A video recording apparatus of videophone contained function of wireless transmission and detection sence of body}

The present invention records the detection sensor and the detected image information to the office or home video phone or the object detection sensor that can protect the social crime and personal property by transmitting the corresponding image information to the wireless terminal of the user set And a video phone image recording apparatus equipped with a wireless transmission function and an image recording method using the same, comprising: a sensor unit capable of detecting sound and an object on one side of the video phone, the sensor unit being connected to a driving range and a sensing area of the sensor unit; A sensor setting unit capable of setting an image, an image recording unit for recording corresponding information when a movement of the object is detected by the operation of the sensor unit according to the setting of the sensor setting unit, and for storing the information recorded in the image recording unit Recorded image storage unit classified into time, repetition frequency, playback condition, input state, etc., and the image recording unit It is composed of a video information transmission unit for wirelessly transmitting to the terminal device, such as a user, a public office, a police station, a fire station, etc., which is input during an emergency situation by judging image information, and a display unit for driving and displaying the image information stored in the image storage unit. The present invention provides a video phone image recording apparatus equipped with an object detecting sensor and a wireless transmission function and a video phone operating method using the same. In addition, the camera is installed in the indoor video phone, and the device is equipped with an operating system that can transmit the indoor situation to the guard room or the outside when the user operates the wireless remote control in a fire, intrusion or emergency situation.

In general, the video phone apparatus may be roughly classified into an outdoor unit installed in a door for each furniture and an indoor unit installed in an indoor. The outdoor unit is equipped with a camera, a handset, and a doorbell switch, and the indoor unit is equipped with a handset, a display, a door lock release switch, and various switches for setting a method function, so that the homeowner can open the door by checking the visitor's image on the display. To make it possible.

The video phone device is configured to be connected to a large frame memory such as a large capacity memory (RAM), a magnetic tape, and a DVD device in an indoor unit, so that the video information of the visitor can be recorded in the absence of a resident.

As shown in FIG. 1, the door video phone includes a camera unit 110 installed at an entrance side and a monitor unit 120 installed indoors.

The camera unit 110 includes a camera 111 for photographing a visitor, a microphone 112 for recognizing a visitor's voice, a speaker 113 for transmitting a voice generated indoors to the outside, and a button for generating a melody. 114 and a melody generating device 115 are provided.

The monitor unit 120 transmits an external visitor's voice and transmits the user's voice to the outside, a monitor 122 displaying an image captured by the camera 111, and a camera unit 110. Control panel 124 and each component having a melody generating device 123 for generating a melody in conjunction with the melody generating device 115, a plurality of keys for the operation and other control of the monitor 122 The control apparatus 125 is provided.

Looking at the operation of the conventional door video phone, when the visitor manipulates the button 114 from the outside, the melody is generated in the melody generator 115 of the camera unit 110 and the melody generator 123 of the monitor 120. Will occur. At this time, the monitor 122 of the monitor 120 always photographs the visitor under control, or photographs the visitor according to a separate operation.

In this state, when the user indoors calls the visitor by lifting the handset 121, the user's voice is transmitted to the visitor, and the visitor's voice is transmitted to the user.

Thus, the user confirms the visitor through the monitor 122 and at the same time confirms the situation, opens the front door or rejects the visitor.

In the video information storage method of the conventional video phone device, the video and audio information is automatically recorded in the memory only when the visitor is approached during the absence of the tenant, or when the visitor shows a suspicious behavior that does not press the doorbell for a long time. It is to reduce the waste of memory.

However, even in a videophone device having such an auto-save function, if the lamp in front of the front door is disconnected and not lit, the image of the visitor shot and stored through the camera at night is virtually impossible to identify. Memory waste due to the large amount of storage of image information comes to the fore.

In addition, the conventional video phone device generates an alarm signal when the visitor forcibly blocks the camera, but continuously exhausts the memory by storing image information without identification. In addition, the conventional video phone device automatically records when a passing pedestrian stays in front of the camera and records it in the memory. When the memory is wasted for various reasons described above, an area for storing other visitors thereafter is stored in the memory. There is a problem that does not remain.

In addition, when the visitor forcibly damages the camera or forcibly invades the house, the visitor fails to respond promptly, resulting in additional property loss.

The present invention has been made to solve the above problems, the object is that the user can set the condition, distance, external environment state, etc. for the object to be detected such as external objects and sounds through the sensor setting unit It is possible to change the information for the variably, and to change the recording time, repetition frequency, input state, etc. of the video information according to the situation, and to store and drive the recorded video information.
