Lack of maintenance is the most typical reason for poor image quality.
The most typical reason for poor image quality is lack of maintenance. With a dirty camera and light windows, the camera shutter speed is often reduced too much. This makes the real time image look good, but the camera can't stop paper web movement and recorded videos get blurred.
One way to reduce maintenance and camera cleaning efforts is to use the new 2020 introduced Procemex pinhole lens technology offering premium imaging quality with less cleaning efforts.
Web Monitoring field equipment should be under maintenance routines. In case help is needed, Procemex offers various service elements, starting from remote reports and ending to servicing the equipment under the service agreement.
