The name of the cameras comes from their long cylindrical shape, which vaguely resembles a bullet. The distinctive appearance is very recognizable, providing a visible deterrent to intruders - the main benefit here is that intruders are more likely to choose another target location if security cameras are seen. However, because they are more easily recognizable, they are also more prone to vandalism than dome cameras. The cylindrical shape also allows you to focus on a still view, such as specific entry or exit points. Since you only have one fixed view, you may need to combine several cameras.
