Not a stupid question at all. The sensor is located behind that domed shape piece you see on the front. Some of those fresnals, that's what they are called, are flat and some are domed shaped like you see on his cams. The domed shaped ones allow the camera to pick up motion a little faster so that it may trigger faster.
