The most advanced security camera in the market is a PTZ security camera. PTZ acronym stands for pan, tilt, and zoom. These cameras are equipped with motors for panning, tilting, and optically zooming the camera's lens. A PTZ security camera gives users 360 degree coverage from a remote location using a joystick or mouse. Panning allows a camera to rotate 360 degrees. By tilting, a PTZ camera can move the imaging sensor straight down to capture objects directly below the camera.
Some of the PTZ security cameras come equipped with long distance lenses which allow users to safely zoom in on distant objects without having to manually adjust a lens like a traditional camera.
There is a perception that PTZ security cameras would be ineffective without a user controlling the camera. Nowadays these cameras can be be configured to rotate without user input. This function is called a tour guard or location presets. Some PTZ cameras have sensor inputs which allow for the integration of external sensors which can trigger movement to a preset location. This means the camera can be moved to a predefined location like a gate or entrance when movement is detected.
In certain applications, one PTZ camera can replace several fixed cameras. They can be mounted from the ceiling using a pendant mount to maximize the coverage area around the camera. Other mounting options are available. Horizon PTZ cameras sit at the top of a pole with a pivoting head which allows the camera to view above the horizon. These types of cameras are typically used on an airport runway where a camera might need to view above eye level. Horizon cameras can also point down but unlike a traditional motorized camera, it is limited by the pole its mounted on.
