Highway surveillance cameras or other automatic camera system needs to focus towards moving targets.
It requires camera lens to move following the instruction of controller/driver, to change lens focal point.
The slight movement is achieved with a micro linear stepper motor.
Due to the small weight of the camera lens, it does not need very big thrust to carry.
A 8mm or 10mm stepper motor is capable for the work.
