A video surveillance camera enclosure that includes a camera housing for receiving a video surveillance camera chassis through a lower end. In one embodiment, the housing is adapted to be inserted into an opening in a ceiling member and includes a flange near the lower end and a plurality of mounting clamps for engaging the perimeter of an opening in the ceiling. The video surveillance camera chassis includes a plurality of positioning members on the perimeter of the chassis. The positioning members are engageable with a plurality of alignment flanges on the interior of the housing to guide the chassis into a preselected position within the housing. Final insertion of the chassis into the housing and electrical connection via blind mating connectors is by threaded fasteners on the positioning members and flanges. In an alternate embodiment, the housing is installed in an enclosure that is not installed in a ceiling but is self-contained and can be located outdoors. In the outdoor installation, a heater and fan assembly can be connected to the chassis. Selection of an address for installation of the camera can be accomplished without the need to disassemble the dome assembly. LEDs can be viewed from below the camera chassis for installation and service.

Integrated enclosure for video surveillance camera

A controller for a video surveillance camera enclosure including a method and apparatus for controlling a stepper motor by decoding a command for a specific camera action, setting the state of a state machine, and instructing a position control process and a speed control process based upon the state of the state machine. A drive signal is send from said position control process to a motor current process and a phase control process to generate the current and phase signals to control the stepper motor. The stepper motor drive current is preferably a non-linear current. The speed control signal includes ramp up and ramp down speed control for gradually increasing motor speed and gradually decreasing motor speed, respectively. Another aspect of the invention detects a plurality of pan and/or tilt positions to reset the pan and/or tilt motor step count to a known count associated with a known location without the need to pan and/or tilt past a preselected home position. Another aspect controls a dome enclosure heater to operate over two different thermostat ranges to provide for manual de-fogging of the dome bubble.
