<p>Ensure a sharp image of the camera by adjusting the focal length of the ESP OV2640 camera. <strong>Adjust the focus for the clearest possible image!</strong></p>
<p>In order to use it for reading a meter, the focal-length of the OV2640 camera has to be manipulated, as by default it only results in sharp image for distance bigger than ~40cm, causing the image of the water meter to be too small for automated readout processing.</p>
<p><strong>ATTENTION:</strong> this modification will void any warranty, as the sealing of the lens objective is broken!</p>
<p><strong>ATTENTION:</strong> This modification will render the camera unsuitable for general, web-cam type applications unless the focal length is changed back to the original setting.</p>

<p>Remove the fixing glue of the OV2640 lens with a sharp knife. After this you can screw the lens in and out. Rotating it by about a quarter of a turn counterclockwise results in a focus plane of about 10cm. You need to figure out your best setting with a little bit of trial and error for your specific environment.</p>
