This project have two part


   I use a microcontroler from   ELM Electronics whith undertakes to adapt the tensions
   and convert the frames

   its price is competitive less than CAN 11$ 
   the payment  is securited, the delivery fast. 
   It is thus enough to question the microcontroler with command, as for a modem
   and  interpret the received frames.

   the pcb is very simpe , and the assembly can be placed in a small case.

photogragh of terminated pcb


if the power of the video camera power supply is strong
                          the feeding can be take on the power supply lanc pinout

 

 the soft part is composed of a small  program  in Visual Basic
 which interpret the frames and control the video camera.
 after understand the frames, you can develop all other control program,
 under another language.
