Methods, systems, and techniques for adjusting camera focus to facilitate infrared imaging are employed to account for a difference in wavelength between visible and infrared light to permit sharp imaging regardless of whether imaging is performed using visible or infrared light. Camera focus is adjusted in accordance with base and offset values. The base value may be determined in accordance with a curve relating focus motor position and object distance and the offset value may be manually set by the user or automatically set by performing an autofocus method when the camera is operating in low light conditions.
