Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for performing access control, and more particularly to an access control device that allows text information to be directly superimposed on a live image.

[0002]

In recent years, various forms of safety and access control devices have been developed to monitor entry into monitored buildings and areas. An individual entering the building inserts an identification card or access card into the access reader at the entrance. Inserting the card also activates a pre-programmed video camera to expand the entrance area that the individual is trying to access. The video camera sends live footage to a device that monitors the individual attempting access. The surveillance device then displays a picture of the individual at the entrance. The footage may then also be recorded on a video cassette recorder (VCR) as well.

More specifically, when an individual inserts a card into an access reader, the reader can read the information on the card and store it optically, magnetically or mechanically. This information then makes it possible to determine whether the card is valid or invalid as well as the individual's name, identification code and other desirable information through an access controller such as a sensor panel. Determining whether the card is valid or invalid, thereby permitting or denying entry, is called the "access control result". The access control results and the individual's name, identification code, date, time, etc. are then sent to a printer that prints this data as a separate log.

[0004]

If the security staff wants to know who has entered or is about to enter the building effectively or ineffectively, such an access control device can be used to print log logs. It is necessary to re-examine the out and at the same time re-examine the video recorded on the videotape so as to correlate the observed video with the data. Therefore, it is inconvenient and difficult to match the video review and the log inspection.

[0005]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to view a live image together with text information describing an access control result on a display device, and at the same time record a live image on which text information is superimposed for later viewing. It is to provide an access control device that can be easily and conveniently operated.

Another object of the present invention is to provide an access control device having a simple design and being able to easily view and maintain text information along with an image.

An additional object of the present invention is the ability to trigger an alarm based on textual information associated with the access control results transmitted through a series of communication interface ports within the access controller or other data transmission device. There is to let.

According to the principles of the present invention, these and other objects are realized by an access control device. The access control device reads the information stored in the access card,
To allow or deny entry into the restricted area, it has an access controller that can determine whether the information stored on the access card matches the stored information stored in the access controller. A video camera is placed in the entrance area to the restricted area to capture live footage of the individuals attempting access. The access controller determines whether the card is valid or invalid and rewrites the information into an output with textual information through a series of communication interface ports or other data transmission devices that send data to the text overlay controller. The text superimposition controller directly superimposes text information describing the access control result on the video received from the video camera. The textual information and video are displayed on a video display device while being recorded on a videocassette recorder for later viewing.

First and second cards, such as a Sensormatic® card reader, model number, IRWS00, with first and second closed circuit televisions (CCTV) or video cameras 28 to monitor entry to identified doorways. A reader 12 is provided in the entrance area to a restricted area such as a building entrance. An individual entering the building inserts an access card (not shown) into one of the access card readers. Inserting the card will activate either the first or the second video camera depending on the access card reader used. Video switch 26 allows switching to either of the two cameras to view a particular entrance.

The card used in the access card reader 12 can have magnetic information embedded within a magnetic strip, for example, in preparation for various information to be stored on the card. Such information stored on the card includes
It can include personal identification number, facility code number, name, address, etc. This information, which is then read as a digital bitstream from the card reader 12, is provided by the Sensormatic® panel, model number, SPS4.
To the access control means, that is, the access controller 14. The access controller 14 compares the information from the card with the corresponding registration information stored in the storage device of the access controller 14 to determine if the information from the card matches the registration information. After that, the access controller 14 determines whether or not they match with each other.
I) Encode and rewrite the output with the textual information as a code string. This comparison determines whether the card used by the individual is valid or invalid and determines the access control result. The textual information, ie the ASCII code string, is also sent to the computer 20 through a series of communication interface ports 15.

A computer 20, such as an IBM® compatible computer, comprised of Sensormatic® AC500 software, receives textual information coming from several access controllers and stores the textual information. It can be displayed on the computer display device 22. The access controller 14 can control up to eight access card readers at a time and monitor at least one access controller. However, the access control device 1
The 0 is not limited to such a configuration and can include various configurations and components to provide a system for permitting or denying access to restricted areas. The printer 24 attached to the computer 20 not only determines the access control result by the access controller 14, but also prints out the information read from the access card.

The mouse 34 allows additional monitoring of the access control device 10 through security personnel. The user uses the mouse 34 to program the text superimposition controller 100 so as to identify a series of text information indicating a specific access control result. By programming the text overlay controller 100 to identify specific access control results, security personnel not only can view these results on the monitor (display) 30, but also You can also start the VCR for recording.

Such a program can be created by the user. That is, it can be done by using the mouse 34 to access the menu driven software program generated by the text overlay controller 100. To program the text overlay controller 100, the user clicks and operates the mouse 34 to view a series of menus displayed on the monitor 30. The first line of text in the window displayed on the surveillance device 30 is the inverted video or highlighted. By moving the mouse 34, the user can select the desired menu item. By selecting the desired menu item, the user may "alert" a particular access control result, such as DENIED INVALID or INVALID, to program the text overlay controller 100 in response to the particular access control result. Case ”.

For example, when an alarm event such as DENNIED INVALID occurs, text information "D
"ENIED INVALID" appears on the monitoring device 30,
It visually alerts security personnel. Further, the text superimposition controller 100 closes the alarm relay (relay) and starts recording the text information "DENIED INVALID" superimposed on the video signal from the camera 28 and the video signal from the camera 28, and attempts the "invalid" entry to the VCR It will be recorded in 32. In addition, the text superimposition controller 100 is
