So far my biggest problem has been finding one small enough. I have found them with the proper watts/amps to power the camera but they've all been 8" or more in length. I want to wire it in off the reach solenoid wiring so that the operator can press both the reach/retract buttons, which goes into bypass but still powers the camera so that the operator can get a look at the condition of the pallet before he actually picks it and can then watch his forks enter the pallet. Closed circuit TV for $250.

If you search DC DC Converter 36v to 12V you should have no problem finding one. Make sure the wattage is suitable for your application.
