When I install the Built-in Viewer,
authentication by VeriSign appears.
The Built-in Viewer has an electronic signature for
authentication by VeriSign.
If computers are connected to the Internet in the
network environment, the digital certificate of the
Built-in Viewer can be checked by VeriSign
authentication.
Videos sent via TCP do not play.
The camera can transmit a maximum of 40 videos
via TCP, and a maximum of 20 Built-in Viewer can
be connected to 1 camera.
If you set the JPEG Streaming to "Framerate", the
frame rate requested by clients are kept but the
maximum number of streams is reduced.
The frame rate of displayed videos is low.
N If the Built-in Viewer is in use, check the Built-
in Viewer settings.
If the network has a narrow bandwidth, the frame
rate will be limited.
If you set the video distribution setting to "Client
Number" and if the number of streaming requests
increases, the images are distributed at a frame
rate lower than the preset rate.
If the distribution capability is exceeded, images
are distributed at the lower frame rate so that the
upper quantity limit of distribution data is not
exceeded.
A white zone appears in the Built-in Viewer.
If you set up Internet Explorer as follows, some
Internet Explorer graphics may not appear and
will be left white on some computers.

If you select -[Appearance and
Personalization]-[Display]-[Make text and
other items larger or smaller] and select
"100% (default)", the normal graphic is
restored.
When 3D DNR is used, an afterimage
appears.
When you use 3-dimensional noise reduction, in
principle, an afterimage can appear if you shoot
a moving object, however it is not a camera
malfunction.
