Note
• When selecting [All] for the View Type, all images are displayed in 160 x 120
pixels resolution, and the Audio Control Bar is not displayed.
• 640 x 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 interval may
increase.
• If the refresh interval is too long, restrict the bandwidth on the Network page
(see page 51 and page 56). The refresh interval should improve.
• To reduce the data traffic, the video can be automatically changed to refreshing
still images on the General User page (see page 93).
• When viewing 4 cameras on the Multi-Camera page, you may need 3 to 4Mbps
bandwidth. If sufficient bandwidth is not available, the refresh interval may
increase.
When an image is not displayed on the Multi-Camera page
• Confirm that the global I P address is specified correctly for each camera an d
that each camera is connected to the Internet. For Internet access, local IP
addresses (e.g. 192.168.0.253) cannot be used. (see page 11 of
Troubleshooting on the CD-ROM).
• Confirm the settings on the Multi-Camera Setup page (see page 148).
• Confirm that the web browser is not accessing a proxy server (see page 186).
When setting [Do not permit access from guest users] or [Permit access from guest users (mobile only)] on the Security: Administrator page
• An authentication window is displayed when accessing the camera. Enter the
administrator's or the general user's user name and password.
• When you view images from several cameras on the Multi-Camera page, an
authentication window is displayed for each camera that has security settings
enabled. Enter the administrator's or general user's user name and password
registered for each camera.
Using the zoom feature on the Multi-Camera page
• The optical zoom is not available when viewing the Multi-Camera page,
however, a 10x digital zoom is available. You can zoom in and out using the
mouse or scroll wheel (see page 26).
• The zoom depth (x1.0—x10.0) is displayed while zooming.
• As the magnification increases, the image quality decreases.
