Complete Camera Mounting

Complete Camera Mounting

Camera Mounting

After finished design, We go to the wood store and order they to custom made for us. When they delivered we mounted the camera to the middle and used a USB extension cable with USB hub with power plug. The reason that we used USB hub is USB 2.0 have a limit length of cable to 5.0 meters, So we used USB hub as a repeater of signals. The cable is mounted on the wood follow the arm to the top of the cabinet. 

Example of image from camera

Image from the camera

We used Logitech HD Pro Webcam C920 as a camera but FOV of the camera is not enough to cover the track, So we decided to used a wide lens to increase FOV and got a distorted image.
