Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a visitor detection system that lights up a visitor who visits a front door at night to make it easier to see a door scope.

[0002]

2. Description of the Related Art A conventional door scope is mounted approximately in the middle of the door and has no light-up means by itself.

[0003]

For this reason, although it is easy to see because it is bright in the daytime, it may be dark at night, or the lights may be backlit and the face of the visitor standing in front of the door may not be clearly seen. Also, when you look out from inside the door with the door scope, the eyepiece is small, so it is necessary to bring your eyes closer, but if you bring your eyes close in this way, the door scope will be momentarily dark from outside visitors. , It can be seen that there is a person inside and looking into it. The present invention is proposed in view of such a point, and its purpose is as follows. a. Propose a visitor detection system that lights up when a visitor stands in front of the door at night. b. Propose a visitor detection system whose inside is invisible from outside the door scope. c. Proposing a door scope that has a wide field of view and allows you to look through it without even bringing your eyes close. d. Propose a door scope that automatically focuses on visitors approaching the door. e. Propose a visitor detection system that can record a visitor's voice. f. Propose a visitor detection system that can capture visitors.

[0004]

The constitution of the visitor detection system and door scope according to the present invention is as follows. 1. Day and night detection sensor, visitor detection sensor, lighting lamp,
It consists of a power supply and a control circuit. The control circuit detects the darkness when the signal from the day and night detection sensor exceeds a certain level, and when the visitor detection sensor detects a visitor, it turns on the power and lights the illumination lamp. Visitor detection system used in combination with a door scope configured to. 2. 2. The visitor detection system according to 1 above, wherein an illumination lamp and a visitor detection sensor are attached near the door scope. 3. A door scope that uses a wide-angle lens as the objective lens and a large-diameter eyepiece lens. 4. A door scope that incorporates an automatic focusing mechanism. 5. A microphone and a recording device for recording the voice of the visitor collected by the microphone are attached, and a control circuit for controlling the power supply of the recording device to be turned on when the visitor detection sensor detects the visitor is provided. The visitor detection system according to 1 or 2 above. 6. The visitor detection system according to any one of claims 1, 2 and 5, further comprising: a control circuit for attaching a photographic device to a door and automatically taking a shutter to photograph the visitor when the visitor detection sensor detects the visitor. .

[0005]

When the visitor stands in front of the door at night, the control circuit receives the signal from the visitor detection sensor to turn on the power of the illumination lamp for a certain period of time, for example, 10 seconds, or the visitor detection sensor detects the visitor. It is controlled to be ON only while the lights are on, and visitors are lit up. As a result, the face of the visitor can be easily seen when looking through the door scope. In addition, door scopes that use wide-angle and large-diameter eyepieces have a wide field of view,
The door scope, which is easy to see even if you do not bring your eyes close and has an automatic focusing mechanism, focuses on this visitor when a person stands in front of the door, and the face is clearly visible. If the recording and photography device is installed, the visitor detection sensor will detect if the visitor is detected.
It becomes N, the voice is recorded, and the face picture is taken automatically.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1, 2 and 3 are explanatory views of a system and a door scope of the present invention, wherein 1 is a door, 2 is a door scope, 3 is a detection system body, 4 is a day / night detection sensor,
5 is a lighting lamp, 6 is a power supply, 7 is a visitor detection sensor, 8
Is a control circuit, which controls the power supply 6 of the illumination lamp 5 to be ON for 10 seconds when the day / night detection sensor 4 detects a certain darkness and the visitor detection sensor 7 detects a visitor. Light up.

In the door scope 2, a wide-angle lens (fisheye lens) is used as the objective lens 9, and an eyepiece lens 10 having a large aperture (lens diameter) is used. Reference numeral 11 denotes an automatic focusing mechanism, which can focus on a person standing in front of the door scope 2. As this automatic focusing mechanism, those used in known cameras, telescopes, binoculars, etc. can be used as they are.

A recording device 12 is in a recording state when the visitor detection sensor detects a visitor, which operates at night or day. It will automatically turn off if it no longer detects the visitor. Reference numeral 13 denotes a visitor photographing device, which automatically takes a photograph when the visitor detection sensor detects the visitor, which also operates day and night.

[0009]

The effects of the present invention are as follows. a. Since the visitors are illuminated, it is easy to identify the person when looking through the door scope. b. Since it is not possible to see the movement of the inside person through the door scope by lighting up, it is effective when using the absence from the perspective of crime prevention. c. A wide-angle lens is used for the objective of the door scope and a large aperture is used for the eyepiece, which widens the field of view and is convenient because you can look outside without bringing your eyes close. d. By attaching the auto focus mechanism to the door scope, the face of the visitor can be better understood and is more convenient than the conventional fixed focus system. e. Since the voice and face of the visitor can be recorded or photographed, it is effective for crime prevention, and it is convenient that a message can be left in the recording device when the user is away.
