"It" being the camera? If we're talking about an SLR, you are in control, not "it". Stick that puppy in aperture priority, open it up to 1.8 and crank the ISO. My entry SLR from 6 years ago takes great shots even at ISO 800. New ones can probably quadruple that.
By putting it in aperture priority mode, you can let the camera choose the optimum shutter speed while guaranteeing that the aperture stays at what you set (presumably the highest - f/1.8)
In order to make sure the shutter speed the camera selects for you isn't too slow and causes blurriness, boost up your ISO to as high a value as acceptable (acceptable is subjective here).
