Network audio and video device and related monitoring system and control method

The present invention relates to an audio-visual apparatus and related monitoring system, and more particularly to a network audio-visual apparatus and related monitoring system and control method thereof.

It is well known that traditional analog cameras, which generate analog audio signals, need to be transmitted to the host via a coaxial cable. The surveillance system built by the analog camera requires a coaxial cable to be connected between all analog cameras and the control host, which requires high line cost.

A network video/audio device, such as an Internet Protocol Camera (IP Camera), can generate a digital video stream and transmit the video stream over the network. In other words, as long as a network audio and video device is connected to one end of the network, the control host can receive the video stream at the other end of the network and perform remote monitoring, thereby greatly reducing the cost of the line laying.

Take the monitoring system consisting of multiple IP cameras as an example. All network cameras are placed in different locations on a single device. When the user uses the computer as the control host and connects to the network to view all the web cameras, the user needs to use a web browser to connect to the IP camera's individual IP address ( IP address), and enter the user account and password before you can pick up Receive the video stream of the webcam and watch the instant screen of each webcam, or set the function of the webcam.

In other words, if there are 4 network cameras on the monitoring system, the user must enter the IP address, user account and password four times on the control panel before they can watch the instant pictures of the four network cameras. Or function settings.

However, if the user wants to use another computer as the control host and connect to the network to view all the network cameras, the user must repeat the input IP address, user account and password before viewing the network. The instant screen or function setting of the road camera.

In other words, if there are multiple control hosts connected to the network to view all the network cameras, the above-mentioned input IP address, user account and password must be executed on each control host. When there are more network cameras on the monitoring system (for example, 16 network cameras), it is conceivable that such actions will cause great inconvenience and trouble to the user.

The object of the present invention is to provide a network video and audio device and related monitoring system and control method. In the monitoring system, there is a main network audio and video device that can search for other secondary network audio and video devices on the network according to the user's control, and obtain the IP address and user account of the secondary network audio and video device. And a password, and a database is built accordingly. Furthermore, in the main network audio and video device, a permission correspondence table can be established. When the user logs in to the main network audio and video device by using the IP address of the main network audio and video device, the main network audio and video device is based on the user account. According to the authority correspondence table, The network audio and video device permission login data is provided, and the user can simultaneously view the instant pictures of multiple network audio and video devices or change the setting parameters.

The invention provides a monitoring system, comprising: a network; a plurality of secondary network audio and video devices connected to the network; a main network audio and video device connected to the network, the main network audio and video device includes a a database and a permission correspondence table, wherein the database records an IP address in each network audio and video device, a user account for random setting, a random setting password, a random viewing user account, and a a random viewing password, the permission correspondence table records the usage rights of the secondary network audio and video devices corresponding to the plurality of user accounts; and a control host connected to the network, using the first of the user accounts A user account is logged into the primary network audio and video device, and receives a network audio and video device permission login data returned by the primary network audio and video device, so that the control host logs in according to the network audio and video device permission login data. Want a network audio and video device.

Furthermore, the present invention provides a control system control method, the monitoring system having a main network audio and video device, a plurality of secondary network audio and video devices and a control host connected to a network, and using the control host to operate, The method includes the following steps: connecting to the primary network audio and video device according to an IP address of the primary network audio and video device; inputting a user account and a password to log in to the primary network audio and video device; receiving the primary network video and audio The device returns a network audio and video device permission login data; and logs in to the secondary network audio and video devices according to the network audio and video device permission login data.

In order to better understand the above and other aspects of the present invention, the preferred embodiments are described below, and in conjunction with the drawings, the detailed description is as follows:

Since the network audio and video device in the conventional monitoring system needs to input an IP address, a user account and a password respectively to log in and set, it often causes trouble for the user. Therefore, the network video device of the present invention and its related monitoring system and control method can allow the user to view the instant pictures of all the network audio and video devices only after logging in to a main network audio and video device in the monitoring system. In the following examples, web cameras are used as network audio and video devices for explanation and explanation.

Please refer to FIG. 1 , which is a schematic diagram of a monitoring system composed of a network audio and video device. The control host 30 is connected to the network 20 by four network cameras 10, 12, 14, 16. The control host 30 can be a personal computer or a network video recorder (NVR), and all the IP cameras have different IP addresses, and the first network camera 10 is a main network camera. (primary IP camera), other The web cameras 12, 14, and 16 are secondary IP cameras.

Please refer to FIG. 2A, which is a flow chart of the automatic searching of the main network camera in the monitoring system by the user. First, the user connects to the main webcam 10 by using the control host 30 and according to the IP address of the main webcam 10, and then logs in to the main webcam 10 using the user account and password (step S202). Next, the main network camera 10 is controlled to perform a device search operation, so that the main network camera 10 issues a broadcast get information command on the network 20 (step S204). Next, the primary network camera 10 can receive the IP addresses and device information transmitted by all of the secondary network cameras 12, 14, 16 via the network 20 (step S206). Basically, the device information includes the model of the network cameras 12, 14, 16 and the supported protocols.

