The device information display configuration file can be a floor plan of each floor of the office or a three-dimensional image of the office. The third server 15 provides a monitoring interface according to the device information display profile and device configuration data. For example, the monitoring interface may be a graphical interface combined with device information display configuration files and device configuration data. Specifically, the monitoring interface can visually present the installation positions of the electronic devices 22 , 23 , 25 in the case. For example, according to the installation position of the office, the visual patterns are used as the electronic devices 22 , 23 , 25 and drawn at the corresponding positions in the map.

The monitoring interface displays the status of the electronic equipment 22, 23, 25 according to the equipment signal. For example, the monitoring interface can display the states of the electronic devices 22 , 23 , 25 in a visual form. Specifically, the monitoring interface can use different colors and/or patterns to display different states of the electronic devices 22 , 23 , 25 . For example, the monitoring interface has a name field and a status field of the electronic devices 22 , 23 , 25 . When the status column displays a green circle, it means that the corresponding electronic device 22, 23, 25 is turned on; when the status column displays a red cross, it indicates that the corresponding electronic device 22, 23, 25 is closed.

The second server 13 has a user database to verify the login authority of the administrator account and the user account. After being verified by the second server 13, the user can enter the third server 15 to use its services. Manager accounts are for security personnel and user accounts are for customers.

The third server 15 has a front end and a back end. In some embodiments, the front end and the back end can be implemented by web pages. After logging in the second server 13, the administrator account enters the backend to edit the device information display configuration file, such as adding, deleting, and/or modifying the device information display configuration file. The user account enters the front-end operation monitoring interface after logging in the second server 13 . In this way, customers (such as case guards) can operate the monitoring interface at any time, and security personnel can also remotely edit and maintain device information display configuration files without being limited by hardware devices. In some embodiments, after logging into the second server 13 and entering the third server 15, the second server 13 can use SSL encryption to encrypt the commands generated when the administrator account is edited, and encrypt the user account. Instructions generated during operation are encrypted. In this way, the risk of being stolen can be reduced.

In some embodiments, customer subscription data is associated with a user account. When the customer does not renew the security service, the security staff operates the first server 11 to disable the customer's subscription data. After the customer subscription information of the first server 11 is disabled, the second server 13 prohibits the user account login and enters the foreground of the third server 15 . That is to say, when the security service is subscribed, the customer can log in the second server 13 through the user account to enter the front end of the third server 15, and when the security service is not subscribed, the customer cannot log in to the third server 15 through the user account. The second server 13 cannot enter the front end of the third server 15 . In this way, it can be ensured that the customer's usage authority on the third server 15 is updated in real time, so as to save resources.

In some embodiments, the front end has a login QR code. The second server 13 obtains the login information after the terminal device scans the login QR code. For example, the customer's terminal device is installed with an application program that cooperates with the second server 13. The application program scans the login QR code through the image capture device (such as a camera) of the terminal device to generate a login message, and sends the login message through the network. route to the second server 13. The second server 13 verifies the user account according to the user database and login information. In some embodiments, the login QR code is, for example, a QR code.

In some embodiments, the second server 13 stores a first session ID (session ID). In some embodiments, the first chat ID may be stored in a user database. When the user account logs into the second server 13 and enters the front end of the third server 15 , the third server 15 generates a second chat ID and transmits the second chat ID to the second server 13 . The second server 13 judges whether to The user account is logged out and cannot enter the front end. For example, the second server 13 compares whether the first chat ID matches the second chat ID. When the first conversation identification code matches the second conversation identification code, it means that the customer has not logged in from another place through the user account and entered the foreground. At this time, the second server 13 maintains the login of the user account. When the first conversation identification code does not match the second conversation identification code, it means that the customer logs in through the user account in another place and enters the front end. At this time, the second server 13 logs out the user account and cannot enter the front end. In this way, it can be ensured that customers cannot log in from different places and enter the front end to operate the monitoring interface, thereby reducing the risk of being stolen.

In some embodiments, after the user logins into the foreground and the monitoring interface is not operated for a period of time, the second server 13 logs out the user's account so that the foreground cannot be entered. That is to say, after the monitoring interface is idle for a period of time, the user account can be logged out to save energy and the risk of being stolen.

In some embodiments, after the administrator account logs in and enters the backend, the second server 13 (such as a timer of the second server 13) accumulates the login time, and when the login time is greater than the time threshold, the second server 13 Make the administrator account log out and cannot enter the backend. In this way, it is ensured that the editing performed by the security personnel after logging into the second server 13 with the administrator account and entering the backend of the third server 15 is completed within a limited time. That is, the update of the device information display profile will not be delayed.

