A pan–tilt–zoom camera (PTZ camera) is a camera that is capable of remote directional and zoom control.
These are similar to the dome cameras, but they have a few more features. Consequently, they are also more expensive because of those features. The rotating head camera looks like a dome, but instead there is a small lens that can be maneuvered around by remote control. Some of them are hooked up to a special system designed only to operate the camera; more advanced models may be able to be accessed by a home computer. Some of the cameras have a feature to allow random rotation. They can be set to rotate at a specific time – or to just randomly rotate. If a vandal approaches a home or business with one of these cameras and has any knowledge of security devices, they will move on, knowing it is not worth the effort. The rotating head camera has all of its wiring securely protected inside the metal casing, which is shaped like a tall dome. At the end of the camera, the small lens head is made of durable material and protected since it is under the surface and recessed into the metal casing. This makes it difficult for the vandal to destroy it. When installed properly, these cameras are also very difficult to knock down, especially if they are well above head level. Most of these designs also have powerful zoom, so a criminal will know they can’t expect to outsmart it. In a continually-rotating head, the criminal will also have something else to think about – whether the head is automatically programmed or the owner is inside, making the camera turn. Either way, they do not want to mess with these types of cameras.
