1. Introduction
The oCam-1CGN-U is a Global Shutter, 1 Mega pixel, Color, UVC compliant, USB3.0 SuperSpeed
camera from WITHROBOT Inc. It uses AR0134 of On Semiconductor as the image sensor and
provides the image through USB3.0 interface to be easily connected to hosts with USB3.0 ports.
The camera is backward compatible with USB2.0 interface so for the hosts with USB2.0 ports the
connection is automatically adjusted to High Speed interface.
As the camera supports UVC1.0 specifications, the images of various resolutions of 1280 x
960(45FPS), 1280 x 720(60FPS), 640 x 480(80FPS), 320 x 240(160FPS) are readily available to
hosts of Linux or Windows operating systems without any special drivers. The electronic global
shutter mechanism of the camera provides clear images with less blur. The oCam-1CGN-U with
M12 lens holder allows various M12 lenses to be interchangeably used on the camera to suit to
various applications.
