An electronic article security system monitors articles sold by a retail store to detect shrinkage. The articles are tagged with RF-ID security tags. Each security tag has a unique or semi-unique serial number for identifying individual products. Transaction records generated from point-of-sale terminals in the store are sent to a remote computer. An interrogator and surveillance camera are positioned near the store exit. When an article having the RF-ID security tag is detected as passing through the store exit, the interrogator outputs a signal derived from the security tag. The output signal includes the security tag serial number. Also, the camera takes an image of the person moving the tagged article through the exit. The interrogator output signal is sent to the remote computer. The remote computer periodically compares the transaction records with the interrogator output signals to detect any discrepancies therebetween. The discrepancies are investigated by viewing the captured video images near the time of the discrepancies.
