# In-Sight Device Setup

The process of setting up an In-Sight vision system depends on its model type.

- In-Sight 3D-L4000 Series Vision Systems use a speckle-free laser line generator coupled with an image sensor for measuring objects. See the Setting Up 3D-L4000 Series Vision Systems topic for more information.

Note: For more information about installing and connecting your vision system, refer to the hardware reference guide of your Cognex hardware.
