Video security cameras are a useful tool for enhancing safety in public and/or secure areas. Surveillance camera systems are commonly used by retail stores, banks, casinos and other organizations to monitor activities within a given area. A security camera allows activity to be monitored for identification, for alerting the occurrence of unwanted activity or intrusions and/or for providing a signal that may be recorded for later reference or potential use as evidence. Typically, an operator of such a surveillance system is located at a central location from which he/she controls one or more camera units that are remotely positioned throughout the area to be monitored. The cameras are normally used to generate a video image of an area under surveillance that is displayed to and/or recorded for use by security personnel. The cameras are often provided with the capability to pan and tilt in order to acquire images over a wide range of areas. Pan-tilt-zoom (PTZ) surveillance camera assemblies commonly use stepper motors to affect the pan and tilt motion of the camera. Such assemblies often include a timing belt operably coupling a small sprocket attached to the motor shaft to a larger sprocket attached to the camera. Various mounting structures are provided for video cameras to be installed in or near buildings to be protected by a video surveillance system. The mounting structures typically include a housing that is secured to the ceiling of the building or at another suitable location on the building. The housing contains a video camera, motors and other components which permit the camera to be moved by remote control through a range of motion, and electronics for receiving control signals and transmitting video signals generated by the camera. Typical housing structures include ceiling domes or bubbles, angled ceiling mounts, flush ceiling mounts and the like. Other common mounting structures include pole or surface mounted housings that may be generally cylindrical, rectangular, round, oval, free form, or combinations thereof. Surveillance cameras are commonly mounted onto a wall, pole, ceiling or other fixed base positions by using an extended arm, known as a camera mount. The extended arm or the camera mount includes a swivel joint which permits the positioning of the horizontal and vertical axis of the camera in order to direct the camera lens toward its intended object. Video surveillance cameras are required to operate under a wide range of lighting conditions, from natural sunlight to indoor and outdoor manmade illumination.
