Description

Technical area

The The present invention is concerned with a visual doorbell.

Technological background

The existing visual doorbell contains an inner door-receiver unit and an outside door transmitting unit, of which the outer door transmitter unit a Contains a camera and a microphone, while the inner door receiving unit a visual display equipment contains. The common feature of the two equipments is that both have the wire connection connection mode. Furthermore it is required wiring in addition to create so that the visual display device after completion of the wiring layout is immovable. The conventional flat tube monitor is in size expansive, which is an inconvenience and also a Nichttragbarkeit means.

Detailed description the invention

It is a general object of the present invention to provide a solution to the problem described, that is, a visual doorbell should have only a wired connection, but not a portable display. The technical solution according to the present invention (which provides a wireless B / W multicolor visual door bell with intelligent transmission control and with portable LCD and external lines) consists of the following:
It consists of an inner door receiver unit and an outer door transmitter unit. The outside door transmitter unit includes a camera, a microphone and a switch, while the inside door receiver unit is a visual display equipment. Their characteristics are as follows:
The camera and the microphone of the outer door transmitter unit have an electrical connection to the wireless audio / video transmission transmitter and the transmitter of a wireless remote controller via said switch, respectively, and the switch of this unit consists of an automatic switch, which with a microwave infrared detector is connected. In the automatic switch, one end is connected to the camera, while the other end is connected to a power supply plug.

The Interior Door receiver unit includes an LCD monitor connected to the wireless audio / video transceiver is. The power supply input end of the LCD monitor has electric power Connection to the transformable plug of the power supply, after connecting to the wireless remote controller is.

Of the Automatic switch of the outside door sender unit is connected to a lighting lamp.

Of the called wireless remote controller consists of a coded 315th MHz radio remote controller. Said wireless audio / video transmission transmitter consists of a coded wireless audio / video transmission transmitter.

One Input interface of the LCD monitor is with an interface of the wireless Audio / Video transceiver connected.

usability

At the The subject of the invention is no need for a connection of loads between the inner door-receiver unit and the outside door transmitting unit build. The portable, ultrathin and true color LCD monitor is for Designed a low power consumption, which is the carrying capacity problem Ultimately solves. The frequency of the encoded wireless transmission or transmission, the through the wireless remote controller used is 315 MHz, which is a private frequency for a warning device is in our country and the encoded wireless transmission is stable and will not disturbed by cofrences and adjacent frequencies. In our Country leads This certainly leads to mutual interference when open wireless audio / video transmission concentrated in other areas on only one frequency point. The 1G-4 frequency is for the wireless audio / video transmission of the present invention, the advantages thereof in the following to be listed:

These Frequency points are for that designed to be released by the government for use become.

The transfer characteristics these frequency points match the visual system environment.

Of the Price is also pretty low.

The Techniques for making the devices are not complex.

The mode, the group coding of individual frequency points is implemented to solve the technical problems of images in terms of mutual interference and in terms of transmission by only one single plant.

By the way the available transmission frequency is noticed around 14 MHz for the transceiver extended or widened by assigned frequency points below 600mA, which causes that the transmitter / receiver images the Reach grade four with a strong increase in grade of the message content. (intelligentization degree)

Operating principle of the invention

One Microwave infrared double resonance detector of the outer door transmitter unit can make a distinction as to whether a human body is in the defense area or surveillance area has penetrated within an effective range. When a person in the supervised or area of a gateway to be defended, identified the Microwave Infrared Double Resonance Detector the person and although after receiving the heat source and the movement rate, then immediately switches the relay of the Output automatic switch on for the camera and the microphone Supply electricity; meanwhile the camera starts the camera recording operation. Of the wireless microwave infrared detector receives encoded multimedia information after receiving output energy from the microwave infrared detector supplied and sends commands corresponding to the task code to the receiving end the inner door receiving unit and though over a wireless radio connection. Subsequently, the receiving end turned on as soon as this receives the command and provides drive power for the LCD monitor and the audio / video receiver. After the transformation of coded information, the LCD monitor displays the Pictures taken by the camera, what then to a Visual examination or effect leads and ultimately formed an intelligent automatic control system becomes.
