Dome cameras are half spherical shaped cameras that are often used when discrete applications are needed. Dome cameras are typically used for indoor applications. It is hard to know when a dome camera is recording you because the dome can be smoked or tinted. Because of this, they are favored by many commercial industries, such as the hotel and casino industry. Domes come with fixed or varifocal lenses and some domes come equipped with LEDs for nightvision capabilities. They are therefore extremely versatile cameras.
