For example, in the case of theft prevention at a construction site, when a worker enters a door through the first security antenna, the first antenna detection parameter (corresponding to the metal content) at the entrance of the worker is recorded after the worker is detected by the first face identification device and the first security antenna (such as a metal detector). When the worker goes out of work through the second security antenna, the second antenna detection parameter (equivalent to metal content) corresponding to the worker is detected again through the second security antenna, the difference value (equivalent to metal content difference) between the second antenna detection parameter and the first antenna detection parameter when the worker goes in and out is compared, if the difference value is larger than or equal to a preset difference value, the worker can be judged to have stealing behaviors of valuable commodities such as entrained steel bars, and the like, and therefore an alarm is triggered, otherwise, the worker is judged to have no stealing behaviors, and the alarm is not triggered. Compared with a single metal detector, the invention has the advantages that personnel entering the security place do not need to take off shoes, belts or glasses and other personal articles, and the invention can be applied even if the personnel entering the security place have unremovable metals such as artificial limbs and the like, thereby avoiding triggering alarm due to the unremovable metals such as artificial limbs and the like on the personnel, and further reducing the false alarm rate.

On the contrary, if a customer carries a commodity which is not bought, because the commodity is not processed by a lock opener or a demagnetizer (Deactivator), when the commodity which is not bought passes through the second security antenna, the second antenna detection parameter detected by the second security antenna is obviously greater than the first antenna detection parameter detected by the first security antenna when the customer enters the supermarket, and at the moment, the difference between the second antenna detection parameter and the first antenna detection parameter is greater than or equal to the preset difference, so that the customer which does not buy the bill can trigger an alarm. According to the embodiment of the invention, whether the customer steals or not is judged by comparing the signal amplitude values corresponding to the customers when entering and leaving, even if the detected second antenna corresponding to the customer has a larger detection parameter due to interference factors such as electromagnetic signals generated by portable electronic products, an alarm cannot be triggered, the false alarm rate is effectively reduced, and the shopping experience of the customer is improved.

In order to collect personal identification information of a person to be left and obtain a second antenna detection parameter corresponding to the person to be left, in an optional implementation manner, the person to be left specifically refers to a person who leaves the security place through the third security antenna; step S102 "receiving the personal identification information of the person to be away collected by the collection assembly, and obtaining the second antenna detection parameter received by the corresponding security antenna assembly", specifically includes:
when the fourth face recognition device captures the face of a person passing through the third security antenna and the third face recognition device captures the back shadow of the person, determining that the person is a person to be left;
and receiving the face information of the person to be departed, which is acquired by the fourth face identification device, and acquiring a second antenna detection parameter received by the corresponding third security antenna. Other structures and working principles of this embodiment are the same as those of the first embodiment, and are not described herein.
In the middle of the concrete implementation, the security protection place is equipped with the access & exit, third security protection antenna third face identification equipment with fourth face identification equipment locates the access & exit, the access & exit can supply personnel to pass in and out two face identification equipment towards the two directions of access & exit respectively of access & exit installation judge promptly for the personnel to get into when people's face is shot to one of them face identification equipment and another face identification equipment shoots the back shadow, otherwise then judge for the personnel to go out. The third security antenna provided by the embodiment of the invention can detect the signal amplitude of the person entering and exiting at the same entrance and exit, and does not need to independently arrange an exit and an entrance or arrange security antennas for the person entering and exiting respectively, thereby greatly reducing the cost.
For example, in the case of theft prevention at a building site, when a worker enters a door through the third security antenna, the first antenna detection parameter (corresponding to the metal content) at the entrance of the worker is recorded after the worker is detected through the third face recognition device, the fourth face recognition device and the first security antenna (such as a metal detector). When the worker goes out of work through the third security antenna, the second antenna detection parameter (equivalent to metal content) corresponding to the worker is detected again through the third security antenna, the difference value (equivalent to metal content difference) between the second antenna detection parameter and the first antenna detection parameter when the worker goes in and out is compared, if the difference value is larger than or equal to a preset difference value, the worker can be judged to have stealing behaviors of valuable commodities such as entrained steel bars, and the like, and therefore an alarm is triggered, otherwise, the worker is judged to have no stealing behaviors, and the alarm is not triggered. Compared with a single metal detector, the invention has the advantages that personnel entering the security place do not need to take off shoes, belts or glasses and other personal articles, and the invention can be applied even if the personnel entering the security place have unremovable metals such as artificial limbs and the like, thereby avoiding triggering alarm due to the unremovable metals such as artificial limbs and the like on the personnel, and further reducing the false alarm rate.

On the contrary, if a customer carries a commodity which is not bought, because the commodity is not processed by a lock opener or a demagnetizer (Deactivator), when the customer carries the commodity which is not bought and passes through the third security antenna, the second antenna detection parameter detected by the third security antenna is obviously greater than the first antenna detection parameter detected by the customer when the customer enters the supermarket, and at the moment, the difference value between the second antenna detection parameter and the first antenna detection parameter is greater than or equal to the preset difference value, so that the customer which does not buy the list can trigger an alarm. According to the embodiment of the invention, whether the customer steals or not is judged by comparing the signal amplitude values corresponding to the customers when entering and leaving, even if the detected second antenna corresponding to the customer has a larger detection parameter due to interference factors such as electromagnetic signals generated by portable electronic products, an alarm cannot be triggered, the false alarm rate is effectively reduced, and the shopping experience of the customer is improved.
