Abstract
This surveillance system employs a closed circuit television camera or cameras used in conjunction with an electronic cash register or registers employed at one or more point of sale stations. Combined images of transaction items viewed by a camera at a given station and transaction data (such as prices) rung up on the cash register at said station are presented on a television monitor. Signals for these combined images are also stored on video tape together with coded signals related to transaction data to achieve computerized editing.
