If your ISP/Access Provider uses a dynamic
system of assigning IP Addresses, you can still connect a Network IP
Camera by using a web based service. For details, visit

A Network IP
Camera is a stand-alone device which allows a user to view live, full motion
video from anywhere on a computer network, even over the Internet, using a
standard web-browser.

No, some network
cameras have an embedded OS (operating system) as well as an embedded Web server.
To be called a Network IP camera, the only requirement is that the camera connects
to the network, and not a computer - an embedded OS is what separates network cameras.

An IP Camera is a
true networking device containing an embedded OS (Operating System), supports
multiple users, and can be viewed using any web browser. It does not require
additional hardware to operate and therefore has the flexibility to be located
anywhere with a network connection. A web cam must be connected to a host
computer, supports only one user at a time, and cannot be shared on a network.
Only the host computer can access the web cam.

Cameras with an embedded OS communicated directly with the user, the
images or video is sent directly from the camera to the person
accessing the camera. A Network camera without an embedded OS must
rely on a third party server or a separate piece of software,
meaning the images/video is sent to the third party server, then the
user access the image from the third party server.

No,
you of course, can have a real, public, static IP address for each
camera, however, using just one static IP address for your router
and a virtual server or port forwarding scheme, you can use many
cameras with just one static IP and just about any router. Please
also note that the IP camera must have an adjustable web server port
(you must be able to change the web server port) to use multiple
cameras behind a router.

Can I use the camera
outside?
Some Network IP
Cameras are sturdy enough for outdoor use with a outdoor camera
enclosure.

What additional software
is required?
Networking IP Cameras with an embedded Operating System (OS) should
not need any additional software.

How does the built-in
motion detection work?
It
very simply compares what it sees now to what it saw in the last
frame and based on a sensitivity you select will trigger an event.
The event can be to send a email, to send a Image to a FTP server,
or to send a series of images (before and after the motion is
detected) to a email address or a FTP server-all with software built
into the camera, nothing else is required.

What is the maximum
length Ethernet cable I can use?
The
same topology limitations that apply to any 10/100 Ethernet card
apply, meaning the maximum segment length is 100 meters from
switch/hub to the camera.

How much digital video
can be stored on a normal 20-gigabyte hard drive?
Network IP Cameras equipped with a compression technology that can
store almost a month of continuous video on a 20-gigabyte hard
drive.

What is
Power-over-Ethernet (PoE)?
Power-over-Ethernet (PoE) or "Active Ethernet" eliminates the need
to run power to devices on a wired LAN. Using Power-over-Ethernet,
installers need to run only a single CAT5 Ethernet cable that
carries both power and data to each device. This allows greater
flexibility and significantly decreases installation costs in many
cases.

Can Network IP Cameras
use different lenses?
Advanced Network IP Cameras utilize CS-mount lenses, which can
accommodate a variety of specialized lenses, such as wide-angle,
fish-eye or telephoto lenses.

What image sizes can be
viewed from Network IP Cameras?
Advanced Network IP Cameras use multiple pre-set image sizes that
typically include 160 x 120, 320 x 240 and 640 x 480 pixel image
sizes.

Can I view a Network IP
Camera from my PDA?
Network IP Cameras can now be viewed on most Windows CE, including
Pocket PC and Pocket PC 2002 devices, such as the Compaq iPAQ, HP
Jornada, Dell Axim, Casio Cassiopeia and many other devices.
