How to manually adjust the focus ring of a Dinion Thermal camera?


An object moving or a low/ higher contrast scene can throw off the autofocus option, resulting in a soft focus or even not focus at all.

Using manual focus is an obvious solution, but manual focus isn’t exactly easy to get sharp images.

Manual focus requires a bit of know-how and some practice to get right.

If you would like to improve the performance and get a sharp image, please see below how you can manually adjust the focus ring on a Dinion Thermal camera.


Step-by-step guide


  • Please make sure that your camera was calibrated correctly
  • Do some tests with people moving in front and behind of the field or with other reference objects
  • Please note that if you are not using 24VAC, the fan will not work properly and having no air flow inside the housing may cause heat build-up. which could affect the clarity of the image
