1. A video camera assembly, comprising:

  • at least one of a pan motor rotatable about a pan axis and a tilt motor rotatable about a tilt axis;

    a video camera coupled to said at least one of said pan motor and said tilt motor, said video camera is rotatable about at least one of the pan axis and the tilt axis, said video camera subject to an oscillatory displacement due to at least one of a vibrational excitation from a source external to said video camera assembly and a source internal to said video camera assembly;

    an accelerometer coupled to said at least one of said pan motor and said tilt motor; and

    a controller communicatively coupled to said at least one of said pan motor and said tilt motor, said controller further communicatively coupled to said accelerometer and said video camera, said controller configured to;

    receive acceleration data from said accelerometer;

    determine an oscillatory displacement of said video camera using the received acceleration data;

    generate a motor angular modulation signal; and

    apply the motor angular modulation signal to at least one of said pan motor and said tilt motor to reduce the oscillatory displacement of said video camera.
