PROBLEM TO BE SOLVED: To provide a monitor camera transmitter for transmitting a video captured by a camera by radio by using a power source having a solar cell and a secondary cell in combination. SOLUTION: Any or both of the solar cell, the secondary cell, the camera, a radio equipment and a calling button or a sensitive sensor are integrally constituted in a planar state so as to have a structure to be simply mounted in an outdoor exit/entrance. Thus, the video captured by the camera is automatically transmitted by radio by pressing the button by a visitor or by operating the sensor.
