A client-server arrangement for camera viewing using digital cameras across a computer network. A camera server controls a motorized gimbal to affect camera viewing angle changes according to signals from a client computer which is equipped with an eye movement tracking system. Movements of the viewer's eyes result in changes in viewing angle of the remote cameras. Prior to transmission, the server divides the original full-resolution image into a foveal area and a peripheral area. The peripheral area data is reduced in resolution, thereby reducing the image data size, required transmission bandwidth, transmission size, and image update latency. Later, the full resolution data from the peripheral area of the image may be transmitted to the client machine so that the full image may be rendered in original full resolution.
