The entire process takes about 90 seconds. 15 minutes later the process repeats itself. The camera position is fixed and the lens does not zoom. To install a camera with those capabilities would require an investment many times the cost of the current camera and would create a number of other complications.

Several things can prevent images from being uploaded to the Internet.
The most likely reason is that the computer was unable to connect to the Internet for the last upload. The software will try 3 times and then wait for the next capture. If busy signals or other problems are encountered an image may not be transferred. Another reason could be that image uploads were suspended while system maintenance is being performed. With some browsers you have to hold the Shift key down while clicking on Reload to load a fresh image.
