2.2.4 Camera requirements
Mounting
The cameras must be mounted in a very stable way to avoid vibration and other
dynamic movement. The cameras can be mounted in any orientation to the image
area.
Lighting
Even lighting of the image area is very important to obtain reliable results.
Other camera requirements
If the camera is mounted on a moving conveyor then it is necessary to have a
progressive scan camera (non-interlaced).
We recommend using a camera that supports electronic shutter control. Then it is
possible to set the exposure from PickMaster PowerPac, otherwise the exposure
time must be manually set on the camera.
Camera configuration
Some cameras will need manual configuration to fulfill the above conditions. For
detailed information about camera settings, see Cognex manual and PickMaster
Release Notes.

Recommendation for lenses
When planning a cell it is important to choose a suitable camera/lens setup that
gives an appropriate field of view (FOV).
The FOV of a camera is determined by three factors:

• The distance between the camera and the scene.
• The focal length of the lens.
• The size of the camera's sensor chip (normally specified as the distance of
the diagonal of the chip, expressed in inches).
