SSL
Configure the SSL or TLS function (called “SSL”
hereafter). The settings allow the camera to
communicate with the client computer by using
SSL.
Notes
• When using the SSL function, always configure
the settings after setting the date and time of
the camera. If the date and time are not
correctly set, it may cause web browser
connection problems.
• Reload the window when you change the SSL
se
tting. Press the F5 key on the keyboard to
reload.
When you use SSL connection for the first time
When you use SSL connection only by setting the
S
SL function to [Enable], you cannot access the
camera if the SSL function does not work
properly.
In this case, you must reset the camera to the
f
actory settings. (All settings will be initialized.)
To avoid this, check that SSL connection is
p
ossible by performing the following steps.
1 Set the SSL function to [Enable (Allow HTTP
connection for some clients)].
2 Click [OK] to close the web browser.
3 Display the viewer in SSL connection.
For details, see “When the SSL Function is
Used” (page 49).
4 After confirming that SSL connection is
possible, set the SSL function to [Enable].
Even if the web browser is closed as SSL
c
onnection is impossible, HTTP connection will
be possible if [Enable (Allow HTTP connection for
some clients)] is selected. First check the setting
contents of the SSL tab in HTTP connection, then
check the SSL connection again.
If [Enable (Allow HTTP connection for some
clie
nts)] is not selected, you will not be able to
access the camera when SSL connection
becomes impossible. In this case, press the reset
switch on the camera for 5 seconds or longer to
return to the factory default settings. For details,
see page 8.
Note
SSL connection will apply load to the camera;
therefore, not all images may be downloaded,
and the mark may appear when the camera
accesses from the web browser. In this case,
r
eload the window. Press the F5 key on the
keyboard to reload.
SSL Server Authentication
Certificate Options
Select an installation mode of the certificate.
[Use an external certificate]:
Uses the certificate
including private key information issued by a
CA. The PKCS#12 and PEM formats are
supported.
Note
SSL is not available when [Certificate Options]-
[Use an external certificate] is selected, or a
certificate and private key password is not set
properly even if SSL is set to [Enable].
[Use a self-signed certificate (For test use)]:
This mode uses the certificate and private key
pair generated by “Self-Signed Certificate
Generation” (page 79). Private key information
corresponding to the certificate is stored in the
ca
mera.
You do not need to install an external
certificate. However, you cannot execute
the existence proof, which is one of the SSL
functions, for the following reasons.
– The private key generated in the camera
is se
lf-signed by the camera.
– A prepared value is set for a
d
istinguished 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, such as
for operation tests, is not ensured.
Notes
• When [Use a self-signed certificate (For test
use)] is selected, the Security Alert dialog
appears on the SSL connection with a web
browser.
For details, see “When the SSL Function is
Used” (page 49).
• When [Use a self-signed certificate (For test
use
)] is selected, you may not be able to use
the SSL connection depending on the web
browser or OS you are using.
To import the certificate
Click [Import] to select the certificate to be
imp
orted. Follow the on-screen instructions to
import the certificate to the camera.