In some embodiments, the monitoring interface includes a security setting interface, a cancel interface, an abnormal notification interface, a device startup and shutdown interface, a real-time video interface, and an abnormal video interface. The security setting interface is used to set the security status of the security system 20 as enabled or disabled. For example, the security setting interface has a security activation button and a security release button. After the customer can log in the second server 13 with the user account and enter the front end of the third server 15, click the security enable button to set The security state of the security host 21 of the security system 20 is enabled, or the security release button is clicked to set the security state of the security host 21 of the security system 20 to be released. Specifically, after clicking the security activation button, the third server 15 transmits the first operation signal to the security host 21 of the security system 20 through the second server 13, so that the security host 21 will respond to the first operation signal. Status is set to enabled. After clicking the security release button, the third server 15 transmits the second operation signal to the security host 21 of the security system 20 through the second server 13, so that the security host 21 responds to the second operation signal and then sets the security status as release state. When the security system 20 is activated and abnormal behavior occurs in the crime scene, the electronic devices 22 , 23 , 25 can send out alarms and generate device signals indicating the abnormal state. When the security system 20 is in the disengaged state, when an abnormal behavior occurs in the case, although the electronic devices 22, 23, 25 detect the abnormal behavior, the security host 21 does not send an alarm.

The abnormal notification interface responds to the abnormal status of the device signal, and sends out abnormal notifications to remind customers that abnormal behaviors are currently occurring in the case. In some embodiments, the electronic devices 22, 23, and 25 include cameras as an example. If an intrusion or abnormal event occurs in the crime scene, the abnormal notification interface will pop up the real-time images of all the cameras in the area and issue an abnormal warning sound until the security personnel at the crime scene turn off the abnormal warning sound. In some embodiments, when the electronic device 22 , 23 , 25 sends out an alarm, the abnormality notification interface actively pops up a reminder, and guides the screen of the abnormality notification interface to what is the cause of the alarm. In some embodiments, when the electronic device 22 , 23 , 25 sends out an alarm, the abnormal notification interface actively brings out the real-time images of the cameras in the area to monitor the alarm status in real time. In some embodiments, when the electronic device 22, 23, 25 sends out an alarm, the abnormality notification interface emits an abnormality warning sound, until the guard at the crime scene clicks the confirmation button on the abnormality notification interface and stops playing, so as to ensure that someone knows when the alarm occurs. In some embodiments, documented When an intrusion or an abnormal event occurs in the field, the abnormal notification interface will display which electronic device 22, 23, 25 is abnormal (that is, which electronic device 22, 23, 25 is currently generating a device signal indicating an abnormal state).

The device opening and closing interface is used to control the opening or closing of the electronic equipment 22 , 23 , 25 . For example, the device opening and closing interface has multiple opening buttons and multiple closing buttons, and each electronic device 22 , 23 , 25 corresponds to one opening button and one closing button respectively. After the customer can log in to the second server 13 with a user account and enter the front end of the third server 15, click the open button to open the corresponding electronic device 22, 23, 25, or click the close button to open the corresponding electronic device. The electronic devices 22, 23, 25 are turned off. Specifically, after clicking the start button, the third server 15 transmits a third operation signal to the corresponding electronic devices 22, 23, 25 via the second server 13, so that the corresponding electronic devices 22, 23, 25 respond Turn on after the third operation signal. After clicking the close button, the third server 15 transmits the fourth operation signal to the corresponding electronic devices 22, 23, 25 via the second server 13, so that the corresponding electronic devices 22, 23, 25 respond to the fourth operation signal then close.

The real-time image interface displays the real-time images captured by the electronic devices 22 , 23 , 25 . For example, an example will be described in which the electronic devices 22 , 23 , and 25 include surveillance cameras, and the surveillance cameras capture scenes of the crime scene to generate real-time images. After the terminal device logs into the second server 13 and connects to the third server 15, it can directly or indirectly connect to the surveillance camera to obtain and display real-time images on the real-time image interface for customers to monitor the case at any time instant status.

