have image sensors for color rgb black and white gray scale ir near ir and other wavelengths a ptz camera can operate in tandem with a fixed camera to provide a zoom in view and tracking over an extended area one scenario may be a ptz camera operating in tandem with one or more other fixed cameras another scenario may be one or more ptz cameras operating in tandem with one fixed camera each ptz camera may zoom in on a target in that several ptz cameras could cover several targets respectively in the field of view of the fixed camera the system may be a master slave configuration with zoom to target capability the potential target market is wide area surveillance with the ability to gather the relevant details of an object by utilizing the capabilities of a ptz customers are critical infrastructure airports seaports manufacturing facilities corrections and gaming an application may use fixed camera target parameters along with a relative master slave calibration model to point the ptz camera to look at the target the fixed camera will be mounted in the same vicinity as the ptz camera the master slave camera control relies on a one time calibration between the master and slave camera views the calibration step includes computation of 1 ptz camera optical centre 2 model for zoom as a function of a ptz camera zoom reading and 3 relative pan and tilt calibration between the fixed master and ptz cameras during the control operation for a given target in the master image or ptz wide field of view defined in terms of a bounding rectangle located centered at x y.
