Consumer accelerometers aren't that good, you are taking $2500 or so for one that car racers use. I analyzed it to death and came to the conclusion that 1 will be good enough for a project which is the reverse of the camera being described: that is, put a neopixel strip on the side of my car and generate i think high quality images at night if someone happens to be focused at about the right distance but NOT tracking the vehicle.
