a better first approximation of the LM386 is a voltage-controlled voltage source that just happens to be built to pass relatively large currents and is programmed for a 20x voltage gain by default. usually, power concerns are treated separately from signal concerns

fixed that for you
>isn't actually amplified as such
but that's exactly what amplification is: controlled passage of power between a source and an output, according to an input

if it uses stepper motors and you drive them properly, you would, or should, always know where the camera is pointing
