Bullet cameras are very popular for their size and versatility. Things to
consider when buying a bullet camera are the resolution of the sensor, size of
lens (e.g. 6mm, 8mm) provided, whether it has a color image, black and white or
both and its weatherproof rating if used outdoors. Obviously the higher the
resolution of the camera the better the image quality but that should not be
your only consideration. The size of the lens must also be considered. It will
determine your field of view or viewing angle which can greatly affect the
overall image you see.
