Abstract: A method of taking an aerial survey maps boundaries of a first image and a second image from a first plane to a second plane to determine boundaries of an output image in the second plane. For a plurality of pixels in the output image, the method determines a corresponding pixel of either the first image or second image in the first plane.

Abstract: A control system for use with one or more video surveillance cameras forming a video surveillance system. The control system includes a video database module wherein a database entry includes at least one sensor condition defining an alarm state for each camera. Additionally, there is an alarm condition module that receives one or more sensor signals from one or more sensors associated with a camera and retrieves the sensor condition defining an alarm state for the camera. The alarm condition module outputs an alarm signal if the alarm condition module determines that the one or more sensor signals meets the one or more sensor conditions. The control system is modular and may be distributed in a network environment. The control system also monitors the network bandwidth and can adjust the throughput of digital data representing the digital images in order to avoid any bandwidth limitations.
