A body warning system includes: a sensor 110, a recording unit 120 and an evaluation unit 130. The sensor 110 is trained to detect a potentially dangerous body 10. The recording unit 120 continuously stores detector data 111 generated by the sensor 110 for a predefined period of time. In the detector data 111 received in a pre-classification 131, the Evaluation Unit 130 detects a 10-body detection signal and compares it with a declaration threshold value,to generate a 10-body warning signal after a declaration threshold has been exceeded and, if the 133 warning signal is present in a 132 classification, to perform a 10-body verification based on a tracking; where the tracking includes an analysis of the stored detector data 121. If the body 10 is verified by classification 132 as such, or if the detection signal exceeds a higher threshold value,the evaluation unit 130 emits an alarm 140.
