Modem Applications

If a local network connection is not available at your chosen point of installation, you can
alternatively connect your AXIS 2120 to a V.90-compatible modem and quickly configure any
number of exciting applications using the Wizards; including:
• Viewing images in a fully custom-designed Web page over a Dial-up modem connection.
• Sequentially uploading images to an ISP (Internet Service Provider) over a dial-up modem
connection and publishing images to the whole Internet community.
• Uploading single or pre/post alarm image sequences to your ISP over a dial-up modem connec-
tion, when an alarm or time-based event occurs; and optionally, sending e-mail alerts containing
single images or Web links to pre/post alarm images stored by your ISP.
Important!
• Although the AXIS 2120 is compatible with most V.90-compliant modems, Axis does not undertake
any responsibility for V.90 modems that fail to work with the product.
• When the AXIS 2120 is dialing out it will obviously not be possible to dial-in to it. If you configure an
interval during which the camera will not be dialling out, this will allow you to dial-in and make any
necessary changes etc.
Configuration
All modem applications must initially be configured from a browser on a local computer. If
available you should always use an Ethernet network for this purpose, even if the actual application
will be using a modem. If there is no network available, you can instead use the supplied Null
Modem Cable to create a direct connection to the AXIS 2120 from the computer. This direct
connection is only intended as an alternative for the initial configuration of the modem application
when there is no network available. The Null Modem Cable should not be used for any other
purpose.
Note:
Once the Dial-up modem connection has been created and the AXIS 2120 is physically con-
nected to the modem, you can then dial-up your AXIS 2120 in exactly the same way as you
would to your ISP. The installer of the camera uses the Installation and Application Wizards to
establish the basic parameters for your application, and advanced users can then use the Adminis-
tration Tools to refine the application.
Picture Frequency for Modem Applications
When used with a modem, the speed of your communications link will normally determine the
image frequency in your browser. A standard image is normally transmitted in 2-5 seconds,
although optimal image frequency is achieved by buffering the video stream into internal memory
before uploading the recorded images to your ISP or Web server. This is the ideal solution for
remote applications connected to external security devices and which require a good flow of images
from alarm events.
