6 is an operation flowchart of a video security device control system using a smartphone according to an embodiment of the present invention.

First, the user registration process will be described.

When the user places the smartphone on the NFC pad while the control app is running, the communication channel between the smartphone and the NFC pad is activated through NFC. The driving and operation of the control app may be performed through a keypad provided through the UI in the control app.

The NFC pad receives device unique identification information from the smartphone on which the control app is driven (S100). The device unique identification information may use a smartphone model name, a serial number, a MAC address, an International Mobile Subscriber Identity (IMSI), and the like, and may be automatically collected by a control app. Preferably, the device unique identification information may be transmitted through a known encryption algorithm to further increase security.

Device specific identification information is transmitted to the computing means further connected via the NFC pad and the serial communication interface (S200). The computing means may be a normal PC on which a control management utility program is installed, and stores the unique user identification information of the authorized user and the smartphone, data on the range of usage rights granted by each user, and the like. The computing means which has received the device unique identification information checks whether the user is registered with the corresponding smartphone and the range of the use authority based on the data stored or input by the administrator.

The NFC pad receives the confirmation information from the computing means for which the user registration of the corresponding smartphone and the range of the usage rights have been performed, and stores the user registration information in the memory (S300). The user registration information includes device-specific identification information of an authorized user and a smartphone, data regarding a range of usage rights granted to each user, and the like.

The range of usage rights may include identification information (eg, device ID, protocol, model, etc.) of a controllable device such as a DVR and a PTZ camera, and may include controllable operation contents and duration of the corresponding smartphone. It may be.

Through the above process, user registration information and usage authority range information about a user to whom control authority is granted are stored in the memory of the NFC pad. After this storage process is completed, it is desirable to separate the computing means from the NFC pad.

On the other hand, when the number of authorized users increases, there may be a limitation in the storage space of the memory. For this purpose, the computing means may be connected at all times, and the user registration information and the usage right range information may be constantly managed by the computing means. However, in this case, it is preferable to operate a separate security management program for the computing means.

As another example, some of the user registration information and the usage right range information may be stored in the corresponding smartphone through the control app and configured to be used in conjunction with information stored in the memory of the NFC pad. For example, the user registration information may be stored in the memory of the NFC pad, and the usage authority range information may be configured to be stored in the smartphone. In addition, it is desirable to increase the security by applying a known encryption algorithm in this process.

Next, the control process will be described.

When the user registered with the control has placed the smartphone on the NFC pad while driving the control app, the communication channel between the smartphone and the NFC pad is activated through NFC (S400).

NFC pad receives the device unique identification information from the smartphone and compares it with the user registration information stored in the memory (S500).

If the user is confirmed as a registered smartphone, the corresponding smartphone maintains a state in which control data can be input within a range of pre-stored usage rights (S600). User manipulation via the control app may be accomplished via a keypad provided via the UI in the control app.

In another aspect, this state can be understood as being converted from a normal communication channel to a control channel. In the state converted to the control channel, the first control module of the NFC pad periodically reads the NFC module and determines whether a control command is input from the smartphone.

The control data is input from the smartphone through NFC and converted to a signal suitable for each device characteristic by a camera or an image storage means and transmitted (S700).

For example, a control operation for each device may include a zoom control, a focal control, or an OSD control.

In case of PTZ camera, PRESET, TOUR function, etc. can be set in addition to basic PAN, TILT, ZOOM operation.

In case of DVR, you can record, play through search, play at double speed, change setting.

After the device control is performed as described above, if the user terminates the control app or leaves the smartphone from the NFC pad for a predetermined time, the control process is terminated.

Unexplained code S1000 may be understood as a user registration process, and S2000 may be a user authority authentication process.
