Network Camera Technology

A network camera can be described as a camera and computer combined into
one unit. It connects directly to the network as any other network device.
A network camera has its own IP address and built-in computing functions to
handle network communication.
Everything needed for viewing images over the network is built into the
unit. A network camera has built-in software for a Web server, FTP server,
FTP client and e-mail client. Advanced cameras have the ability to detect motion,
produce two-way audio, and have digital inputs and outputs. Digital outputs
enable you to remotely, or automatically, trigger alarms, turn lights off/on,
or produce an audio warning to alert intruders that they are being filmed and
should leave the premises. Digital inputs that are connected to alarm devices
or sensors can, for instance, be used to trigger transmission of images to a
select destination for recording, or request that email alerts or SMS
notification be sent, for example, to a mobile phone or PDA.
