Abstract

An anti-crime security system which provides an entrance and an exit to an establishment, wherein the entrance and exit define an enclosed area, provides sensors to monitor ingress and egress through the enclosed area, and monitors activity in the enclosed area and controls access to the establishment based on the ingress, egress, and activity monitored by the sensors.

Claims

1. An anti-crime security system, comprising:

access means for providing an entrance and an exit to an establishment and for defining an enclosed area;

sensor means for monitoring ingress and egress of a perpetrator through said access means and conditions within said establishment; and

central processing means for receiving input from said sensor means regarding the ingress and egress of the perpetrator and the conditions within said establishment and for controlling said access means such that when the perpetrator is inside the establishment and then a warning status is established, the perpetrator must reenter the enclosed area in order to exit the establishment, wherein the enclosed area is bounded by inner and outer doors which are automatically locked when the perpetrator reenters the enclosed area, whereupon an operator of said anti-crime security system controls a locking mechanism of the inner and outer doors, and the perpetrator cannot exit the enclosed area if a control panel of said anti-crime security system is disabled or the operator of said anti-crime security system is disabled or killed.

2. The anti-crime security system of claim 1, said access means including a double-door system including the inner door and outer door, which with two parallel sidewalls, define said enclosed area.

3. The anti-crime security system of claim 2, wherein said central processing means controls said access means such that said inner door and said outer door cannot be unlocked simultaneously.

4. The anti-crime security system of claim 1, said sensor means including,

person detecting means for detecting a person in said enclosed area;

and

metal detecting means for detecting a metal object in said enclosed area.

5. The anti-crime security system of claim 4, wherein, when said metal detecting means detects the metal object, said central processing means activates an emergency alarm and places said security system in a warning status.

6. The anti-crime security system of claim 5, wherein when said central processing means places said security system in the warning status, the warning status may only be deactivated by subsequent detection of the metal object by said metal detecting means.

7. The anti-crime security system of claim 4, said person detecting means including a tread switch and a photosensor.

8. The anti-crime security system of claim 1, wherein the establishment is a grocery store or a convenience store.

9. The anti-crime security system of claim 1, said central processing means operating in a plurality of operating modes, which vary in degree of security provided and operator intervention required.

10. The anti-crime security system of claim 9, wherein said central processing means places said security system in the warning status from any of said plurality of operating modes, when any one of a plurality of conditions are detected.

11. The anti-crime security system of claim 10, wherein said plurality of conditions include activation of an emergency key, activation of an audio sensor, and a crash door opening.

12. The anti-crime security system of claim 11, wherein the audio sensor is activated by a gun shot.

13. The anti-crime security system of claim 10, wherein the warning status may be deactivated if a person is detected in said enclosed area.

14. The anti-crime security system of claim 1, wherein said central processing means may be accessed only with proper identification.

15. The anti-crime security system of claim 14, wherein the proper identification includes one of a password and an authorized finger print.

16. The anti-crime security system of claim 15, wherein the password depends partly or completely on a system time clock.

17. The anti-crime security system of claim 1, said security system further comprising:

operator annunciator means for generating an audible signal to an operator of said security system;

emergency annunciator means for generating an audio signal, audible throughout the establishment; and

telephone interface means for contacting an external party when an external signal is generated by said central processing means.

18. The anti-crime security system of claim 1, said security system further comprising:

fire detection means for disabling said central processing means and said access means if a fire is detected in said establishment.

19. The anti-crime security system of claim 1, said central processing means including a central processing unit.

20. An anti-crime security system for an establishment, comprising:

access means for providing an entrance and an exit to the establishment and for defining an enclosed area, wherein the enclosed area is bounded by an inner door and an outer door; and

central processing means which operates in a plurality of operating modes, each automatically correlated with different degrees of traffic flow into the establishment and thereby providing different degrees of security for the establishment;

wherein the plurality of operating modes are set to a time schedule identified by an operator of said anti-crime security system to control said access means, in response to traffic flow during a time of day, wherein the plurality of operating modes include a first mode wherein either or both of the inner door and the outer door can be opened;

a second mode wherein one door cannot be opened unless the other door is closed and locked;

a third mode wherein the inner door cannot be opened when a sensor inside said enclosed area detects a dangerous object that is being brought into the establishment; and

a fourth mode wherein either the inner door or the outer door is locked and can be opened only with intervention by the operator;

wherein said central processing means operates in only one of the plurality of operating modes at any given time.
