Network ip security

 and which are different analogue closed circuit television cameras can send and receive the data through computer or internet. Though many cameras that do this are webcams the term IP camera is frequently useful only to those used for the security purpose. The initial centralized camera was introduced in 1996 by Axis communications. It was known as Axis Net eye 200 and was introduced by the group of Martin Green and Carl Axel. It used a custom web server inside to the camera. In the late 1999 the organization started using fixed Linux to operate their camera. The initial camera was introduced in 1999 by Robotics. IP cameras are accessible at decree from 0.3 to 11 mega pixels. In the customer TV trade in the early on 21st century there has been a move towards high description videos.

TYPES OF IP CAMERAS

There are basically two types of IP cameras.
•  Centralized cameras they require a central network video recorder to grip the recording, alarm and video management.
•  Decentralized cameras they do not require a central network video recorder as the camera has recording ability built in and can thus record directly to storage media digital.

Such as hard disk drives, flash drives, and network storage attached.

ADVANTAGES
•  Two way audio through a single network. Cable allows its users to communicate with what they are watching.
•  High image decree IP cameras have a decree of high megapixels and HDTV image quality at per second 30 frames.
•  Flexibility IP cameras can rotate around everywhere on an IP networking.
•  Distributed aptitude with IP cameras can be located in cameras they allowing in analytics solutions.
•  Transmission of command of pan, tilt, zoom cameras through only one wire.
•  Authentication and encryption IP cameras give safe and secure data transmission through authentication and encryption methods such as WPA, AES and WEP.
•  Remote accessibility live video from selected camera can be seen from any computer.
•  Cost benefit for large security systems. Research shows that for system with not more than 16 cameras analogue devices are very cheaper from 16 and 32 they are equal.
•  IP cameras are able to purpose on a wireless network. First design has to be done via a router after the IP camera is installed it can be used easily.
