Motion tracking surveillance camera
Motion tracking cameras are able to track moving objects within their field of view. A computer controls motors that allow the camera to move side to side (pan), up and down (tilt) and zoom in on a subject without operator intervention.
Processor
PTZ motion tracking cameras are connected to a processor that analyzes anything that moves in the picture and follows that motion. Some cameras actually have the computer chip built into the camera, eliminating the need for an external processor.
DVR Processor
Some advanced security DVRs have processors in them that do the analysis and control the camera.
Camera
PTZ motion tracking cameras can be quite sophisticated. A separate motor controls the panning, tilting and zooming functions; these cameras can cost thousands of dollars. However, advances in technology have made PTZ cameras that are within consumer budgets.
Commercial Applications
PTZ motion tracking cameras are used to monitor construction sites, parking lots and other areas where little activity occurs.
Limitations
Motion tracking cameras have limitations. The biggest drawback is they are not able to track anything that does not appear in their field of view. Also, they are not able to follow more than one object at a time, making them useless in high traffic areas. Additionally, they often track and zoom in erratic ways and may not zoom in at the correct time, such as on the license plate of a moving car.
