A video camera 10 is attached to a computer 12 having image processing facilities at a first location. The computer is also connected via a network 16 to a second remote computer. The image from the video camera is processed by the first computer, and then transmitted over the network to the second computer for display on a screen 22 where it is monitored by a user 24. The user 24 at the second computer can define regions of interest within the field of view of the video camera, and transmit information defining these regions back to the first computer. The first computer can then use this information to discard those regions of the field of view not selected, leaving only the selected regions to be transmitted to the remote computer, or further processed (eg for motion detection analysis). <IMAGE>
