See video for demonstration.  Includes power cable and serial cables so you can use it right away!  You must be careful with the extension of the arm, The gas cylinder is worn out and it will drop to the bed if not careful.  Make sure it is fully extended upwards and carefully lower.  However, the clarity is great, see video for demonstration of the device you will receive.  You can purchase an adapter to convert the serial to an hdmi out if you would like to, as it does not have a native HDMI out port.
