Abstract

An automated interactive surveillance device provides passive infrared surveillance of a predetermined area to determine if an intruder enters the area. When the passive infrared detectors detect such an intruder, the device acts to aim a camera and ultrasonic rangefinder in the appropriate direction. The rangefinder determines the precise distance from the device to the intruder, whereupon the camera is accurately focused, the focal length adjusted for a relatively narrow field of view providing good resolution at the selected distance, and the angular elevation of the camera is adjusted appropriately. The passive infrared detectors may cooperate with a program to determine an approximate size for the detected intruder, based upon the amount of heat detected and the range determined by the ultrasonic rangefinder, to thus determine whether or not a human threat exists. The device may be elevated, with programming considering camera height, range to the intruder, and amount of heat detected to determine the approximate height of the intruder and aim the camera accordingly for a high resolution facial shot. One or more devices as needed may be connected to a remote monitoring site.
