Abstract: A system for detecting suboptimal performance of security check operations. The system may include a sensor operable to output sensor data indicative of physical characteristics of a security check environment, an output device, and a processing device comprising a processor and a memory. The security check environment may include at least one of a prohibited object detector, a human patron, an object carried by the human patron, and a human security officer. The processing device may be operable to: determine, based on the sensor data, that security check operations at the security check environment are being performed in a suboptimal manner; and in response to determining that the security check operations are being performed in a suboptimal manner, output alarm data to the output device to cause the output device to output an alarm signal indicative of the suboptimal manner in which the security check operations are being performed.
