The Warp Expo West WebCam

Saturday, September 18, 1999

Welcome to The Warp Expo West WebCam,
courtesy of Demand Systems and Tim Katz.

The image you see will update as often as your bandwidth and the overall system bandwidth will permit.

The WebCam is an Axis 200+ Camera/Server, supplied by Demand Systems. Engineering was done by Tim Katz of Demand Systems. The idea of having a WebCam at Warp Expo West was Tim's.

For the curious:

• The WebCam captures a color image and feeds it directly into the network. It has its own IP address and no intermediate computer or server is required.

• The image is supplied to HTML pages via push technology, and only requires a single IMG tag in the HTML code (Microsoft Internet Explorer does not support server push).

• The image is captured with a 768x582 CCD and is 24-bit color. The image you see here is resized by the camera from the captured original.

• The camera can update the image six times per second. The image is updated each time one of the connected users' browsers automatically requests a new image - each request is made as soon as the previous image is completely received, hence the system bandwidth typically is the limiting factor for fast image updates.

• The camera supports up to five simultaneous server push users, one or more of which may be relay points supplying many other users. If more than five users are connected to the camera, the first five receive the updating webcam image and the rest receive a single still image.
