The "about" 1 amp is important. I would recommend you test the current draw with a meter to see what it actually is. The regulator on the Bot Board is only a 500mA regulator. The processor will take about 60mA, the rest is available for external devices. If the camera has IR LED's then it could draw that much. If it's just a simple camera it should not draw anything close to 1 amp. If it really does draw that much I would look into a BEC, preferably a switcher, not a linear one.