When the primary network camera 10 has obtained the IP addresses of all of the secondary network cameras 12, 14, 16, the primary network camera 10 uses the IP addresses of the secondary network cameras 12, 14, and 16 sequentially. Wire and log in to the secondary network cameras 12, 14, and 16. After the secondary web cameras 12, 14, 16 are logged in, the secondary web cameras 12, 14, 16 are controlled to generate a random user account and password (step S208).

Finally, after the primary webcam 10 has obtained the random user IDs and passwords for all of the secondary web cameras 12, 14, 16 the primary webcam 10 can then create a database (data base). (Step S210), and this automatic search flow is ended. Of course, the main network camera 10 can also generate the random user account and password of the main network camera 10, and all the network cameras 10 are included in the database. 12, 14, 16 random user account and password.

Please refer to FIG. 2B, which is illustrated as a detailed operational flow of the step S208. Taking the monitoring system of Fig. 1 as an example, there are three secondary network cameras 12, 14, and 16, so M=3. Basically, the primary network camera 10 logs in to the secondary network camera 12 with a default user ID (default ID) and a default password (for example, a default account: admin and a default password: admin). 14,16.

First, N=1 is set (step S212). Next, the primary network camera is connected to the first (N = 1) secondary network camera 12 based on the first (N = 1) network IP addresses (step S214). Next, the primary webcam 10 logs into the first (N=1) secondary webcam 12 using the default user account and the default password.

When the preset user account and the preset password are entered into the first (N=1) secondary network camera 12 cannot successfully log in (step S218), the primary network camera 10 notifies the user to type the first (N=1). The user name and password of the secondary webcam 12 are entered and entered into the first (N = 1) secondary webcam 12.

Upon successful login to the first (N=1) secondary webcam 12 (step S218), the primary webcam 10 controls the first (N=1) secondary webcam 12 to generate a random user account and password ( Step S222).

Thereafter, it is judged whether or not N is equal to M (step S224). When it is determined that N is not equal to M, all the secondary network cameras 12, 14, 16 are not yet logged in, so N is incremented by 1 (N=N+1) (step S226) and step S214 is continued; otherwise, When it is determined that N is equal to M, it means that all the secondary network cameras 12, 14, and 16 have been successfully logged in and generated random. User account and password, so this process ends.

Therefore, when N = M = 3, the random user accounts and passwords of all the secondary network cameras 12, 14, 16 are passed to the primary network camera 10, and a database is created accordingly.

Please refer to FIG. 2C, which is a schematic diagram of a database in the main network camera of the present invention. The database includes the IP address of each of the webcams 10, 12, 14, 16 and the random user account and password. Among them, the random user account and password include a random setting user account (random setting ID), a random setting password (random setting password), a random viewing user account (random preview password), a random viewing password (random preview) Password). Basically, the permissions for setting up a user account are higher than the user account for viewing. In other words, when you log in to the webcam by setting the user account, you can modify the setting parameters of the webcam in addition to the instant screen of the webcam. Furthermore, when viewing the webcam by viewing the user account, only the instant screen of the webcam can be seen, and the setting parameters of the webcam cannot be modified.

Please refer to FIG. 3, which is a flow chart showing the actions of all secondary network cameras when the user performs an automatic search in the monitoring system. The following is only the operation flow of the first time network camera 12, and the operation processes of the other secondary network cameras 14, 16 are the same, and will not be described again.

Basically, the first time the network camera 12 continues to wait for an external command (step S310). When the command of the main network camera 10 is received, it is first determined whether or not the broadcast command is obtained by the information (step S312). If so, the first webcam 12 returns its IP address and device information to the primary network. The road camera 10 (step S314) returns to step S310; if not, it is determined whether a random user account and password command is generated after logging in to the first secondary network camera 12 (step S316). If so, the network camera 12 stores the self-generated random user account and password for the first time, and returns the random user account and password to the primary network camera 10 (step S318) and returns to step S310. If not, the instruction is another instruction not related to the present invention, and after executing the other instruction (step S320), the process returns to step S310.

After the above actions are completed, the network administrator can establish a rights correspondence table according to different users, and the users of different needs can utilize the monitoring system. Please refer to FIG. 4, which is a schematic diagram of the authority correspondence table. This privilege correspondence table is built into the main webcam 10 by the network administrator.

