Claims3
A wireless camera, comprising:
- pick up means;
- encoding means for encoding video signals picked up by the pick up means to generate transmission data of a predetermined encoding system;
- modulation means for orthogonal frequency-division-multiplex modulating the transmission data encoded by the encoding means;
- transmission means for frequency-converting modulated signals generated by the modulation means into signals of a radio frequency band, and radiating frequency-converted signals via an antenna;
- battery means;
- and
- first housing means for housing the encoding means and the transmission means wherein the first housing means comprises:
- first connecting means for removably connecting a first portion of the pick up means to a first portion of the first housing means;
- second connecting means for removably connecting a second portion of the pick up means to a second portion of the first housing means;
- third connecting means for removably connecting the first housing to the battery means;
- and
- fourth connecting means for removably connecting the first housing to a transmission antenna;
- wherein the pick up means, the encoding means, the modulation means, and the transmission means are housed in a second housing.
