Claim One:
1. A method of calibrating a field of view of a sensor within an observable area, comprising the steps of: defining a reference image of a first observable area having at least one distinctive feature, said reference image defined by a first sensor placed at a base location; establishing a set of reference points relative to said first sensor that represent a location within said reference image of said at least one distinctive feature; placing a second sensor in a second observable area that is similar to said first observable area, said second sensor being placed in a location that generally corresponds in position to said base location; obtaining a test image of said second observable area, said test image obtained by said second sensor and depicting at least one distinctive feature present in said second observable area; and comparing said set of reference points to said at least one distinctive feature depicted in said test image in order to assess a relative accuracy in placement of said second sensor.
