Adjustable camera with belt tensioning apparatus

A camera assembly including first and second rotating members and a motor assembly defining a first axis and operably coupled to first rotating member to drivingly rotate first rotating member. A flexible member operably couples first and second rotating members such that rotation of first rotating member causes rotation of second rotating member. A camera is operably coupled to second rotating member such that rotation of second rotating member repositions camera. The motor assembly includes a flange having an outer circumference defining a plurality of teeth and bearing against a support surface. The outer circumference defines a radially variable distance from first axis such that rotation of outer circumference against support surface displaces first axis relative to second rotational member and thereby adjusts a tensional force in flexible member. At least one pawl mechanism is fixed relative to support surface and is engageable with outer circumference.
