Symptom Multicast images do not play. The frame rate of displayed videos is low. A white zone appears in the Built-in Viewer. When 3D DNR is used, an afterimage appears. Possible Causes and Actions Taken ● Start manual multicast streaming from the [Multicast] page of the camera. ● When you receive multicast streaming using the Built-in Viewer, check to see that multicast address and port number matches between the [Multicast] page of camera and the Built-in Viewer settings. Also, use the multicast streaming on the network supporting the IGMPv2. ● Multicast streaming may be blocked by the Windows 7 Firewalls. In that case, you can go through the firewalls as follows. A Select [Start] - [Control Panel] - [System and Security]. B Open [Check firewall status] under [Windows Firewall]. C Open the [Advanced] menu and select [Inbound Rules] - [New Rule]. D In [New Inbound Rule Wizard], select "port" in [Rule type]. E In [Protocols and Ports], enter the port number for "Specific local ports". F Selects "Allow the connection" in [Actions]. G Selects applicable conditions in [Profile]. H Register an arbitrary character string for the "Name" in [Name]. ● When you are using the Built-in Viewer, check the 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 (A Page 5) is exceeded, images are distributed at the lower frame rate so that the upper quantity limit of distribution data is not exceeded. ● If you set up Internet Explorer as follows, some Internet Explorer graphics may not appear and will be left white on some computers. In such a case, you can display Internet Explorer graphics normally by selecting as follows. If you select [Start] - [Control Panel] - [Appearance and Personalization] - [Display] - [Make text and other items larger or smaller] and select "100% (default)", the normal drawing will start. 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.

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 (
A
Page 5) is
exceeded, images are distributed at the lower
frame rate so that the upper quantity limit of
distribution data is not exceeded.

If you select [Start] - [Control Panel] - [Appearance
and Personalization] - [Display] - [Make text and
other items larger or smaller] and select "100%
(default)", the normal drawing will start.

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.
