Great work using a 8051 ! video on 8051 is something that i rarely can imagine !, so don't forget the 8051 inside stickers ;)

Do these cameras ouput a digital signal (or some analog outputs for R,G,B chanells)? or do they need to use something like a video DAC ? i searched yesterday on the CCIR and found out it is a Standard definition and found nothing on how the output signal is.
Did you used some sort of video DAC in your project or do you used discrete components.

I realy was in the hope of having ability to add some vision to my robots (even a 64x64 pixel 2-3 Fps would be nice , of course just for view/send ,not to process the image data by 8051), if you know of a good link or how to do such a thing , i will be really appreciated from your help.

Sorry if i'm mistaking in something ,cause i'm really new to this field.
