1. An aerial vehicle comprising:
a frame;
a motor coupled to the frame;
a propeller coupled to the motor and rotatable by the motor to generate a lifting force and a propulsion motor air disturbance;
a camera coupled to the frame and including a lens having a field of view;
a deflector coupled to at least one of the frame or the camera and positioned:
in front of the lens and in the field of view of the lens,
such that at least a portion of the deflector is beneath the propeller and within at least a portion of a path of the propulsion motor air disturbance; and
at an angle with respect to the path of the propulsion motor air disturbance;
wherein:
the deflector is configured to protect the lens and receive moisture; and
the angle of the deflector and the propulsion motor air disturbance are configured to cause the moisture received by the deflector to move across the deflector and out of the field of view of the lens.
