The transmitter 1 shown in FIG. 1 is provided with a viewing hole 2a through which the lens of the camera 2 looks. A solar cell 3 is arranged on the outer surface of the transmitter 1, and the solar cell 3 generates electric power by sunlight. This electric current is transmitted through an electric double layer capacitor 9 and a power supply control circuit 10 shown in FIG. The secondary batteries 8 and 8a such as a lithium ion battery and a proton polymer battery are charged. Therefore, a large part of the main body is occupied by the power supply. When one voltage, current and power capacity of the secondary batteries 8 and 8a are sufficient, it is not necessary to use two as shown in the figure, but if this is not enough, the number must be further increased.

Generally, the voltage required for a CCD camera is 6 V to
Since the voltage is 12 V and the current is about 100 mA to 150 mA, power generation and charging can be sufficiently performed by sunlight. When a CMOS camera is used instead of a CCD camera, the CMOS camera can be operated with a lower current value. Therefore, if the CMOS camera is inexpensive and has high performance, the CMOS camera is better.

A video image received by a CCD camera or a CMOS camera is transmitted by a UHF transmission unit 7 (13 ch to 27 ch, BS tuner 1.2 to 1.3) by NTSC or PAL.
(E.g., GHz or the like) and transmit via the antenna 5. Since reception can be easily performed in a frequency band that is within a reception range of a conventional TV receiver (hereinafter, referred to as TV), it is possible to use a frequency that does not disturb this range and operate with a very small power that does not disturb other components. desirable.

Other frequencies such as BlueTooth, which is known as a power-saving wireless communication standard, and 2.4 GHz of a wireless LAN may be used. For business use, a dedicated frequency may be used, or a digital video signal may be transmitted.

In many cases, the transmitter 1 is installed in a bright place at the entrance or outdoors in the sunshine, and the solar cell 3, the secondary battery 8, the electric double layer capacitor 9 and the proton polymer battery are used.
