Fixed dome cameras essentially consist of a fixed camera pre-installed in a small dome housing. The camera can be easily directed to point in any direction. Its main benefit lies in its discreet, non-obtrusive design, as well as in the fact that it is hard to see in which direction the camera is pointing.

Fixed box camera with a body and a lens represent the traditional camera type. In some applications it is advantageous not to hide the fact that there are cameras. If this is the case then a fixed camera represents the best choice, since the camera is clearly visible, as is the direction in which it is pointing.

Another advantage is that most fixed cameras have exchangeable lenses of C/CS type. This allow flexible tuning of zoom and focus. For further protection fixed cameras can be installed in housings designed for indoor or outdoor installation.

Pan Tilt Zoom (PTZ) cameras have the obvious benefit of being able to pan, tilt and zoom either manually or automatically. For manual operation, a PTZ camera can, for example, be used to follow a person in a retail store. This is now also available with Object Tracking PTZ’s which automatically follows a moving object.

PTZ cameras can be used indoor or outdoor. Some PTZ cameras have full 360 degrees pan, and are made for continuous automatic operation.

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.

Network Cameras incorporating onboard processors and web server software. These Network Cameras can be connected directly to existing IP networks, eliminating the need for separate and expensive coaxial cable networks. Images can be viewed and cameras managed from anywhere via a web browser, plus any hard disk on the network can be set up to record the video output.

Though Network Cameras are getting more and more popular they are still more expensive when comparing with analog cameras.

Another important factor when considering if you should use a Network Camera or Analog Camera is the bandwidth capacity of the network. Most IP cameras are consuming enormous amount of bandwidth and can significantly slow down a small size home/office network.
