This matrix system 100 will be described in detail with reference to FIG. 2. In addition, although the connection of the camera 20 and the matrix system 100 was shown by wire in FIG. 1, of course, it can connect wirelessly.

Reference numeral 22 denotes a personal computer, 23 denotes a dedicated terminal made up of a keyboard or the like, and the matrix system 100 is externally connected by using a communication means such as a modem attached to the personal computer 22 or the dedicated terminal 23. Can be controlled.

Denoted at 5 is a D / A converter and an image output unit for D / A conversion of the digital output signal from the 4EA camera image synthesis unit 4 and outputting an analog image onto the monitor 21. The video of the channel is displayed.

(6) is a remote control interface, when the external camera is equipped with a rotator or a zoom lens, etc., the system analyzes the control command transmitted from the MPU to directly control the rotational state or the zoom function of the camera 20 This is an interface for connecting to an external device, and (7) is an input of a security sensor from a fuselage detector, a fire detector, and the like, which is integrally provided with the camera 20 installed externally, and converts an incoming signal when data is generated into an MPU. Send to (8) to notify the P / C or other monitoring device of the abnormality.

The MPU 8 is an 8-bit CPU that manages all the functions of the system. The MPU 8 receives commands from the operator and sends them to the matrix switch control unit 2, the remote control interface unit 6, and the security sensor input unit 7. And when receiving a camera selection command, transmits a command to the matrix switch control unit 2 through the data interface unit 9 so that a desired camera can be selected and displayed on a monitor.

That is, the data interface 9 outputs a control signal to the matrix switch control unit 2 so as to select four camera signals designated by the MPU 8 from among the camera signals supplied from the camera signal input unit 1, and also to the outside. A signal for controlling the state of the installed camera 20 is output to the remote control interface unit 6.

It can also make it easy to see where the camera is.

In the above embodiment, the monitor is divided into four areas so that four images are displayed on one monitor, and the compressed image is reduced to 1/4 size, but the MPU 8 includes an automatic selection function. In addition, the operator can select only the desired screen.

That is, it is possible to display only one specific screen by providing a stop function on the screen divided into four areas, and to configure an automatic function to repeatedly display all images output from the installed camera at regular intervals. If a video signal is not supplied from a camera in an area where the pass function is not used or a problem does not occur, the corresponding screen display may be deleted at a predetermined cycle.

As described above, according to the four-channel embedded matrix system of the present invention, it is possible to selectively display all camera images connected to each of the four divided monitor areas one by one. The location of the camera can be known, and the name of the recorded time and location is also displayed when the recording screen is played, so that the operator can cope with the exact situation.

In addition, according to the four-channel embedded matrix system of the present invention, the four-channel monitoring function is built in to integrate the four-channel monitoring and video matrix into one, and all functions can be controlled by using a personal computer or a dedicated keyboard.
