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.

Claims

1. A surveillance system for transaction stations comprising:

a television camera for developing frames of video signals representative of transactions performed by a human operator at a transaction station;

means including at least one operator-controlled device for developing digital electronic signals representing data entered by said operator at said transaction station about said transactions concurrently with the development of said video frames;

a video display device for visually displaying image frames of said transactions corresponding to and from associated frames of composite signals;

and means for generating a set of video character signals from said digital data signals of each of said transactions and for forming each of said frames of composite signals from one of said frames of video signals and a set of said character signals of the same transaction in a certain relation so that the associated character images are positioned on said display device in a certain location with relation to the associated image frames of said transaction.

2. A surveillance system as recited in claim 1 and further comprising:

computer means responsive to said digital data signals representative of said transactions for selecting for display associated ones of said frames of video signals in accordance with preset selection criteria.

3. A surveillance system as recited in claim 2 and further comprising means for recording said digital data signals in association with said frames of video signals.

4. A surveillance system as recited in claim 1 wherein said television camera is operative for concurrently developing frames of video signals individually representative of operator performed transactions at a plurality of transaction stations;

said digital data signal developing means includes a plurality of said operator-controlled devices individually associated with said transaction stations,

and said generating means includes means for generating video character signals for each of said devices and for display of video characters in relation to the image of the associated one of said transaction stations.

5. A surveillance system for transaction stations comprising:

a television camera for developing frames of video signals representative of transactions performed by a human operator at a transaction station;

means including at least one operator-controlled device for developing digital electronic signals representing data entered by said operator at said transaction station about said transactions concurrently with the development of said video frames;

a video display device for visually displaying image frames of said transactions;

and means operative in accordance with said digital data signals and certain preset criteria signals for selecting associated ones of said frames of video signals for display by said display device.

6. A surveillance system as recited in claim 5 and further comprising means including a video recorder for recording the selected ones of said video signal frames.

7. A surveillance system for transaction stations comprising:

a television camera for developing frames of video signals representative of transactions performed by a human operator at a transaction station;

means including at least one operator-controlled device for developing digital electronic signals representing data entered by said operator at said transaction station about said transactions concurrently with the development of said video frames;

a video recording device for recording image frames of said transactions;

and means operative in response to said digital data signals for selecting associated ones of said frames of video signals and for controlling the recording thereof by said recording device to produce an edited record of video frames.

8. A surveillance system as recited in claim 7 and further comprising means for recording edit-identification signals along with the associated video frames.

9. A surveillance system as recited in claim 8 and further comprising a video display device, and means responsive to said edit identification signals for controlling the display by said display device of the associated ones of said frames of video signals.

10. A surveillance system for transaction stations comprising:

a television camera for developing frames of video signals representative of transactions performed by a human operator at a transaction station;

means including at least one operator-controlled device for developing digital electronic signals representing data entered by said operator at said transaction station about said transactions concurrently with the development of said video frames;

a video display device for visually displaying image frames of said transactions;

means including a video recording device for recording image frames of said transactions and said digital data signals associated therewith;

and means operative in accordance with said recorded digital data signals and certain preset criteria signals for selecting associated ones for said recorded image frames for display by said display device.
