IP Cameras

The first IP camera was released in 1996 by Axis Communications. It used a custom web server internal to the camera.

In late 1999, they started using embedded Linux to operate their cameras. Axis also released documentation for their low-level API called "VAPIX" which builds on the open standards of HTTP and RTSP.

This open architecture was intended to encourage third-party software manufacturers to develop compatible management and recording software.

As with digital still cameras, the resolution of IP cameras has increased with time. Megapixel IP CCTV cameras are now available at resolutions of 1, 2, 3, 5 and even 11 megapixels. Today there are many manufacturers of IP cameras.

IP surveillance equipment vendors include both specialized digital imaging equipment manufacturers and larger manufacturers that are active in consumer, broadcast, and security video.
