This unusual bullet camera takes the form of a ball within a bullet camera housing. This means it can be fully adjusted to any angle required and the ball can rotate within the housing so will even work as a side camera. It uses a quality CMOS sensor giving it a high resolution and usable night vision. It is ideal for mounting in the number plate area especially the strip that holds the number plate lights. The drill diameter is 18.5mm which gives you an indication of how small this is.
