<ul><li>IP CAMERA </li></ul><ul><li>IP cameras are Closed-circuit television (CCTV) cameras that use Internet Protocol to transmit image data and control signals over a Fast Ethernet link </li></ul><ul><li>Also known as Network Cameras </li></ul>
HISTORY 1996 - The first IP camera was released by Axis Communication late 1999 - they started using embedded Linux to operate their cameras Mega pixel IP CCTV cameras are now available at resolutions of 1, 2, 3, 5 and even 11 mega pixels.
APPLICATION Security surveillance for Banks, Shops, Offices, Warehouses etc. Remote monitoring of the house, daycare or schools
<ul><li>GREATER FUNCTIONALITY </li></ul><ul><li>Wireless allows the camera to be placed just about anywhere. </li></ul><ul><li>No limit on resolution inherent in standard analog video formats. Mega pixel cameras can far exceed image detail from conventional CCTV cameras. </li></ul>
<ul><li>Password lockout of unauthorized personnel to prevent viewing images or altering the camera configuration. </li></ul><ul><li>Support for different streaming media and compression formats to relieve transmission bandwidth and data storage requirements. </li></ul><ul><li>Remote configuration, diagnostics, and maintenance </li></ul>
<ul><li>DISADVANTAGES </li></ul><ul><li>Higher initial cost per camera. </li></ul><ul><li>High network bandwidth requirements: a typical CCTV camera with resolution of 640x480 pixels and 10 frames per second (10 frame/s) in MJPEG mode requires about 3 Mbit/s. </li></ul>
<ul><li>Technical barrier. Installation for IP Camera required a series of complicated network setting including IP address, DDNS, router setting and port. This is very difficult for most users to do alone, without help from an IT technician. </li></ul><ul><li>Lower dynamic range - i.e. reduced ability to cope with low light and high contrast scenes </li></ul>
