IP cameras are Closed-circuit television (CCTV) cameras that use Internet Protocol to transmit image data and control signals over a Fast Ethernet link
Also known as Network Cameras
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
NVR (Network Video Recorder)
Mega Pixel Cameras
Wireless allows the camera to be placed just about anywhere.
No limit on resolution inherent in standard analog video formats. Mega pixel cameras can far exceed image detail from conventional CCTV cameras.
Password lockout of unauthorized personnel to prevent viewing images or altering the camera configuration.
Support for different streaming media and compression formats to relieve transmission bandwidth and data storage requirements.
Remote configuration, diagnostics, and maintenance
Higher initial cost per camera.
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.
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.
Lower dynamic range - i.e. reduced ability to cope with low light and high contrast scenes
