Not all CCTV cameras are the same size and shape. Different uses require different capabilities, and so there are different kinds of cameras to meet those needs. The following table shows the three basic types of cameras and some of their common uses.

CCTV Camera Type

Use

Bullet Camera These small cylindrical CCTV cameras are often used in environments where discretion is important, but there is no need to permanently install the camera in a protective dome. They work well in shops and service areas when there is a need to monitor the staff
Dome Camera A CCTV dome camera is an excellent choice for surveillance as it not only protects the camera from casual vandalism, but also provides a degree of security as it is often impossible to tell where the camera is pointed
IR Day/Night Camera While obvious in appearance, these cameras have the advantage of providing 24-hour outdoor coverage regardless of lighting conditions. They provide a colour image in the daytime, shifting to black and white for infrared viewing at night

Which camera a given buyer wants to use depends on their goals and needs. Understanding those needs make choosing the right CCTV camera that much easier.
