3.4.5 Browser Settings
Current browsers with activated
JavaScript
(Internet Explorer, Netscape, Mozilla,
Firefox, Safari, Konqueror, Opera, Camino, etc.) can show the camera's live images
without changing the default settings. Text-based browsers (e.g.
lynx
) cannot dis-
play the user interface and are
not suitable for operating the camera. A restrictive
configuration of a browser or operating system, however, will prevent certain cam-
era features from working properly and may even make working with the camera
impossible. This can also be caused by the selected security or browser cache set-
tings or if proxy servers are used.
You may experience problems in the following areas:
•
Popup Blocker:
Popups
are windows that display (mostly unwanted) win-
dows without user interaction (in this case, the web server of the MOBOTIX
camera creates these windows). While active popup blockers make sense
when surfing websites on the Internet, they may prevent individual windows
from being displayed when used together with a MOBOTIX camera. The
MOBOTIX camera creates individual popup windows in order to display
detailed information (e.g. the
Network Test Log window, see section 5.3, Con-
nection Test, in the Software Manual). Since popup blockers are available not
only in browsers but in plug-ins as well (e.g. in the Google toolbar), you need
to take care that this issue is resolved properly.
To circumvent this problem, you can either deactivate popup blockers in gen-
eral or you can enter the respective camera IP addresses or address ranges
in the
exception lists
of the popup blocker or browser (recommended).
•
Browser Cache:
Browsers store viewed pages locally in the
cache
of your
computer. This minimizes the transfer time and reduces bandwidth. There is,
however, a chance that you may see outdated information. When updating
the camera software, this can cause negative side effects.
To avoid this, it is recommended that you configure your browser cache so
that the cache contents are
automatically
compared to the contents of the
website every time you access a website. While the software is updated, it is
recommended that you either deactivate the cache or set it to its minimum
size.
•
Proxy Server:
Similar to browser caches,
proxy servers
(predominantly used
in larger networks) are used to temporarily store website files so that these
files can be sent to a browser without having to download them again.
When updating the camera software, for example, proxy servers can block
the entire process or parts of it.
If a proxy server is used in your local network, it is strongly recommended
that you enter the cameras' IP addresses (or a corresponding camera sub-
net) as
proxy exceptions
(see chapter 6,
Software Updates, in the Software
Manual).
