  4. Methods To setup a WebCam: • Client Pull • Server Push

  5. Methods to Setup a WebCam: Client Pull • Client pull method uses single snapshots of whatever the WebCam points to. • Process: • Web Camera takes snap and saves into JPEG File (e.g., CAM.JPG) • Simple html page served from WebServer, loads CAM.JPG on client request • (e.g. <img src=“CAM.JPG”> Remote Web Surfer Corporate LAN CAMERA -- PnP/Video/Digital Camera Computer Connected to Web Cam Computer Connected to Web Cam ISP hosted Web-Server with Video-Picture Serving Software

  7. Easy to setup. Doesn’t take much bandwidth. Works perfectly for dial-up style internet connections. Won’t be able to serve video feeds with this method. Relatively more cumbersome. Requires high bandwidth connection. Doesn't work good with Dial-up style internet connection. Will be able to view real-time video streams. Only most recent browser versions support this method. Advantages/Disadvantages of Methods Client Pull Server Push

  8. Important Considerations • Image Size: • Larger image will take more time to load, but resolution can be good. • Compromise should be based on bandwidth and clarity • Refresh Rate: • Higher refresh rate takes more bandwidth, but picture may look more connected • Compromise is based on bandwidth and continuity. • A reasonably user-accessible image size can be 320x240 for a refresh rate of 20-30 seconds (28k Modem)
