1. A method of operating a video system to detect fraudulent return transactions, the method comprising:
receiving an indication of a return transaction from a point of sale system, wherein the indication of the return transaction indicates a time when the return transaction occurred; receiving video data of an area proximate to the point of sale system captured at the time when the return transaction occurred; processing, by a processor, the video data to determine whether a first person is located in a return area and whether a second person is located proximate to the point of sale system; and determining, by the processor, whether the return transaction is legitimate or fraudulent based on whether the first person is located in the return area and whether the second person is located proximate to the point of sale system; wherein determining whether the return transaction is legitimate or fraudulent based on whether the first person is located in the return area and whether the second person is located proximate to the point of sale system comprises flagging, by the processor, the return transaction as potentially fraudulent when the first person is located in the return area, the second person is located proximate to the different point of sale system, and a third person is located proximate to the point of sale system. |
