The present invention is a CCTV phone (Tip-phone: 100) when the camera visits the visitor of the absent visited by a certain time unit of the still image and stores in the image memory, and equipped with sensors (70, 79) when outsiders invade Images of the sensor system 70 and 79 that are operated by the cameras 60 and 69 by a predetermined time unit, and the captured images are wirelessly transmitted to the TV system 100 which is the main system system. It is a simple security system that stores in the memory device 13 and automatically calls a phone number or email stored in advance using a trunk line (or a wireless mobile communication network). In addition, the security system using the image memory device 13 that solves the image data processing speed, storage capacity and the like is implemented.

The image memory device 13 operates a separate image processing processor to increase the processing speed by compressing and decompressing data, and is a device capable of maximizing the storage capacity. The microcomputer 30 of the monitoring system is a method of increasing the processing speed by transferring such image data directly to the memory and the screen in the image memory device without passing through the microcomputer 30. The image data can realize a sufficient processing speed during screen retrieval even by the serial bit storage method. The image data is serially transferred from the cameras 60 and 69 to the image memory device 13 via the controller 40 and serially transferred from the image memory device 13 to the monitor 80, but by the image memory device 13. Sufficient processing speed can be achieved. In addition, the stored still image has a function that can be checked at any time on the TV phone 100, and also plays a role of driving the intruder by generating a warning light and an emergency sound according to the needs and conditions of the consumer.

The selection switch 50 is a key for setting the mode and the function of the TV 100. At this time, when the sensors 70 and 79 operate, a signal input to the controller 80 is transferred to the microcomputer 30, and the image signals of the cameras 70 and 79 are selected and stored in the image memory device 13. In this case, when the cameras 70 and 79 can adjust the shooting angle, the shooting angle may be adjusted to capture a corresponding area, and when the cameras 70 and 79 support the dividing function, the cameras 70 and 79 may sequentially photograph multiple areas on one screen. Can be stored.

The microcomputer 30 automatically calls the telephone number in the telephone number memory 11 using the DTMF / telephone circuit 20 and services the information stored in the voice memory 12. In other words, the phone number is called and the voice stored in the voice memory is played to inform the user that an emergency has occurred. At this time, the corresponding region information according to the sensors 70 and 79 is also transmitted to inform in which region an emergency situation has occurred. The phone number and the pre-stored voice may be input and stored through a telephone, or may be input through a microphone or a key (not shown) provided in the TV 100.

Normally, the phone is connected to the telephone line, but when a security situation occurs, the TV phone 100 and the telephone line are connected so that an emergency situation can be notified and control of the microcomputer 30 even when storing a phone number and voice necessary for the notification. By the TV 100 and the phone is connected to enable various inputs.

The image stored in the image memory device 13 is output to the monitor 80 through the controller 40 according to the command of the microcomputer 30. The calling part of the interphone, the cameras 60 and 69 or the sensors 70 and 79 are independent systems, each having a separate power supply and communication network, and the transmission is wireless. These independent components make up a video surveillance system.

The TV 100 operates in a wireless connection type independent of an interphone or a video phone externally, and all image data are sequentially stored in the video memory system 13 of the TV 100. If the memory capacity is insufficient during storage, the oldest data is deleted to secure the storage capacity, and the latest image is stored.

Fig. 2 is a product in which the monitor 80 and the telephone functions 21, 22, and 23 are integrated into one unit. The basic concept of operation is the same as detachable, and all the functions are integrated into one. As with the separate type, it is usually used as a CCTV concept, and when not in use, it is converted to a security system.

As described above, the present invention has an advantage of operating a security system at a low cost with a high function by using an image memory device that stores a digital color image in an existing CCTV system.