The abnormal image interface displays the surveillance video images captured by the electronic equipment 22 , 23 , 25 in the abnormal state. For example, electronic devices 22, 23, 25 include surveillance cameras and the example of the door and window sensor for illustration, when the door and window sensor detects abnormal behavior (such as the door and window are opened abnormally), that is, when the abnormal state (equipment signal indicates an abnormal state), the security host 21 generates a trigger signal to the monitoring Camera, so that after the surveillance camera responds to the trigger signal, it transmits the surveillance video images generated by shooting the crime scene to the second server 13 within a period of time (such as before and after 15 seconds) before and after the time point of the abnormal behavior. The third server 15 obtains the surveillance video images from the second server 13, and displays the surveillance video images through the abnormal image interface, so that customers can directly view relevant images of abnormal behavior without viewing other irrelevant images. In some embodiments, the surveillance video image can also be transmitted to other servers outside the security image control system 10 (such as Amazon cloud service), and the surveillance video image is transmitted to the third server 15 .

In some embodiments, the abnormal image interface also emits a warning sound to remind the customer that there is an abnormal behavior in the case. In some embodiments, the abnormal image interface also marks electronic devices 22 , 23 , 25 that are in abnormal state. For example, the types, names and positions in the map data of the electronic devices 22 , 23 , 25 in abnormal states are marked with visual patterns. In this way, the customer can quickly know which electronic device 22 , 23 , 25 sends an alarm due to detection of abnormal behavior.

In some embodiments, the application on the customer's first terminal device sends an invitation to connect to the visitor's second terminal device. For example, the client operates the application program of the first terminal device to log in to the second server 13 and generates an invitation link, and transmits the invitation link to the second terminal device via the network. The second terminal device downloads the application program according to the invitation link, and the visitor inputs the visitor information into the second terminal device, and the second terminal device uploads the visitor information to the second server 13 through the application program and the network. In some embodiments, visitor information may be stored in a user database. In some embodiments, the visitor information includes visitor identity information, visitor's avatar image, visit time, and the like.

In some embodiments, the check-in QR code is, for example, a QR code.

In some embodiments, the second server 13 scans the check-in QR code through the application of the second terminal device to obtain the check-in message. For example, the application program of the visitor's second terminal device scans the check-in QR code through the image capture device (such as a camera) of the second terminal device to generate a check-in message, and transmits the check-in message to the second server 13 through the network. The second server 13 judges whether to open the visitor gates in the electronic devices 22 , 23 , 25 of the security system 20 according to the visitor information and the check-in information. Specifically, the second server 13 compares whether the visitor identity information of the visitor data matches the check-in information, and if the visitor identity information matches the check-in information, then opens the visitor gate for the visitor to enter the case site and then go to the destination (such as a conference room). If the visitor's identity information does not match the registration information, the visitor gate will be closed to refuse the visitor to enter the case.

In some embodiments, the hardware device (such as a computer) that enters the front end of the third server 15 through user account login may be equipped with an image capture device (such as a camera), which can capture the visitor's face To generate a face image to be identified, and the hardware device can transmit the face image to be identified to the third server 15 through the front end and the network, and the third server 15 is based on the avatar image in the visitor data and the image to be identified Face recognition is performed on the face image to generate a recognition result, and it is determined whether to open the visitor gates in the electronic devices 22 , 23 , 25 of the security system 20 according to the recognition result. Specifically, when the recognition result is that the avatar image matches the face image to be recognized, the visitor gate is opened for the visitor to enter the case and go to the target location (such as a conference room). If the recognition result is that the avatar image does not match the face image to be recognized, the visitor gate is closed to deny visitors from entering the case.

In some embodiments, after the visitor gate is opened, the second server 13 via The network sends the guidance data to the second terminal device to be displayed on its application program. The guidance material may be a map showing how to get to the destination. In this way, the visitor can go to the destination according to the guide information.

In some embodiments, the monitoring interface includes a visitor tracking interface and a visitor time limit interface. The visitor tracking interface displays the visitor's current location and communicates with the visitor through the application program of the second terminal device. For example, the electronic equipment 22 , 23 , 25 includes a surveillance camera as an example for illustration. The surveillance camera can continuously follow the visitor and take pictures of the visitor so as to transmit a tracking image to the second server 13 . The third server 15 can perform image recognition to determine the current location of the visitor based on the tracking image and the relevant map information (such as topographic plan or topographic three-dimensional map) in the device information display configuration file, and display the current location of the visitor in the visitor tracking interface. In this way, the customer can track the travel line of the visitor in the case to ensure that the visitor does not get lost. In some embodiments, the tracking image can be stored in other servers outside the security image control system 10 (such as Amazon cloud service), and the tracking image is transmitted to the third server 15 . In some embodiments, the visitor tracking interface has a visitor call button.
