Transmitting Camera Video wirelessly

[electroRF]

Hi,

I'd like to build wireless intercom.

The block diagram is as follows: (the blue lines are the connections between each 2 adjacent blocks)

{Camrea (Vid+Aud)} <-RS232-> {Miwi RF Radio} <--Wireless--> {Miwi RF Radio} <-I2C-> {LCD}

(Miwi RF Radio uses PIC18F46J50, 32KHz crystal)

Is it practical to transfer the Camera's video + audio Serially via RS232, then the data wirelessly via Miwi Radio, and then via I2C to a GLCD + Speaker?

Thank you.

What bandwidth does the Miwi RF Radio deliver?

I can't see the possibility of sending audio and video down RS232. :/

There are some JPEG cameras that talk RS232.

Fair comment.
I doubt it would be able to handle video and audio in real time, which is what I gather that the O.P. is requiring.

Audio and RS232 is not good.
The video can be compressed and sent very slow.

JPEG is for still pictures, MPEG is used for video. I believe the RS232 connection is for capture of single frames from the camera.

Yes it is.

I agree with the last two comments.
To transmit video you need the bandwidth of a broadcast transmitter. If you compress the video then less bandwidth. Many cameras are high resolution than broadcast so you need a faster signal. Either way you need a great deal of information in a short time. RS232 was never built for video or even just audio.

There are a number of 2.4ghz wireless cameras. They work but they seem to eat up the 2.5ghz band.
