generating a self-signed certificate” on page 50.
Private key information corresponding to the
certificate is stored in the camera.
You do not need to install an external certificate.
However, you cannot execute the existence proof that
is one of the SSL functions for the following reasons.
– The private key generated in the camera is self-
signed by the camera.
– A prepared value is set for a distinguished name
(Common name, etc.).
– The certificate is not issued by a trusted CA.
For reasons of security, we recommend using this
mode only when there is no problem even if perfect
security is not saved.
Notes
•When Use a self-signed certificate (For test use) is
selected, the Security Alert dialog appears on the
SSL connection with a browser.
For details, refer to “Using the SSL function”
(page 15).
• SSL connection may be impossible due to the type of
certificate installed in the camera. In this case, refer to
“How to install the CA certificate” on page 52 and
install.

To display certificate information
When the certificate has been set in the camera correctly,
its information appears on Status, Issuer DN, Subject
DN, Validity Period and Extended Key Usage.
Status

The following statuses are recognised.
Valid: The certificate is correctly stored and set.

Possible causes are as follows:
– Use an external certificate is selected and the
private key password included in the certificate is
not specified correctly.
– Use an external certificate is selected and the
private key password is specified in spite of the fact
that the key pair in the certificate is not encrypted.
– Use an external certificate is selected and the key
pair is not included in the certificate.
– Use a self-signed certificate (For test use) is
selected without the self-signed certificate being
generated.
Note
When the certificate to be imported is of PKCS#12
format and the private key password is not set correctly,

Extended Key Usage. Specify the correct private key
password to confirm the information of the certificate.
