A Network Camera is a camera and a computer combined in one device. Its components include the lens, image sensor, processors and memory and their purpose is to capture and analyze video recordings, process images and other network functions. A Network Camera, also called an IP camera, uses the memory to store and file the computer program or software it uses as well as the recording of video sequences.There are different kinds of a Network Camera and it is quite useful for those who are interested to use this device to be familiar with its functions to know which one is best for their area. A wired Network Camera is still preferred by some businesses due to its added security, its installation being inside walls or ceilings to hide the wires. It is also a little difficult for a potential hacker to get inside the system since this kind of Network Camera requires a physical connection to the network itself. One disadvantage of this kind is the time and cost it takes to set up the system since it needs major work on the walls, especially if a building or a home is not equipped to handle this kind of security.
Next kind is the wireless Network Camera gets rid of the cost that a user incurs with the purchase of cables or power sources and the time it takes to install the system is relatively short and easy. This device allows a little more flexibility that is often needed for homes and some businesses that cannot invest in a wired system. A wireless Network Camera is usually small in size, making it conspicuous and easy to hide among the items at home or in the office while larger ones are most often used for outdoors. Although quite handy, wireless networks are prone to interference by other sources and it can also be captured by people other than the authorized users.
Another type of a Network Camera is one that can be monitored remotely. The system must be connected to a broadband internet to start the video feed. Most of these come with a software CD that users can easily install and can be viewed using another computer. PDA and smart phone devices can also be linked to support viewing of the feed by using the apps on these units. A remote-monitored Network Camera is often triggered by motion sensors and notifies the users thru email.
