Pan Tilt Zoom cameras and control equipment are typically used by large companies that have an on site security guard to monitor and control the Pan Tilt Zoom cameras.  Pan Tilt Zoom cameras allow an individual guard to monitor large areas from a single location.  These cameras can be programmed to conduct video guard tours and / or react to alarm conditions. Entire facilities can be monitored with just a handful of PTZ cameras.   Pelco a leader in the CCTV industry produces a fine line of Pan Tilt Zoom cameras and control equipment.  Pelco is PPSS, Inc. preferred vendor for PTZ cameras and controls.  For more information about Pelco visit their web site at www.pelco.com.
