Products Defined

PTZ means Pan, Tilt, and Zoom. PTZ dome security cameras differ from a fixed dome camera in that it can move left and right (pan) or up and down (tilt). These security cameras can also zoom in and out, making it very feature-rich. These domes require a keyboard and/or a DVR to operate PTZ functions. Using the keyboard PTZ domes can be programmed to view an area and can utilize alarm triggers to induce movement by the camera. A series of motions can be programmed by the user for the security cameras to follow. For example, PTZ security cameras can be programmed to sweep a parking lot every 10 minutes. Additionally, triggers such as motion detection or door contacts can alert the camera to reposition itself.

The total zoom capability of PTZ security cameras is actually a combination of digital zoom and optical zoom. Digital zoom uses electronics to zoom in and out while optical zoom uses lens motion. The total zoom of a camera can be calculated by multiplying the digital zoom by the optical zoom.

Like fixed domes, PTZ domes often are smoked or otherwise obscured, making it hard for people to tell if they are being watched. PTZ domes also come in a variety of configurations. Day/night capability means the security cameras are colour by day and black and white at night. They can be mounted almost anywhere using a variety of dome mounts, such as pendant and recessed mounts. A pendant mount allows the camera to be mounted from above. A recessed mount hides the entire camera except for the dome. Cameras using these mounts usually are mounted in drop or tile ceilings.
