A network camera has its own IP address. It is connected

to the network and has built-in software for a Web

server, FTP server, FTP client, e-mail client, etc. It can

even run customized scripts (small programs).

A real network camera does not need to be connected

to a PC. Note that many Web cameras and Internet

cameras, claiming to be network cameras, are in fact

simple PC cameras that require connection to a PC via

a USB or printer port connection. For these products, a

PC is needed for connection to the network.

Network cameras are equipped with digital inputs

and outputs. The digital inputs can be used to trigger

the transmission of images from the camera.

Digital outputs can be used for instance, to open a

door remotely, or to turn on a light inside a building

when viewing images remotely.

Network cameras with image buffers can save and

send the images which were collected before an alarm

occurred. See also Triggering Mechanisms on page 16.
