if the other cameras do not support the overlay feature.

The audio controls displayed for other cameras depend on the audio features supported by the other cameras.

If the camera does not support pan and tilt features, this feature is not available.
Note
•
If a camera configured for the multi camera page is configured to not allow access from guest users,
an authentication dialog will be displayed for that camera. You will need to enter a valid user name and
password in order to view images from that camera.
•
The default settings for [Refresh Rate] and [Resolution] that are used each time the multi camera page
is accessed can be changed (see Page 110).
•
If a camera displayed on the multi camera page is configured to not allow general users or guest users
to access certain features (audio, pan/tilt, etc.), those features are not available and their corresponding
buttons or controls will not be displayed.
•
When [16 Screens] is selected as the number of cameras displayed, all images are displayed in
192
´
144 pixel resolution, images are displayed as still images, and the audio controls are not
displayed.
•
640
´
480 pixel images cannot be displayed on the multi camera page.
•
When viewing video images, we recommend connecting the cameras using an Ethernet switching hub
instead of a repeater hub to improve image refresh rate.
•
As a general guideline, about 3 to 4 Mbps of bandwidth are required to display 4 camera images. If
you do not have enough bandwidth, the refresh rate may decrease.
•
The image refresh rate may vary depending on network conditions, PC performance, the number of
people accessing the cameras, and the type of objects being viewed.
•
When the refresh rate is too slow, you may be able to improve the refresh rate by limiting the bandwidth
(see Page 82 or Page 133).
•
To reduce data traffic, you can configure the camera to automatically switch from displaying video
images to still images. Set the [Video Display Time] for general users (see Page 104) and for guest
users (see Page 107).
•
Image quality for MJPEG and still images cannot be changed directly on the multi camera page. This
setting is determined on the [Image Display] page (see Page 110).
•
MPEG-4 images displayed on the multi camera page are streamed using the HTTP protocol.
When a camera image is not displayed
•
Confirm the settings on the multi camera setup page (see Page 113).
•
When configuring cameras for the multi camera page, make sure that the cameras you want to access
from the Internet have been registered to this camera using their global IP addresses. For Internet access,
local IP addresses (such as 192.168.xxx.xxx) cannot be used.
