A target odor detection apparatus (100) and system configured to temporarily house one or more animate odor detectors (118) for screening air passed across odor emitters or conveyances that pass through the target odor detection apparatus. Various types of sensor technologies are incorporated in certain embodiments to provide consistent detection results by, inter alia, consistently interpreting trained signals from animate odor detectors (118). Various communication technologies are incorporated in certain embodiments to provide enhanced control over an apparatus or system located in multiple and, in some cases, very distant, geographic locations. A target odor detecting apparatus (316) and method including a rotatable door assembly (318) is disclosed for screening odor emitters for target odors. A screening zone (320) is defined within the rotatable door assembly (318) wherein air is moved to an observation room (326) for screening by an animate odor detector (118) to detect one or more target odors.
