4:3 rectangles, but in all cases, best results will be obtained when the longest
dimension of the arena is parallel to the longer sensor dimension of the camera.
When the camera and lens are viewed as shown in the image below, the long axis
of the sensor is in the horizontal plane. This axis should be parallel to the longest
dimension of the experimental area.
The table below shows the horizontal and vertical angles of view that correspond
with maximum and minimum zoom of the camera, using the standard lens as an
example. Other lenses will differ.

Maximum zoom
(minimum angle and
area covered)
The best way to avoid optical distortions is to set the lens at Maximum Zoom and
move the camera far enough away from the experiment that the maze, cage, track
or other setup is completely imaged This is the optimum height. See figure below.