For example, the network administrator can establish a permission correspondence table in the main network camera 10, and the data in the database can be used by different rights users to use the network camera 10 according to different user accounts and passwords. , 12, 14, 16

For example, as shown in the first column of Figure 4, the network administrator can establish the highest-privileged user account (Admin_1) and its password (Admin_highest) for the highest-privileged users to control the network cameras 10, 12, 14,16. In other words, when the user ID (Admin_1) with the highest authority and its password (Admin_highest) are used to log in to the main webcam 10, the permission correspondence table indicates that the setting parameters of all the web cameras 10, 12, 14, and 16 can be Modified and can view real-time images of all webcams 10, 12, 14, 16.

As shown in the second column of Figure 4, the network administrator can establish the first The user account (User_1) of the first user group and its password (Test_987) are used by the users of the first user group to control the network cameras 10, 12, 14, 16. In other words, when the user account (User_1) of the first user group and its password (Test_987) are used to log in to the primary network camera 10, the setting parameters of the secondary network cameras 12, 14, 16 can be known from the rights correspondence table. It can be modified, and the setting parameters of the main network camera 10 cannot be modified. In addition, you can view real-time images of all network cameras 10, 12, 14, and 16.

In other words, the network administrator can create user accounts and passwords for the second user group, the third user group, the fourth user group, and the fifth user group in the rights correspondence table, and define individual network cameras. The usage rights are used to control the network cameras 10, 12, 14, 16.

Please refer to FIG. 5A, which is a flow chart of the user using the control host to log in to the main network camera and using the monitoring system. First, the user connects to the main webcam 10 by using the control host 30 and the IP address of the main webcam 10 (step S510). Next, the user logs in to the primary network camera 10 using any of the group of user accounts and passwords in the rights correspondence table (step S512).

After successfully logging in to the main webcam 10, the main webcam 10 queries the permission correspondence table according to the logged-in user account and password, and then uses the database to obtain the webcam permission login data, and returns the webcam permission login. The data is sent to the control host 30 (step S514).

Thereafter, the control host 30 individually logs in to the relevant webcam based on the webcam permission login data to view the instant screen or control the associated webcam (step S516).

Please refer to FIG. 5B, which is a flow chart showing the login information of the webcam permission generated by the main webcam according to the user account. First, the main web camera 10 queries the authority correspondence table based on the user account and obtains the usage rights of all the web cameras (step S520). Then, according to the usage rights of the individual network cameras, the user account and the random setting password or the random viewing user account and the random viewing password of the individual network cameras are obtained from the database, and then the network is generated. The camera authority login information (step S522).

Taking the rights correspondence table of FIG. 4 as an example, when the user with the highest authority uses the IP address of the main network camera 10 on the control host 30 to connect to the main network camera 10 and the user account with the highest authority (Admin_1) After logging in to the main webcam 10 and its password (Admin_highest), the main webcam 10 automatically returns the webcam permission login data including: the IP address of the main webcam 10, the user account for random setting, and random Setting password; first time IP address of network camera 12, user account for random setting, password for random setting; IP address of network camera 14 for the second time, user account for random setting, random The password for setting; the IP address of the network camera 16 for the third time, the user account for random setting, and the password for random setting.

Thereafter, the control host 30 uses the backhaul IP address, account number, and password to sequentially connect and log in all the network cameras 10, 12, 14, 16 and can view the instant screen or change the setting parameters.

When the user of the first user group connects to the main webcam 10 on the control host 30 using the IP address of the main webcam 10 and logs in to the main network with the user account (User_1) and its password (Test_987). photography After the machine 10, the main network camera 10 automatically returns the network camera permission login information: the IP address of the main network camera 10, the random viewing user account, the random viewing password; the first time the network camera 12 IP address, random user account, random password; second IP camera 14 IP address, random user account, random password; third network camera 16 IP address, user account for random setting, password for random setting.

Thereafter, the control host 30 uses the backhaul IP address, account number, and password to connect and log in to all of the network cameras 10, 12, 14, 16. Obviously, the user of the first user group can only view the instant screen of the main webcam 10 and has no right to modify the setting parameters of the main webcam 10; the user of the first user group can view all the secondary Instant screens of the network cameras 12, 14, 16 or changing setting parameters.

Similarly, the main network camera 10 can also obtain the webcam permission login data according to the user accounts of the second user group, the third user group, the fourth user group, and the fifth user group.

As can be seen from the above description, the present invention utilizes the automatic search function of the primary network camera 10 to create a database. And the user establishes a permission correspondence table in the main network camera according to different permissions. Therefore, the user does not need to record all the relevant user accounts and passwords of the webcam. The user only needs to input the messenger account number and password of the main webcam 10 to successfully use all the web cameras in the monitoring system.

Similarly, no matter how many control hosts are in the monitoring system, each control host can connect to the network 30 and only need to input the IP address of the main network camera and the user account and password to successfully use the monitoring system. All web cameras.

In conclusion, the present invention has been disclosed in the above preferred embodiments, and is not intended to limit the present invention.
