Note
The digital zoom feature and the Click to Center feature can be used for
video (Motion JPEG) only.
When selecting [All] for the View Type, all images are displayed in 160 ×
120 pixels resolution.
640 × 480-pixel images cannot be displayed on the Multi-Camera page.
When viewing video (Motion JPEG), we recommend using an Ethernet
switching hub instead of a repeater hub to prevent degradation in video
display.
Due to network congestion or the number of accesses, the refresh int erval
may increase.
If the refresh interval is too long, restrict the bandwidth on the Network
page (see page 48). The refresh interval should improve.
To reduce the data traffic, set up [Limit Continuous Motion JPEG] on the
Image Display page (see page 103). The video (Motion JPEG) can be
automatically changed to refreshing still images. Images of moving
subject are blurred or not displayed.
When viewing 4 cameras on the Multi-Camera page, you may need 3 to 4
Mbps bandwidth. If sufficient bandwidth is not available, the refresh
interval may increase.
The Click to Center feature can be used while using the digital zoom.
When an image is not disp layed on the Multi-Camera page
Confirm that the global IP address is specified correctly for each camera and
that each camera is connected to the Internet. For Internet access, local IP
addresses (192.168. .) cannot be used. (See page 11 of
Troubleshooting on the CD-ROM)
Confirm the settings on the Multi-Camera Setup page (see page 106).
Confirm that the web browser is not accessing a proxy server (see page 141).
